how to create extra post thumbnail with merge of an icon image?
I am searching a way to merge image of play button icon to featured image of the post. Bay be possible between add_image_size process.
if ( function_exists( 'add_image_size' ) ) {
add_image_size( 'post-play-icon', 90, 62, true ); //(cropped)
} | Personally, I wouldn't take this route. Instead I would apply a PNG client-side, using CSS. This has the advantage of allowing you to swap out your play icon as you see fit. | stackexchange-wordpress | {

Conditional check to see if a bootstrap.css is included in a theme
I am creating a shortcode plugin for Bootstrap framework that will go along with my theme. However since this would be released to the plugin, if a users's theme already has Bootstrap.css included, is there a way for me to check this from a plugin? | You _might_ be able to use `wp_style_is()` to do this:
$style = 'bootstrap';
if( ( ! wp_style_is( $style, 'queue' ) ) && ( ! wp_style_is( $style, 'done' ) ) ) {
//queue up your bootstrap
wp_enqueue_style( $style, $path_to_bootstrap, $deps, $ver, $media );
}
This comes with all the same caveats as @Milo's solution -- it'll only work _if_ the copy of bootstrap.css was registered or enqueued with a handle of `bootstrap`.

Featured Image inserted through custom query, does not show up
I need to transfer all my records from OpenCart to WooCommerce powered WordPress site. I used custom query to insert the image urls from opencart db to wp_posts as attachment and guid as the URL of the image, along with post_parent being the product id for that particular image. While the listings show in Media, it still does not load show images and also does not appear on Featured Image box of related products. But if I copy the url from Media manager and open it in new tab. The image shows up just fine. What could be the reason?
Also is there any other way to transfer OpenCart data to WooCommerce? Any help would be appreciated.

Show recent posts in a table format
In the index.php template I want to display posts in 3columns in a table format. How can I do this? I don't want a list format cause I have variable hight image sizes | You still can use lists - just use proper CSS (every third li - first li in every row - should have `clear` property set; You can use CSS classes or :nth-child selector to do this).
If you really have to use table (I don't suggest it - it's not a very good idea, because it's not semantic), you can do something like this:
<table>
<?php while ( have_post() ): the_post(); ?>
<php if ( $wp_query->current_post % 3 == 0 ): ?>
<?php if ( $wp_query->current_post ): ?>
</tr>

<td>

remove a single post_meta
I created a plugin that has multiple meta boxes. One meta box saves a single record by using `update_post_meta()`. Another meta box saves multiple record by using `add_post_meta()`.
I do not have revisions turned on in the post_type.
How would you `delete_post_meta()` a single specific record in the meta box that uses `add_post_meta()`? Best practice advise is needed.
If you're going to send the whole `$post->ID` and it will get the array of records, how can I detect the specific `meta_key` set to be deleted?
Here is the code on github: < | I'd say there is barely enough information in the question to speculate on an answer but it sounds like to me that...
If your data is saved in individual key/value pairs then `delete_post_meta` will do it. You would pass the function a post ID and a key name: `delete_post_meta(1,'keyname');`. It will delete the whole key/value pair.
If you have multiple bits of information saved as a serialized array/object then `delete_post_meta` **_will not work_**. You will need to pull the data for the key you want with `get_post_meta`, alter the array/object in `PHP` to remove the key/value you want to delete, and then save the altered data with `update_post_meta`.

Get background color for Live Preview with Theme Customization API?
This could very well be a stupid question, but I'm working on a WordPress theme (check the link to see what I'm talking about, then read on)...
You'll see the Post Formats icons are surrounded by a white circle, which has a border color matching the custom background color. I know that Live Preview includes background color by default, but I'm wondering how to change this border color with the background color, as they need to match.
Really, I just need to know what setting I need to use with `postMessage`, or if such a mechanism is possible at all.
Thanks for any and all help! I know it's a quite unique situation, since I can't find anything remotely close to the topic here, on Codex, or Google, or anywhere. | If you're using the built in custom background stuff, it's already all using postMessage.
So, just bind a function to the `background_color` message and adjust your border color accordingly.
Something like this, I expect:
wp.customize('background_color',function( value ) {
value.bind(function(to) {
jQuery('whatever').css('color', to ? to : '' );
});
});
Obviously, change the jQuery call in the middle to adjust whatever you're trying to adjust.

creating a second image attachment template?
Hi i am trying to create a second image attachment template. I have one, but I have created another. In the second one I want the attachments that are under a certain category of a post to have a different view from the rest.
Here is what i have in the nomrmal photo attachment page to try to call the category
<?php
$post = $wp_query->post;
if ( in_category('4679') ) {
include(TEMPLATEPATH . '/bet-photo.php');
?>
but the problem is, It's still showing the old attachment page and not the new one. What am i doing wrong. | `attachment.php` is not the only template file for attachment display. mime-type based template files get priority.

>
> <
I expect that that is the issue you are seeing. Check your theme for `image.php`.
There is a further problem with your code. Attachments don't have categories as far as I know. The category is inherited from the parent post. That means that you will need to pass the parent post ID to `in_category`.
if ( in_category('2', $post->post_parent) ) {
get_template_part('bet-photo');
}
I would also suggest `get_template_part`, as in my version of the code, instead of PHP's `include`. | stackexchange-wordpress | {

How to get new post URL?
I'm wondering... how can I get the new post URL in my theme? Is there a built-in function for this?
So, it should return something like <
Connor. | admin_url('post-new.php');
The `admin_url` function will handle generating most of the link, you just need to give it the final component. You can pass in `GET` parameters as well. Just look at the backend URL to see what you need.
admin_url('post-new.php?post_type=page');
Or using `add_query_arg` as suggested by @Rarst ...

Media Library page super slow, loading up full quality images
On my WP site (which sells retail products), I have large images (up to 4000x4000 px) so people can zoom in. Unfortunately, when adding images to a page and using the Media Library, the images all load up at full quality (though resized down). This makes the Media Library page load up really slowly, and make my browser slow to a crawl. Why is it doing this? Why isn't the ML page using thumbnails?

Get meta field value of all catgories

if (isset($cat_meta['color'])){

$cat_meta = get_option( 'meta_field_' . $category->slug );

count number of user comments with a specific comment meta value

Do not show on homepage functions.php code needed
I'm using a plugin called Float Left Right Advertising however I don't want to work on the homepage.
I tried adding this code into the functions.php but it doesn't work:
add_action( 'float_left_right_advertising' );
function float_left_right_advertising() {
if ( is_home() ) {
wp_deregister_script( 'float-left-right-advertising' );
}
Can someone please help me with this? | I don't think your code should work. You have to `add_action` to some hook (this function takes at least 2 params and you only use one of them).
add_action( $tag, $function_to_add, $priority, $accepted_args );
Also there is no script called `float-left-right-advertising` registered by this plugin.
Something like this, on the other hand, will work:
function disable_flradv() {
if ( is_home() || is_front_page() ) {
remove_action('wp_footer', 'append_code_to_body');
}
}
add_action('wp', 'disable_flradv');
PS. You also have to be careful, if you want to use `is_home` (and so on) functions. You shouldn't use them before `wp_query` object is initialized. | stackexchange-wordpress | {

How to update theme from localhost to online site
I am currently working on a project, actually we have an online site, we are thinking of revamping this. On this online site we have many blogs already.
We have purchased a theme also and doing many customization on `localhost`.
How is this possible to update the theme with customization and pages on `online server` from `localhost` without affecting the blog posts? | This depends on your set up. You essentially have two things to move, the Files (images, css, js, php) and the Database.
Moving the theme files is easier, I tend to zip all the theme files on `localhost` (wp-content > themes > your theme) then install it on the live site under themes > upload which lets you add the zip.
EDIT: You can also use ftp to move the files but it seems to be slower and not as clean.
Now moving the database which controls the pages and menus things get a bit more tricky. It depends on a few things,
* **If you don't have any data on the live site** (or want to start fresh) you can simply move the database but **you will lose all other data on the site**
* **If you have data on the live site** you can use the export then import to move post and pages however this will not move the menus.
* I typically recreate the pages/menus on the live site then add the theme.

How to redirect non-logged in users to login with post_password_required()
I have created a membership site which is working how I would like in that non-members cannot view private pages.
However, I want that when someone who has not logged in, clicks on a link that links to a private page, they should be directed to my login page.

User accounts for saving form data?
I have a handful of forms on my WordPress site that people fill out, sometimes repeatedly.

Have lots of meta for posts, is it better to get at all at once or each individually
I have a directory website and am doing a bit of a redesign/restructure. I have quite a few meta fields for each entry, i.e. address, city, country, website, where to buy their products, social links, background and so on.
I don't display all the meta data in the same place in my layout. So my question: Is it more efficient to use `get_post_meta($id,$key,false)` and have all my meta values stored in a `$variable`, or is it better to get each individually?
I would assume it is the former, but wanted to get some feedback. | Assuming you're retrieving the posts using a standard WP_Query in some manner, then the postmeta data is automatically retrieved for all the relevant posts and cached in memory. When you later call `get_post_meta`, the data is simply returned from here.
So honestly, it doesn't make any significant difference which approach you take. The `get_post_meta` function isn't making database calls unless the data isn't in memory already.
If you're making a WP_Query and have no need to cache the postmeta info, you can set the `update_post_meta_cache` argument in the query to false. Similarly, you can set the `update_post_term_cache` to false to prevent it from caching relevant terms from the taxonomy system as well. These can speed up a query for specific cases where you know that you don't need the meta/terms in advance. | stackexchange-wordpress | {

comments_template not working correcly in custom template files

Which database table does "Featured images" save under?
I'm having an issue while upgrading WP from 3.2.1 to 3.5.2, where one section's Featured images have all been deleted.

My images are still there, but the links to them don't seem to exist in the database. | The featured image itself-- the actual `.jpg`, or `.png`, most likely-- is saved to `wp-content/uploads` with primary image data saved to `$wpdb->posts` as an `attachment` post type.

What makes an image "featured" or not is an entry in `$wpdb->postmeta` under the key `_thumbnail_id` and a `post_id` field matching the post ID of the post for which the image is a "feature"-- aka thumbnail.

* The form then removes the oldest link

* Filtering the output of said Link Manager widget
* Creating a custom post type called 'Sidebar Links' and then writing your own widget that displays the 5 latest
* Creating a totally custom interface and storage mechanism from scratch (definitely not recommended)

The theme creator is MANUALLY inserting the more button (as you can see). You could just remove the paragraph containing the More button, or replace their custom function with the native functionality (both given).
If you plan on updating your theme ever (which I recommend you do), I strongly recommend creating a child theme, which is explained thoroughly here, and do any file/style changes there, instead of the theme itself.

'top'
);

Adding [...] string for a custom excerpt function
My blog is photo-oriented and the theme has a special excerpt function that, for better or for worse, I'd like to keep using. Anyway, it displays the excerpt and then the "More", but it just completely cuts of the excerpt, which I think looks a bit odd, especially mid sentence.
Not really sure what kind of change has to be made here, and would if go into the custom excerpt function itself, or as a separate function called by the excerpt function? | I have a custom except function I use all the time, it will cut off in the middle of a sentence, but it works great.

How to pass custom parameter to WP_Query for filtering in pre_get_posts
I have an ajax request that returns the result of a WP_Query loop.
I would like to detect in pre_get_posts filter the specific wp_query instance that is used in the ajax handler.
I thought placing a custom parameter in the $args of the WP_Query in the ajax handler:
$args= array(...,
'ajax' => 'AJAX',//custom param for detection of specific WP_Query instance
....);
and by this way detecting the specific instance in pre_get_post:
if(isset($query->query_vars['ajax']){
Do stuff
}
I do not know if this has any sense to you...
Thanks¡¡ | You can access query variables (including custom ones) via the `WP_Query::get()` method.
For example:
$my_query = new WP_Query( array(
...
'wpse105219_custom_var' => 'foobar',
...
) );

add_action( 'pre_get_posts', 'wpse105219_pre_get_posts', 10 );
function wpse105219_pre_get_posts( $query ){

Cannot change Connection Information in admin interface

Localhost wordpress access remote db wordpress website

Where is the right .mo file inside the language repository?

buddypress/
mu/
rosetta/

1. Create a directory called languages inside wp-content .

Does update_comment_meta hook exists?
Its been 3 days now I am fighting to resolve the issue here:
An action hook where a comment meta is updated
I am pretty sure, even if I am a beginner, that the hook `update_comment_meta` doesnt exist, and that it is not possible to use something like:
add_action( 'update_comment_meta', 'do_soemthing', 10, 4);
Any confirmations, or objections are highly welcomed. | Well, it's a little bit complicated ;)
If you will search `update_comment_meta` hook, you won't find it.
But it exists :)
There is `update_comment_meta` function and it calls `update_metadata` function with first param set to `comment`.
This `update_metadata` function does something like this (meta.php line 149):
do_action( "update_{$meta_type}_meta", $meta_id, $object_id, $meta_key, $_meta_value );
where `$meta_type` is the first param of this function.
So it will be `update_comment_meta` when this function is called by `update_comment_meta` function (because `$meta_type` is then equal to `'comment'`). | stackexchange-wordpress | {

Create custom markup to use in posts?
Is there some way - a plugin, a technique, some file to edit - to define some custom markup to be interpreted, parsed and replaced with custom, generated content when generating posts?
The simplest example of what I want would be smileys, getting a `:)` or in text of the post replaced by a specific `<img scr="...">` when generating the HTML, or custom version of BBCode, but in my case the generated content would be more complex, at the very least requiring the use of the post ID, but probably more, so I'd prefer a PHP-side solution working somewhere under the `the_post()` surface, not a simple client-side Javascript rewriter. | You are probably looking for The Shortcode API that allows to create shortcodes like `[my_shortcode]` and `[my_shortcode]some text[/my_shortcode]` to be used in content and other shortcode-enabled areas.

Previous and Next Navigation buttons take the user to the wrong posts

How can I sort homepage by a meta value?

$query->set( 'orderby', 'meta_value_num' );

}

}
When I use the above function, the homepage query is not returning all the posts and not ordering them properly; I am trying to figure out if it I am going about this the correct way. | You probably also need:
$query->set( 'ignore_sticky_posts', true );
That will prevent sticky posts from shuffling to the top.
Maybe:
$query->set( 'posts_per_page', -1 );
If you are getting too few posts. `-1` means "all". You can use that to change to a number other than what is set in the backend.
A couple of notes:
1. `$query->set( 'meta_key', 'key name' );` will limit the results to posts with that `meta_key`
2. If your `meta_value` for the `key name` isn't really a number the order isn't going to work correctly. Punctuation and letters will mess this up.
3. `is_home` can be peculiar. Make sure it does what you need it to do.

1) **Websites are made bythree layers**. Wordpress (like others good CMS) creates "only" TEXT menu because this is the (fundamental) semantic layer.

2) If you have understood the two points above, you can also understand that **is not so useful to generate on the server side two different html**.

$post_content = $post->post_content;

I took a look at the `WP_Query->get_posts()` function and couldn't see any action/filter that is called **AFTER** a query finishes.
I want to be able to manipulate the results once they are sent, rather than the query itself (Using a Human Name Parser to sort by last name).
I'm revamping an old site that alters the global `$wp_query->posts` right within `archive.php`, so I was just wondering if there was a way to take this logic completely out of the archive file and store it with my other CPT functionality.
Cheers! | The is the `the_posts` filter, which sounds like what you want.

Create a select drop down of available menus
I'm attempting to create a custom field on my page creation that allows a user to choose which menu to display on the page. Right now I have my custom meta field setup, but can't figure out how to make a drop down menu of the available menus. Is there a function that I could use and then for loop though?
Thanks! | It is not intuitive but `get_terms` will do it, if I understand what you need.
var_dump(get_terms( 'nav_menu'));
If you look in the `*_term_taxonomy` table you can see why. The menus are stored as a taxonomy named `nav_menu`.
This won't get you things like page menus, only the intentionally created menus. | stackexchange-wordpress | {

wp_enqueue_script does not work
I am developing a child theme based on the roots theme. I created a **front-page.php** and added the following. I test that the page is loaded because I see the I am loaded text. However, the scripts are not loaded. What is wrong with my setup?
<?php
function dd_register_scripts() {
wp_register_script(
'something',
get_template_directory_uri() . '/assets/js/something.min.js', array('jquery'), null, false
);
}
function dd_enqueue_scripts() {
wp_enqueue_script('something');
}
add_action('init', 'dd_register_scripts');
add_action('wp_enqueue_scripts', 'dd_enqueue_scripts');
?>
<div id="asd">I am loaded</div> | Based on your description that you "created a `front-page.php` and _**added the following**_ " and also that there is markup in that file, you are hooking too late.
You should be both registering and enqueueing on `wp_enqueue_scripts` but that isn't the problem here. The problem is that by the time you try to hook, the hooks have already fired. `init` will fire before your templates load at all and `wp_enqueue_scripts` will fire in the page header, which is before this code runs (or you have very broken markup). You can't `hook` to a hook after it has fired.
You need to add this code to the theme's `functions.php` with the appropriate template tags to conditionally load the scripts.

How to modify Media Library images DPI [ image quality down to make small in size ]
I wonder if there any code or hook out there to manage the image DPI, for example when we use photoshop or other image editing software we use export and image quality to 0-100%, now i am looking for a plugin or code to define the media library'r image DPI to make them small in size.
This is i want store two version one with smaller size[DPI] and one for HD quality.
Anyone Can help ? | DPI (as saved in image metadata) does not really apply to displays since pixel density is property of hardware.
You can fake this by resizing image with smaller dimensions in HTML, but saving with higher JPEG compression might make more sense.
Default compression level WP uses is `90` (out of 100) and it can be modified by filters:
* `jpeg_quality` (this seems to be legacy one)
* `wp_editor_set_quality` (in new `WP_Image_editor` class) | stackexchange-wordpress | {

What exactly is the description field when uploading an image?
This is a really basic question and I am slightly embarrassed I do not know, but what exact purpose does the description field serve, when uploading an image with Wordpress?
Typically when uploading an image I include a title (maybe) and some alt text. I always thought alt text was to help people with disabilities, so I try to always include it; I usually copy the alt text to the description (which I think would be bad practice), but I can't seem to 'see' the description text anywhere (whilst viewing source). Is it the same as `longdesc`?
Any help is appreciated! | If you click through to an attachment page-- `?attachment_id=123`\-- the Description works something like the post body of a normal post (which is basically what it is if you look at the database), or like a long format caption. Of course, I am sure themes can alter that.
I am not sure where else, if anywhere else, the description shows up by default. A theme or a plugin could use the information for other purposes. | stackexchange-wordpress | {

Why is my comment feed broken?
Here is my site. According to the WordPress codex, my comments feed should be Indeed, every post has that link in its header. However, it's broken. If you click on that link, you'll see that loading it returns a completely blank page.
My first question is, can anyone help me work out why it's broken?
Second, is there a good reason to keep the comments feed? Obviously the posts feed is important for a blog, but a _comments_ feed? | A "feed" is just another view of the site, really. If there's no matching items, then you'll get a 404 and an empty "view". This view can be expressed as a "no items found" on the front end of the site, while it will be an empty feed if looking at a feed view.
Since you had no comments, the query matched nothing, resulting in a 404 header status and an empty feed (which was a correct feed and viewable if you did a view-source on it). | stackexchange-wordpress | {

display custom field from inner blog in the main homepage of wordpress multisite
I'm using wordpress MU network and I have the main site and all the inner blogs. as people may know it is very hard in wordpress MU to make "relationship" between the main site and the inner blogs.
also there is not enough information and soutions on the web regarding wordpress MU unfortunately. (also posted this question and no one ever responded)

does anyone know how to do it? Thanks | Use `switch_to_blog( $new_blog_id )`, use `get_post_meta($post_id, $key )` to get the value of the field, and run `restore_current_blog()` when you are done.
You could use a site option (`add_site_option($option, $value)`) and store the values you need in an array there in addition to the post meta field. This would save the rather expensive `switch_to_blog()` calls. | stackexchange-wordpress | {

Is WordPress' is_user_logged_in() secure?
I've been wondering about this for a while. Is the following `if` statement safe enough? Is it easy to break through the code and get access to the content when not logged in?
<?php if ( is_user_logged_in() ) {
// SECURE CONTENT
} else {
// LANDING PAGE
} ?> | Well, you have to ask yourself "Secure enough for what?" I doubt you are a bank or other institution that needs exceptionally high security. If you were you'd a team of $100,000+ per year experts to answer this question for you.
With that in mind...
You'd have to subvert the WordPress login system to get past that code. I am sure that is possible but if your passwords are solid it should be pretty difficult. It isn't going to be a "put a null-byte in the query string" kind of a hack. It should be secure enough for most purposes.
On thing to worry about is that both `is_user_logged_in`, and `wp_get_current_user` upon which it depends, are both pluggable (nonsensically so to my mind) meaning that a malicious plugin, or just a badly written one, could completely destroy your security. | stackexchange-wordpress | {

"Blog pages show at most" in The Loop
I remember in another theme I did, that the The Loop automatically looped for the number that was set in "Blog pages show at most" (Settings->Reading). The theme I am working on right now does not see to consider this number and loops for an infinite amount of time (and crashes of course). How do I make it to consider "Blog pages show at most" ? | The only reasonable guesses that come to my mind are that the theme (or a plugin):
1. Modifies the main Query with a filter on `pre_get_posts`, so look for that filter.
2. Just creates a new Loop with `new WP_Query($args)`. You will have to dig through the template file to find out.
3. Interrupts the `post_per_page` save process or alter the `posts_per_page` option in the database, so check the `*_options` table for the `posts_per_page` key (option_name) to rule that out.
4. The Loop is not calling `the_post`. Without that, the Loop will never increment to the next post and the loop will run until the browser gives up.
I'd bet on #1, then #2, with #3 being a distant third. Without more information I can't give a solid answer.
Item #4 is a very viable option but the problem is not the query itself but the Loop. | stackexchange-wordpress | {

Correct way to make a title a link
I made the title of my post excerpt a link to the full content. It works but whenever I validate my website, the validator marks it wrong and shows the message below. I've switched around the h2 tags and it still didn't help.
**document type does not allow element "h2"**
The code looks as shown b elow
<span class="home-post-header">
<a href="<?php echo get_permalink(); ?>">
<h2><?php the_title(); ?></h2>
</a> </span><!-- End Home Post Header --> | Nice one for using WordPress, but this is a straight-up HTML question. Nontheless...
<div class="home-post-header">
<h2>
<a href="<?php the_permalink() ?>"><?php the_title() ?></a>
</h2>
</div>
`h2`'s are considered block-level, whereas `a` & `span` are inline. Standards dictate that a block-level element cannot be nested inside an inline one. So use a `div` instead, & place the `a` _inside_ the `h2`.
N.B: With HTML5, nesting block-level elements inside `a` is valid, but IMO use only when you need to wrap a link around several elements (for example, a heading with an image or snippet). | stackexchange-wordpress | {

Custom Query for searching through custom fields

So, how would I exclude 'draft pages' from populating the drop down?

How a deprecated function can crash WordPress site while upgrading
It is said that deprecated functions used in plugins & themes can crash a wordress website while upgrading to newer version, I want to see an example of deprecated function that can cause a crash.
Can someone show me an example?
Many Thanks! | ## Where...
The following files hold the deprecated functions:
* `~/wp-includes/deprectated.php`
* `~/wp-includes/pluggable-deprectated.php`
* ...
Take a look at them and then through their replacement functions, where the calls to `_deprecated_function()` happen.
## Why...
Normally a crash shouldn't happen. In the "real" PHP world, you'd get an `E_DEPRECATED` Warning. In WordPress you'll get a `trigger_error()` return caused by `_deprecated_function()` calls. The second `trigger_error()` argument isn't used, so it defaults to `E_USER_NOTICE` and won't stop your application from running.
## How to turn it off...
You can turn this off either by using `define( 'WP_DEBUG', false );` or by using a MU-Plugin that sets the filter to false:
<?php
defined('ABSPATH') or exit;
/** Plugin Name: (#105686) Turn off deprecated Warnings */
add_filter( 'deprecated_function_trigger_error', '__return_false' ); | stackexchange-wordpress | {

White spaces in username give 404 on author page
As the title says. When users register with white spaces in their usernames, if you try to go to their author page, you get a 404 error.
Is there a way to fix the redirect? or should I add a filter to prevent the use of white spaces in usernames? The site is new, so it wouldn't be hard to just change the one author with the issue.
I would think Wordpress would prevent people from having white spaces in their username. | Spaces are not allowed in URLs, so WordPress uses the `user_nicename` for those links. The user `nice_name` is "A string that contains a URL-friendly name for the user. The default is the user's username.". That is a transformed user name such that it is all lowercase with spaces replaced by dashes. I did not look up what other transformations are probably occurring.
Whatever is creating those links is doing it wrong. Without seeing the code that creates the links, it is hard to say more. | stackexchange-wordpress | {

Use WP_Query or query_posts() or get_posts() for optimizing a site?
I have read other answers, but I don't understand which is more fast (the best and simple for slow server running)?
I have a website with over 1 000 000 hits /day and a slow server with limitations at database connections, so I want to optimise my site.
What do you recommend me to use: WP_Query or query_posts() or get_posts()?
And if I want to show articles in different positions, with different styles can I repeat the function [WP_Query or query_posts() or get_posts()] on every article that I show, or it is best to use it one time and use if $i == 1,2,3 for different styles? | This answer explains the differences. They all use `WP_Query`, all parameters being equal there is no difference in speed, it's just a question of which is easier for you for your particular needs (hint: it will never be `query_posts`, which should basically never be used).
You should query the database as few times as possible, so if you can fetch all your posts with a single query, then do some manipulation via php to get the output you need, that is definitely what you should do versus creating multiple queries. Note that a `WP_Query` object contains some helpful vars to assist in output, like `$query_object->post_count` and `$query_object->current_post`.
You should also be employing a cacheing plugin, like W3TC, if server load is an issue. | stackexchange-wordpress | {
