<!--:fr-->french content<!--:--><!--:it-->italian content<!--:--> | What kind of special characters do you need to put?
I never used this field in Wordpress, so I'm not sure of what I am saying, but maybe it works like in HTML, which needs you to use entity codes for letters like à, é, è, etc.
Here's a link to a list of entity code : <

WordPress display name string manipulation
I have set the display name to show both first name and last name using the function below. How do I manipulate the LAST NAME to only pull the first letter of that string? Example, if you sign up as John Doe (First name= John, Last name= Doe), I want your display name to be John D.

Change Width of Featured Image Thumbnail on Add/Edit Post Page
Does anyone know of a way to change the width of the featured image on the edit post/add post page? I want to make it 50px wide. I'm not talking about the front page of the website, but the back end where you've selected the feature image and it sits next to your post as you're typing. Thank you! :) | Okey i think i understand what you want to do.
Here is a function that changes the html-output of the feature image in admin. It will look for the attached feature image ID and output it by using wp_get_attachemt_link() so you can change the size by the parameter $size. Here is a function that should work:
function wpse_111428_change_feature_image_admin( $content )
{
global $post;
$size = 100;
$id = get_post_meta( $post->ID, '_thumbnail_id', true );
if( $id )
{
return wp_get_attachment_link( $id, array( $size, $size ) );
}
}
add_filter( 'admin_post_thumbnail_html', 'wpse_111428_change_feature_image_admin' );

WPMU - new users are automatically subscribed to the main blog - how to prevent that?
New users added via `wpmu_signup_blog($domain, $path, $title, $user_name, $user_email);` are automatically subscribed to the main blog. Can this be prevented? I only want them to be administrators of their newly created blog.
I have no idea where to start looking for that as it seems to be some internal WordPress's mechanism that handles that.

How to get Menu Navigation Labels to output HTML
I'm trying to follow Jason Bradley's advice on how to style my Wordpress menus.
Specifically, I want to insert an icon before my navigation items using Font-Awesome.
I tried putting this code in the Navigation Label field for my "Home" link:
<i class="icon-fixed-width icon-home"></i> Home
However, when I view the page in my browser, it displays the HTML verbatim, it doesn't interpret the tag, or any other HTML I throw at it, for that matter.
Did Wordpress Menus change in 3.6? Am I missing something obvious?
I know that my font-awesome installation works because I am using their icons all over my site. Thanks. | The "Navigation" field is _not_ where you want to place your CSS class. The navigation is what the user will see in the menu, so don't put any code there.
To enter a custom CSS class to your item, you need to do the following:
* Click the "Screen Options" tab in the top right corner of the page.
* Under "Show advanced menu properties", tick the "CSS Classes" checkbox.
* Now for every menu item, you have a field labelled "CSS Classes (optional)" where you can enter "icon-fixed-width icon-home".

Pods custom type integration with navigation menu and current_menu_parent
I have a Pods type called `project`, and a Pods pages url as `project/*` (which links to a template to show the project).
I also have a normal Page which lists the projects (via a custom shortcode that loops through all the pods) and outputs on the page.
My navigation menu is simple: Home, About Us, Method, Our Work, Contact Us.
I need further guidance please on how to link up the Pods `project/*` page so that when a specific project is being displayed, the top level Projects link is highlighted with the correct wordPress class `current_menu_parent`.
Also where should the Pods page be listed in the Wordpress Appearance -> Menu, as I see no link there for the Pods type.
How can I do this please?

Spams, Scams on WordPress site - what to do?
Suddenly our hosting company complaint our boss with a google mail that saying something like:
> **Your site is full of spam/scam. Please remove such malicious thing or we will unlist your site.**
That made us crazy. We found some links in our WordPress site is taking us to a page, that is obviously NOT our site-page. But with the same URL of our page (domain/my-page) it's showing someone other's contents - that's disturbing too.
We tried the cPanel's "Virus Scanner" to find any trace of virus attack to the site, but found nothing.
Then, one of our developer found a way to generate a new page for the content of that page with a slightly different slug, and that worked. But after days it's worthless.
How can we get rid of such spam/scam? | One of our developer Mr. Ahsan Ullah found a very normal solution to that: He simply **Refreshed the Permalink settings** and it's all set.
From `/wp-admin`, going `Settings` » `Permalinks`, he clicked the `**Save Changes**` button. The permalink structure of the whole site was refreshed and the unwanted links were vanished from the site. | stackexchange-wordpress | {

spacing disappears on posts when importing
This is a random question, so I'll be lucky if there's an answer out there.
I imported this wp site from another location, and for some reason, none of the posts show spacing between paragraphs anymore. If you look at any post, you'll see there is no space between each paragraph. In the actual post, on the backend, the spaces are all there. Each paragraph has a nice space between it. On the actual site, the spacing disappears. What gives?
This is the case with all of her posts, so I'd be just delighted if there is some solution to the issue.
it's at: www.travelwithcastle.com and it's a twentytwelve child theme
Kelly | As Sven noted in the comment, your theme doesn't have any spacing after paragraphs. It's actually set to no space between paragraphs on line 797 of your style.css. If you were to change that line and the one above it so the last numbers in each line were 10px and 1rem, you'd have fairly default spacing back.
The spacing in the admin is controlled by a different stylesheet, likely the default one in your case. | stackexchange-wordpress | {

two sites, same code, different presentation
I have created two web sites. One is "production" and the other "dev". Each is a virtual host and both are on a single server running apache. Both sites are loaded with the same code base: WP 3.5.1, a base theme and a child theme. This is not a multi-site setup; just two sites loaded in different directories.
The page in question uses a page template. In the page template there is some switching in PHP code to choose what to display. The switching is based on the $current_user->ID. If ID is null or zero display a logon block otherwise look up some data to present.
This works fine on the dev site. It does not work on the production site. Something is different. I checked .htaccess, the virtual host declaration in apache, and the settings for WP and the theme. They all appear to be the same. I have run delta checks on the code and the two sets of files are identical.
What other config settings might be in play here? | After walking through the code and examining everything else, I (finally) revisited the page definition in the Dashboard. There I noticed that the page was not associated with the page template I was working with. I assume that during the migration from the development web site to the production web site, the association went missing.

Given a page ID, how to display entire page (header/content/footer/sidebars) from a plugin hook
Given a page ID it it possible to display the page content from within a plugin hook.
I would like to know if it is possible to display the **_entire_** page given a page ID (Header/Footer/Sidebar/Content/etc..)
For example, if the Page ID "123" is the "Home" page then the output from `render_entire_wordpress_page(123);` would be identical to visiting the normal "Home" page. If the Page ID "321" is the "Blog" page then the output from `render_entire_wordpress_page(321)` would be identical to visiting the normal "Blog" page.
Is this possible?
I can somewhat achieve this by filtering `rewrite_rules_array` and then flushing, however I'm trying to output this content after all rewrite rules have finished processing. | > I would like to know if it is possible to display the entire page given a page ID
Yes, ` or ` Request that address via AJAX or the HTTP API.

add_user_meta() vs update_user_meta()

## update_user_meta()
returns **False** if no change was made (if the new value was the same as previous value) or if the update failed, umeta_id if the value was different and the update a success.
**NOTE: as of v3.4.2 it returns the umeta_id on success (instead of true) and false on** failure

return **Primary key id for success**. No value (blank) for failure. Primary key id for success. | stackexchange-wordpress | {

loss of theme options while site deployment in production
i have moved both wordpress folder and the development database on a distant server.

What does short_ping do?

Can someone tell me where I can find more information? | If the comment is a pingback or a trackback and short_ping is `true` then the comment is processed by the `ping` method which formats the comment differently than either the `html5_comment` method or the `comment` method both of which create a much longer more complicated format than does the very minimal `ping` method.
You can kind-of guess what it does by the name of the variable, really, but when in doubt there is no better source of information than the source code itself. | stackexchange-wordpress | {

Listing registered scripts
Back story : We have a number of wordpress web sites experiencing issues when viewed on _some_ IE8 browsers.

So to the questron : is their an API call that will list the handle of every front end registered script?
I have a back-up of the site's including themes and plugings so I could grep them but I may well miss something and, being lazy, I was hoping I could get wordpress to generate the list for me. | There's a global variable called `$wp_scripts` which is an instance of the `WP_Scripts` class. It doesn't have a public API for looking at registered or enqueued scripts, but you can look inside the object and see what's going on.
You can see all the registered scripts with:
global $wp_scripts;
var_dump( $wp_scripts->registered );
To see the enqueued scripts:
global $wp_scripts;
var_dump( $wp_scripts->queue );
You'll want to run this after all your plugins & theme have had a chance to register their scripts. Maybe as part of a wp_footer handler.

Create gallery doesn't show uploaded images
When you do Add Object in a page, for example, a screen is shown where you can see your uploaded images. But it doesn't work for me. No images are shown. What can it be due to? If I open the Multimedia Library the images are there.

How to change archieve frequency of the media file in uploads folder for wordpress blog
So far I can see my media file is divided into month and year as 2008/09 like directory.

$y = date('Y');
$w = 'W' . date('W');

Should I use include or load_template for including shortcodes, plugins and so on?
I am wondering what is the right way to include additional php files for theme options, shortcodes, plugins and so on.
Both load_template and include will work, but what has better semantic value?
Thanks | `load_template()` is for cases where you need the following global variables in an included file:
$posts,
$post,
$wp_did_header,
$wp_query,
$wp_rewrite,
$wpdb,
$wp_version,
$wp,
$id,
$comment,
$user_ID
If you don’t need those, or if you use `global` in those files anyway, it isn’t needed.
`locate_template()` and `get_template_part()` are for cases when you want to allow child themes to replace the files with their own version. If you offer other ways to turn the loading off, it isn’t needed.
So, it depends on the context, on the position of your theme in the hierarchy (parent or child), and on the included code. You can use `require` if you want to. Avoid `require_once` and `include_once`, they are more expensive.
And shortcodes are not part of a good theme. :) | stackexchange-wordpress | {

Custom user roles for access to specific parts of the site

How can I make my blog urls have words of the title in them?
I just started a new blog and all the urls look like this:
sitename.com/?p=1
But how do people make the url have the title of the blog

force http canonical tag on https pages

users and usermeta table
Is it mandatory for each user to have entries in usermeta table as well or it's optional? Recently, I came across a wordpress database which has thousands of users in user table however only a few of them have entries in usermeta table.
I am wondering in what scenario this could have happened as it doesn't look like those entries were manually removed from database. | install a fresh wordpress setup on your local machine and then have a look at `wp_usersmeta table .` It contains meta(additional) information for each user.You (admin) can also make data entry specific to any user by this function `update_user_meta()` in usermeta table. and retrive the same using `get_user_meta()` funciton.
All fields for all users are not necessary. meta keys can be user specific also.

Problem in register activation hook and Copying folder
Hy Guys, I am wanting to copy a folder to activate my plugin, I'm trying this but it does not work.

$src = 'includes/myTheme/';

Run "get_the_post_thumbnail" with a different table prefix?
I have this site were I run two Wordpress sites on the same database (with different prefixes), on one domain.
What I want is to get the post thumbnail from the second Wordpress installation, by running the function `get_the_post_thumbnail` (with a different table prefix), on the first Wordpress installation.
Simplified:
Two Wordpress sites, One database, Wordpress site "a" want to get a post thumbnail from Wordpress site "b" through the function `get_the_post_thumbnail`
I really hope this makes sense! | Why didn't you use a Network/Multisite install? Problem mainly is that all the queries normally have the current install prefix in use. Without having real access (via `$wpdb`) to the prefix, this will get pretty messy. Actually your problem is a X-Y Problem.

Wordpress link to show popup box

Rewrite category list as an if / else statement

How to force content refresh of a page that has been loaded previously by the user?
How can any page on the site be forced to refresh or load content by ignoring anything in cache, everytime a visitor visits the page for the second time? The website uses twentyeleven & w3tc (browser caching disabled at the moment). | Since, your site already uses W3 Total Cache plugin, let me provide a solution based on it.
Please visit yoursite's wp-admin/admin.php?page=w3tc_browsercache and look for the text "Set cache control header". Check this option, if it is unchecked, and then choose "no-cache" for the "Cache control policy". This needs to be done in three places...
1. CSS & JS
2. HTML & XML
3. Media & Other files
!enter image description here
If you do not wish to use W3 Total Cache plugin for some reason, you may set the following in 'htaccess' file or in Apache configuration, assuming your server has mod_headers module...

Site Crashes When Updating to WordPress (Version 3.6)
I was just clicking the update button behind in the admin panel. it said no enough space in my hosting. then i went and removed some files and tried again then it was processing the wp update. suddenly it took me to a blank page and now the entire site looks empty.
I am guessing this could be due to space limitation in hosting account. even though i removed a few and tried updating, it might have meet not enough space in the middle of updating and its leading to this issue.
Also in the mean time i tried accessing this page: `www.mywebsite.com/wp-admin/update-core.php` and got the below error.
> Fatal error: Call to undefined function nocache_headers() in /home/webmas8/public_html/azraar/wp-admin/admin.php on line 32
This is the website that causes the issue: < | Probably the update wasn't complete and some files are missing.
If you have FTP access, follow these steps.
1. Download you `wp-config.php` and save it somewhere.
2. In the wp folder on server delete everything **but** the wp-content folder
3. Have a DB backup, if you can
4. Download from wordpress.org the zip of wordpress and extract it
5. At this moment remove the `wp-content` folder from the extracted zip
6. Also remove the `wp-config-sample.php` and put there your `wp-config.php`
7. Via FTP, upload to server all the files
Now it should work, but probably you have to change hosting... | stackexchange-wordpress | {

How come my first blog post and my home page have the same title?
I am putting together a new blog and for some reason the home page took the title and description of the initial post. Is there a way to just set the home page title/description separately?
I am trying to edit it via YoastSEO, but I get this screen when I try to set my Home title/description:
!enter image description here
But what I was expecting was the form fields for title/description.
Thank you! | The "Reading Settings" at a domain's wp-admin/options-reading.php is, by default, set to latest posts. So, WordPress, by default, would show the title of the post being set at "General Settings" at a domain's wp-admin/options-general.php . In this case, Yoast's WordPress SEO plugin would have form fields to customize it.
When the "Reading Settings" are changed to show a static page as the front page, then the title of that page is shown as the title of the blog itself. This is the expected default behavior. Yoast's WordPress SEO plugin would have not any form fields, in this case, but would contain the link to the post to edit the title and the description. | stackexchange-wordpress | {

How to use author id in post permalink
Currently, Wordpress supports author name in the post permalink by using %author%.
Is it possible to add the author id to the permalink?
For example, changing this:
<
to this:
<
Where '1' is the id of the author 'john'. | You can do this with a couple of filters:
<?php
function wpse_112719_pre_post_link( $permalink, $post, $leavename ) {
if ( strpos( $permalink, '%author%' ) !== false ) {
$authordata = get_userdata( $post->post_author );
$author_id = $authordata->ID;
$permalink = str_replace( '%author%', $author_id, $permalink );
}
return $permalink;
}
add_filter( 'pre_post_link', 'wpse_112719_pre_post_link', 10, 3 );
function wpse_112730_add_rewrite_rules() {
add_rewrite_rule(
"([0-9]+)/(.*)",
'index.php?name=$matches[2]',
'top'
);
}
add_action( 'init', 'wpse_112730_add_rewrite_rules' );
Now, go to Settings -> Permalinks and set your permalinks settings to `/%author%/%postname%/`. Save your changes, and your links should be working accordingly. Let me know if you have any issues! | stackexchange-wordpress | {

Can Settings API setting generate other settings?
I have a Settings API field for an address. The address is stored this form: "Address, City, Country".

function ($oldvalue, $_newvalue) {
// process your option value and update/insert options as needed
// var_dump($oldvalue, $_newvalue); // debug
// wp_die(); // debug

WPML Get url without outputting
I am in the process of migrating from qTranslate to WPML to handle my languages.
With qTranslate, I had a very simple way to get an url to a page or post knowing it's slug: `$url = get_language_url(home_url($slug));`
Now with WPML I can't find a way to do that...
There's the `icl_link_to_element` function but it directly outputs the link in a a tag.. Besides, you need to know the post ID.
Any way I can get a link to a post in the correct language, knowing it's slug? | Actually Wordpress lacks a real function to get posts by slug/post-name. But you can use get_page_by_path() for it so you don't have to use a custom query:
if(function_exists('icl_object_id')) {
$post = get_page_by_path('your-slug');
$id = icl_object_id($post->ID,'post',true);
$link = get_permalink($id);
}
The only difference here is that you must use the full path i.e. (`'parent-page/sub-page'`) if you have a hierarchical structure. For posts and non-hierarchical pages you can just use the slug as param. | stackexchange-wordpress | {

Modify the main loop to display current month / year
So `pre_get_posts` seems to be the way to do this now - a lot of the background is nicely explained here: When to use WP_query(), query_posts() and pre_get_posts

$query->set( 'monthnum', 3 );
return;
}
}
add_action( 'pre_get_posts', 'loop_current_month' );
However, I would like to modify the loop for the current month, and the current year.
How can `$query->set()` take two vars? Something like:
$query->set( 'monthnum', 3 & 'year', 2013 );

$query->set( 'year', date("Y") );
