CSS not applying in admin
I am using SASS and grunt to merge all my seperate .scss files into a single minified css file, which is loaded using `wp_enqueue_style`.
Works fine across the site but not in the admin area. Is there a special function needed to enqueue scripts for use in the admin area? | You need to hook `admin_enqueue_scripts` to enqueue scripts and styles for the admin side. | stackexchange-wordpress | {

Changes only show when logged in?
Changes I've made to my site only show when i'm logged in. According to various other threads it seems to be a problem with cache, however, i've completely deactivated my W3 cache plugin, and the problem still isn't resolved.
Any ideas? | This does indeed sound like a cache problem. Plugins on the server side will cache the site for faster serving, while your own browser does its own caching to not have to repeatedly download the same web content.
In Wordpress, any caching plugin should have a "clear cache" button, and your browser cache should have a setting for deleting cache.
If you develop with your browser's developer tools open, your browser shouldn't cache. | stackexchange-wordpress | {

Issue On Displaying Pages with Post Name Permalink
I have a simple Theme like below
!enter image description here
Right now when I navigate to localhost and site root directory I am able to see content from `header.php` , `footer.php` and `page.php`.
then, I simply generated some pages for Navigation bar and to get a better URL I updated the permalink from `default` to `Post Name` format

Now while I have the the clean Ur as: `Permalink:

When I click to view the page I am getting !enter image description here
I Google this and find some hints about the `(.htaccess)` so I just copied same format as Cedex) !enter image description here
but still getting same result. Can you please let me know why this is happening?
Thanks | In order to work permalinks properly, you have to enable 'mod_rewrite' module in your apache server. Other wise it could not run .htaccess file and that is why it shows 'Not found'. It will be working if the permalink is disabled or set to default, right? | stackexchange-wordpress | {

Get the title before comma

add_filter('gform_field_value_page_name', 'page_name_filler');
function page_name_filler($value){
return get_the_title() ;
}
However, usually the title of the post is too long and it overfills the field. Hence I would only like to retain the first portion of the title before a comma "," if it exists on the title. Usually I will have multiple commas on my titles.
If a comma doesn't exist then the full title should be displayed. | Use `strtok()`:

Differences between wpdb->get_results() and wpdb->query()
Who can explain me the differences between `wpdb->get_results()` and `wpdb->query()` in making generic queries to wordpress db? | The difference, if you want to call it that, is that the `query()` is the most generalized method to do queries with `$wpdb`, the `get_results()` method on the other hand is a specific method, which does make use of the `query()` method to retrieve the specific results of this method and then does some work on the output. | stackexchange-wordpress | {

Using functions repeatedly instead of variables
I think I know the answer already but I would like some clarification on what exactly is happening in the back end.
Usually I call a wordpress function such as `get_post_meta($id)` and assign it to a variable if I wish to reuse it later on. What kind of performance hit would happen if I used `get_post_meta($id)` over and over again instead of the variable, say in an if statement or in a while loop? | The difference is going to be pretty minimal, I'd expect.
There is overhead to using the functions, which you could save by storing your output in a variable. (WordPress does a pretty good job at caching the queries though.)
And the variable is going to be more convenient as it is probably fewer characters than the function.
A drawback to using a variable is that code will not be able to hook into the functions if that code runs after you've saved the value to the variable, so that could potentially cause trouble.
I am going to answer "you probably don't need to worry about performance but there are other things to think about". | stackexchange-wordpress | {

how get comments only on post of current logged in user?
I need a query that get all comments from only the posts where the currently logged in user is the author.
Each user (author) can post a new post. Then I need to show a list of their own posts ( that already works). Now I want a list of all comments (on the currently logged in users posts). So the author has a quick overview of all comments on their posts. | Using the @shanebp ideas of using `get_comments`:
$args = array(
'post_author' => get_current_user_id(), // It will use the current logged in use to grab the comments

// Referer to
$list_args = array(
'reverse_top_level' => false // Show the latest comments at the top of the list
);

Disable Admin CP authentication (or auto login)

How do I link a Post Type to a Template in Masterplan?
I've made a new .php theme page and want to use that file on one of my Post Types. In the Templates part of Masterpress Ive added my Post Type in the availability section.
However, when I view my posts with that Post Type their theme doesn't change. I cannot see where to select the theme on the Edit Post Type page.
Does anyone know how I can select a theme for a particular Post? | I have never used Masterplan nor Masterpress, however as far as the template hierarchy is concerned, it seems to be no different from the standard Wordpress way of dealing with it - See Masterpress Docs
I assume that if your (Custom) Post Type is correctly registered through Masterpress interface, it should be registered in Wordpress.
So you probably just have to send your PHP template, renamed to `single-{post_type}.php` on your sever, in your current theme folder. For instance if your post type is registered under "trees" (take not-rewrited slug, or front-end name as it seems to be called in Masterpress), then your PHP file should be named `single-trees.php`
It should then be used automatically by WP when accessing a post from this Post Type. | stackexchange-wordpress | {

Best way to load WordPress Bootstrap
My script needs to load the whole WP in order to work probably. I'm currently doing it this way
if ( !defined('ABSPATH') ) {
/** Load WordPress Bootstrap */
@ini_set('include_path', '../../../');
require_once('../../../wp-load.php');
}
//additional html stuff
do_action('my_custom_hook');
//more html stuff
which works most of the time. Sometimes people get a Fatal error for a missing file though.
The script is located at
wp-content/plugins/my-plugin-slug/script.php
What's the best way to load it? | Requiring a file using relative path is never a good idea, that because wp content folder can be easily changed and that make your code fail.
You should convert your file into a MU plugin (you only need to save it `wp-content/mu-plugins` folder) and change it to something like:
add_action( 'wp_ajax_super_custom_stuff', 'my_super_custom_stuff' );
add_action( 'wp_ajax_nopriv_super_custom_stuff', 'my_super_custom_stuff' );
function my_super_custom_stuff() {
// additional html stuff
do_action('my_custom_hook');
exit();
}
After that, to make the script run, instead of calling the url
you can call
This will always work because `wp-admin` folder, unlike `wp-content`, can't be changed because it is hardcoded in a lot of places.
You can run the script from a linux crontab using something like:

How to search display_name column when using WP_User_Query
I'm using WP_User_Query to bring back a list of users. According to this article, I can focus the query on particular columns (I'm assuming in the wp_users table) using the search_columns param.
My query:
$args = array(
'search' => 'Rami',
'search_columns' => array( 'user_login', 'user_email', 'display_name' ),
);
$user_query = new WP_User_Query( $args );
My aim is to have my query look in the display_name column but that doesn't seem to be working. Interestingly, display_name isn't a mentioned column in the article example but it is definitely a column in the wp_users table.
How can I search the display_name column when using WP_User_Query? | You can try this:
/**
* Add support for the "display_name" search column in WP_User_Query
*
* @see
*/
add_filter( 'user_search_columns', function( $search_columns ) {
$search_columns[] = 'display_name';
return $search_columns;
} );
where we use the `user_search_columns` filter to modify the available search columns.
So what fields can we use with this filter? Here's the list of all the fields in the `wp_users` table:
x ID
x user_login
user_pass
x user_nicename
x user_email
x user_url
user_registered
user_activation_key
user_status
display_name
where I've marked the default search columns with an `x`. | stackexchange-wordpress | {

How to get post thumbnail to be equal to set media size
I'm new to learning WP theme development so I may not have worded the title perfectly but that's the best way I could think to explain it.
My theme is on a localhost so I can't link to it but here is a screenshot:
What I want is for the_post_thumbnail to always fill the specified thumbnail media settings.
Currently the thumbnails will be different sizes depending on the width / height ratio.
I have gone into WP Dashboard and set the media thumbnail size for medium at 250px wide by 150px tall. I want the image to always fill that space, don't care if it's cut off but I want it to be that size.
Thanks, I hope I explained it correctly. | the_post_thumbnail allows for size specificiations. So you would do:
<?php the_post_thumbnail('medium'); ?>
if you changed the image dimensions in the admin, you will need to go back and re-upload the images so they crop to the correct size that you set up
If the issue is the dimensions of the image you are probably looking for a hard-crop. The best bet is to set up a new image size with add_image_size in your functions.php.
add_image_size( 'new-image-name', 250, 150, true );
then re-uploading images then

Removing a page from the header menu
My site is using the Hemmingway theme, I have a menu in the header.
This is the menu whose structure results from assigning a "parent" on a page's edit form.
One of my pages is less important and should not appear in the menu. (It is accessible through links from the body of other pages.)
I went to Appearance->Menus (/wp-admin/nav-menus.php) and removed this page under the Menu Structure list (there is only one menu there, "Menu 1". Yet this page still appears in the header menu.
How do I remove it from the header menu? | I manually created a menu under Appearance->Menus and then assigned this as the Primary Menu.
This worked, but required me to manually reproduce the structure of the menu: The structure created by assigning a parent in each page's admin is now simply ignored. I would still like a way to use the default menu, which is generated straight from the parenthood relations, yet make modifications like omitting a page from the menu. | stackexchange-wordpress | {

Cannot use some themes within Managed WordPress of Go Daddy
Some themes display blank pages instead of my home page when I activate them. | Check to see if you have set up your site to use a specific static page as the site home page and another as the blog home page. If you haven't, the default is to show posts on the site home.
Next check to see if the themes include both index.php and home.php. Typically home.php is used for the home page of the blog, and index.php for the site home page with page.php being used for internal pages. If your site requires one of these templates and it isn't there, that could be the problem. Generally if home.php isn't there, then WP falls back on index.php. If that is the case then you want to look at index.php to make sure if is using the right WordPress loop.

What do you put in child themes author tag?
What is the common practice in authoring child themes ? I mean, if I make child theme of some free theme should I put myself as author or should I keep the name of the original themes author ? I searched quite a a bit but unfortunately couldn't find clear answer. | There are several scenarios:
1. If you had authored your child theme from scratch, using only your custom code then it is clearly **your** product.
2. If you had used code from parent theme in your child theme then it's **your derivative** of it, it's still yours but you **also** need to credit code used in line with its licensing requirements.
3. If you had taken third party child theme and modified it you usually choose between **keeping authorship and noting your modifications** (usually for private or semi–private use) or **renaming it** and treating it as derivative same as 2 (usually if you intend to distribute publicly).
In either case pay close attention to licensing requirements of original theme. | stackexchange-wordpress | {

Prevent Google from indexing custom post types?

Ordering WP_User_Query results by the user IDs used in the include parameter

Save re-arranged draggable post items to wordpress database

Change "en-US" to "en"
Hey I am trying to edit the WP theme files, and I am using `bloginfo('language')` to get the language of the page.
However, it returns me "en-US", which does not work while redirect the page. The site I am working on only accept "/?lang=en".
I have tried to use if statement to specify the solution under different situations, but it failed, it seems the theme used a complex loop method, a slightly change will make the functions does not work.
So could I ask if there is an alternative way to transfer "en-US" to "en", or get "en" directly from the browser?
Thank you. | If you want to get the language of the browser do so:
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
If you want to redirect to `?lang=en`:
header("location: {$_SERVER['REQUEST_URI']}?lang={$lang}");
You should read about **HTTP_ACCEPT_LANGAUGE**.
There are many ways you can _dance_ with languages but you should understand some key points.
1. Chose the default language of your website (French in your case)
2. The user may be French but his OS & Browser can be in English because he wants to learn the language of trade.
3. Create a cookie that stores the selected (or default) language so that you know what content to display. `$_COOKIE["wpse_166976_lang"] = "fr"` or `$_COOKIE["wpse_166976_lang"] = $land` where `$lang = get_query_var("lang")`

How to migrate .HTML pages to WordPress

The problem is that for pages this isn't a built in feature. Here is another question that might give you a hint: Add .html (dot HTML) extension to custom post types
The reasons why I proposed using redirects instead of changing the permalink structure are:
* You stay within defaults in WordPress which avoids unwanted side-effects and always makes it easier later on.
* Non-html URLs are more common nowadays (and more beautiful if you ask me, but this of course is a matter of taste)
In case you decide to go the redirect route you can add this to your `.htaccess` file:

exclude particular posts in archive.php
My archive file contains..

<a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a>
But i want to exclude few posts with their ids, how can i do that ?
Important! But those excluded posts should display in the Google search as normal, i don't want to loss them in the search engines. Just i want to hide in my site only.
Thank you friends. | You can exclude posts from archive pages with thee help of `pre_get_posts` action. Usually `pre_get_posts` is used to modify main query, so it's best solution for your problem.
function my_custom_get_posts( $query ) {
if ( is_admin() || ! $query->is_main_query() )
return;
if ( $query->is_archive() ) {
$query->set( 'post__not_in', array( 7, 11, 21 ) );
}
}
add_action( 'pre_get_posts', 'my_custom_get_posts', 1 );
Please notice `7, 11, 21` in above code, these are the post IDs we are excluding from archive pages. You can specify as many comma separated post IDs as you want.

W3 Total Cache: Load CSS asynchronously for better PageSpeed score?
I'm using W3 Total Cache to minify about 15 CSS files, and also to minify 20 JS files and load those asynchronously in the footer. Running my site through PageSpeed gives me the following message:
> Eliminate render-blocking JavaScript and CSS in above-the-fold content
What I'm wondering is, how can I load this CSS file asynchronously with W3 Total Cache? The plugin doesn't give me the option to load CSS asynchronously. You can see how things are loaded on my site here. | Have much to say about both W3TC and pagespeed, but will try to stay on the point.
You should never have a JS external element in you HTML as part of the actual content, they should be either in the head element (but only scripts that must be loaded before the page finishes loading) or just before the end of the body.
CSS should be only in the head element.
The assumption is that if you decided to violate those basic performance rules you probably had a very good reason for that, and no plugin with a sane author will try to rearrange it for you as you can easily break the page if things are not being loaded in the right order.
So you need to understand first why do you have JS and/or CSS at that part of the page, and if it is not needed then you need to change your code to move them to the header or footer. Caching plugins have totally nothing to do with it and should stay away from even offering page changing functionality like that. | stackexchange-wordpress | {

Custom Post Type Fields
I am very interested in creating a coupon plugin for Wordpress, where many of the existing options do not meet my current needs. I have build the core plugin and it is working as expected now so I feel like I am getting close to accomplishing this task.
The problem is that I would like to implement custom fields into the plugin and have them easily set by the authors. These would be things like coupon code, discount amount, expiration date, etc. This plugin (coupon creator) seems to have the layout I am looking for on the Post page, but I have been unable to figure out how its done, where these do not appear to be the "Custom Fields" shown in other tutorials.
How would I go about replacing the large WYSIWIG Editor box with fields like this instead for my CPT?

$wpdb - do you have to use foreach even if there will always only be one result?
I have a $wpdb query that will always **only** return one result. This is a simplified version of it:
$results = $wpdb->get_results ( "SELECT name FROM testTable WHERE id=1" );
Do I have to use foreach to get that single result?
foreach ($results as $result ) {
$name = $result->name;
}
Or can I skip the foreach and instead do something like this:
$name = $result->name[0]; | Read the Codex:
> The `get_var` function returns a **single variable** from the database. Though only one variable is returned, the entire result of the query is cached for later use. Returns **NULL** if no result is found.
<?php $wpdb->get_var( 'query', column_offset, row_offset ); ?>
So for you its:
$name = $wpdb->get_var("SELECT name FROM testTable WHERE id=1");
If you want a row use `get_row`:
> To retrieve an entire **row** from a query, use **get_row**. The function can return the **row** as an **object** , an **associative array** , or as a **numerically indexed array**. If more than one row is returned by the query, only the specified row is returned by the function, but all rows are cached for later use.

If you need `$key` to be the value of `id`, you can also try something like this

How to leave a line between paragraphs when writing text in the visual or text editor

Category page with posts from 2 different childcategories
I have a category and will query posts from 2 different child categories see below.
This is my structure
1 category
- 1.1 category <- her we are (on this category i will show the posts from 1.1.1 and 1.1.2)
-- 1.1.1 category <- In this category are the posts
-- 1.1.2 category <- And this category are the posts
2 category
- 2.1 category
-- 2.1.1 category
-- 2.1.2 category
Thx for help. | To include posts from one or more specific categories, you can use and define category__in parameter in your WordPress query. Like this, here is an example.
$args = array(
'category__in' => array( 11, 15 ),
);
$my_query = new WP_Query( $args );
if ( $my_query->have_posts() ) :
while ( $my_query->have_posts() ) : $my_query->the_post();
get_template_part( 'content', get_post_format() );
endwhile;
endif;
wp_reset_postdata();
Where `11, 15` are the category ids of the categories that you want to include posts from. You can add as many categories as you want. You just have to add comma separated ids of those categories. | stackexchange-wordpress | {

How to hook into the CPT's title placeholder?
I want to change the default **placeholder text** in my Custom Post Type title field. This isn't possible while registering a new post type.

* @param WP_Post $post
* @return string

Backbone.js and WP API
I'm creating a theme based on the underscore theme with Backbone.js integration. I am struggling to find any clear examples/documentation on the WP-API plugin's capabilities, and starting to find it fairly frustrating.
I am pulling in a basic list of posts using the following code:
var posts = new wp.api.collections.Posts(),
posts.fetch(options).done(function(){
console.log( 'we now have 10 posts');
}
This works fine. The problem is I wish to retrieve some post_meta at the same time, without making multiple fetch calls asynchronously (one per post). There are some post_meta fields I wish to use, as well as getting the post thumbnail.
Any direction is appreciated. | Inside the PHP side of things, there is a `json_prepare_post` filter, which allows you to alter the loose `Post` object returned. Here you can attach meta data and other things, such as post thumbnails.
add_filter( 'json_prepare_post', 'eh_json_prepare_post' );
function eh_json_prepare_post( $_post ) {
$_post['post_meta']['some-value'] = get_post_meta( $_post['ID'], 'some-value', true );

WP Admin default view mode for Custom Post Type
To change it globally to `excerpt` for every post type I can use:
function my_default_posts_list_mode( $default ) {
return 'excerpt';
}
add_filter( 'default-posts-list-mode', 'my_default_posts_list_mode' );
But how can I achieve the same only for a Custom Post Type?
**Explanation:**
I've created a Custom Post Type. In WP Admin the default view mode is set to list (edit.php?post_type=my_post_type&mode=list). I want it to be `excerpt`, but **only** for my Custom Post Type not affecting other post types.
I can do this manually by adding `&mode=excerpt` to the URL like so: `edit.php?post_type=my_post_type&mode=excerpt`, however I want this to be done automatically. | To change the mode URL variable but in the load try this:
add_action( 'load-edit.php', 'my_default_posts_list_mode' );
function my_default_posts_list_mode() {
$post_type = isset( $_GET['post_type'] ) ? $_GET['post_type'] : '';
if ( $post_type && $post_type == 'my_post_type' && !isset( $_REQUEST['mode'] ) )
$_REQUEST['mode'] = 'excerpt';

Retrieve featured image as object
I want to retrieve the featured image of a post as an object (`array`) in order to have all image sizes available.
The `get_the_post_thumbnail()` function doesn't do this, any ideas? | First get the registered image sizes and the featured image attachment id:

Increasing post view count automatically
I am testing a ranking system for posts, and I'd like help with the below:
Upon publishing a new post, I'd like the post view count to immediately have a random number between 829 and 1013 added to it.
Could you please tell me how I can do that? If you offer any code, kindly let me know exactly where to put it.
Thank you. | You can automatically add a custom field to each new post on publish (on change status to publish). And then set it's value to a random number between 829 and 1013.
Here is the function that will do just that.
// Create custom field on post publish
function wpse_custom_field_on_publish( $new, $old, $post ) {
if ( $new == 'publish' && $old != 'publish' && !get_post_meta( $post->ID, 'post_views', true ) ) {
add_post_meta( $post->ID, 'post_views', rand(829, 1013), true );
}
}
add_action( 'transition_post_status', 'wpse_custom_field_on_publish', 10, 3 );
In above code, `post_views` is the name of the custom field that we are using to count post views. You should change it to yours before using it in your theme.

Adding class to featured image
I have specified a loop to show featured images for my custom post type and wish to add a img-responsive class from bootstrap to my featured image.
How can I do this?
Thanks!
Code:
<div class="home-featured-img">
<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
the_post_thumbnail(); // show featured image
}
?>
</div> | You can add custom class to post thumbnails. the_post_thumbnail accepts array of attribute `$attr` where you can specify image class.
So your code will be.
<div class="home-featured-img">
<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
the_post_thumbnail( 'full', array( 'class' => 'responsive-class' ) ); // show featured image
}
?>
</div>

How to speed up installing plugins and upgrading WordPress
I currently run on a VPS that is running the latest version of Ubuntu, PHP 5.5.9, and WP 4.0, and have been running my plugin upgrades through `libssh2` via a configuration in `wp-config.php` ever since I started working on this VPS, as WordPress is unable to open a connection automatically.
However, within the past week or so, I've noticed plugin installs and WordPress upgrades have become increasingly slow, with the browser hanging for almost 1-2 minutes before confirming that my plugin is installed. (Jetpack takes an extremely long time to update, as an example.) One side effect that I've noticed is that PHP often exits before the `.maintenance` file is removed. Problematic, as I then have to go and remove it myself by connecting to the server.
Is there a way I can speed things up and get PHP to run faster? | As you're using a VPS with SSH access, give WP-CLI a try <

Is there an action like 'after_register_custom_post_type'?
I'm writing a small plugin for Visual Composer. I need to list all custom post types but I don't know when to call the query to fetch all post types. My plugin gets initialized by `after_setup_theme`, but the function which queries the custom post types don't list custom post types, because its executed too early.
The problem: custom post types can be created within theme files (e.g. `function.php`) or plugins (like `Custom Post Type UI`).
Which action should I use to get all custom post types? I know that Advanced Custom Fields does the same (you can create custom fields for every (custom) post type), but I can't find the piece of code that does the trick. | Just as @PieterGoosen mentioned, in a deleted comment, the post types should be registered within a `init` hook callback.
The `after_setup_theme` action is fired before `init`, so that hook will not help you.

Disable site visiting and user logins excepting for a specific user
I want to disable temporarily site visiting and user logins to a multisite blog for the site maintenance time, excepting for super-admins and for a specific user.

How to list all active and specific shortcodes in wordpress
I wonder how you can list specific shortcodes, for example with this code you get a list of all active shortcode tags:

if ($shortcode_tags==[hello]) {
echo '<pre>'; print_r($shortcode_tags[hello]); echo '</pre>';
}
Any suggest; thank you | The conditional needs to test against strings which would be the name of the shortcode. If you're looking for the `[hello]` shortcode the conditional would look like:
echo '<pre>'; print_r( $shortcode_tags['hello'] ); echo '</pre>';
So if you use `add_shortcode()` the string you'll be looking for is the first parameter: `$tag`. | stackexchange-wordpress | {

Price comparison table based on Custom Post Type?
I have created a review site where clients can rate their hosting providers based on various factors, however since the launch, many have asked if it would be possible to create a price comparison table so they could look for provider's in their price range.
I believe the best way to do this will be to create a Custom Post Type and have fields for the 5-10 most common packages, where I can create a new CPT entry for each provider and set the prices there (or even give the providers access to do so themselves).
Would this be the best way to go about this with Wordpress? How can I create a page that loops through each entry for that CPT and pulls the information I need to build this table? | I suggest just making a new Post Type with the default Wordpress register_post_type().
function create_my_post_type() {
$labels = array(
'name' => __( 'Providers pricing', 'myplugin_namespace' ),
'singular_name' => __( 'Provider pricing', 'myplugin_namespace' ),
'menu_name' => __( 'Provider Pricing', 'myplugin_namespace' ),
);

'labels' => $labels,
'public' => true,
'description' => __( 'Pricing stuff for my awesome plugin', 'myplugin_namespace' ),
'show_in_menu' => true,
'supports' => array( 'title', 'thumbnail' ), // or whatever else you want from WP_Post

Disable only the comment form/box itself?
I'm trying to write a function which hides the comment form itself, while leaving comments and comment counts intact.
I'd like the comment form to display only when a certain parameter is in a post URL.
All I can find is code which disables everything comment related. And I came up with a method which would require some css (give form another ID when it needs to be hidden and then display: none;).
Does anyone happen to know of a PHP-only method? | The `comments_open()` function is used, both by core and typically themes to determine status for specific post. It has filter of same name for result, which you can use to manipulate it individually for the post.
`comment_form()` won't actually output form if check is false and fire `comment_form_comments_closed` action in such case.
