preview_post_link for Custom Post Types
I've got a custom post type, and I'd like to be able to change the preview link but from what I can tell, the hook for preview_post_link only affects the default post type.
Any guidance?
Here's what I've been trying.
add_filter( 'preview_post_link', 'append_preview_query_vars' );
function append_preview_query_vars( $link, $post ) {
if( $post->post_type === "2016program" ) {
return $link . "?program_year=2016";
} else {
return $link;
}
} | ## Two problems here:
**#1**
You're missing the `$accepted_args` argument in:
add_filter( $tag, $callback_function, $priority, $accepted_args );
Check out the Codex here for more info on that.
**#2**
Note that `$link . "?program_year=2016"` is problematic, since it gives us this kind of link:
/?p=123&preview=true?program_year=2016
But using instead `add_query_arg( [ 'program_year' => '2016' ], $link )` we get the correct form:
/?p=123&preview=true&program_year=2016
## Updated code snippet:
Please try this instead (PHP 5.4+):
add_filter( 'preview_post_link', function ( $link, \WP_Post $post )
{
return '2016program' === $post->post_type
? add_query_arg( [ 'program_year' => '2016' ], $link )
: $link;
}, 10, 2 ); // Notice the number of arguments is 2 for $link and $post
where we use `add_query_arg()` to append the extra GET parameter to the link. | stackexchange-wordpress | {

Add filter menu to admin list of posts (of custom type) to filter posts by custom field values

Check if value has changed on save_post
Writing a function to send an email to the user on save_post if a taxonomy equals a specific value. However, I only want this to happen when the value is being changed, and not on every save. Is there a way to compare if a value is being updated with a new value versus the same value it already has?
function status_save_email( $post_id ) {
if ( !wp_is_post_revision($post_id) ) {
$slug = 'sessions';
if ( $slug != $_POST['post_type'] ) { return; }
$status = get_the_terms( $post_id, 'status_tax' );
if ( $status != null ){
foreach( $status as $state ) {
$state_name = $state->name ;
}}
if ( $state_name == 'Rejected' || $state_name == 'Approved' ){
echo "bingo";
}
}
} | In the end I checked against and updated a new meta value on each save.
$screen = get_current_screen();
if ( $screen->base == 'post' && $screen->post_type == 'sessions') {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
if ( isset( $_POST['session_status_tax'] ) ) {
$status = $_POST['session_status_tax'];
} else {
$status = '';
}
$prev_term = get_post_meta( $post_id, 'prev_term', 'true' );
if ( $status === 'status-approved' && $status !== $prev_term ) {
write_post_log($post_id, 'Approved' );

Get Commentor IP When Marking Comment As Spam
What I am trying to do is create a list of IP addresses each time I click Spam on a comment. The only issue I have now is, how do I get the commentors IP address inside this function.
This is what I am working with... It ties into the onclick event of the Spam button.
add_action('transition_comment_status', 'report_spam', 1);
function report_spam($new_status){
if($new_status == 'spam'){
//do something here with IP
}
} | You are missing 2 parameters in your function `report_spam`. Also the priority should not be 1. Try the code below.
add_action('transition_comment_status', 'report_spam', 10, 3);
function report_spam($new_status, $old_status, $comment){
if($new_status == 'spam'){
var_dump($comment->comment_author_IP);
die;
}
}

Filter user list that meta_value is empty

)
)
)
);

Cloning admin pages like users.php
In my project I want to make a new menu position which will be actually a copy of 'Users' page but with some additional filters/modifications. For example as a result I need to have another menu position above users called "Admins" which will show exactly same structured page but with only Admin users. It is for better/easier user experience for my client.
My question is how to do this? I know that there are functions like `add_menu_page` but using them like this (`users.php` as identifier):
add_menu_page( 'custom menu title', 'custom menu', 'users.php', 'myplugin/myplugin-admin.php', '', plugins_url( 'myplugin/images/icon.png' ), 6 );
results in two menu positions which collapse and expand together, and I wanted them to work independently. I can also show content based on function but I don't know if there is any way to easily output content of whole users.php page? | After some further research I have used WP_List_Table class for this. I had to add buttons and links myself to make it look like users.php but it wasn't much of work. | stackexchange-wordpress | {

Using Cookie Data For WP_Query Loop
I'm trying to retrieve data set in a cookie and use this to run a query.

$cookie_array = $_COOKIE["your-results"];
// Test output
echo $cookie_array;
$sug_args = array(
'post_type' => 'product',
'post__in' => array( $cookie_array )

How does WordPress Multisite know that a Plugin is installed?
I am running a WP Multisite Network.
I am curious to know how WordPress knows that a plugin is installed on a network site:
* how does WP know that a plugin is Network Activated?
* how does WP know that a plugin is activated at the site level?
Does it record this instance in a DB Table somewhere? If so, which table and how is it tagged?
Thanks for helping. | You can clearly see the way WordPress loads plugins if you inspect the source code of the file `wp-settings.php`.
The function `wp_get_active_and_valid_plugins()` loads plugins for individual sites in the network and for non-Multi-Site installations, while `wp_get_active_network_plugins()` loads network activated plugins when Multi-Site is enabled.
The former more or less just calls get_option() to get the `active_plugins` option from the wp_options database table, while the latter uses get_site_option() which is the network-wide version of `get_option()`. The option which has the network enabled plugins is called `active_sitewide_plugins`. | stackexchange-wordpress | {

Display page contain in index.php file
I use following code to display page in a index.php file of template but doesn't show page content.
<?php
$parent_page_content = get_the_content(1677);///my_page_id
echo $parent_page_content;
?> | get_the_content( $more_link_text, $stripteaser )
`get_the_content` does not take a post ID as a parameter, it always refers to the current post.
Also, don't use magic numbers or hardcode post IDs into your theme, it will break after an import/export or migration.
Instead use `get_page_by_title`, which is not as bad:
// get the post
$post = get_page_by_title('page or post title', OBJECT, 'post' );
// filter its content
$content = apply_filter('the_content', $post->post_content );
// display it
echo $content; | stackexchange-wordpress | {

Facebook / LinkedIn share page - https opengraph issues
I have added the Open Graph meta data to my **functions.php** :
function insert_fb_in_head() {
global $post;
if ( !is_singular())
return;
echo '<meta property="fb:admins" content="PAGE_ID"/>';
echo '<meta property="og:title" content="' . get_the_title() . '"/>';
echo '<meta property="og:type" content="article"/>';
echo '<meta property="og:url" content="' . get_permalink() . '"/>';
echo '<meta property="og:site_name" content="SITE_TITLE"/>';
echo '<meta property="og:image" content="' . $default_image . '"/>';
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );
However when pasting from HTTPS, it does not fetch the OG data. Sharing from HTTP works perfectly fine.
I also tried adding:
og:image:secure_url
Didn't work either.
!HTTP vs HTTPS LinkedIn Share | I used the Open Graph Debugger: <
Result:
Inferred Property The... property should be explicitly provided, even if a value can be inferred from other tags.
So all I had to do:
<meta property="og:..." content="
<meta property="og:..." content=" />
That extra space between **" />** was the fix. Weird.
Also remember LinkedIn caches the data for **7 days** , so check later on the week if fully resolved. | stackexchange-wordpress | {

Updating plugins asks for FTP information, why? (this is a new one)
First off, this has nothing to do with permissions, I already checked that. So please don't mark this as a duplicate.
Any time I try to update a plugin, I get this dialog:
!enter image description here
I went overboard and allowed all permissions (-rw-rw-rw-) on all files, and _still_ the plugins won't update without FTP. And SFTP is not an option, as I'm using ssh keys on this server (no passwords allowed). I'm running WP on nginx and php5-fpm. What else should I try to do? | Figured it out. Apparently WordPress is a bit dumb, and even if your files are owned by user `abc` and group `www-data` (`abc:www-data`) and are all group-writable, WordPress still won't do the easy update method unless the files are actually owned by `www-data:www-data`. It doesn't even bother checking the group permissions. | stackexchange-wordpress | {

How can you change default color scheme in a Twenty Fifteen child theme?

$schemes['maroon'] = array(
'label' => __( 'Maroon', 'twentyfifteen' ),

'#C32148',
'#ffffff',
'#333333',
'#333333',
'#f7f7f7',
),
);
return $schemes;
}

Change WordPress Resource URL
I have recently finished developing my latest WordPress theme for my own site and as usual I was going to use maxcdn and w3tc to make it faster!
However my Hosting company have started up their own cdn service and I have got 3 months free to test it out! However it is not as easy to set up as Maxcdn and have been told that I need to change the resource url to use cdn url and serve my images, css and js files.
I have added all my css and js files in my function.php file like so...
wp_enqueue_style('BrumWebEngineer-style', get_stylesheet_uri());
wp_enqueue_style('BrumWebEngineer-core', get_template_directory_uri() . '/css/core.css');
Naturally I cannot replace the get_template_diretory_uri with the cdn url so am wondering how I can go about this.
Many thanks. | To dinamically change the stylesheet and template URI you can use `stylesheet_uri` filter and `template_directory_uri` filter.
For example:
add_filter( 'stylesheet_uri', function( $stylesheet_uri ) {
$stylesheet_uri = 'your new stylesheet URI here';
return $stylesheet_uri;
} );
But, as you are using W3TC, you can configure that change in the plugin itself (Generic Mirror and Self-hosted CDN options), even you can configure pushing files automatically if the CDN service support it. | stackexchange-wordpress | {

Are all hooks/functions tied to Kses meant for sanitization?
I'm currently learning WordPress hooks and am delving into core to see what's happening in there. I noticed there are filters in wp-includes/default-filters.php with PHP comments about Kses. I wasn't sure what Kses meant until I found wp_kses in the Codex.
The notes on this page says:
> KSES is a recursive acronym which stands for “KSES Strips Evil Scripts".
So then do I assume anything I find in core with either kses in the code or the PHP comments has to do with data sanitization? Just trying to understand general patterns in WordPress core. Thanks! :-) | > ... anything I find in core with either kses in the code or the PHP comments has to do with data sanitization?
It would have to do with the functions that sanitize data or with data that needs to be sanitized, yes. That is the primary reason for the KSES code, which, if you look it over, is pretty resource intensive. You wouldn't want to use it unnecessarily. | stackexchange-wordpress | {

customize taxonomy Page
is there a solution to customize taxonomy page and make it like categories page with a Title h1 and customize Sidebar?
this is my taxonomy code :
register_taxonomy('director', 'post', array(
'hierarchical' => false, 'label' => 'Realisateur',
'query_var' => true, 'rewrite' => $rewrite2)); | This depends on how your theme handles Taxonomy pages. If it e.g. has a `category.php` that does stuff different than `taxonomy.php` or `archive.php` this is the reason.

Modifying lightbox plugin to allow for quoting, Does this exist?
I've been searching online for a plugin to use with my website that would allow the the user to click on an image in a foogallery image gallery and then have the image open in a fullscreen lightbox.
This itself is easy enough, but I would also like the user to be able to be able to click a toggle button and have a quote form that once filled and submitted would be sent to my email appear in the bottom third of the page.

Display Taxonomies in loop with template args
I want to display the taxonomies within the loop but with customized template.

the_post();
$args = array(
'template' => '%s %l',
'term_template' => '%2$s',

the_taxonomies($args);

"Kategorien **Neues** und **Zweite** "

" **Neues** , **Zweite** "
without the string "Kategorien" and another seperator "und"?

Following your way:
Change your `$args` like so:

'template' => '%2$l',
'term_template' => '%2$s',
);

// $templates['between_last_two'] = sprintf( __('%s, and %s'), '', '' );

why update option is not working?

thanks | update_option('acp_cf_settings' , array('acp_cf_status'=>$resp['status']));
update_option('acp_cf_settings' , array('acp_cf_log'=>$resp['log']));
You are overwriting the setting. After the second `update_option` call there is no `acp_cf_status` key anymore for the array variable, just the `acp_cf_log`.
Just to be clear, you would need something like this:
update_option( 'acp_cf_settings', array(
'acp_cf_status' => $resp['status'],
'acp_cf_log' => $resp['log'],
) ); | stackexchange-wordpress | {

early enqueueing javascript file in page template, not in functions.php
Is it at all possible to enqueue javascript file early on page template file?

I don't want to change functions.php. I only want to modify template file. I can enqueue the script no problem, but it is always added at the end of the page, and I need this script to be available upfront (before some of the HTML is displayed - preferrably before ANY of the HTML is displayed). | Short Answer: Yes, but...
Just make sure your call to `wp enqueue script` is before the call to `get_header()`. The problem is that when you're in a later part of your template the header including the script is already sent to the browser so you can't change it any more.
While this is possible I'd still encourage you to reconsider and put this in the `functions.php` or a simple plugin. Enqueueing scripts is application logic and therefore shouldn't be in a template. | stackexchange-wordpress | {

function alter_category_link($termlink) {
return 'abcdefg';

Why user_pass column in wp_users table is varchar(64)
while working on a project, I found that "user_pass" column in "wp_users" table is varchar(64). WordPress always stores user password in md5 which is a 32 char ASCII string. So why not store it in char(32) with ascii collation. I am asking because I am working on a table that stores user password. Is there any other advantage of using varchar(64). | It is because of different encrypted algorithm. Sometimes users will override the MD5, which is the default algorithm, and add their own, which might need a little longer length to store the password.

further if you just want the container to widen and not the header, footer et al. then just add this css
.container {max-width:1170px!important;}

WP-Admin gives 403 Forbidden after login on CentOS 7
I've setup a brand new CentOS 7 VPS; everything configured by me. LAMP installation and the Apache virtual host configurations are all done. I've checked them before installing Wordpress and the HTML sites were being showed as well as the PHP info and everything else.

How to intercept a 404 error
I'd like to intercept 404 errors and do some things before to show the 404 error page.

}
}
add_action( 'template_redirect', 'wpd_do_stuff_on_404' );
Refer to the Action Reference for the general order of actions on the front end. The main query runs between the `posts_selection` and `wp` actions, so that is the earliest you can determine that a request is a 404. The template is then loaded after `template_redirect`, so it's too late to set headers after that point. | stackexchange-wordpress | {

I want to use this: < on a website but it seems to need those attributes and it won't work if I have to manually add them to each image for every blog post. | Yes you can. See my working fiddle here:
<
1. You need to add an id.
example: `<img class="img" id="imageid".....`
2. Delete all atribute "data-width" and "data-height". because it will added automatically.
3. Add this javascript:
(you may change the '$' to 'jQuery' if doesn't work with your theme)
<script> var img = document.getElementById('imageid'); var width = img.naturalWidth; var height = img.naturalHeight;
$( document ).ready(function() {
$('div.aspectRatioPlaceholder').find('*').attr('data-width', width);
$('div.aspectRatioPlaceholder').find('*').attr('data-height', height); }); </script>
Better is using javascript like example above. But if you want to process with php. you can modify your themes/plugin using this:
<?php list($width, $height) = getimagesize("image URL here"); ?>
it will produce $width as real image width, $height as real image height.

X-Axis of Site is Messed Up Because it is in Hebrew
One of my client's sites are in Hebrew which is a right-to-left language.
I'm using the MH Newsdesk Lite theme found on wordpress.org . The theme is using a **core** wordpress generated class `.screen-reader-text{}` to display the search form with `get_search_form()`.

Check this(Line # 314 style.css):

Control what custom posts a user can see
I've been looking into user roles and it would seem that there are 100 plugins to help me control what a user can edit or publish but they don't get any more specific.
We have a custom post type called Chapters and we have hundreds of users who can view said Chapters. What we want to do is add a new user role that can only view certain posts within the Chapters post type. So we have 51 Chapters and we only want the new role to see 31 of the 51 chapters.
EDIT: I'm talking about the front-end. Our site requires subscription to access it so the new user role would be a like a subscriber, only they couldn't see specific "Chapters" | Using plugins like Paid Memberships PRO or s2member would be easiest solution for your purpose.

How to order posts by meta value?

$paged = get_query_var( 'page' );

'cat' => $category_id ,
'meta_key' => 'deadline' ,
'orderby' => 'meta_value' ,
'order' => 'DESC'
));
get_template_part( 'loop' );
but it doesn't work to order posts by `meta_value`. | As mentioned above, never use `query_posts`, as it breaks a lot of stuff. Use a filter like `pre_get_posts` instead.

Permalinks stopped working - NO update, mod_rewrite enabled, .htaccess not touched

Blank spaces show as a question mark
I have a client who wanted to restore her old website from 5 years ago with a very small budget.

Now, all extra blank spaces that were in the text show up as question marks inside a black diamond. They show as proper blank spaces in Wordpress editor, and in PHPmyAdmin. Our old pages all have UTF-8 encoding.

Override static home page post
In functions.php is it possible to dynamically set the static home page?
The condition could be anything, but for example by domain:
if ( $_SERVER['HTTP_HOST'] == 'domain-one.com' )
set_front_page_slug('domain-one-home');
else if ( $_SERVER['HTTP_HOST'] == 'domain-two.com' )
set_front_page_slug('domain-two-home');
Note that it should not permanently change the home page set in the WordPress Settings, only for the current page load. I want different visitors to see different homepages.
Any approach welcome that can neatly override the default home page. | This is the best solution I've been able to come up with, and satisfies the need to dynamically set the home page (not template) based on factors such as subdomain.
add_action( 'pre_get_posts', 'dynamic_home' );
function dynamic_home( $query ) {
if ( is_front_page() && $query->is_main_query() ) {
$query->set( 'post_type' , 'my-cpt' );
$query->set( 'name' , 'a-slug' );
$query->set( 'p' , null );
$query->set( 'page_id' , null );
}
}
In the above some_custom_condition() could contain logic such as if the current URL is the home page.
This example overrides the home page with a custom post type, but could be simpler if just page content types were used.
Setting the template alone is not sufficient and does not scale to potentially unlimited number of home pages. Such a scenario would be each user of a site having their own personalised home page on their own subdomain. | stackexchange-wordpress | {

the_permalink displays post ID URL for future posts
I use a WP template to generate an email newsletter. I display future posts and until recently using the_permalink displayed the full human-readable URL (e.g. /this-is-a-page). Now it displays the post ID URL (e.g. ?p=5800). How do I get WP to display the human-readable URL?
More strange, perhaps, on the Add/Edit page for my future entries, when I add or update a story to be published in the future, the message up top "Post updated.

Reliable method to detect mobiles
I'm running a WordPress site and wanna setup a mobile site based on it.

if(is_mobile()) {
// mobile theme code
} else {
// main theme code
}

wp-config.php being deleted
I am helping someone sort out a site, it suddenly wanted to be installed instead of showing the site itself. I found that the wp-config.php file was missing.
Fortunately there was a backup and I restored the wp-config, about a week later it was deleted again.
This time I extracted the backup zip file to a directory so it would be easily available, copied the wp-config and got the site working.
Today the wp-config has disappeared again. But a 'smoking gun' is that the wp-config file in the backup directory has also gone. (yes, I still have the zip).
I suspect there is a plugin on the rampage targetting that file name. I have suggested a fresh install and reinstall all the plugins, it might come to that.

Taxonomy terms sort by... Last name!

* Elena Blue
* Daniel Green
* Andrea Red
Do you have any advice to do it? Is it better to add a New Custom Field in Custom Taoxnomy where I specify the Last Name and then I sort by that term?

Elena | You can try the MySQL function `SUBSTRING_INDEX()` within the `get_terms_orderby` filter:

* @link

{
if( isset( $args['orderby'] ) && 'wpse_last_word' === $args['orderby'] )
$orderby = " SUBSTRING_INDEX( t.name, ' ', -1 ) ";
return $orderby;
}, 10, 2 );
to order by the _last word_ in the _term name_.
Here we activate the _last-word_ ordering through our custom `wpse_last_word` argument:
$terms = get_terms( 'category', [ 'orderby' => 'wpse_last_word' ] );

Permalinks - .htaccess
According to the official WordPress docs, when you save your Permalinks it updates your .htaccess file (<

Can someone clarify if the WordPress docs are inaccurate or if there's something I'm missing. | > According to the official WordPress docs, when you save your Permalinks it updates your .htaccess file ...
This isn't correct. When you switch from default-- `?=` permalinks which are nothing but pure PHP URL parameter passing-- to anything else then WordPress will create a `.htaccess` file if it can, or tell you to create one. Once that file is created the permalinks are generated entirely internally to WordPress. The `.htaccess` file does not need to be, and isn't, updated every time you change permalinks. You can see the `file_exists()` check in the `save_mod_rewrite_rules()` function.
Specifically, what happens in that WordPress creates a `.htaccess` file telling the Apache to send all requests to the `index` page thus allowing WordPress to take over. | stackexchange-wordpress | {

I need to have 8 separate post meta fields on each post in wp-admin (shown in a custom meta field box).
I'd like the data from these 8 fields to be stored in an array as one post_meta field for easy parsing on the front-end.
What's the best way to do this? I have found examples of how to do this via PHP, but not how to combine inputs in the backend on save. | I agree with kraftner's comments to the question. This is a bad idea and you stand a good chance of regretting it later. Store you data as granular post meta values. Everything is easier later on.
However, `add_post_meta()` and `save_post_meta()` will serialize objects/arrays for you. You don't have to do anything special:
update_post_meta(1,'my_bad_idea',array('i','will','regret','this','later'));
And `get_post_meta()` will unserialize it for you:

Using Customizer value in an external PHP file inside a theme
I'm working on a theme for a company and they don't want the users to touch the code at all. So as I love, they asked me to use Customizer API.
Now, there's a PHP file in the theme which we don't call anyone but on a MailChimp form, via AJAX. So basically, this PHP file is inside /inc/helper/mailchimp.php file but only gets called by an AJAX script.
So is there any way to render Customizer value inside the form? And the value will MailChimp API key so we don't want this to appear anywhere in the source code.

WordPress admin menu formatting issue
I'm having an issue with my admin menu in WordPress. As you can see in the image below the formatting of the menu is out of order. This happens whenever I first land on one of the admin pages but if I refresh the page the menu looks fine. I tried disabling my plugins but none of them seem to be causing the issue.
![WordPress admin menu]( | Otto has suggested a fix in Chrome itself until the bug is resolved:
* Go to chrome://flags/#disable-slimming-paint
* Enable the "Disable slimming paint" option.
* Ensure that the "Enable slimming paint" option below it is not turned on.
* Relaunch Chrome.
If you don't want to take this approach you can fix this with CSS:
function chromefix_inline_css()
{
wp_add_inline_style( 'wp-admin', '#adminmenu { transform: translateZ(0); }' );

How are roles stored in the database?
I know roles are defined < but how are they stored in the database? For instance, how is "Super Admin" stored i.e. 'super_admin'? | The core functions:
* `is_super_admin()`,
* `grant_super_admin()`,
* `revoke_super_admin()`

$super_admins = get_site_option( 'site_admins', array( 'admin' ) );
It's stored as a serialized array of user logins, for each site, like:
a:1:{i:0;s:6:"louiev";}
It's possible to override it with the global `$site_admins` array.
On the other hand, the general user roles ( _admin_ , _editor_ , _author_ , ...) are stored as serialized arrays, for each user, like:
a:1:{s:13:"administrator";b:1;}
in the `wp_usermeta` table under the `wp_capabilities` meta key and/or the `wp_{$blog_id}_capabilities` meta keys.

In short, How can I get the child categories for `taxonomy=portfolio_category&tag_ID=80&post_type=portfolio`? | Use `get_terms()` to get the child terms of a given term. You need to feed the specific term id to either
> * **`parent`**

## EXAMPLE:
Get all descendants of term ID 80

Structure of postmeta meta_value for woocommerce product download
So I'm working on a monster script to port all of our existing stuff from Joomla/Virtuemart to Wordpress/WooCommerce.
So far I've got just about everything done with moving over our product categories and products, I just need to figure out the structure of the `_downloadable_files` postmeta.

a:1:{s:32:"ded830cf64e3c42c4f7ac5aecd7c5c86";a:2:{s:4:"name";s:0:"";s:4:"file";s:114:"
How is the `s:114` just before the file url generated? That is the only part that changes that I don't know how to generate.
Any suggestions would be greatly appreciated! | In short, this is serialized data and this is how data is stored from a custom field (and many other datastrings) in the db.
`s:114` is auto generated and simply means that the value ` is a string and is 114 characters long. This is used when the data is read and used. If the URL value changes, the string length will change as the length of the string changes

Manually Create PHP Page For A Redirect
I am new to wordpress and working on something for a friend, I have FTP access, and am trying to upload a php file, that checks the platform and redirects the user either to the iTunes store if they are on an iOS device or force downloads a file if the user is on any other platform.

WooCommerce - Create Products Programatically
I'm writing a plugin that will automatically import products via JSON API. I need to programatically create/update products.
I did a research and it seems everyone is using `wp_insert_post()` and `update_post_meta()` for this, ie this and this
However, I found that there's the `class-wc-api-products`, where are various functions for adding/editing products and variations.
Is there any reason why people don't use something like:
$wc = new WC_API_Products();
$wc->create_product( $data );
It seems to me more future-proof to use native WC classes for this, am I wrong? | Technically speaking, Woocommerce products are just another WordPress post object with a customized post type (which is `product` in this case). If you take a look at the `create_product` function inside `class-wc-api-products.php`, you'll see this line:
// Attempts to create the new product
$id = wp_insert_post( $new_product, true );
So the API ends up using `wp_insert_post` eventually. I guess you can do both but it's obviously using what WooCommerce API provides to create a WooCommerce product is a better way to go. | stackexchange-wordpress | {

How can i make WP_Query return post image and categories?
I have a sidebar widget that will display related posts based on a custom meta field. The query works, but its very wasteful.

To best explain the data i want ill use an sql query that would give me the data i want. I know the database isnt structured this way its just for an example.
SELECT title,image,category FROM posts WHERE nb_gameids_key = 14 ORDER BY datecreated LIMIT 6 | You don't need to worry to much about your query as there is not much you can do about it. You can unfortunately not just only query categies, post titles and images natively using `WP_Query`. Post categories needs to be called separately inside the loop, just like featured images.
If you dig deeper into core, you will see that all postdata and post terms are cached, so when you think you are making extra db calls, you are not. The cache is first checked for the requires data, if it is, the data is retrieved from the cache, otherwise the db is queried and the data is cached for later queries.
You can add `'no_found_rows' => true,` to your arguments if you are not going to paginate your query. This makes the query faster as it ignores pagination. Alternatively, you can use `get_posts` which has this already build in
Also, you can make use of transients to store the result from a query and only flush the transient when a new post is added in a particular category or custom field | stackexchange-wordpress | {

I'm new at CSS, so hopefully I'm close. | Did you try
.post-156 h1{
color: #666666 !important;
}
If one of your wrapper elements, like `<article>` is unsing `post_class()` the post ID becomes a class of this wrapper like `.post-156`. So you can say all h1 which are contained in a wrapper with the class `.post-156`
Another possibility, if your `<body>`-Tag is using `body_class()`:
.postid-156 h1{
color: #666666 !important;
}
