How do I create a secondary version of the_content
I am trying to create a secondary/alternate version of the_content with some changes. This is the code I found to start with:-
function new_content($content) {
$content = str_replace('<img','<img class="newImgclass"', $content);
$content = str_replace('<p>','<p class="newPclass">', $content);
return $content;
}
add_filter('the_content','new_content');
I want a version of `new_content` that doesn't affect the original `the_content` that is when I echo new_content only, all the `p` have a `class="newPclass"`. Right now, the changes are being applied to the_content. | You're overcomplicating things. If you want `the_content()` to behave as it usually does, then don't change it via filter or similar.
Just create your new custom function, eg like so (could be placed in your functions.php or if you're in a plugin somewhere there)
function replaced_content() {
$content = get_the_content();
// $content = str_replace ...
print $content;
}
Then you can use it just like any other function
<div class="main-content"><?php the_content(); ?></div>
<div class="another-content"><?php replaced_content(); ?></div> | stackexchange-wordpress | {

Can I link to content dynamically from a page to a new page?
I am new to Wordpress dev, and I have a page that loops through some custom fields(repeater) of people.
I'd like each subfield link to go to another page that has more info from that person on the previous page(same field group data). Is there a dynamic way to do this or do I need to create a new page for each person to show more details on link click? | I solved this by using this as my link, then doing a check on name to show the correct data in the new template:
<a class="btn" href="<?php echo esc_url( add_query_arg( 'n', $name, site_url( '/person-info/' ) ) )?>">Read more</a>
And updating functions.php:
function add_custom_query_var( $vars ){
$vars[] = "n";
return $vars;
}

How to set a user meta key value based on another user meta key value
Each of the 7,000+ users on my site has around 25 keys in the usermeta table. I won't list them all, but two of the keys are "access_code" and "association".
There are several dozen unique access codes for my site and each user is assigned only one access code.
Here's what I'm trying to do: I want to find all the users with the access_code key with value "abc" and for each of those users where that value is true, their association key would change to "XYZ Corporation".
Any thoughts? | You would need to use a meta query for this.
$meta_query_args = array(
array(
'key' => 'access_code',
'value' => 'abc',
'compare' => '='
)
);
$args = array(
'meta_query' => $meta_query_args
);
$users = get_users( $args );
// User Loop
foreach ( $users as $user ) {
update_user_meta( $user->ID, 'association', 'XYZ Corporation');

Do I need to use wp_reset_postdata for my function?
I am using this function which seems to work fine, however I was wondering if I must use `wp_reset_postdata` after `endwhile`?
function evecal_task_function() {
$args=array(
'posts_per_page' => -1,
'post_type' => 'events'
);
$now = time();
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) :
while ( $the_query->have_posts() ) : $the_query->the_post();
$fxdate = strtotime(get_field('fl_date',false,false));$datediff = $now - $fxdate;
if ( $datediff > 1) {update_field('fl_expire', '1', get_the_ID());}
endwhile;
endif;
} | Yes you should, otherwise you could interfere with another query happening on the same page.
Using `$the_query->the_post();` interferes with the global `$post` variable, and `wp_reset_postdata()` serves that exact purpose, to reset the global `$post` variable to the original (global) query. _Read more_ | stackexchange-wordpress | {

Prevent WordPress plugin from connecting to its server

How can I resolve the php notice "Constant EMPTY_TRASH_DAYS already defined"
With `define('WP_DEBUG', true);` in wp-config.php, I get the following notice:
> Constant EMPTY_TRASH_DAYS already defined in /wp-config.php on line 83
I have checked this file, and this constant is defined just once. I've also searched through all of the php files on the server and don't see that it's defined anywhere else. I've run a thorough search. The only other place it's defined is in `default-constants.php`:
> if ( !defined( 'EMPTY_TRASH_DAYS' ) )
> define( 'EMPTY_TRASH_DAYS', 30 );
By commenting out the second line, the notice disappears. But it doesn't make sense to have to edit `default-constants.php` in order to define the constant in the proper place, which is `wp-config.php`.
How should I define this constant properly, without editing `default-constants.php`, which risks being overwritten during an upgrade? | When defining any WordPress constants in wp-config.php you need to do it before this line:
require_once( ABSPATH . 'wp-settings.php' );
That line loads many of WordPress’s default constants, and if you haven’t already defined them yourself then they’ll be defined in that line, meaning that any of them that you try to define after this line will have already been defined. | stackexchange-wordpress | {

UnInstallation of a Plugin from a developers perspective - The correct and clean method
I think a good developer should provide the uninstallation in the safest and cleanest possible way.
I downloaded various plugins today to understand the process, but everything was very confusing. I found that many plugins are using both uninstall.php files and `register_uninstall_hook(__FILE__, 'pluginprefix_function_to_run');`
Is it correct?
because the link that I have provided above says that these two are two different methods. so what is correct using either registration hook or uninstall.php or both? | They’re just two different ways of doing the same thing. It’s up to you which one to use, or whether to use both. Neither is ‘correct’. Use whichever makes more sense to you with the structure of your plugin. | stackexchange-wordpress | {

Add attribute only to first image of every post via functions.php
I would like to use a simple function in order to add a specific attribute (lets call it “example”) to the first image of every blog post, so that I don't have to do it manually in thousands of posts.
Unfortunately I'm not very good with preg_replace so any help will be appreciated. | add_filter( 'the_content', 'wpse317670_add_img_attribute' );

$from = '/'.preg_quote('<img', '/').'/';
$to = '<img example="example"';
return preg_replace($from, $to, $content, 1);
}
This will add the `example="example"` to the first image found in every post content.
There is another option, without using regular expression (possibly much faster and will use less memory):
add_filter( 'the_content', 'wpse317670_add_img_attribute' );
function wpse317670_add_img_attribute( $content ) {
$from = '<img';
$to = '<img example="example"';
$pos = strpos( $content, $from );
if ( $pos !== false ) {
return substr_replace( $content, $to, $pos, strlen( $from ) );

Including a Customized Initialize File with a wordpress header
We began this project without using wordpress, and have a significant amount of code related to user and access control that we would like included on CERTAIN pages in the site (namely the shop). We are using woocommerce as our cart, and we need to have the ability to connect our existing database of users to the site so that non employees can still use the front end while the shop that we want to create using woocommerce will only be accessible to people who have an account on the employee portal. The Directory for all the non-wordpress is in a folder below wordpress, or in other words, wordpress is at the root, and our project is in a directory below the root. | It's not clear where you need to add this additional code. But I would assume that it is in 'include'-type files that you need to run in the portion of the generated page.
So, to do that, use the `add_action('wp_head','your-function-name')` to load your external function file:
add_action('wp_head','include_my_include');
function include_my_include() {
include get_template_directory() . 'your-function-file.php';
return;
}
See here: < .

How do I rewrite a single category link to point to a custom page?
I have categories Cats, Dogs and Rabbits.
I would like to change the link used for "dogs" when listing category on the front end to a custom page instead of the category archive. | Your goal seems to be to change the link which is output when listing the categories rather than making the existing link point to a different page as my last answer assumed. So I am going to try a different answer with a different solution.
Using the filter `term_link` in the function `get_term_link()` you can change the link which is generated for a specific category.
function wpse_317747_filter_term_link( $termlink, $term, $taxonomy ) {
if ( "category" !== $taxonomy || "dogs" !== $term->slug ) {
return $termlink;
}
return get_permalink( $target_page_id );
}
add_filter( "term_link", "wpse_317747_filter_term_link", 10, 3 );
This changes the generated link if working on `category` taxonomy and the current term slug is `dogs`. Just set `$target_page_id` to correspond to the page you want the link to point to. | stackexchange-wordpress | {

Multisite on single wordpress
I've got single site on instance of wordpress. Now I want to add second blog so second site (separate domain) under the same hosting so the same wordpress instance.
Is it possible to achieve it having sweparate not related domains? I'm new in wordpress area and most of tutorials I saw are about multidomain with having subdomain or subdirectories so not my case. | You absolutely can have a single WordPress Multisite installation serve up more than one domain.
1. Set up Multisite. For this site, it won't matter if you use subdirectory or subdomain. (If you plan to add other sites to this Multisite network, choose the option you'd prefer to use for those other sites.)
2. Create your new site.
3. Go to the new site's Dashboard, and mouse over its name in the admin bar at the top of the page. Select **Edit Site** from the dropdown menu.
4. Change the **Site Address (URL)** to what you want it to be, and save the changes.
**Note:** You'll need to make sure that your new domain name is registered, and that its DNS entry points to the appropriate IP address. You'll also need to make sure that your WordPress server's configuration is set to accept requests for the new domain name. This is something you'll either need to handle yourself, or take up with your hosting provider. | stackexchange-wordpress | {

In modifying a file in a subfolder in a child theme, do I need all the files in that sub folder in my child?
I am working with a Child theme and I needed to change a page in a subfolder in the theme. I uploaded the entire folder with all the enclosed files and modified the one file which worked. My question is... do I need all the files in the subfolder or just the one I modified? | No, you _should_ only need the files that you are going to modify.
Technically you can move all the files from the parent-theme into the child-them. When you move only the files which need changing into the child-theme then it's a little simpler to keep track of the changes.
Also good to know when working with child-themes: `get_template_directory_uri()` will always grab the path to the parent theme. & `get_stylesheet_directory_uri()` will always point to the path of the active theme (whether it's parent or child) | stackexchange-wordpress | {

How to test another theme in a live WordPress website instead of live preview?

* Using plugin: A plugin named WP-Staging may help you the manual process.

another question why when I perform have_posts() inside page.php the return value is 'true'? shouldn't it contain no posts at all in this page? | The wording is (for historical reasons) a bit confusing. Actually Post can mean two things in WordPress:
1. The literal Post as in Blog-Post
2. A general term encompassing other default Post Types (like e.g. Pages) or Custom Post Types.
So there is the Post Type "post" just like there is the Post Type "page".

Display Custom Post Type in divs
I'm sorry if this is a already asked Question but i'm trying to get my custom post types displayed in grid like this:
<div class="row>
<div class="col-md-4>
/* Start the Loop */
while (have_posts()) : the_post();
get_template_part('template-parts/post/content', get_post_format());
endwhile; // End of the loop.
</div>
</div
that mean i would like to Display every post in a div with the class col-md-4 | You'll want to move the row/columns inside the loop to do this. Perhaps even inside the template part. Seeing as I don't know what's in there, I'd suggest this: (notice I corrected your missing " at the end of div classes and added php start/stop)
<div class="row">
<?php
/* Start the Loop */
while (have_posts()) : the_post();
echo '<div class="col-md-4">';
get_template_part('template-parts/post/content', get_post_format());
echo '</div>';
endwhile; // End of the loop.
?>
</div>
this is fine if there are only 4 items in your row. or your system handles row calculations for you. If it doesn't you'll need to move the row call into the loop as well and add item count and then if statements for the 1st and every 4th item after that. | stackexchange-wordpress | {

Link works although page was moved to another location
I am a new to WordPress. Please help me with the following issue.
I created page A and set Parent to X, hence its permalink was displayed as "<
In page B, I reference to page A by the attaching the link "< there
I then changed Parent of page A from X to Y. The permalink of A thus was updated as: "<
I visit page B again and click on link "< it still works and brings me to link "<
I wonder how it could happen? I was expecting to see Page Not Found or something like that as link "< is no longer available.
There probably is something I don't know about how the link in WordPress works. Can somebody please help explain this to me? Thanks! | ## That is called _canonical redirect_.
And it's done through `redirect_canonical()` which basically
> Redirects incoming links to the _proper URL_ based on the site url.
and
> Will also _attempt to find the correct link_ when a user enters a URL that does not exist based on _exact_ WordPress query.
(Those excerpts were both taken from the function's reference.)
So in your case, although the post parent of `A` has changed from `X` to `Y`, the post `A` (or a post with that slug) still exists, and therefore, when you visit the old URL:
(old URL - post parent is X)
with canonical redirect, you'd be redirected to the correct URL:
(new URL - post parent is Y)
and not being presented with a `404` (page not found) error page.
Try visiting ` and you'd see the canonical redirect being applied.
And if you visit ` assuming there are no post with `A123z` as the slug, then you'd see the 404 error page. | stackexchange-wordpress | {

Simply deleting XMLRPC file
I have never used XMLRPC for any activity for my WordPress sites and also not going to do so.
There are many articles on disabling XMLRPC on your site for additional security.

How to disable a jQuery plugin on WordPress plugin page
I have created a WordPress search plugin for a customer. It worked at my site, but when I installed it in my customer's website it broke, because there is a `jquery.formstyller` plugin installed there, which apparently styled the dropdown I used in the plugin with it's own divs and styles.

How to disallow a certain custom gutenberg block outside of an InnerBlocks block?
I did add a custom block as an `InnerBlocks` block, called `slider`. Then i got another custom block `slider-item`. I think you get the idea.
The slider block just allows `slider-item` as it's child blocks. Like so:
<InnerBlocks
allowedBlocks={ [ 'ajk/slider-item' ] }
template={[
[ 'ajk/slider-item' ],
[ 'ajk/slider-item' ],
]}
/>

Or is there some kind of **repeater block** possibility i do miss?!

WP `4.9.8`
Gutenberg `4.2.0` | In the `slider-item` you can specify **parent** must be `slider`. That way, the `slider-item` cannot be used outside of your `slider` container block.

Font Awesome icons disappearing

Difference between these two nginx try_files statements for WordPress?

You're not actually specifying it. You're trying to use it in your regex and THEN you specified it.
You can't use it in your "if" criteria when if it doesn't exist. You need to check to see if it exists first.
The following would set your value if it is not set OR if it IS set and doesn't match your regex:
$options = get_option( 'analytics' );
if ( ! isset( $options['analytics_startdate'] ) || ! preg_match( '/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/', $options['analytics_startdate'] ) ) {

Images do not show in the website, but they appear on new tab

However, after I updated it, my images do not appear on my website anymore. The pages only shows white blank space where the images should be. I can open the images on new tabs without any problem.
I suspect that the problem lays on the theme setting, because when I changed to the other theme, it worked.
I want to keep my current theme for my website. Where can I check the code to get the images? | You will need to learn about the Template Hierarchy, which is the process that is used to select the code that 'builds' the page. Within the template is the code that will display images, content, etc.
You will also want to learn about "Child Themes", which is a way of customizing a theme without affecting the theme code. You don't want to modify the theme's code because any changes you make will be overwritten by a theme update.
You might also consider contacting the theme's support forum to ask questions there about your theme. You have already determined the theme is at fault, so the theme's support is the place to ask questions about theme problems.
So, the template is what needs to be changed. And to do this properly, create a Child Theme and copy your theme's template in there, and modify that code. | stackexchange-wordpress | {

Add custom post type archives to search results?
How do I get WP search results to include custom post type (CPT) archives? For example, if I have CPT `'career'` whose title (in the template php) is 'Careers', how do I get search results to include the CPT archive URL (www.my-domain.com/careers) for "careers", "career", "jobs".
I suppose the question might be, can one insert their own results into search, and how?
I am/can optionally use the Relevanssi search plugin as well. I installed that to try and solve this problem, but it seems that alone is not enough.
Thank you for your attention. | WordPress will not return a post type archive page in search results. Relevanssi might work, but a slightly easier route is to create a custom page template that lists the `career` items. Name the page "Careers" and it will show up in search results.
Another advantage to this approach is that the page's text content can be displayed above the listing of `career` items, meaning you can manage that in WordPress rather than hard-coding that text in the template.
There are disadvantages as well - paginating the `career` items is significantly more complex, so you may be tempted to disable pagination entirely and display them all on a single page. If you have dozens or hundreds of items, that is not a good idea. | stackexchange-wordpress | {

How to add / embed an author into REST data from a custom post type?
We have a couple of post types which don't directly support authors. Instead, we have custom interfaces for choosing the author.
We end up with an author ID, though, so I'd like to inject that author ID into the REST data for that custom post type.
I've tried this:
add_filter( 'rest_post_dispatch', function( $results ) {
$result->add_link( 'author', rest_url( '/wp/v2/users/42' ), array( 'embeddable' => true ) );
return $results;
});
… but that returns the link on the entire response (e.g. a set of 10 custom posts) -- what I want to be able to do is, for each post, add a link with that post's own user ID.
Is this possible? I can't find documentation anywhere -- the best I found was this old page on Linking. | I found out how to grab each result and add a link. For the `ananda_video_audio` post type:
add_filter( 'rest_prepare_ananda_video_audio', function( $results ) {
// These two lines are unique to our code of course
$video = new Ananda_Video_Audio( $results->data['id'] );
$authors = $video->get_author_IDs();
foreach( $authors as $author_id ) {
$results->add_link( 'author', rest_url( '/wp/v2/users/' . $author_id ), array( 'embeddable' => true ) );
}
return $results;
});
Because embeddable is set to true, the author data all gets added to _embedded as well, in the response. Works great.

add_rewrite_rule ignoring other params than the "p" param
A specific post on my website has a shortcode that uses a parameter called "query" to produce its content. So, this is an example of a working URL:
"my-post" is the permalink of the post and the page is using the "query" param correctly.
However, we need to change this URL to a friendly one like < and then I was trying to use the `add_rewrite_rule` like this:
function custom_add_rewrite_rules() {
add_rewrite_rule(
'^something-here/([\d]+)$',
'index.php?p=10219&query=$matches[1]',
'top'
);
}
add_action('init', 'custom_add_rewrite_rules');
When I try to access the friendly URL, I'm redirected to < successfully, but the **query** param is null (`$_GET["query"] = null`).
I also tried making use of `add_rewrite_tag` to register "query", but with no success.
If anyone has some light to shed it'd be more than appreciated. | It sounds like the plugin expects there to be a get param.
Your rewrite-rule is removing the get-param before it can be used by the plugin.
If the plugin hasn't been updated for a long time (it's abandonware) then you can go through the plugin and replace the get-param with the portion of the url which would have been the get-param. Just make sure to prevent the plugin from updating after you've made your edits.
If you add the following
function custom_add_rewrite_rules() {
add_rewrite_tag('%query%','([^&]+)');
add_rewrite_rule(
'^something-here/([\d]+)$',
'index.php?p=10219&query=$matches[1]',
'top'
);
}
add_action('init', 'custom_add_rewrite_rules');
& then replace `$_GET['query']` &/or `$_REQUEST['query]` with `get_query_var( 'query' )` in the plugin you've described, that should be enough to do the trick.

How to display latest posts with authors image
how can U get latest posts from a specific category and post them with the picture of the author. All authors are signed as an author on WordPress and they all have profile picture. Actually it will stand for columns side like this ;
$postslist = get_posts( $args );
foreach ($postslist as $post) :
setup_postdata($post);
?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<h4><?php the_author();?></h4>
<?php
the_excerpt();
echo get_avatar(get_the_author_meta());
endforeach;
?>
In the example the category id is set to 12 - just replace it with the id of the category you want to use.

URL rewrite problem in WordPress plugin
I am having some trouble getting rewrite rules to work as I want in my a WordPress plugin.
I added a rewrite rule:
add_rewrite_rule('some_url','some_redirected_url', 'top');
The rule is written to .htaccess and the rule works as expected; when inspecting the $_SERVER variable I get the following:
> $_SERVER['REDIRECT_URL']='some_redirected_url'
>
> $_SERVER['REQUEST_URI']='some_url'
However, WordPress is parsing $_SERVER['REQUEST_URI'] for request arguments so the redirected request is not parsed.
In other words, if I go to < the request is not working, even if the redirect works. If I go directly to < everything works correctly.
How can I make WordPress parse the redirected URL? | If you want a rewrite rule that loads a post type archive from a different URL, the simplest way is via an internal rewrite, which doesn't get inserted into .htaccess. Internal rewrites map URLs to query arguments, and must result in a successful main query:

'some_url/?$',
'index.php?post_type=yourcpt',
'top'

Which cache is kicking
I have been struggling with a site that I inherited from another developer.
My main problem is that, changes I make in the css file of the template don't get picked up right away, indicating that some kind of caching is kicking in. What I checked is.
1. The .htaccess file for any caching directive.
2. Any caching WordPress plugins that might be activated.
3. Any caching functionality implemented by the hoster.
4. Cloudflare or any other CDN.
5. [EDIT] I have tried different browsers and computers so the caching is server side.
As you can imagine none of the above is enabled and yet my changes to the css take some hours to be seen.
I am not a WordPress expert in any way, so I am asking the community of what other caching mechanism I might missing here.
Thanks | You could change the file version each time the file gets updated. To do this, go to your `functions.php` file and find where the style-sheet is being enqueued (or registered) - it will look something like:
wp_enqueue_style( 'theme-style', get_template_directory_uri() . '/style.css' );
and change it to:
wp_enqueue_style( 'theme-style', get_template_directory_uri() . '/style.css', array(), filemtime( get_template_directory_uri() . '/style.css' ) );
This will change the file version each time you save it, forcing the new version to get loaded.

how to bulk add one line in the first paragraph of all posts
I want to add a sentence at the beginning of all posts of content directly into the post_content WordPress database. How do I? Either through the `function.php` or the MySQL command. | I'd go for solution posted by @butlerblog - it's a lot easier to manage and change in the future and it's better WP practice.
But... If you're asking... Here are the ways you can do this:
## 1\. WP way:
function prepend_content_to_posts() {
$to_prepend = 'This will be prepended';
$posts = get_posts( array( 'posts_per_page' => -1 ) );
foreach ( $posts as $post ) {
wp_update_post( array(
'ID' => $post->ID,
'post_content' => $to_prepend . $post->post_content
) );
}
}
Then you'll have to call that function. Be careful not to call it twice - it will add your content twice in such case.
## 2\. MySQL way:
UPDATE wp_posts
SET post_content = CONCAT('<YOUR STRING TO PREPEND>', post_content)
WHERE post_type = 'post' AND post_status = 'publish'

When `error_reporting` includes `E_NOTICE`, you would probably get an error such as:
> Notice: Use of undefined constant REQUEST_URI - assumed 'REQUEST_URI' in _< file path>_ on line _< line number>_
But if there is a constant with this name, PHP will use the constant’s value instead. (See also Array do's and don'ts)
**So always use quotes when you mean a string.** Otherwise it can have unwanted side effects.

WooCommerce Template overriding not working with woocommerce.php
I am creating a custom theme with my own HTML. I am trying to override woocommerce template. I have created a template named with `woocommerce.php` but it still shows template with default structure.
I checked the system status and it says that `Your theme has a woocommerce.php file, you will not be able to override the woocommerce/archive-product.php custom template since woocommerce.php has priority over archive-product.php. This is intended to prevent display issues.`
But when I load the `shop page` it opens up with default structure.
Some screenshots

2. WooCommerece system status
3. woocommerece.php | I fix that by disabling Woocommerce template debug mode in config.php.
define( 'WC_TEMPLATE_DEBUG_MODE', false );

Can't access wp-admin Internal Server Error 500
I suddenly can't access `company.co.za/wp-admin`, as it redirects to
with error 500
What should I do to resolve this?
I know I can try disabling all plugins, but how do I do that without loggin into wp dashboard? Is there some other step I should take?
Thank you | There are so many for internal server error. The main reasons for internal server errors are.
1. Corrupt .htaccess file
2. PHP Memory limit
3. Corrupted plugin
4. Incompatible PHP version
5. Corrupted core files
In oder to fix this issue, you need to investigate in step by step order.
To solve this issue first of all you need to enable Debug mode and check the issue. after that try with restoring .htacess file, enabling default theme, disabling plugins etc.

Found a translation function that is missing a text-domain. Function _n

UPDATE
The error is gone when `$field['min']` was assigned to a variable. I am i doing it correct? | Your error (actually a warning) seems to come from the Theme Check plugin.
There's nothing wrong with the code you're showing above. `'acf'` is your text domain. and the _n function takes four arguments as you've given it.
It strikes me that the Theme Check plugin is not very good at static analysis of function calls. I actually get a different warning with your code (possibly a later version) It seems it can't cope with array expressions like `$field['min']`. But of course WordPress/PHP will execute this just fine.
As you discovered yourself, assigning a variable gets rid of the warning. So doing something like the following is absolutely fine and seems to satisfy Theme Check's code scanner.
$n = $field['min'];
$valid = _n( '....', '....', $n, 'acf' );

Query posts by custom fields (object post)
As described in ACF documentation, here is the way to find all posts where a custom field called ‘color’ has a value of ‘red’.
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_key' => 'color',
'meta_value' => 'red'
));
But in my case, I need to find all posts where the ID of an object post custom field has a certain ID.
How should I proceed to handle **meta_value** as an object, and targeting its ID key? | If you use Post Object field type, then it is stored as ID in custom field. So this should do the trick:
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_key' => '<FIELD_NAME>',
'meta_value' => <POST_ID>
));
PS. You should use 'posts_per_page' instead of 'numberposts' (which is deprecated). | stackexchange-wordpress | {

How to update the children of a post?
i found nothing about it in the WP reference and Google, so i ask you: I want to update a post by a form - and with it its children.
$post = array(
'ID' => $mainid,
'post_status' => 'wartend'

$lead = wp_update_post($post);
$children = get_children( $mainid );
foreach ($children as $child){
wp_update_post(
array(
'ID' => $child,
'post_status' => 'wartend',
'post_parent' => $mainid
)
);

The post is getting updated, but not the children. | `get_children` returns an array of post objects by default:
<
So you would have to use `'ID' => $child->ID`, in this case... also my want to wrap the foreach with `if (count($children) > 0) {}` to prevent possible errors where there are no children. ie:
$children = get_children( $mainid );
if (count($children) > 0) {
foreach ($children as $child){
wp_update_post(
array(
'ID' => $child->ID,
'post_status' => 'wartend',
'post_parent' => $mainid

How can I change preview URL?
How can I change the preview URL in Wordpress?
When creating a post in Wordpress, there is a `Preview` button which takes you to the draft view. Because I have a custom integration of Wordpress and don't use a theme, I would like to change the URL of the preview link. Is this possible? How?
Regarding the custom implementation, Wordpress posts are integrated in another framework. I do this by setting `WP_USE_THEMES` to `false`, loading `wp-config.php` and directly accessing the posts using `WP_Query()`. This means I am bypassing any Wordpress theme that is set. | You can do something like this, add to functions.php

WooCommerce add_to_cart
I'm creating a WooCommerce product programmatically (Create product via CRUD) and wants to add it to its cart.
Code I'm using is marked as legacy (WC_Cart)
$cart = new WC_Cart();
$cart->add_to_cart($product_id);
**The question:** Is there a newer way to add product(s) to the cart? | > **The question:** Is there a newer way to add product(s) to the cart?
Well, `WC_Cart::add_to_cart()` is still the way to do it.
Except (on the front-end), there's no need to reinstantiate the cart class:
$cart = new WC_Cart();
because the main WooCommerce class already instantiates `WC_Cart`, and you can easily access the class instance like so:
$cart = wc()->cart;
//$cart = WC()->cart; // same as above, but wc() (i.e. lowercase) is actually preferred :)
where `wc()` is a wrapper function that returns the main instance of the main WooCommerce class.
And to add a product into the cart, you can use either of these options:
// Option #1
wc()->cart->add_to_cart( $product_id );
// Option #2: Here we assign wc()->cart to a variable.
$cart = wc()->cart;
$cart->add_to_cart( $product_id );

Password Protect content() on homepage
I need to password protect several pages and various areas of my templates if the page had a password enabled. This I can do on all subpages but on the homepage it's just not working.
I do not want to whole site password protected, which many plugines seem to do - the built-in WP password protection is fine for this purpose apart from the homepage issue. When the visitor lands on the site, they can see elements of the page but some content is hidden. The content needs to be unlocked by just a password and not a registered WP account username/password.
I assume the page used as home is treated differently than "normal" pages.
The only thing I can think of is to instantly redirect the homepage to a "normal" pge that looks identical - then the password protection function would work?
Google just offers either protecting the whole site (ie all you see in a login page) or protecting a normal page or using registered accounts to unlock content. | You can make the homepage password protected by creating a page and selecting it in the admin Settings > Reading > Homepage Displays. Then on the page settings make it password protected.
Then create a template called front-page.php and use conditionals to show/hide the content.
For Example...
if ( ! post_password_required( $post ) ) {
// Password Protected Content
}else{
// Password Form
echo get_the_password_form();
}
