Delete post meta conditionally after save post

Well, first use the hook properly. The post ID will be passed in. You don’t need $post->ID. Second, use the correct hook. If you want to run save_post only for your booking type, use save_post_booking But otherwise, the code works. I just ran a quick test. function booking_status_is_updated($post_id){ if(get_post_meta($post_id,’booking_status’,true)==’denied’){ delete_post_meta($post_id,’booking_slot’); } } add_action(‘save_post_booking’,’booking_status_is_updated’);

Custom field value based on other custom field values

I recommend you look into the get_{$meta_type}_metadata filter. This is a basic hook setup to return a dynamic post meta value: <?php add_filter( “get_post_metadata”, function( $points, $post_id, $meta_key, $single ){ if ( ‘points’ == $meta_key && $single ) { update_post_meta( $post_id, ‘rank’, calculate_post_rank( $post_id, $points ) ); } return $points; }, 10, 4 );

Displaying custom posts only if custom meta box’s date is not expired

In your loop while(have_posts() ) : the_post(); you are unconditionally going through all posts, but since the loop stops after the_post() nothing actually happens. So that’s where the condition has to go: while(have_posts() ) { the_post(); if ($daysleft >= 0) { … other actions } } Your code looks a bit incomplete to me, so … Read more

Unable to show ACF’s Image Custom Field properly in Genesis Framework [closed]

Ok, so here’s the right answer, with the full code for an ACF Repeater Field: $count = get_post_meta( get_the_ID(), ‘items’, true ); if ( $count ) { for ( $i = 0; $i < $count; $i++ ) { $item_100x100 = intval( get_post_meta( get_the_ID(), ‘items_’ . $i . ‘_item_100x100’, true ) ); $item_200x200 = intval( get_post_meta( … Read more

Meta tags in shortcode

Since evasmat_posted_on() is a function in your theme, you don’t need to use get_post_meta to get the date. You can call the function directly so: function evasmat_posts_shortcode(){ $q = new WP_Query( array( ‘orderby’ => ‘date’, ‘posts_per_page’ => ‘4’) ); $list=”<div class=”cards”>”; while($q->have_posts()) : $q->the_post(); $list .= ‘<div class=”card”>’ . get_the_post_thumbnail() . ‘<h2 class=”entry-title-index”><a href=”‘.get_permalink().'”>’.get_the_title() .'</a></h2>’ … Read more

WordPress widget new instance creates content duplicates

I don’t see anything wrong with the widget class. The problem you have is that you are displaying the widget area, that contains the widgets, twice in your sidebar.php: <aside id=”secondary” class=”widget-area col-sm-12 col-md-12 col-lg-12″ role=”complementary”> <div class=”col-lg-6 col-md-12″> <?php dynamic_sidebar( ‘main-widget’ ); // this will display all the widgets in your main-widget sidebar ?> … Read more

Transition from (classical) serialized custom meta field to (gutenberg) rest enabled meta

Here’s an answer to question 1 that uses register_post_meta. It’s also the start of an answer to question 2 by use of the prepare_callback option in show_in_rest . add_action( ‘init’, ‘wpse_89033_register_custom_meta’ ); function wpse_89033_register_custom_meta() { $post_types = [ ‘post’, ‘page’, ‘attachment’, ]; foreach ( $post_types as $post_type ) { register_post_meta( $post_type, ‘_custom_key’, array( ‘type’ => … Read more

Explanation for remove_filter used in the below code [closed]

The remove_filter() is necessary to avoid the callback from being called recursively, which would result in a memory issue due to a never-ending function execution. And that recursion could happen because the callback is hooked to get_post_metadata which is invoked via the get_metadata() function which the callback calls. So you need to first “unhook”/unregister the … Read more
