Found the solution in this post: update_post_meta and update_field ony working when saving the post The solution is to use update_field because update_post_meta uses a different method to update fields than ACF does. Do note that this is the correct order of using the code update_field($meta_key, $meta_value, $post_ID);.
So since attachments are post types, you should be able to assign them postmeta like any other post type. Using the update_post_meta function should get you where you need to be. update_post_meta( $attachment_id, ‘price’, $price ); http://codex.wordpress.org/Function_Reference/update_post_meta Then run your query based on a meta key. $args = array( ‘order’ => ‘ASC’, ‘post_type’ => ‘attachment’, … Read more
What qualifies as custom field? Yes, a custom field is equal to post metadata, but be aware that some metadata is only for internal use (usually prepended with an underscore, for example _edit_lock. A more detailed look at the function The function get_post_custom() is actually just a wrapper for get_post_meta(): (wp-includes/post.php line 1764), but with … Read more
Your Query is incorrect. To retrive meta values for triple meta_key you will need 3 different joins using posts meta on posts table. Check code below: // Example value $user_id = 1; // Calculate average post rating for user $ratings_query = $wpdb->get_results( $wpdb->prepare(” SELECT pmeta.meta_value FROM wp_posts LEFT JOIN $wpdb->postmeta AS pmeta ON (pmeta.post_id = … Read more
As mentioned in the comments, you are outside of the loop, so get_field will not know the ID. You can use the code below: <?php $meta_description = get_field(‘meta_description’, get_queried_object_id()); if(empty($meta_description)) { $meta_description = ‘This could be an interesting meta description’; } ?> <meta name=”description” content=”<?php echo $meta_description; ?> “/> If you use var_dump() in the … Read more
So I installed the Yoast SEO plugin, and tested your code, and now I can positively say “neither no nor yes, but you could” to this question: Please help not sure whether I should use this along with transition_post_status transition_post_status is fired before the wp_insert_post action is fired, and the Yoast SEO plugin is actually … Read more
The solution is to use a different hook which fires after post meta data has been saved by Gutenberg to the WP API. After reading this related discussion on Github and inspecting this code by n7studios, I discovered that rest_after_insert_post is a hook to use. So, the way to reliably check for the existence of … Read more
While you can do this with WP_Query, I’d do this the way you are trying to avoid– save a list in a separate key. The “pros” strongly outweigh the “cons” in my mind. LIKE queries with wildcards, especially with leading wildcards, are not efficient– aka, “slow” and a LIKE query on serialized data is going … Read more
I have found an answer at this article entitled “Excluding Categories from the_category();”: function the_category_filter($thelist,$separator=” “) { // list the IDs of the categories to exclude $exclude = array(4,5); // create an empty array $exclude2 = array(); // loop through the excluded IDs and get their actual names foreach($exclude as $c) { // store the … Read more
Use another custom field with the URL and call it something like leetpress_website_url then change your code to this: <?php if ( get_post_meta( $post->ID, “leetpress_website”, true ) ){ echo ‘<div class=”pros”><p><strong>Movie Website: </strong><a href=”‘ . get_post_meta( $post->ID, “leetpress_website_url”, true ).'”>’ . get_post_meta( $post->ID, “leetpress_website”, true ) . ‘</a></p></div>’; } ?>
