Getting meta data from a WP_Post object is already possible. Just write: echo $post->your_meta_key; This will call get_post_meta( $this->ID, $your_meta_key, true ) behind the scenes. See the documentation and the source code for WP_Post. This works also with instances of WP_User, but not with WP_Comment as far as I know. Don’t forget to escape the … Read more
$post->ID is what makes the meta value distinguished across all posts with the same meta key. So if you want to shorthand the get_post_meta call for the current post you can do this: function get_cuurent_post_meta($key){ global $post; return get_post_meta($post->ID,$key,true); } and you can call it like this: echo get_cuurent_post_meta(‘custom_tags’.$userID); Now if its not the current … Read more
You can use a simple query to get a distinct list of user-entered meta_keys for a specific post type, then cache the results using the Transients API. The meta keys from this query will be those that do not start with an underscore or number. function generate_foods_meta_keys(){ global $wpdb; $post_type=”foods”; $query = ” SELECT DISTINCT($wpdb->postmeta.meta_key) … Read more
I found the following filter, here unlocking all protected meta data: add_filter( ‘is_protected_meta’, ‘__return_false’ ); Or it can be fine tuned: add_filter( ‘is_protected_meta’, function( $protected, $meta_key, $meta_type ) { $allowed = array( ‘_edit_lock’, ‘_test’, ‘_wp_page_template’ ); if( in_array( $meta_key, $allowed ) ) return false; return $protected; }, 10, 3 ); It allows to display the … Read more
This function worked for me: function get_complete_meta( $post_id, $meta_key ) { global $wpdb; $mid = $wpdb->get_results( $wpdb->prepare(“SELECT * FROM $wpdb->postmeta WHERE post_id = %d AND meta_key = %s”, $post_id, $meta_key) ); if( $mid != ” ) return $mid; return false; } it will return an array of objects like: Array ( [0] => stdClass Object … Read more
You could use the empty function inside your if as such : <?php if( empty( get_post_meta( $post->ID, ‘price_list_category1’, true ) ) ) : ?>style=”display:none;”<?php endif; ?> The above returns an error, you should assign the return value to a variable. See my edit below. Warning empty might not be the best option depending on the … Read more
There is a plugin called Search everything, where you can break down what you want to search. It does custom fields, posts and of course titles.
Whenever you use the function get_post_meta(), the above query will be performed to get all post meta and store in the cache. The more posts you query, the more queries are made. To reduce the number of queries, we should pre-cache all meta values of all posts in the query before calling get_post_meta. This is … Read more
On the initial issues, are you positive the plugin is registering the fields to be made available to the api? the register_meta needs show_in_rest => true assigned. Also, the CPT needs custom-fields in its supports array, ‘supports’ => array(‘title’,’editor’,’thumbnail’,’custom-fields’) for that to made available when accessing the CPTs api endpoint. I cover that (with links, … Read more
I am just incredible stupid here as this can be easily done by a simple WP_Query: new WP_Query( array( ‘post_type’ => ‘shop_order’, ‘meta_key’ => $meta_key, ‘meta_value’ => $meta_value ) ) However, I decided to compare the actual generated SQL of the get_posts() with a ‘post_where’ filter solution which is: SELECT wp_posts.ID FROM wp_posts WHERE 1=1 … Read more
