update_post_meta() calls update_metadata which begins with this line: if ( !$meta_type || !$meta_key ) return false; I wrote a simple test (with a lot of cut & paste) to see how string values of 0 are evaluated (instead of looking it up in the PHP manual): <?php $meta_key = (string) 0; if ( ! $meta_key … Read more
I do need to add both post_meta: add_post_meta( $insert_q_key_id, ‘q_key_type’, (int)$q_key_type ); // Q Key Type And for ACF: update_field( “field_52c737a413e07″, (int)$q_key_type, $insert_q_key_id ); // Q Key Type And the rest of the answer “should” be covered by wp_set_object_terms: wp_set_object_terms( $insert_q_key_id, (int)$q_key_type, ‘q_key_type’, true ); However, this function is not fully available at the point … Read more
You should be fine deleting empty custom fields. The main reason is, that get_post_meta( $id, ‘metakey’, true ) returns an empty string if the field is not set, so it is the same as having an empty record set. get_post_meta( $id, ‘metakey’, false ), returns an empty array if no value is set, so you … Read more
Here is the code to get the download link for a downloadable product in WooCommerce. $downloads = $product->get_downloads(); foreach( $downloads as $key => $each_download ) { echo ‘<a href=”‘.$each_download[“file”].'”>Download</a>’; }
Try this. It will work. $prepare_guery = $wpdb->prepare( “SELECT post_id FROM $wpdp->posts where meta_key =’_Wps_crossells’ and meta_value like ‘%%d%'”, $meta_value ); $get_values = $wpdb->get_col( $prepare_guery ); Let me know it’s working or not.
$post->ID is what makes the meta value distinguished across all posts with the same meta key. So if you want to shorthand the get_post_meta call for the current post you can do this: function get_cuurent_post_meta($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 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
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
A standard WordPress schema “sync” via dbDelta() will only add indexes, not drop them. Same goes for fields. We never touch the storage schema either, so it’d be the default for MySQL (which in latest versions is now InnoDB). On the face, a comment_id_meta_key index makes perfect sense. But when you look at how WordPress … Read more
For NEW post type ‘post’ use draft_to_publish action hook: function fpw_post_info( $post ) { if ( ‘post’ == $post->post_type ) { // echo ‘<pre>’; print_r( $post ); echo ‘<br />’; // $meta = get_post_meta( $post->ID ); print_r( $meta ); echo ‘</pre>’; die(); // your custom code goes here… } } add_action( ‘draft_to_publish’, ‘fpw_post_info’, 10, 1 … Read more
