Apparently the serialized data got corrupt, calling the field by query got me this error. WordPress does not return an error when the serialized data is corrupt just a bool(false). Solved this by insert/update the serialized data in a base64_encode() and call it with base64_decode(). This seems to do the trick and data can be … Read more

A little late, but I just had this issue where adding a taxonomy term was working, but adding post meta wasn’t. The solution was to set a higher priority. The default priority is 10, so try for instance priority of 100: add_action( ‘save_post_dealer’, ‘save_dealer_long_lat’, 100, 1);
OK, so you have some code that uses add_post_meta and you want to make it add only unique values. The problem in here is that add_post_meta does exactly what it’s name is saying – it adds a post meta value. There is 4th arg for that function that’s called unique, but it work based on … Read more
Running the wp media regenerate command from WP-CLI with the –only-missing argument is quite fast (takes about 30 seconds for 4000 images) and rebuilds _wp_attachment_metadata correctly: wp media regenerate –only-missing
You can get using this using SQL global $wpdb; // For single record $wpdb->get_row(“SELECT post_id FROM $wpdb->postmeta WHERE meta_key = $param1 AND meta_value = $param2”); // For multiple records $wpdb->get_results(“SELECT post_id FROM $wpdb->postmeta WHERE meta_key = $param1 AND meta_value = $param2” ); Use this for query $args = array( ‘posts_per_page’ => 10, // -1 for … Read more
WordPress fires the updated_{$meta_type}_meta hook which fires after the metadata is updated. In your case, the hook would be updated_post_meta and you could have your function run on that hook instead of the save_post hook.
This question is possibly a duplicate of: Only show metabox when date-value in other metabox is over? Broadly there are two ways of achieving this. Using the add_meta_boxes hook to pass two variables: post type and the post. Then add the metabox only when the post has a certain term: add_action( ‘add_meta_boxes’, ‘myplugin_add_my_custom_box’,10,2); function myplugin_add_my_custom_box($post_type,$post){ … Read more
You can insert an associative array into the post_meta_field. Here is a quick little function to grab the data afterward (did not test): function grab_task_name_array($post_id) { $new_array = array(); $array = get_post_meta($post_id,’_task-name’); //do not put true as third parameter (this would return string and not array) foreach($array[0] as $key => $value) $new_array[$key] = $value; return … Read more
Two things I could imagine: Check the post_modified value. Maybe import creates a definitive timestamp that you could use. You’ll still have to save the import date somewhere so you can check against it. I do some post importing via a stream/HTTP response (this is not the native importer). During the import, I map my … Read more
