Definido em:

Deletes a post meta field for the given post ID.

You can match based on the key, or key and value. Removing based on key and value, will keep from removing duplicate metadata with the same key. It also allows removing all metadata matching the key, if needed.


function delete_post_meta( $post_id, $meta_key, $meta_value = '' ) {
	// Make sure meta is added to the post, not a revision.
	$the_post = wp_is_post_revision( $post_id );
	if ( $the_post ) {
		$post_id = $the_post;

	return delete_metadata( 'post', $post_id, $meta_key, $meta_value );
