rwmb_before_delete_field

These actions run when you delete a field value with rwmb_delete_meta().

do_action( 'rwmb_before_delete_field', $object_id, $key, $args );
do_action( 'rwmb_after_delete_field', $object_id, $key, $args, $result );

They have these parameters:

Name	Description
`$object_id`	The object ID
`$key`	The field ID
`$args`	The arguments of `rwmb_delete_meta()`, such as `object_type`
`$result`	Only for `rwmb_after_delete_field`. `true` if the value is deleted, `false` if not.

These actions do not run when users clear a field in the edit screen. For that case, use rwmb_after_save_field.

Example

Log deleted values:

add_action( 'rwmb_after_delete_field', function ( $object_id, $key, $args, $result ) {
    if ( $result ) {
        error_log( "Deleted field $key of object $object_id" );
    }
}, 10, 4 );
