Module::get_tag_value_field( $this) needs to return an array. https://www.php.net/manual/en/function.list.php You could check for this to avoid an error: $field = []; $meta_key = null; // Maybe that shoud be = new stdClass(); $tmp = Module::get_tag_value_field($this); if (is_array($tmp) && array_key_exists(0, $tmp) && array_key_exists(1, $tmp)) { list($field, $meta_key) = $tmp; }
