ARRAY_FILTER WARNING-wp-Includes/post.php第3148行

我插入the following code, 请参见下文，从前端提交帖子。提交时，会出现以下警告：

警告：array\\u filter（）要求参数1为数组，字符串在[…]中给出/wp包括/后。php在线3148

我不知道警告来自哪里，哪个数组是字符串？

Array Formation Issue

我正在运行SQL查询，以获取当前登录用户的post ID。我的查询按设计工作。$userGadgets = $wpdb->get_results(\"SELECT item_id FROM mg_gd_mylist WHERE user_id = \'$user_id\'\", ARRAY_A); 我面临的问题与返回的数组有关。array( 16 ) { [0]=> array( 1 ) { [\\\"item_id\\\"]=>
