我试图返回特定查询的帖子。使用以下代码：

$meta_query = array(
    \'relation\' => \'OR\',
    array(
        \'key\'     => \'tic_assignment\',
        \'value\'   => $current_user -> ID,
        \'compare\' => \'=\',
    ),
    array(
        \'key\'     => \'tic_department\',
        \'value\'   => $_depts,
        \'compare\' => \'LIKE\',
    ),
);
$_args = array ( \'post_type\' => \'tickets\',
    \'meta_query\' => $meta_query,
    \'posts_per_page\' => 10, 
    \'orderby\' => \'date\', 
    \'order\' => \'DESC\', );
$the_query = new WP_Query( $_args );

现在，它不再根据添加的查询返回我的帖子，而是返回所有帖子。

我有var_dump教育部$the_query 返回的内容如下：https://pastebin.com/PPYaJpSu

（它太大了，不能全部粘贴在这里）

即使我取出第二个数组，它仍然返回所有内容。。。当它不应返回任何基于tic_assignment

当我将参数修改为：

$_args = array ( \'post_type\' => \'tickets\',
    \'meta_key\' => \'tic_assignment\',
    \'meta_value\' => $current_user -> ID,
    \'meta_compare\' => \'=\',
    \'posts_per_page\' => 10, 
    \'orderby\' => \'date\', 
    \'order\' => \'DESC\', );
$the_query = new WP_Query( $_args );

构造正确的查询，并返回正确的结果。

有什么好处？

$meta_query = array(
    \'relation\' => \'OR\',
    array(
        \'key\'     => \'tic_assignment\',
        \'value\'   => $current_user -> ID,
        \'compare\' => \'=\',
    ),
    array(
        \'key\'     => \'tic_department\',
        \'value\'   => $_depts,
        \'compare\' => \'LIKE\',
    ),
);
$_args = array ( \'post_type\' => \'tickets\',
    \'meta_query\' => $meta_query,
    \'posts_per_page\' => 10, 
    \'orderby\' => \'date\', 
    \'order\' => \'DESC\', );
$the_query = new WP_Query( $_args );
