我有一个用于从页面编辑视图（post.php？action=edit）上的复选框填充的函数。在编辑器页面上呈现元盒时，我调用此函数。

function get_available_attachments() {
    global $post;

    $attachments = [];
    $attach_query = new WP_Query([
        \'post_type\' => \'attachment\',
        \'post_status\' => \'inherit\', // default is \'publish\'
        \'post_mime_type\' => \'application/pdf\',
        \'orderby\' => \'name\',
        // \'orderby\' => \'date\',
        \'order\' => \'DESC\',
    ]);

    while($attach_query->have_posts()) {
        $attach_query->the_post();
        $attachments[] = (object)[
            \'mime_type\' => $post->post_mime_type,
            \'title\' => $post->post_title,
            \'ID\' => $post->ID
        ];
    }

    wp_reset_postdata();

    return $attachments;
}

出于某种原因，当我保存/更新帖子时，the permalink is changed to having the slug of an attachment! 我想wp_reset_postdata(); 会阻止依恋的干扰，但我不知道发生了什么。在我挂接到的save\\u post操作中，我只收到一些附件的数字ID，不再调用该函数。

EDIT for more info如果我回应后段塞，这就是行为：

function get_available_attachments() {
    global $post;
    echo $post->post_name .\'<br>\'; // correctly page slug

    $attachments = [];
    $attach_query = new WP_Query([
    // ...

    echo $post->post_name .\'<br>\'; // correctly an attachment slug
    wp_reset_postdata();
    echo $post->post_name .\'<br>\'; // INCORRECT still attachment slug

不知怎么的wp_reset_postdata(); 不起作用

function get_available_attachments( $post /* This is the post object being edited */ ) {
    $attachments = [];
    $attach_query = new WP_Query([
        \'post_type\'      => \'attachment\',
        \'post_status\'    => \'inherit\', // default is \'publish\'
        \'post_mime_type\' => \'application/pdf\',
        \'orderby\'        => \'name\',
        // \'orderby\'     => \'date\',
        \'order\'          => \'DESC\',
    ]);

    foreach ( $attach_query->posts as $att ) {
        $attachments[] = ( object ) [
            \'mime_type\' => $att->post_mime_type,
            \'title\'     => $att->post_title,
            \'ID\'        => $att->ID
        ];

    }

    return $attachments;
}
