我有一个CPT来代替我的“post”post类型，但我仍然需要能够使用附件。问题是，附件具有post功能。

我不想给我的角色赋予post功能，因此，我试图找到一种方法来避免它。

我在wordpress的跟踪中发现了一个黑客：http://core.trac.wordpress.org/ticket/19834

function crunchhack() {
   global $wp_post_types;
   $wp_post_types[\'attachment\']->cap->edit_post = \'upload_files\';
}
add_action( \'init\', \'crunchhack\' );

我已将其添加到functions.php. 它不起作用，因此，我尝试用upload_files:

function fix_media_permissions() {
    global $wp_post_types;
    $wp_post_types[\'attachment\']->cap->edit_post = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->read_post = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->delete_post = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->edit_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->edit_others_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->edit_published_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->publish_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->delete_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->delete_others_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->delete_published_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->delete_private_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->edit_private_posts = \'upload_files\';
    $wp_post_types[\'attachment\']->cap->read_private_posts = \'upload_files\';
}
add_action( \'init\',  \'fix_media_permissions\');

遗憾的是，这也行不通。我可以看到上传的图片，但仅此而已。有什么想法吗？
