我创建了一个名为product 并分配了一个新角色manager 为了它。除了媒体上传器product. 我甚至可以直接在add media 部分所以，我开始用默认值进行测试author, 还是一样的错误！令人惊讶的是author 可以在默认情况下成功上载图像post, 不在product!

错误消息显示：An Error occurred in the upload. Please Try again later.

以下是自定义帖子类型的代码：

function cpt_product() {
    $slug = \'product\';
    $labels = array( //all the custom labels );

    $args = array(
        \'labels\' => $labels,
        \'public\' => true,
        \'menu_position\' => \'5.1\',
        \'public\' => true,
        \'has_archive\' => true,
        \'supports\' => array( \'title\', \'editor\', \'author\', \'excerpt\', \'custom-fields\', \'revisions\' ),
        \'exclude_from_search\' => false,
        \'publicly_queryable\' => true,
        \'show_ui\' => true,
        \'capability_type\' => $slug,
        \'capabilities\' => array(
            \'edit_post\' => \'edit_\' . $slug,
            \'read_post\' => \'read_\' . $slug,
            \'delete_post\' => \'delete_\' . $slug,
            \'edit_posts\' => \'edit_\' . $slug . \'s\',
            \'edit_others_posts\' => \'edit_others_\' . $slug . \'s\',
            \'publish_posts\' => \'publish_\' . $slug . \'s\',
            \'read_private_posts\' => \'read_private_\' . $slug . \'s\',
            \'delete_posts\' => \'delete_\' . $slug . \'s\',
            \'delete_private_posts\' => \'delete_private_\' . $slug . \'s\',
            \'delete_published_posts\' => \'delete_published_\' . $slug . \'s\',
            \'delete_others_posts\' => \'delete_others_\' . $slug . \'s\',
            \'edit_private_posts\' => \'edit_private_\' . $slug . \'s\',
            \'edit_published_posts\' => \'edit_published_\' . $slug . \'s\'
        ),
        \'map_meta_cap\' => true
    );

    register_post_type( $slug, $args );     
}

下面是自定义角色的代码manager

function add_manager () {
$role_manager = \'manager\' ;
$displayname_manager = \'Manager\';
$capabilities_manager = array (
    \'read\' => true,
    \'edit_product\' => true,
    \'read_product\' => true,
    \'delete_product\' => false,
    \'edit_products\' => true,
    \'edit_others_products\' => true,
    \'publish_products\' => true,
    \'read_private_products\' => true,
    \'delete_products\' => false,
    \'delete_private_products\' => false,
    \'delete_published_products\' => false,
    \'delete_others_products\' => false,
    \'edit_private_products\' => true,
    \'edit_published_products\' => true,
    \'edit_posts\' => true,
    \'upload_files\' => true
    );


    create_custom_role ( $role_manager, $displayname_manager, $capabilities_manager );
}
add_action(\'admin_init\', \'add_manager\');


function create_custom_role ( $rolename, $roledisplayname, $capabilities ) {
    if ( get_role ( $rolename ) ) {
        return 0;
    }
    else {
        add_role ( $rolename, $roledisplayname, $capabilities );
    }
}

现在我完全迷失在这里，找不到解决办法！谁能帮帮我，告诉我我错过了什么，或者做错了什么(
