Wordpress:上传时发生错误 [英] Wordpress: An error occurred in the upload

问题描述

更新到 WordPress 3.5 后，我在以非管理员用户身份使用添加媒体"按钮上传文件时开始收到以下错误:

After updating to WordPress 3.5, I started getting the following error when uploading files using the Add Media button as a non-admin user:

错误:上传时发生错误.请稍后重试.

图片似乎已经上传完毕，但在最后出现此错误消息.

The image seems to finish uploading, but right at the end this error message appears.

这不会发生在管理员身上，只会发生在其他角色身上.我什至尝试为另一个角色提供完整的管理权限，但错误仍然出现.

This doesn't happen for the administrator, only the other roles. I've even tried giving the other role full admin capabilities, but the error still appears.

这是一个错误吗?还是我遗漏了什么?

Is this a bug? Or am I missing something?

推荐答案

经过反复试验，我终于找到了适合我的解决方案.

After much trial and error, I finally found a solution that worked for me.

首先，我发现上传自定义用户角色的文件需要以下角色能力:

First, I found the following role capabilities to be required to upload files for custom user roles:

$capabilites = array(

    'read'                  => true,
    'upload_files'          => true,
    'edit_published_pages'  => true,
    'edit_others_pages'     => true

);

我不确定为什么特别需要这些，但如果没有它们，错误就会不断发生.

I'm not sure why these are specifically required, but the error kept occurring without them.

其次，我必须更新我用来防止非管理员用户访问仪表板的功能:

Second, I had to update a function I was using to prevent non-admin users from accessing the Dashboard:

function redirect_nonadmin_fromdash(){

    if($_SERVER['PHP_SELF'] == '/wp-admin/async-upload.php'){

        /* allow users to upload files */

        return true;

    } else if(get_user_role() != 'administrator'){

        /* custom function get_user_role() checks user role, 
        requires administrator, else redirects */

        wp_safe_redirect(home_url());
        exit;

    }

}

add_action( 'login_form_login', 'redirect_nonadmin_fromdash' );
add_action( 'admin_init', 'redirect_nonadmin_fromdash', 1 );

之前，我正在检查 media-upload.php，但新的媒体上传器使用 async-upload.php.

Previously, I was checking for the media-upload.php, but the new media uploader uses async-upload.php.

因此，本质上，这允许非管理员用户从前端使用新媒体上传器，而不允许他们访问仪表板.

So, essentially, this allows non-admin users to use the new media uploader from the front-end without allowing them access to the Dashboard.

它还限制了他们对媒体库的访问，这对我来说也很重要.

It also restricts their access to the Media Library, which was also important to me.
