I am working on a clients site, one of the features they want is for his Editors or Authors to only be able to select existing images to insert into Posts from the Media Library.

So looking at the media manager/upload screen below, is it possible to make the Upload Files tab to only be visible to Admin Users and also to make the Media Library shown by Default when this Dialog is shown?

  • You may want to check out the Adminimize plugin, there are a variety of different options that may fit your needs. – Charles Jul 13 '13 at 14:55
  • This plugin does just hide it with CSS. When I open up the developers tools or FireBug (or whatever browser you use), you can simply remove display: none; and can access everything. – kaiser May 18 '14 at 15:11

Method 1:

Remove the upload_files capability from the respective roles.

e.g. removing it from author:

$role = get_role( 'author' );
$role->remove_cap( 'upload_files' );

This is saved to the database so it should only happen once, not on every page load. Removing it from the editor role should be the same albeit with the obvious modification. Removing the capability will have the desired effect, but it may have additional effects you may not find so desirable, the only way to be sure is to test

Method 2

Consider this code, which will make the upload error out if the user does not have admin privileges.

<?php
/**
 * Plugin Name: Admin Only Uploads
 * Description: Prevents Uploads from non-Admins
 * Author: TJNowell
 * Author URI: http://tomjn.com
 * Version: 1.0
 */

function tomjn_only_upload_for_admin( $file ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        $file['error'] = 'You can\'t upload images without admin privileges!';
    }
    return $file;
}
add_filter( 'wp_handle_upload_prefilter', 'tomjn_only_upload_for_admin' );

You can make use of this filter to be more specific than upload_file, e.g. preventing the upload of images, and only images, but allowing audio, etc

  • Doesn't this remove the entire media library? – onetrickpony Jul 6 '13 at 18:30

    Hence method #2 – Tom J Nowell Jul 6 '13 at 20:03
  • Method #2 works like a charm! My setup: some images are uploaded by the admin, while other users can only view the admin's images and cannot upload their own. Cheers! – liviucmg Jan 17 '15 at 19:12
  • my client keep uploading the wrong file types (png, bmp !). Can is topped them using these mime types but still allow myself to upload .PNGs? – v3nt Jun 16 '17 at 9:41
  • @v3nt that's a new question, you should ask it on the site not in a comment – Tom J Nowell Jun 19 '17 at 17:30
