Restrict read access to own content in admin pages

Sometimes, you need to restrict users to only be able to see their own posts in the site’s backend.

You cannot do this using Toolset Access rules, so a custom code is needed.

Use Toolset to add the following code to your site, to a

Code Snippet

<?php
toolset_snippet_security_check() or die( 'Direct access is not allowed' );
add_filter( 'pre_get_posts', 'tssnippet_view_own_posts_in_admin' );
function tssnippet_view_own_posts_in_admin( $query ) {
    global $pagenow;

    if (
        'edit.php' != $pagenow
        || ! $query->is_admin
    ) {
        return $query;
    }

    if( ! current_user_can( 'edit_others_posts' ) ) {
        global $user_ID;
        $query->set( 'author', $user_ID );
    }

    return $query;
}
