How can I have users only see their content in WordPress?

1 Views

This goes beyond posts and media. I have several CPT’s and a calendar. Is there a way to have wordpress check the user name and only show content they have created?

  1. In the backend, to filter all post types that are shown and restrict the visualization you can use pre_get_posts.

    add_action( 'pre_get_posts', 'users_own_content_so_12761756' );

/**
 * Show only posts of the current user in the dashboard
 * affects posts, pages, media and custom post types
 */
function users_own_content_so_12761756( $wp_query_obj ) 
{
    // Restrict hook to the backend
    if( !is_admin() )
        return;

    global $current_user;
    get_currentuserinfo();

    // http://php.net/manual/en/function.is-a.php
    if( !is_a( $current_user, 'WP_User') )
        return;

    if( !current_user_can( 'administrator' ) )
        $wp_query_obj->set( 'author', $current_user->ID );
}

    After applying this code, you’ll notice that the post count is not correct: it’ll show the total count and not the user count. To adjust that, refer to this Q&A: Update post counts (published, draft, unattached) in admin interface.

    You’ll need to care about user roles and capabilities as well, blocking the rights to edit someone else’s posts/pages/cpts. That’s because a user can type in the browser address example.com/wp-admin/post.php?post=POST_ID&action=edit and access the post, if he/she has the rights to do so.

  2. you can try adding this to the loop

    <?php $author = get_the_author(); 
$current_user = wp_get_current_user(); 
if($author != $current_user->user_nicename) {
    echo "permission denied";
    break;
} ?>
