current_user_can capabilities in the admin not working as expected

Question

I'm trying to block admin dashboard access using wp_redirect().

But the results of using current_user_can('edit_post') are unexpected.

See my complete function below...

/**
 * user constructor method.
 */
public function __construct()
{

    // block admin dashboard access
    add_action( 'admin_init', array( $this , 'block_admin_access' ) );

}

/**
 * block admin dashboard access to users who cant edit posts
 */
public function block_admin_access () {

    // if users cannot edit posts
    if( ! current_user_can('edit_post') ) {

        // redirect user to home page
        wp_redirect( get_home_url() );

    }

}

When I am logged in as an administrator user, this code above blocks me from the dashboard. Administrators can definately edit posts, so why does this code above redirect me away from the dashboard?

When I am using current_user_can('edit_post') on the front end, the behaviour is normal.

Does anyone know why this could be?

Answer 1

With you current_user_can call everything is just fine. The problem lies elsewhere...

If you'll take a look at Roles and Capabilities, you'll see that there is no capability like edit_post. So your code is working correctly - admin can't edit_post, because there is no such capability (unless it's a custom capability registered by your code elsewhere).

But my gut tells me that you wanted to check if current user can edit_posts ;)
