admin page redirect

Question

Is it possible to redirect users to an admin page if they access another admin page?

For example if they a user ever hits "all pages" /wp-admin/edit.php?post_type=page

they would get redirected to "add New page" /wp-admin/post-new.php?post_type=page

Answer 1

/**
 * Redirect admin pages.
 *
 * Redirect specific admin page to another specific admin page.
 *
 * @author Michael Ecklund
 * @access public
 *
 * @return void
 */
public function disallowed_admin_pages(){
    global $pagenow;
    /* Check current admin page. */
    if($pagenow == 'edit.php' && isset($_GET['post_type']) && $_GET['post_type'] == 'page'){
        wp_redirect(admin_url('/post-new.php?post_type=page', 'http'), 301);
        exit;
    }
}

Fire the above function on the hook admin_init.

add_action('admin_init', array($this, 'disallowed_admin_pages'));

Answer 2

Yes this is possible by adding an action to admin_init, at that point you could check the request uri to see if it matches /wp-admin/edit.php?post_type=page and if it does issue a redirect to the add posts page: /wp-admin/post-new.php?post_type=page.

Also the Plugin API and the action reference pages on the WordPress codex go into more detail about actions and how they work.
