PHP: Show message to user e.g. Deleted

Question

How can I show a message when say something is deleted and it appends a query string on the end of a url when it redirects so for example: domain.com/?favor_trashed=294

and it would then show a message like:

<p>Favor has been successfully deleted</p>

Answer 1

Have a look into the Flash Messenger design pattern, the most common implementation being the one in the Zend Framework - Zend_Controller_Action_Helper_FlashMessenger

The basic idea is

• Pop a message onto a stack in session
• Redirect
• Display all messages on the stack
• Clear the stack from session

Answer 2

<?php if (!empty($_GET['favor_trashed'])) : ?>
    <p>Favor has been successfully deleted</p>
<?php endif; ?>
