I've put together a rule that sends an email on a create node for a specific content type and this is working correctly.
However, I would like to prevent the standard message for a node create being displayed and set one of my own.
I've tried adding an action to "Execute custom PHP code" with the following in it:
<?php
drupal_get_messages('');
drupal_set_message('My message in here','');
?>The result is that my message is displayed as well as the standard create node message in the form " has been created."
I thought that the drupal_get_messages(''); would clear any existing messages, but this isn't happening.
Could anyone help me out on this? Why would drupal_get_messages(''); not be working as I think it should? Should I be taking a different approach to stopping the system message being displayed?
Any suggestions on this would be much appreciated.
