action hook PreModuleCreate

[Sreejit]

I have custom custom field named "documentId" for a product. When a client singup for a service and fills in this field, I want the domain name to be set to this "documentId" value. I tried do this using action hook PreModuleCreate http://docs.whmcs.com/Hooks:Products...reModuleCreate but te below code is not working.

$vars['params']['domain'] = $vars['params']['customfields']['documentId'];

Any idea what I am doing wrong?

You will be best to use the "AfterModuleCreate" hook and then update the db directly like this

update_query("tblhosting",array("domain"=>$vars['params']['customfields']['documentId']),array("id"=>$vars["params"]["serviceid"]));
