[Vtigercrm-developers] aborting a save in an event handler

[Alan Bell]

Hi all,

I have a situation where we want to do a 
vtiger.entity.beforesave.modifiable event handler for a SalesOrder This 
will do some validation based on a bunch of queries to the database 
based on fields in the $entitydata that gets submitted. If the 
validation fails and the user isn't allowed to save this order it should 
fail, and take them back to the form so they can fix whatever the 
problem was and try again.
The problem is that the sales order does not have a crmid yet, it has 
not been saved. I can't do the tests on the client side before the form 
is submitted and I can't do a history.back() because the browser won't 
let me go back through the submit, I get a Document Expired error message.

I can do a die("error message"); which will abort the save and returns 
the error message as text to the browser, but this is a bit ugly, and 
doesn't help the user get back to the form they came from.

Any suggestions on how to do a graceful abort of a save during the event 
handler?

Alan.
