   Hi all,

   I am looking to use MachForm for my field validation, but I also have additional application validation that needs to occur.

   Here are 2 examples:

   1) My user enters an email address. I will have MachForm check for duplicates, but I also need to be able to check the primary database to determine if the email address already exists. This would indicate that the user has already registered, so I need to throw an error. I would like that error to come up just as the errors do for field validation, but with a different message. So, the error would say 'That email address is already taken. Please enter a new email address.'.

   2) My user enters a value they want to use for an application. I have Perl scripts that go and evaluate that code. It is easy enough to call Perl from PHP, but where do I insert it, and how do I get the result of that call to be used in the PHP scripts to flag an error.

   In other words, they type in the word 'cat'. I check inventory, and we have no cats. So, I throw an error saying 'Parameter cat is unknown. Please re-enter.'

   I have a ton of functionality in Perl that I would like to keep, and I want the user to stay on the same form until I have validated everything and written the data to my primary database for the application, which again is no problem through my Perl scripts. But, where do I put the call to the Perl scripts, and how can I add the error messages back to the JS error handling?

   Thank all, I really appreciate the help.

   I must say this one pretty hard to explain, since the backend processing is pretty complex.

   Basically you'll need to modify one file "includes/post-functions.php" file.
   Inside the file, there is the main form processing function "process_form()" which handle all form validations and submission.

   You'll need to dig into this function and play around to get clear understanding with the code.

   Sorry if I can't be more helpful!
