Validating Hidden Field

Validating Hidden Field

I have a hidden field within a 'Contact Me' form, to be submitted via Universal email.

I set this field to be the Subject of the email. That way when the email is received, I know from which form it has been sent. I realize that I could set the Subject directly in Universal Email, but I want to use this field as a check to stop bots submitting via my form.

Using validation I'd like to create a rule that checks that the Subject field is as I expect, for example; "Here's your requested link".

How can I set up a validation rule to do this ?

Thanks.

You can create a session variable and set it to the value you want the hidden form element to be and use the like entry server validation to compare the hidden element against the session variable:

Go to the bindings panel. Click the plus button and select "Session Variable". Name the session variable "Subject".


On you page add the following code at line 1 to set the session variable:

php:
<?php

if (!session_id()) session_start();
$_SESSION['Subject'] = "Here's your requested link";
?>



In the server validation wizard, select the hidden form element, and select the Like Entry validation type, when you click the plus button to add it, select the Subject session variable.
