Human Test Question : Pre-Parser Code not working ?

[ITZAP]

Also, it doesn't appear that the form_tools_ignore_submission key works for this particular form. We can't narrow down the particular issue.

So instead, you can just change the rule to this:

if (isset($_POST["htest"]) && $_POST["htest"] != "16") {
header("location: http://www.google.com");
exit;
}

For the other requests please be aware that the pre-parser rules will fire every time the user goes from one page to the other. Accordingly, checking that $_POST has the desired key in it is paramount, otherwise it will fire all the time. Checking for the existence of a key will ensure it only fires on a single page.

Thanks Joe, that "exit with redirect" method does work.
But for the other functions I need, like prevent Blank submissions if form abandoned and end total calculation, looks like I need to design an External Form pointed to process.php, rather than use the "Form Builder" module.
Your assistance and support much appreciated.
Gary, ITZAP.
