Hi,

I am pretty new to WFB.

I need to encrypt password before sending it to Mysql.

I am trying to do it by REDIRECT TO ANOTHER URL option and then using PHP to catch the value with
$variable = $_POST['variable'] but is not working.

Any help will be appreciated

You'll need to write your own myformname.php to process the data as the form builder relies on $_SESSIONs to work so they get unset on submission.
On you custom php page you will want to use the md5() function to encrypt the variable.
<?php
$encr_myvariable = "$myvariable_name";
echo md5($encr_myvariable);
?>
