I wonder if anyone has had success with this.
I am also trying to figure out how to use Security Assist rules manager and Show If to pass validation on successful form submit.
I have created my rule value: <?php echo ((isset($_POST))?"1":""); ?> and set the Criteria to <>
I then applied this validation rule to my region as a Show Region
However it looks like the validation is always in a state of 'Pass'. My region appears even before the form is submitted.
Any assistance or clarification would be appreciated.
