Email Notifications - encode / obfuscate merge tag values

    I am including in the notification email template, a link with a couple of parameters built using merge tags.

    eg. http://domain.com/page.php?a={merge tag}&b= ......

    Is there a way to encode / obfuscate the parameters values? I tried using base64_encode({merge tag}) but realised php is not processed in the notification template.

    Your best bet would be to have hidden fields in your form, and use our pre_submission hook to grab the submitted values, obfuscate them, and then push them to your hidden fields. Then you would be able to grab them with a normal merge tag.

    Hi David, thanks for pointing me to the right direction, have got things setup nicely following your tips.

    Finally, how to I prevent those hidden fields (which holds the obfuscated values) from showing up in email notifications?

    For that, you would have to build out your notification manually rather than using the {all_fields} tag.

    Isn't there the {all_fields:nohidden} merge tag to prevent hidden fields from showing up in emails?

    There is, but it depends on how the field was hidden. If he used CSS/JS to hide the field versus the hidden field type, then it will still show in the notifications. See all of our Merge Tag details here: http://www.gravityhelp.com/documentation/page/Merge_Tags
