<p>This plugin allows you to use $_COOKIE, $_SERVER, $_SESSION, $_GET, $_POST and $_REQUEST data in a Gravity Form through the merge tags of a field. I’ve only really tested this using a hidden field.</p>


Gravity Forms Extended Merge Tags

It's amazing how few people seem to know about this plugin. Incredibly simple, but also really helpful when using $_SESSION variables to track website visitors.
I use it to get referring website data, so I can easily store it in a $__SESSION variable. Then when the visitor fills out a Gravity Form, I can pass along the stored vars.
I crafted a Lead Source Tracking for Salesforce script that uses this plugin to pass along the details to Salesforce when a form is submitted.

<p>Limiting the cookie expire time of password protected posts. By default the cookie set when entering a password to access a password-protected post will be active for 10 days. This plugin turns this cookie into a session-based cookie. This means your visitor will need to re-enter the password if the browser was closed prior to revisiting the post.</p>


Instant Cookie Expire

This plugin turns the cookie for a password-protected post into a session-based cookie.
