I believe I understand that I need replace "date" in the example code on that page so it looks like this:</p> <pre><code>&lt;?php add_filter(&quot;gform_field_value_url&quot;, &quot;populate_url&quot;); function populate_url($value){ return &quot;10/10/2010&quot;; } ?&gt;</code></pre> <p>But I'm not sure what I would put in </p> <pre><code>$value</code></pre> <p>or </p> <pre><code>return &quot;10/10/2010&quot;;</code></pre> https://legacy.forums.gravityhelp.com/topic/outputting-a-php-echo-in-a-hidden-field#post-162243 Wed, 06 Mar 2013 16:19:17 +0000 David Peralty 162243@https://legacy.forums.gravityhelp.com/ <p>Have a look at this hook: <a href="http://www.gravityhelp.com/documentation/page/Gform_field_value_$parameter_name" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_value_$parameter_name</a></p> <p>You'll want to put any PHP code in the theme's functions.php file.
