There is a tutorial on the gform_validation hook here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_validation%22_Hook" rel="nofollow">http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_validation%22_Hook</a></p> <p>That tutorial isn't specific to this implementation, it's merely a tutorial with an example on how to use the gform_validation hook to implement custom validation. You would have to write custom code specific to your validation use case.</p> <p>Your custom code would go in your themes functions.php file or you would create a custom plugin using your code and then activate it on your site. </p> https://legacy.forums.gravityhelp.com/topic/require-one-of-two-fields#post-42328 Mon, 28 Nov 2011 17:17:05 +0000 asiri 42328@https://legacy.forums.gravityhelp.com/ <p>Did you figure out how to do this?

It would be nice to have conditional logic that would require an entry on at least one field in a specified set of fields. </p>
