There is an API hook called gform_validation that you can use to write your own custom validation for a field. You can find documentation for this hook here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a></p> <p>There is also a tutorial on how to write custom validation in a tutorial here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_valiation%22_Hook" rel="nofollow">http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_valiation%22_Hook</a></p> <p>We can't take into account all kinds of custom use validation which is why we have a hook that allows developers to write their own custom validation for custom use cases. </p> https://legacy.forums.gravityhelp.com/topic/excluding-keywords-for-field-population#post-26238 Tue, 24 May 2011 15:04:56 +0000 LW 26238@https://legacy.forums.gravityhelp.com/ <p>Is there a way in the form to enter a couple keywords that exclude the user from filling in that certain keyword that's excluded? Say I ask a question in the form that states: Where did you hear about us? And they type in, "internet". Is there a way to stop that keyword from being entered? Or if not, any future thought on implementing this? </p>
