Use the *gform_field_validation* hook:<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_validation</a></p> <p>Here is some example code to put in your *functions.php* file:<br /> <a href="http://pastebin.com/fUbgVqbh" rel="nofollow">http://pastebin.com/fUbgVqbh</a> </p> https://legacy.forums.gravityhelp.com/topic/simple-form-validation#post-168036 Mon, 11 Mar 2013 16:05:06 +0000 helicon 168036@https://legacy.forums.gravityhelp.com/ <p>Hello, I'm trying to find a very easy way of validating a discount code on my site. It won't need to be a required field (as most users won't have a code), but I do need the user to enter the correct code otherwise it should say "invalid code". At the moment I am only using one code but I may need to use more in the future.</p> <p>I'm not that great at PHP so am hoping there is a simple solution out there!</p> <p>Many thanks. </p>
