This is helpful. I should be able to give it a go from here. </p> https://legacy.forums.gravityhelp.com/topic/no-duplicates-combination-from-2-fields#post-55353 Mon, 16 Apr 2012 11:22:28 +0000 David Peralty 55353@https://legacy.forums.gravityhelp.com/ <p>It is definitely possible, but not currently built-in to Gravity Forms. The No Duplicates option only applies to a single field at a time. However, this type of advanced validation can be done by writing custom validation using the gform_validation hook. 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>If you are unable to develop a custom solution for your needs, there are a number of WordPress developers that could implement this for you. </p> https://legacy.forums.gravityhelp.com/topic/no-duplicates-combination-from-2-fields#post-55301 Sun, 15 Apr 2012 14:44:33 +0000 torlowski 55301@https://legacy.forums.gravityhelp.com/ <p>I have a meeting registration form that requires there be no duplicates of a combination of two fields, specifically meeting date and category, so that no 2 people from the same business category can register to attend the same meeting date. Is this possible? How do I do this, other than by creating a separate registration form for each event?</p> <p>Thanks! </p>
