Without knowing what field IDs you are using, it's hard to give you the code to do this. However, you would use the gform_validation hook to compare all the values, and return a validation error after the form is submitted, if the amounts exceed the commission balance.</p> <p><a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a> </p> https://legacy.forums.gravityhelp.com/topic/custom-form-validation#post-154622 Tue, 26 Feb 2013 00:24:05 +0000 visions 154622@https://legacy.forums.gravityhelp.com/ <p>Hello</p> <p>I have a site where users earn commissions through referral of ad placements<br /> Once their commission gets up to $25 they can choose to redeem their commission through issuance of gift vouchers. </p> <p>I'm using Gravity forms for them to fill out a form to request to redeem their commission.</p> <p>In the form they can select 2 stores that they want a gift voucher for and then enter the value they want to spend in each store.</p> <p>The problem is that I need to validate the form so the total amount of these 2 fields is not greater than their total commission balance which is passed to the form through a $_GET value.</p> <p>eg. If my commission balance is $40.00, then the combined total of the 2 fields can't be more than 40</p> <p>I am embedding my form into a page template using do_shortcode</p> <p>echo do_shortcode(" [gravityforms id=7 title='false' description='false' field_values='commission_value=".$_GET['balance'].");</p> <p>Can you give any advice on how I can hook into the form validation to validate these fields? </p>
