You can achieve this using the gform_pre_render hook, which I would never have thought to use as the price is built on the second form page based on activity from the first form page. However, here's the working code:</p> <p><a href="http://pastie.org/5341905" rel="nofollow">http://pastie.org/5341905</a> </p> https://legacy.forums.gravityhelp.com/topic/dynamically-populating-price-with-gform_post_paging#post-79992 Wed, 10 Oct 2012 06:26:30 +0000 theslink2000 79992@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>I've been trying to build an order form based around dynamic selection of a patients medications. I've got all the code working behind the scenes so far, however I can't seem to get it to populate the price field.</p> <p>I'm using a multi-page form where the first page is dynamically populated with a patients medications from the database as checkboxes likes this:</p> <p><a href="http://pastie.org/5028907" rel="nofollow">http://pastie.org/5028907</a></p> <p>Then on the second page it checks to see how many checkboxes have been ticked and then multiplies that by a preset prescription charge. The only way I've found of doing this is using the gform_post_paging hook as the basic gform_field_value hook outputs $_POST data multiple times for some reason. When I dump the information (seen in the order_prescription_cost function) it prints all the correct information as floats, however the gform_post_paging hook won't update the price field. Here's the code:</p> <p><a href="http://pastie.org/5028929" rel="nofollow">http://pastie.org/5028929</a></p> <p>I can't understand it, I've found a thread on here (<a href="http://www.gravityhelp.com/forums/topic/dynamic-population-parameter-outputs-outside-the-form-but-not-in-form-fields#post-64752" rel="nofollow">http://www.gravityhelp.com/forums/topic/dynamic-population-parameter-outputs-outside-the-form-but-not-in-form-fields#post-64752</a>) that states the gform_post_paging hook can be used like gform_pre_render, but it's not responding at all.</p> <p>Can someone please help! </p>
