It is best for you to post your own topic in the future, especially since this is an old post that I wasn't actively checking.</p> <p>For the checkbox that you are trying to check based on what link was clicked upon, you should use the querystring parameter. Go to the Advanced tab for your checkbox field in the admin and check the "Allow field to be populated dynamically" option. When you check that option off a text box will appear called "Parameter name". This is where you would put the name of your querystring parameter. In your example, you appear to be passing the parameter as formtype, so you would use that.</p> <p>If you want fields to display depending on what link was clicked, you can add conditional logic to those fields in the admin on the Advanced tab and key those off of your checkbox field. If I am understanding you correctly, you should be able to do all this without custom code and without using any Gravity Forms hooks; do it all in the admin. </p> https://legacy.forums.gravityhelp.com/topic/use-conditional-logic-on-dynamically-populated-field#post-54002 Mon, 02 Apr 2012 12:21:54 +0000 anndonnelly 54002@https://legacy.forums.gravityhelp.com/ <p>I'm not sure about how/where to use gform_admin_pre_render. My form is at <a href="http://gwa.thewildlifefilmschool.com/contact-us/" rel="nofollow">http://gwa.thewildlifefilmschool.com/contact-us/</a>. I want it so that depending on which link a user clicks it populates the first question (ie <a href="http://gwa.thewildlifefilmschool.com/contact-us/?formtype=subscribe)" rel="nofollow">http://gwa.thewildlifefilmschool.com/contact-us/?formtype=subscribe)</a>. Using conditional logic to show specific fields depending on which field is ticked. They user can then tick additional boxes if needed to show more fields.

That way you will have your options available for use with conditional logic. </p> https://legacy.forums.gravityhelp.com/topic/use-conditional-logic-on-dynamically-populated-field#post-47326 Wed, 25 Jan 2012 11:49:11 +0000 newhorn 47326@https://legacy.forums.gravityhelp.com/ <p>I have a drop down that I populate dynamically. What I would like to do is set some conditional logic based on the chosen item in the drop down. The problem is I can't use the normal conditional logic since the field is populated dynamically.</p> <p>So I was wondering if there was someone to manually create the conditional logic after the field has been dynamically populated? The drop down populates with event names and the value of each is a date. What I want to do is show or hide fields based on that date. This would be easy enough if the field was manually created in the backend, but the dynamic population is making this harder then it should be.</p> <p>What I have done now is wrote some custom javascript to get the value of the drop down and add or remove classes on other field items, in order to show or hide them. This works but it would be nicer to keep it all in gravity forms. </p>
