Appreciate you pointing out the above info </p> https://legacy.forums.gravityhelp.com/topic/custom-filter-to-display-a-custom-form-field#post-70892 Mon, 13 Aug 2012 15:25:02 +0000 David Peralty 70892@https://legacy.forums.gravityhelp.com/ <p>Sorry, I don't have any examples beyond the documentation. Look through the gform_pre_render documentation as it might help you better understand what you need to do. </p> https://legacy.forums.gravityhelp.com/topic/custom-filter-to-display-a-custom-form-field#post-70890 Mon, 13 Aug 2012 15:08:46 +0000 Chris 70890@https://legacy.forums.gravityhelp.com/ <p>Thanks! Do you know of a page that has an example of the above being used? I'm not the best with coding but can follow examples and kinda hack it together from there :)</p> <p>Thanks </p> https://legacy.forums.gravityhelp.com/topic/custom-filter-to-display-a-custom-form-field#post-70881 Mon, 13 Aug 2012 14:04:14 +0000 David Peralty 70881@https://legacy.forums.gravityhelp.com/ <p>Here is a hook for grabbing the page change:<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_post_paging" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_post_paging</a></p> <p>That might help you with things. You could copy the value to a hidden field on page two and use conditional logic then to give you what you want. </p> https://legacy.forums.gravityhelp.com/topic/custom-filter-to-display-a-custom-form-field#post-70880 Mon, 13 Aug 2012 14:01:10 +0000 Chris 70880@https://legacy.forums.gravityhelp.com/ <p>I am going to try my best to explain what I am doing.</p> <p>I want to create a two page form.</p> <p>One page one, I am going to have a field for the user to fill out.<br /> One page two I want to dynamically display different options for a field based on the value on page one. I can't use the conditional logic built in based on the type of field that is on page one.</p> <p>Is there a way I can use a custom filter (in functions.php) asking... If value of "input_17_1" = "myvalue" then field on page two (input_17_2) is theseoptions, else theseoptions2.</p> <p>If input_17_1 = myvalue</p> <p>input_17_2 = theseoptions<br /> else<br /> input_17_2 = theseoptions2</p> <p>Hope that makes sense. I have successfully changed confirmation emails based on a selected value but am trying to change field options on a second page based on a value on the first page. </p>
