I have multiple sections on one form that are all identical but only show up (i.e., are conditional fields) when a user clicks "Add another property". I'd like these new property fields to autopopulate with the info put in for the previous property. I've read around a bit, but I'm definitely a rookie when it comes to editing PHP or figuring out where to post the code snippets I've seen and how to properly format them. Any help would be great. </p> https://legacy.forums.gravityhelp.com/topic/how-to-prepolute-a-field-based-on-a-previous-field-in-the-same-form#post-67251 Fri, 20 Jul 2012 12:48:55 +0000 redkite 67251@https://legacy.forums.gravityhelp.com/ <p>I've been looking around in the forums for a while and am using the code snippet from this post:</p> <p><a href="http://www.gravityhelp.com/forums/topic/populate-field-from-previous-field" rel="nofollow">http://www.gravityhelp.com/forums/topic/populate-field-from-previous-field</a></p> <p>This is my version of the code from functions.php, but it's not working:</p> <pre><code>// update &quot;108&quot; to the ID of your form add_filter(&quot;gform_pre_render_2&quot;, &quot;populate_previous_page_data&quot;); function populate_previous_page_data($form){ $page_number = rgpost(&quot;gform_target_page_number_{$form[&quot;id&quot;]}&quot;); $page_number = !is_numeric($page_number) ? 1 : $page_number; foreach($form[&#39;fields&#39;] as &amp;$field) { if($field[&#39;id&#39;] != 42.5) // update &quot;15&quot; to the ID of the field you wish to be populated; $field_page = rgar($field, &#39;pageNumber&#39;); if($page_number &gt; $field_page) continue; // update this to the ID of the field whose value you wish to call // &#39;16.3&#39; = example, first name of a Name field // &#39;16.6&#39; = example, last name of a Name field $field[&#39;defaultValue&#39;] = rgpost(&#39;1&#39;); } return $form; }</code></pre> <p>My form is here, and I'm trying to prepopulate the Zip code field on the last page with the value entered on the first page.
