Just add the CSS class name custom_field_input_20 to your checkbox where input_20 is the name of a hidden field you want to get populated (not the Field Label but actually the name of the field if you view the source code of your form)</p> <pre><code>add_action(&quot;gform_pre_submission_1&quot;, &quot;pre_submission_handler&quot;); function pre_submission_handler($form){ foreach($form[&#39;fields&#39;] as &amp;$field){ if($field[&#39;type&#39;] != &#39;checkbox&#39; || strpos($field[&#39;cssClass&#39;], &#39;custom_field_&#39;) === false) continue; $field_id = $field[&#39;id&#39;]; $custom_field_name = str_replace(&#39;custom_field_&#39;, &#39;&#39;, $field[&#39;cssClass&#39;]); foreach($_POST as $key =&gt; $value){ if(strpos($key, &quot;_{$field_id}_&quot;) === false) continue; $_POST[$custom_field_name] .= $value . &quot;,&quot;; } } return $form; }</code></pre> https://legacy.forums.gravityhelp.com/topic/isselected-checkbox-usage#post-29527 Fri, 08 Jul 2011 17:39:45 +0000 conduitstudios 29527@https://legacy.forums.gravityhelp.com/ <p>I figured it out.... someone owes me a hug.

He is currently traveling so it may take some time for him to respond. Bear in mind this is considered a customization so turnaround may not be as quick as for a standard support request. But he should get to it relatively quickly. </p> https://legacy.forums.gravityhelp.com/topic/isselected-checkbox-usage#post-29507 Fri, 08 Jul 2011 14:23:15 +0000 conduitstudios 29507@https://legacy.forums.gravityhelp.com/ <p>I am having trouble figuring out the proper use of isSelected when it comes to checkboxes. Basically I want to find out if a checkbox has been selected. With the function below I am able to get the text, but I just can't seem to figure out how to detect if it is checked.</p> <pre><code>add_action(&quot;gform_pre_submission_1&quot;, &quot;pre_submission_handler&quot;); function pre_submission_handler($form){ $industry = &quot;&quot;; foreach($form[&#39;fields&#39;] as &amp;$field){ if ($field[&#39;type&#39;] == &#39;checkbox&#39;) { foreach($field[&#39;choices&#39;] as $choice) { $industry .= $choice[&quot;text&quot;] . &quot;,&quot;; $industry .= $choice[&quot;isSelected&quot;] . &quot;,&quot;; } } } $_POST[&quot;input_18&quot;] = $industry; }</code></pre>
