"gform_pre_submission_filter_1" You also have to modify the "inputs" array for it to work though.</p> <pre><code>add_filter(&quot;gform_admin_pre_render&quot;, &quot;amenities&quot;); add_filter(&quot;gform_pre_submission_filter_1&quot;, &quot;amenities&quot;); add_filter(&#39;gform_pre_render_1&#39;, &#39;amenities&#39;); function amenities($form){ $amenities = get_categories(array(&#39;child_of&#39; =&gt; 15, &#39;order_by&#39; =&gt; &#39;name&#39;, &#39;hide_empty&#39; =&gt; 0)); $amenities_choices = array(); $amenities_inputs = array(); $i = 1; foreach ($amenities as $amenity) { $amenities_choices[] = array(&#39;text&#39; =&gt; $amenity-&gt;name, &#39;value&#39; =&gt; $amenity-&gt;term_id); $amenities_inputs[] = array(&#39;id&#39; =&gt; &#39;12.&#39;.$i, &#39;label&#39; =&gt; $amenity-&gt;name, &#39;name&#39; =&gt; &#39;&#39;); $i++; } foreach($form[&#39;fields&#39;] as &amp;$field) { if($field[&#39;id&#39;] == 12) { $field[&#39;choices&#39;] = $amenities_choices; $field[&#39;inputs&#39;] = $amenities_inputs; } } //ri_echo($form); return $form; }</code></pre> https://legacy.forums.gravityhelp.com/topic/gform_pre_render-and-multiselect#post-72312 Thu, 23 Aug 2012 12:53:54 +0000 Brian 72312@https://legacy.forums.gravityhelp.com/ <p>I am generating a multiselect field based on subcategories.<br /> <pre><code>add_filter(&#39;gform_pre_render_1&#39;, &#39;amenities&#39;); function amenities($form){ $amenities = get_categories(array(&#39;child_of&#39; =&gt; 15, &#39;order_by&#39; =&gt; &#39;name&#39;, &#39;hide_empty&#39; =&gt; 0)); $amenities_choices = array(); foreach ($amenities as $amenity) { $amenities_choices[] = array(&#39;text&#39; =&gt; $amenity-&gt;name, &#39;value&#39; =&gt; $amenity-&gt;term_id); } foreach($form[&#39;fields&#39;] as &amp;$field) { if($field[&#39;id&#39;] == 12) { $field[&#39;choices&#39;] = $amenities_choices; } } return $form; }</code></pre> <p>This works great. The problem is that on the creation of the form, I only have one "item" on the multiselect. So when processing Gforms only checks for one. I am looking for something that can be adjusted via a filter so it will process numbers based on the newly generated multiselect options. </p>
