Thanks Upon change of Dropdown A I have an ajax function request tha re-populated Downdown B with the filtered options based on the selection in Dropdown A. See the ajax jquery script... <pre><code>[php] countryFilter = function () { var countryClass = '.dealer-country select', dealerClass = '.dealer-name select'; $(countryClass).change(function(){ var countrySelect = $(this), country = countrySelect.val(), dealerSelect = countrySelect.parents('form').find(dealerClass); if(country != "default") { $.ajax({ type: 'POST', url: '<?php echo admin_url('admin-ajax.php'); ?>', data: { dealerCountry : country, action: 'get_dealer_name' }, success: function(data){ dealerSelect.empty(); var options = $.parseJSON(data); for(i=0;i<options.length;i++){ dealerSelect.append('<option value="'+options[i].value+'">'+options[i].text+'</option>'); } dealerSelect.removeAttr('disabled'); } }); } }); }</code></pre> Which I fired using... <pre><code>[js] $(document).ready(function () { countryFilter(); }); $(document).bind('gform_post_render', function(event, form_id){ if(form_id == 3) { countryFilter(); } });</code></pre> I then trimmed my original functions to... <pre><code>[php] // Dropdown A - Dealer Country add_filter("gform_pre_render", "dropdown_dealer_country"); add_filter("gform_admin_pre_render", "dropdown_dealer_country"); function dropdown_dealer_country($form){ if($form["id"] != 3) return $form; $terms = get_terms("dealer-country"); $items = array(); $items[] = array( "text" => __('Select country...','theme'), "value" => 'default' ); foreach($terms as $term) $items[] = array( "text" => $term->name, "value" => $term->slug ); foreach($form["fields"] as &$field){ if($field["id"] == 6 ){ $field["cssClass"] = 'dealer-country'; $field["choices"] = $items; } } return $form; } // Dropdown B - Dealer Name add_filter("gform_pre_render", "dropdown_dealer_name"); add_filter("gform_admin_pre_render", "dropdown_dealer_name"); function dropdown_dealer_name($form){ if($form["id"] != 3) return $form; $items = array(); $items[] = array( "text" => __('Select dealer...','theme'), "value" => 'default' ); foreach($form["fields"] as &$field){ if($field["id"] == 7){ $field["cssClass"] = 'dealer-name'; $field["choices"] = $items; } } return $form; }</code></pre> Then the finishing touch is the function which also goes in the functions.php - this is called by the ajax request... <pre><code>[php] function get_dealer_name_fn(){ $dealerCountry = $_POST['dealerCountry']; $dealers = get_posts(array( "post_type" => "dealer", "dealer-country" => $dealerCountry, "post_status" => "publish", "orderby" => "title", "order" => "ASC", "posts_per_page" => -1 )); $items = array(); $items[] = array( "text" => __('Select dealer...','theme'), "value" => 'default' ); foreach($dealers as $dealer){ $items[] = array( "text" => $dealer->post_title, "value" => $dealer->post_title ); } echo json_encode($items); die; } add_action('wp_ajax_get_dealer_name', 'get_dealer_name_fn'); add_action('wp_ajax_nopriv_get_dealer_name', 'get_dealer_name_fn');</code></pre> David Peralty on "gform_pre_render upon previous dropdown condition?" https://legacy.forums.gravityhelp.com/topic/gform_pre_render-upon-previous-dropdown-condition#post-134261 Mon, 28 Jan 2013 17:48:13 +0000 David Peralty 134261@https://legacy.forums.gravityhelp.com/ You would have to use JavaScript (AJAX) to do this, by capturing the choice and doing stuff to it and changing your second drop down.

I have dealer form. Which basically you choose your county, and then your dealer. Dropdown A = Dealer Country Dropdown B = Dealer Name I have about 15 countries, and I am using get_terms in the gform_pre_render to list all my countries that I have assigned to a dealer... <pre><code>// Dropdown A - Dealer Country add_filter("gform_pre_render", "dropdown_dealer_country"); add_filter("gform_admin_pre_render", "dropdown_dealer_country"); function dropdown_dealer_country($form){ if($form["id"] != 3) return $form; $terms = get_terms("dealer-country"); $items = array(); $items[] = array( "text" => __('Select country...','mission-theme'), "value" => 0 ); foreach($terms as $term) $items[] = array( "text" => $term->name, "value" => $term->slug ); foreach($form["fields"] as &$field) if($field["id"] == 6){ $field["choices"] = $items; } return $form; }</code></pre> OK so the above works perfectly in Dropdown A Now what I am trying to do in Dropdown B is display all my dealer names. I have named each dealer custom post-type title with the name of the dealer, and this is what I am pre populating my secondary drop down with... <pre><code>// Dropdown B - Dealer Name add_filter("gform_pre_render", "dropdown_dealer_name"); add_filter("gform_admin_pre_render", "dropdown_dealer_name"); function dropdown_dealer_name($form){ if($form["id"] != 3) return $form; $dealers = get_posts(array( "post_type" => "dealer", "dealer-country" => $dealerCounty, "post_status" => "publish", "orderby" => "title", "order" => "ASC", "posts_per_page" => -1 )); $items = array(); $items[] = array( "text" => __('Select dealer...''mission-theme'), "value" => 0 ); foreach($dealers as $dealer) $items[] = array( "text" => $dealer->post_title, "value" => $dealer->post_name ); foreach($form["fields"] as &$field) if($field["id"] == 7){ $field["choices"] = $items; } return $form; }</code></pre> ...and as you can see in line 11, I have a variable in my get_posts array <code>"dealer-country" => $dealerCounty</code> My question, is it some how posible to get the choice that is made in Dropdown A into my <code>$dealerCounty</code> variable in my Dropdown B function? Any tips or help would be much appreciated as my Dropdown B is currently very long, and I need to filter it down by country. Many Thanks Josh
