javascript - Cannot get the dependent dropdown value from region dropdown -

the picture

in process, did modifications controller, view, including controller. in pic below :

error message

i got error message below :

syntaxerror: unexpected token < ok <br /> <b>fatal error</b>: phone call fellow member function getgeozonesbyzoneid() on non-object in <b> /home/........../catalog/controller/account/register.php </b> on line <b>513</b><br /> the code

in ../controller/account/register.php, added modifications below :

public function zone() { $json = array(); $this->load->model('localisation/zone'); $geozone_info = $this->model_localisation_zone->getzone($this->request->get['zone_id']); if($geozone_info) { $this->load->model('localisation/geo_zone'); $json = array( 'country_id' => $geozone_info['country_id'], 'name' => $geozone_info['name'], 'code' => $geozone_info['code'], 'zone' => $geozone_info['zone_id'], 'geozone' => $this->model_localisation_geozone->getgeozonesbyzoneid($this->request->get['zone_id']), 'status' => $geozone_info['status'] ); } $this->response->setoutput(json_encode($json)); }

line 513 :

'geozone' => $this->model_localisation_geozone->getgeozonesbyzoneid($this->request->get['zone_id'])

i don't know what's wrong getgeozonesbyzoneid function, because think write function correctly in ../model/localisation/geo_zone.php below :

<?php class modellocalisationgeozone extends model { public function getgeozone($zone_id) { $query = $this->db->query("select * " . db_prefix . "geo_zone geo_zone_id = '" . (int)$geo_zone_id . "'"); homecoming $query->row; } public function getgeozonesbyzoneid($zone_id) { $geozone_data = $this->cache->get('geozone.' . (int)$zone_id); if (!$geozone_data) { $query = $this->db->query("select * " . db_prefix . "zone_to_geo_zone zone_id = '" . (int)$zone_id . "'"); $geozone_data = $query->rows; $this->cache->set('geozone.' . (int)$zone_id, $geozone_data); } homecoming $geozone_data; } } ?>

and added javascript register.tpl in view below :

$('select[name=\'zone_id\']').bind('change', function(event, first_time) { $.ajax({ url: 'index.php?route=account/register/zone&zone_id=' + this.value, datatype: 'json', beforesend: function() { $('select[name=\'zone_id\']').after('<span class="wait">&nbsp;<img src="catalog/view/theme/default/image/loading.gif" alt="" /></span>'); }, complete: function() { $('.wait').remove(); }, success: function(json) { var html = '<option value=""><?php echo $text_select; ?></option>'; var selected = false; if (json['geozone'] && json['geozone'] != '') { (i = 0; < json['geozone'].length; i++) { html += '<option value="' + json['geozone'][i]['geo_zone_id'] + '"'; if (json['geozone'][i]['geo_zone_id'] == '<?php echo $geo_zone_id; ?>') { html += ' selected="selected"'; selected = true; } html += '>' + json['geozone'][i]['name'] + '</option>'; } } else { html += '<option value="0" selected="selected"><?php echo $text_none; ?></option>'; } $('select[name=\'geo_zone_id\']').html(html); if(typeof first_time === "undefined" && selected) { $("#register_details_form").validate().element('#register_details_form select[name="geo_zone_id"]'); } }, error: function(xhr, ajaxoptions, thrownerror) { alert(thrownerror + "\r\n" + xhr.statustext + "\r\n" + xhr.responsetext); } }); }); $('select[name=\'zone_id\']').trigger('change', ['first_time']);

anyone can help me resolve issue? or maybe have same experiences me , willing share solutions me?

thanks before in advance.

use model_localisation_zone (defined variable) instead of model_localisation_geozone (not defined), or create sure latter defined.
