Answer 1

尝试这个

if(isset($this->session->data['payment_address']['zone'])){
  $data['zone'] = $this->session->data['payment_address']['zone'];
}else{
  $data['zone'] = '';
}

Answer 2

检查$ data ['zone_id']是否正在接收某些值

echo“<pre>”; 的print_r（$数据[ 'zone_id']）;模具;

如果$ data ['zone_id']为空则检查此$this->session->data['guest']['payment']['zone_id'];

要么

如果$data['zone_id']正在接收值，则添加此值

if (isset($this->session->data['guest']['payment']['zone_id'])) {
            $data['zone_id'] = $this->session->data['guest']['payment']['zone_id'];         
        } else {
            $data['zone_id'] = '';
        }
        $this->load->model('localisation/zone');

        $zone_info = $this->model_localisation_zone->getZone($data['zone_id']);

$zone_info['name'] = isset($zone_info['name'])?$zone_info['name']:'';

        $data['zone'] = $zone_info['name'];
