Question

我正在尝试使用CodeIgniter执行以下查询，但我正在

未知的索引 - ＆gt; row ['code'];

public function getSExtension($id) {
  $temp = array();
  $query = $this->db->query("SELECT extension_id FROM " . DB_PREFIX . "zipcode_shipping WHERE `zip_code` = '" . $id . "'");
  if($query->num_rows) {
    foreach ($query->rows as $key => $value) {
      $code = $this->db->query("SELECT code FROM " . DB_PREFIX . "extension WHERE `extension_id` = '" . $value['extension_id'] . "'")->row['code'];
      $this->language->load("shipping/".$code);
      $temp[] = $this->language->get('text_title');
    }
  }
  return $temp;
}

问题是您没有正确检索需要方法调用的结果集。如你所知，你试图使用不存在的db属性，即$query->rows应该是$query->row_array()。

在下面的示例中，我使用result()和row()代替任何“数组”方法。

试试这个。

$temp = array();
$query = $this->db->query("SELECT extension_id FROM ".DB_PREFIX."zipcode_shipping WHERE `zip_code` = '".$id."'");

if($query->num_rows() > 0)
{
    foreach($query->result() as $value)
    {
        $code = $this->db->query("SELECT code FROM ".DB_PREFIX."extension WHERE `extension_id` = '".$value->extension_id."'")->row()->code;
        $this->language->load("shipping/".$code);
        $temp[] = $this->language->get('text_title');
    }
}

Codeigniter this-＆gt; db-＆gt;查询未识别的索引
