codeigniter 将多个值插入数据库不起作用

codigniter inserting multiple values to database not working

我有一个简单的 codeigniter 表单,其中有一个如下所示的复选框:

 <th>  <input class="acb" type="checkbox"  name="generateawb[]" value="<?=$val->id?>" onclick="deRequire('acb')" required /></th>
  <button type="submit" name="savemedaa" style="margin-left:5px; font-size: 0.6em; " class="btn btn-warning">GENERATE AWB</button>

所以当用户选择一个或多个复选框时,它应该将所选数据插入另一个 table,我的控制器如下所示:

public function generateawb() {
  $data = array();
    if(isset($_POST['savemedaa']))
    {

      $checkboxs = $_POST['generateawb'];
      $generateawb = $this->excel_import_model->selectawb($checkboxs);

foreach($generateawb as $row){
  $clientid= $row->id;
  $batchnumber= $row->batchnumber;

}
$awbg = random_int(100000000, 999999999);
$awb='LRG'.$awbg;

        $data[] = array(
          'clientid'=>$clientid,
          'awb'=>$awb,
           'batchnumber'=>$batchnumber,

        );

      $this->excel_import_model->generateawb($data);

    }
      }
}

我的模型如下:

    public function selectawb($checkboxs) {
                            $this->db->select('*');
                            $this->db->where_in("id", $checkboxs);
                            $this->db->from('fileupload');
                         $query = $this->db->get();
                         $result = $query->result();
                         return $result;

                        }

                        function generateawb($data){
                            $this->db->insert_batch('consignments', $data);
                        }

现在的问题是,即使用户选择了多个复选框,也只有一个复选框被保存到数据库中,谁能告诉我这里出了什么问题,谢谢

您将 $data[] 放在 foreach 之外,因此它只有一个值。把它放在里面:

public function generateawb()
    {
        $data = array();
        if (isset($_POST['savemedaa'])) {

            $checkboxs = $_POST['generateawb'];
            $generateawb = $this->excel_import_model->selectawb($checkboxs);

            foreach ($generateawb as $row) {
                $clientid = $row->id;
                $batchnumber = $row->batchnumber;
                $awbg = random_int(100000000, 999999999);
                $awb = 'LRG' . $awbg;

                $data[] = array(
                    'clientid' => $clientid,
                    'awb' => $awb,
                    'batchnumber' => $batchnumber,

                );
            }

            $this->excel_import_model->generateawb($data);
        }
    }

您应该使用格式化程序来避免此类错误。如果你使用 VSCode 你可以使用这个 extention
