在警报中打印变量

Question

我有这个模型功能来计算用户数量

public function get_employee_list($role_id) {
    $qStr = "SELECT
              count(admins.id)
             FROM
              admins
             WHERE
              admin_role=".$role_id;
              $query = $this->db->query($qStr);

    return    $query->row_array();

  }

我的控制器功能是这样的

 public function delete_employee_role_ajax($role_id) {
        $objResponse = new xajaxResponse();
        $response = $this->employee_model->get_employee_list($role_id);
        //print_r($response);
        if($response) {
            $objResponse->script( "bootbox.alert('$response +users are associated with this role and it cannot be deleted')" );
        }
        else {
        $response = $this->employee_model->delete_employee_role($role_id);
        $objResponse->script( "window.location.reload()" );
        }
        return $objRespons

}

我想打印$ response的值。

您可以尝试将其编码为JSON结构 ：

$encodedResponse = json_encode($response);
$objResponse->script("bootbox.alert('$encodedResponse +users are associated...')" );
