控制器中

session_start();
$code =mt_rand(0,1000000);
$_SESSION['code'] = $code;
$this->assign('code',$code);

注：該段程式碼應在表單提交判斷的後面

往html中傳一個session隨機數，並把該隨機數用隱藏input框的形式傳值

html頁面中

<input type="hidden" name="hiddenCode" value="<{$code}>">

在表單提交後的做判斷，若input值與session中的值相等，則可繼續提交，否則不執行提交表單

session_start();
        if
 
(isset($data['hiddenCode'])){
          if($data['hiddenCode'] == $_SESSION['code']){
            unset($data['hiddenCode']);
            //提交操作
          }
        }

完整程式碼：

   public function test(){
        $data = I('post.');
        if($data != null){
          $this->addSubmitform($data);
        }
        session_start();
        $code
 
 = mt_rand(0,1000000);
        $_SESSION['code'] = $code;
        $this->assign('code',$code);
        $this->display('.html');
    }
    public function addSubmitform($data){
        session_start();
        if(isset($data['hiddenCode'])){
          if($data['hiddenCode'] == $_SESSION['code']){
            unset
 
($data['hiddenCode']);
            $res1 = M('tableName')->add($data);
            if ($res1 == '') {
              //上傳失敗
              return false;
            }
          }
        }
    }

    <form class="ticket-form" action="" method="post">
       Landing Page<input class="form-input page" type="text" name="page"/>
       <input type="hidden" name="hiddenCode" value="<{$code}>">
       <input  type="submit" value="Submit"  >
    </form>
