</form></td>

以下是cc.php的代码

cc.php

<?php 
if(($_POST['check']) == $_SESSION['check']) { 
echo 'Input OK';
}else{ 
echo 'Input Wrong';        
}

Answer 1

<form>中有<form>。摆脱内部形式标签，事情应该很好。

Answer 2

因为POST和SESSION 检查都是空的

使用

var_dump($_POST['check']);

和

var_dump($_SESSION['check']);

检查其值和类型

验证码代码出错
