form表单应该包住所有input输入

提前到input开始之前的地方即可

用post接受的，可是没看到password的表单，代码没贴全？？

改为这样就可以了。

<form name="form2" method="post" action="login.php"><p><span class="top-head">密 码 ：</span>    <label for="password"></label>  <input name="password" type="text" id="password" value="请输入密码">  </p>
                    <div class="aritcle_card">
                        <a class="aritcle_card_img" href="/ai/2085">
