我创建了一个登录表单,该表单应该在发送表单后将用户引导到页面,但它只显示一个空白页面

链接为** http://localhost/Cisu/AccHolder/holderlogin.php

登录表单

<?php 
session_start();
?>

不知道它是否会导致你的问题,但你在php声明之前有一个领先的空间 - 如果你在代码中稍后设置标题请求,这可能会导致php渲染出现问题 - 不能渲染任何字符在标头请求之前。

<?php

您还将表单的操作列为“holderlogin.php”

但是将文件名称列为“Holderlogin.php” - 这在输入代码时可能只是一个错字,但值得检查。

另外 - 您没有为表单列出任何方法,但是正在检查$ _POST数组以检查“提交”。它应该是:

<form method="POST" action="holderlogin.php">

答案 2 :(得分:0)

您正在检查是否已设置requests

但是,在您的表单中,$_POST['Submit']属性为name,并且有额外的空格:

Submit

这可能是问题的原因,因为你说给我显示了一个空白页
