表单提交后重定向用户

Question

I have a PHP page with a form and after the user completes the form I would like to redirect them to a new page where they can decide their next action.

我看到的建议涉及更改 Form Action，但是我的代码已经有一个 <?php $_PHP_SELF ?> 的操作。我是 PHP 的新手，所以也许我可以用 PHP_Self?

之外的其他方法提交表单数据

下面的代码，提前感谢您的帮助，也欢迎任何有关简化我的代码的建议

Answer 1

<?php $_PHP_SELF ?> 的意思是当前文件，即包含您的表单的文件在表单提交时被调用。因此，您可以保持不变，然后在页面顶部添加重定向代码，并在提交表单时触发它。请注意，必须在任何其他输出之前调用 header 重定向 - 例如 html。

if ($_SERVER['REQUEST_METHOD'] == 'POST'){
 //add any other checks such as form input values
 header('Location: http://myhost.com/mypage.php');
 exit;
}

或将您的表单操作更改为任何其他。php 您想要加载并处理那里的表单输入。

<form method="post" action="some_other.php" name="interactionForm">

更新：

header() 需要在任何输出之前进行，因此：

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
     //add any other checks such as form input values
     header('Location: http://myhost.com/mypage.php');
     exit;
    }
    ?>
<!DOCTYPE html> <html lang="en" xmlns="http://www.w3.org/1999/xhtml"> 
<head>
<meta charset="utf-8" />
<title>New Interaction</title> <!--Declare CSS and JavaScript-->
<link rel="stylesheet" type="text/css" href="RealtyCRM_Style.css">
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="jquery.resmenu.min.js"></script>
</head>

您还可以更新 php 设置以查看错误。这将具体告诉您您是否在重定向之前输出数据 - 除其他事项外，但这将是您的第一个警告。只需确保在完成后删除 ini_set()

<?php
    ini_set('display_errors', '1');
    if ($_SERVER['REQUEST_METHOD'] == 'POST'){
         //add any other checks such as form input values
         header('Location: http://myhost.com/mypage.php');
     exit;
   }
  ?>
