防止表單提交重定向

我最近（有一點幫助）將這種簡單的表單寫入電子郵件腳本。它的工作原理，唯一的問題是它運行時重定向到包含的php腳本。有沒有人有關於如何阻止這種情況發生的想法，而只是在原始頁面上顯示感謝信？防止表單提交重定向

的index.php

您需要設置形式定位到文件itselfe。

<form name="email" method="post" action="form.php">

幷包含您的代碼從email.php那裏。

if ($_POST['email']) { 
    ... code from email.php ... 
    ... and success message ... 
}

只有在表單被髮送（並設置了電子郵件）時纔會執行此部分。

改變你的表單標籤說：

<form name="email" method="post" action="index.php">

，改變你的指數PHP說：

<body> 
<?php 
    if (isset($_POST['email'])) { 
     include 'email.php'; 
    } else { 
     include 'form.php'; 
    } 
?> 
</body>

因此，如果表單被提交，發送電子郵件，否則，顯示窗體。

你可以回重定向直接從form.php的

將這個在form.php的

header("url: index.php");

甚至結束：

header("url: index.php?sent=true");

而且在index.php中你可以有

if($_GET['sent']){ 
    echo "Message Sent."; 
}
