Answer 1

您的代码看起来没问题。 Location头可能会失败，因为2个原因：

1. 脚本yust做befor发送的报头部分的输出（可能是一个错误，或者befor你<?php
2. Location头应该是用户简单的一个看不见的标志与绝对的URL，也许是你的相对路径问题

你可以取代你的位置与头：

$returnurl = "http://".$_SERVER["SERVER_NAME"] 
      . ($_SERVER["SERVER_PORT"]!=80?":".$_SERVER["SERVER_PORT"]:"") 
      . dirname($_SERVER["PHP_SELF"]) . "/" 
      . $returnpage; 
header("Location: " . $returnurl); 

而为了让成功和输入错误之间的差别更好，你不需经过你的脚本改为：

<? 
/* Edit these preferences to suit your needs */ 

    $mailto = 'marketing@loanro.co.za'; // insert the email address you want the form sent to 
    $returnpage = '../thanks.php'; // insert the name of the page/location you want the user to be returned to 
    $sitename = '[Loanro]'; // insert the site name here, it will appear in the subject of your email 

/* Do not edit below this line unless you know what you're doing */ 

    $name = $_POST['name']; 
    $email = $_POST['email'] ; 
    $referals = stripslashes($_POST['referals']); 

    $errors = array(); 
    if (!$name)  $errors[] = "Please provide your name."; 
    if (!$email)  $errors[] = "Please provide an email address."; 
    if (!$referals) $errors[] = "Please provide your enquiry details."; 
    if (!eregi("^[a-z0-9]+([-_\.]?[a-z0-9])+@[a-z0-9]+([-_\.]?[a-z0-9])+\.[a-z]{2,4}", $email)) { 
    $errors[] = "this email address is not in a valid format."; 
    } 

    if(count($errors) == 0) 
    { 
    $message = "\n$name submitted the following message:\n\n$enquiry\n\nTheir contact details are as follows:\n\nName: $name\nEmail Address: $email\n\n"; 

    mail($mailto, "$sitename Referal from $name", $message, "From: $email"); 
    $returnurl = "http://".$_SERVER["SERVER_NAME"] 
       . ($_SERVER["SERVER_PORT"]!=80?":".$_SERVER["SERVER_PORT"]:"") 
       . dirname($_SERVER["PHP_SELF"]) . "/" 
       . $returnpage; 
    header("Location: " . $returnurl); 
    } 
    else 
    { 
    echo "<strong>Errors:</strong>"; 
    echo "<ul><li>".implode("</li>\n<li>",$errors)."</li></ul>"; 
    echo "<a href='javascript:history.go(-1)'>Back</a>"; 
    } 
?> 

如果这仍然不起作用，停止使用地点的待办事项：

readfile($returnpage); 

代替。

顺便说一下，你的代码示例不`吨看起来像全HTML网页，他们应该至少有

<html> 
    <body> 
    // Your content 
    </body> 
</html> 

Answer 2

如果您的网络服务器配置为显示警告（或者您可以启用它们进行开发），请提供它们。

看来您的header()调用不起作用。通常情况下，如果在此调用之前您有任何类型的输出。这可以是PHP脚本的开始<?标记之前的任何空格（空格，换行符等），或者它甚至可以是不可见的字符，如UTF-BOM。如果您使用Notepad ++之类的编辑器，则可以检查文件是否以UTF编码保存并确保其不含BOM。

Answer 3

短php（即<?,?>，<?= 'something' ?>）标签有时会产生问题。我总是把完整的PHP标签（<?php ?>，<?php echo 'something' ?>）

而且还最好是把ob_start();任何输出前，ob_end_clean();重定向之前。
