所以，我想到了 php，但不断出现内部服务器错误。我做错了什么？我已经设置好 sendmail.php 文件、Thankyou.html 文件和应用程序文件。为什么当我点击提交进行测试运行时，它会转到 HTTP 500 内部服务器错误页面？

Answer 1

我同意其他人的观点，您真的应该阅读 cmets 中链接的邮件功能。函数的结构是mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

您需要将邮件正文中所需的所有内容放入一个字符串中，然后将该字符串传递给邮件函数。最后，它看起来像

mail( "cuinfo@creativeurethanes.com", "Application", $body, "From: $emailaddress" );

确保您正确格式化 $body，使其不是一大堆文本（在每一行之后放置 \r\n）

代码示例如下：

<?php
$body = "First Name: ".$_REQUEST['first_name'] ."\r\n";
$body .= "Last Name: ".$_REQUEST['last_name'] ."\r\n";
$body .= "SSN Name: ".$_REQUEST['ssn'] ."\r\n";

// Keep adding the information here

mail( "cuinfo@creativeurethanes.com", "Application",$body, "From: $emailaddress\r\n" );
header( "Location: http://www.creativeurethanes.com/Thankyou.html" );

?>

确保您还在发件人地址后添加 \r\n

1: php 中有一些命名变量的约定。看看http://de3.php.net/manual/en/language.variables.basics.php -> 他们不能以数字开头。
2：$_REQUEST 是超全局的，但您不能假设所有值都已设置。您必须使用 isset()-funcion (http://de3.php.net/manual/en/function.isset.php) 检查每个。
3：如您所见，您不能指望邮件功能始终有效。如果您未使用 (if(mail(...))) 进行检查，请勿将用户重定向到成功站点。
4：要找出它抛出 500 错误的原因，您必须检查您的服务器日志。如果您的服务器配置为不显示它们，则由于 php 错误可能会出现此错误。您可能必须在脚本中首先重新配置和/或设置这些行：

ini_set('display_errors', 1);
error_reporting(E_ALL);
