Question

我正在尝试通过简单的PHP邮件脚本发送邮件。我已多次检查代码，页面将转到“Thankyou_page”，好像邮件应该已发送，但我还没有收到电子邮件。任何想法为什么这不起作用？

<?php
/*
This first bit sets the email address that you want the form to be submitted to.
You will need to change this value to a valid email address that you can access.
*/
$webmaster_email = "email@mail.com";
$subject = "Contact Us";

/*
This bit sets the URLs of the supporting pages.
If you change the names of any of the pages, you will need to change the values here.
*/
$feedback_page = "feedback_form.html";
$error_page = "error_message.html";
$thankyou_page = "thank_you.html";

/*
This next bit loads the form field data into variables.
If you add a form field, you will need to add it here.
*/
$email_address = $_REQUEST['email_address'] ;
$comments = $_REQUEST['comments'] ;

/*
The following function checks for email injection.
Specifically, it checks for carriage returns - typically used by spammers to inject a CC list.
*/
function isInjected($str) {
    $injections = array('(\n+)',
    '(\r+)',
    '(\t+)',
    '(%0A+)',
    '(%0D+)',
    '(%08+)',
    '(%09+)'
    );
    $inject = join('|', $injections);
    $inject = "/$inject/i";
    if(preg_match($inject,$str)) {
        return true;
    }
    else {
        return false;
    }
}

// If the user tries to access this script directly, redirect them to the feedback form,
if (!isset($_REQUEST['email_address'])) {
header( "Location: $feedback_page" );
}

// If the form fields are empty, redirect to the error page.
elseif (empty($email_address) || empty($comments)){
header( "Location: $error_page" );
}

// If email injection is detected, redirect to the error page.
elseif ( isInjected($email_address) ) {
header( "Location: $error_page" );
}

// If we passed all previous tests, send the email then redirect to the thank you page.
else {
mail( $webmaster_email, $subject,
  $comments, "From: " . $email_address);
header( "Location: $thankyou_page" );
}
?>

Answer 1

使用编写良好的库，如SwiftMailer或PHPMailer。使用mail函数发送电子邮件而没有很好的PHP命令是一个杀手。

PhpMailer vs. SwiftMailer?

Answer 2

您是否在php.ini文件中指定了smtp主机？如果是这样是正确的吗？

此外，禁用标题并打印邮件功能的输出以查看它是否超过。在php.ini文件中启用错误报告也是一个好主意。

Answer 3

email@mail.com是有效的电子邮件吗？

PHP邮件脚本，未发送电子邮件
