PHP发送两封电子邮件

时间：2014-10-17 03:17:15

标签： php email

我有这个代码，我从其他脚本和我在互联网上找到的东西放在一起，

不知何故，当我刚刚加载页面时，它发送了两封电子邮件，一封电子邮件，当我提交时，它就是第二封电子邮件。

此外，header()并未将我发送到我想要的页面...它只是停留在同一个表单页面上，如果有人可以帮我查明发生了什么，那就太多了赞赏，我认为它确实与帖子有关，但我不能因为我的爱而弄明白！

谢谢

它向您发送了两封电子邮件，因为您需要在条件语句中设置整个代码。

将isset()与已命名的提交按钮结合使用，该按钮仅在单击提交按钮后发送邮件，而不是在页面加载时发送。

<input type="submit" name="submit" value="Submit">

修改为：

<?php

if(isset($_POST['submit'])){

$myemail = "links@loadsofads.com";
$subject = "Link Submission";
$message = "Your Link Submission form has been submitted by:
Website Name: $name
E-mail: $email
URL: $website
Category: $category
Description:
$comment";
mail($myemail, $subject, $message);

header('Location: submitthanks.php');
exit;
}

关于标题不重定向是因为您在标题之前输出，如果已设置/ error reporting，则会发出Headers already sent...警告。

在页面顶部添加ob_start();并在<?php ?>标记内设置有时会有所帮助，并置于<!DOCTYPE html...

之上

即：

<?php ob_start(); ?>
<!DOCTYPE html ...

最好将表单操作用于其他页面，而不是放在同一页面上，并将邮件代码放在该文件中。

如果您希望使用现有代码而不使用第二页作为邮件处理程序，则另一种选择是使用元刷新方法。

例如，代替header()：

$url = "submitthanks.php";

print "<meta HTTP-EQUIV=Refresh CONTENT=\"0; URL=$url\">";

编辑： - 重写＃2

请务必将此行$myemail = "email@example.com";更改为您的电子邮件地址。

另外，还有一个mail() header丢失，很可能会向垃圾邮件发送邮件，
并添加了from Name，以便更加个性化。

<?php

ob_start(); // prevents headers already sent warning

?>

您需要将这部分代码放在帖子部分

中 
if ($_SERVER["REQUEST_METHOD"] == "POST"){
    $myemail = "links@loadsofads.com";
    $subject = "Link Submission";
    $message = "Your Link Submission form has been submitted by:
    Website Name: $name
    E-mail: $email
    URL: $website
    Category: $category
    Description:
    $comment";
    mail($myemail, $subject, $message);
    header('Location: submitthanks.php');
