PHP發送兩封電子郵件

[英]PHP sending two emails

 原文  2014-10-17 03:17:14  8   2    php/ email

問題描述

我將這段代碼與其他腳本和在網上找到的東西放在一起，

它以某種方式向我發送了兩封電子郵件，當我剛剛加載頁面時一封電子郵件，而當我提交頁面時第二封電子郵件。

另外， header()並沒有將我發送到我想要的頁面...它只是停留在同一表單頁面上，如果有人可以幫助我了解發生了什么，我將不勝感激確實與自我相關，但我無法為我的愛弄清楚！

謝謝

2 個解決方案

它向您發送兩封電子郵件，因為您需要在條件語句中設置整個代碼。

將isset()與您已經命名的“提交”按鈕結合使用，該按鈕僅在單擊“提交”按鈕后才會發送郵件，而不會加載頁面。 

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

修改為： 

<?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;
}

關於標頭不重定向是因為您在標頭之前輸出，如果已設置/打開錯誤報告 ，則將在標頭之前輸出Headers already sent...警告。

添加ob_start(); 在頁面頂部並在<?php ?>標記內設置有時會有所幫助，並置於<!DOCTYPE html...上方<!DOCTYPE html...

即： 

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

您最好在另一個頁面上而不是在同一頁面上使用表單操作，並將郵件代碼放入該文件中。

如果您希望使用當前代碼而不使用第二頁作為郵件處理程序，則另一種選擇是使用元刷新方法。

例如，代替header() ： 

$url = "submitthanks.php";

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

編輯： -重寫＃2

確保更改此行$myemail = "email@example.com"; 作為您的電子郵件地址。

另外，缺少mail()標頭 ，很可能會將郵件發送到垃圾郵件，
並添加了一個from Name因此更具個性化。 

<?php

ob_start(); // prevents headers already sent warning

?>

您需要將代碼的這一部分放在發布部分 

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');
