PHP 邮件功能发送重复邮件

Question

我构建了一个带有 reCaptcha 验证的表单，我的设置被重复发送电子邮件并从 Office 收到垃圾邮件。

我的错误是什么？

一切正常，除了填写表格时，我们当时收到了 2 封电子邮件。

<?php
if (isset($_POST["submit"])) {

    $url = 'https://www.google.com/recaptcha/api/siteverify';
    $privatekey = "******";

    $response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']);
    $data = json_decode($response);

    if(isset($data->success) AND $data->success==true){

        $to = "whois@sent.this";
        $emailfrom = $_POST['email'];
        $email = $_POST['email'];
        $nom = $_POST['nom'];
        $phone = $_POST['phone'];
        $subject = "Formulaire de Contact Web  ";
        $commentaire = $_POST['commentaire'];

        $headers  = 'MIME-Version: 1.0' . "\r\n";
        $headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";
        $headers .= "Reply-to: $emailfrom";

        $message = "

        }else{
            echo "mail could not be sent";
        }
    }else{
                header('Location: contactez-nous.php?CaptchaFail');
    }

}else{
    header('Location: contactez-nous.php?CaptchaError');

}

Answer 1

你有

// Always set content-type when sending HTML email
mail($to, $subject, $message, $headers); 
    // so on...all your mail parameters here


    if(mail($to, $subject, $message, $headers)){
                header('Location: contactez-nous.php?CaptchaPass');

    }else{
        echo "mail could not be sent";
    }

if语句里面的第二个mail(...)不仅判断邮件是否发送成功，还发送了邮件。所以删除第一个 mail(...) 并将其保留在 if 语句中。

Answer 2

双函数调用mail

// Always set content-type when sending HTML email
mail($to, $subject, $message, $headers); 

        // so on...all your mail parameters here
        if(mail($to, $subject, $message, $headers)){

试试这个：

// Always set content-type when sending HTML email
$mailOk = mail($to, $subject, $message, $headers); 

        // so on...all your mail parameters here
        if($mailOk){

或其他方式：

// Always set content-type when sending HTML email
// Remove this line --> mail($to, $subject, $message, $headers); 

        // so on...all your mail parameters here
        if(mail($to, $subject, $message, $headers))){

Answer 3

它到达时发送的第一封电子邮件

// Always set content-type when sending HTML email
mail($to, $subject, $message, $headers);

和第二封电子邮件在检查时到达

if(mail($to, $subject, $message, $headers)){

去掉第一个邮件功能就可以解决问题
