PHP 表单、MailFonction 和 Google reCaptcha 验证问题

Question

我对使用邮件功能编写验证码验证程序的方式有疑问。

Captcha Success 运行良好。当验证码失败时，我在表单页面中收到了正确的消息，但是 PHP 程序仍然让电子邮件发送。我只需要知道如何只在成功部分设置邮件功能。

谁能帮我解决 reCaptcha 验证问题？

谢谢。

这里是 PHP 源代码：

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

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

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

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

        header('Location: appel_de_service.php?CaptchaPass=True');

    }else{

        header('Location: appel_de_service.php?CaptchaFail=True');

    }

 $to = "MASKED";
 $from = $_POST['courriel'];
 $from_name = $_POST['nom_responsable'];
 $subject = "Reception d'un appel de service ";
 $nom_compagnie = $_POST['nom_compagnie']; // required
 $adresse = $_POST['adresse']; // required
 $ville = $_POST['ville'];
 $province = $_POST['province'];
 $code_postale = $_POST['code_postale'];
 $nom_responsable = $_POST['nom_responsable'];
 $courriel = $_POST['courriel'];
 $telephone = $_POST['telephone'];
 $marque = $_POST['marque'];
 $numero_modele = $_POST['numero_modele'];
 $garantie = $_POST['garantie'];
 $description = $_POST['description'];              
 $disponibilite = $_POST['disponibilite']; // required
 $coordonnees = $_POST['coordonnees']; // required

 $headers  = 'MIME-Version: 1.0' . "\r\n";
 $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
 $headers .= "Reply-to: $courriel";

出现此问题的原因可能有很多。 reCpatcha Google 插件失败的最常见原因是用户通过 ajax 和 jquery 或 javascript 和 php 进行验证的方式是错误的。我将向您展示的下一个代码（假设您已经在 Goolge Recaptcha 中验证了一个帐户），将教您如何在单击带有 php、ajax 的按钮后验证 reCaptcha 答案和 jquery。您好！

从这里下载 recpatcha 库 https://mega.nz/#!qw4Snb6Z!3Mgq2UvD3PmQJ9ts9sQdHcV86Le8-wtz05IEr2b-3mw

$(function() {
    //First we have to listen on a event click (button) and extract the values of the inputs
    $('body').on('click','.myButtonClass', function() {
        $email    = $('#emailID').val();
        $password = $('#passwordID').val();
        $recaptcha = $('textarea').val();
        //We save in a object our values
        $x = {
            action:'validate',
            email:$email,
            password:$password
            captcha:$recaptcha
        };

        //We execute ajax calling a php file for POST method
        $.post('file.php',$x,function(callback) {
            $('.answer').html(callback);

已解决。问题是 PHP if() 和 else() 的构造需要在数据收集填写到表单之后。

正确的代码如下：

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

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

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

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

        $to = "who@domain.com";
        $from = $_POST['courriel'];
        $from_name = $_POST['nom_responsable'];
        $subject = "Reception d'un appel de service ";
        $nom_compagnie = $_POST['nom_compagnie'];
        $adresse = $_POST['adresse'];
        $ville = $_POST['ville'];
        $province = $_POST['province'];
        $code_postale = $_POST['code_postale'];
        $nom_responsable = $_POST['nom_responsable'];
        $courriel = $_POST['courriel'];
        $telephone = $_POST['telephone'];
        $marque = $_POST['marque'];
        $numero_modele = $_POST['numero_modele'];
        $garantie = $_POST['garantie'];
        $description = $_POST['description'];              
        $disponibilite = $_POST['disponibilite'];
        $coordonnees = $_POST['coordonnees'];

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

        $message = "
        ";

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

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

}else{
    header('Location: appel_de_service.php?CaptchaError');

}
