将 ajax 表单提交到 PHP 脚本时出现问题

Question

我正在使用 jquery 序列化发送表单数据，如下所示：

$.ajax({
            url: $form.attr('action'),
            type: 'POST',
            datatype : 'html',
            data: $('#form').serialize();,
            success: function(response) {
                if (response.status === "success") {
                    $('.result').text("Success!!");
                } else if (response.status === "error") {
                    $('.result').text("Error!!");
                }
            }
        });

这已成功传递到 PHP 脚本，但我的 PHP 中出现以下错误。

Parse error: syntax error, unexpected '$name' (T_VARIABLE) in C:\Users\Jberke\Documents\Projects\theRetros\src\process.php on line 10

我的PHP脚本如下：

<?php
$autoResponse = true; //if set to true auto response email will be sent, if you don't want autoresponse set it to false
$autoResponseSubject = "Demo Contact Form"; 
$autoResponseMessage = "Hi, thank you testing the JQuery Contact Form Demo.";
$autoResponseHeaders = "From: email_from@yourWebsite.com";  

//we need to get our variables first
$email_to =   'jamie_b25@hotmail.com';
$subject  =   'A enquiry for The Retros!'
$name     =   $_POST['name'];
$email    =   $_POST['email'];
$message  =   $_POST['message'];

$body = "From: $name \r\nMessage: \r\n$message";

/*the $header variable is for the additional headers in the mail function,
 we are asigning 2 values, first one is FROM and the second one is REPLY-TO.
 That way when we want to reply the email gmail(or yahoo or hotmail...) will know
 who are we replying to. */
$headers  = "From: $email\r\n";
$headers .= "CC: test@test.com\r\n";
$headers .= "Reply-To: $email\r\n";


if(mail($email_to, $subject, $body, $headers)){
    if($autoResponse === true){
        mail($email, $autoResponseSubject, $autoResponseMessage, $autoResponseHeaders);
    }
    echo 'success'; // we are sending this text to the ajax request telling it that the mail is sent..
}else{
    echo 'error';// ... or this one to tell it that it wasn't sent
}

?>

我不确定这里发生了什么，但似乎没有正确访问序列化数据。这是我序列化数据的控制台日志的 sn-p。

Answer 1

您在给出错误的那一行的 PHP 脚本中缺少一个分号。

$subject  =   'A enquiry for The Retros!'  // <--- Here a ; should be added.
$name     =   $_POST['name'];
$email    =   $_POST['email'];

通常，当您遇到这样的语法错误时，它实际上是在上面的行中（有时甚至更高）。 PHP 解析器认为前面的语句没有完成（因为缺少分号），并继续解析相同的语句。那时它会被下一个语句的意外开始弄糊涂。因此，当您在第 10 行收到这样的消息时，请务必查看第 9 行或第 8 行。

Answer 2

很简单，你在这里忘记了分号：

$subject  =   'A enquiry for The Retros!'

应该是：

$subject  =   'A enquiry for The Retros!';
