PHP 表单正在发送空白电子邮件

Question

我查看了其他 SO 答案，但没有得到答案。我正在制作一个简单的 HTML 表单，其中包含一个用于发送电子邮件的 PHP 脚本。简单的。除了它不工作。这是 HTML:

<form action="" method="post" id="contactform">
    <fieldset>
        <legend>Contact Form</legend>
        <p><label>First Name: </label><input type="text" name="first_name" class="text" required></p>
        <p><label>Last Name: </label><input type="text" name="last_name" class="text" required></p>
        <p><label>Email: </label><input type="text" name="email" class="text" required></p>
        <p><label>Message:</label><textarea rows="5" name="message" cols="30" class="message" required></textarea></p>
        <input type="submit" name="submit" value="Submit" class="submit">
    </fieldset>
</form>

这是 AJAX:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
    $("#contactform").submit(function(){
      $.get("contactsend.php", function(data){
        alert(data);
      })
      return false;
    })
</script>

这里是 contactsend.php：

<?php 
$to = "shubhang.desai@gmail.com"; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$subject = "Form submission";
$message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];

$headers = "From: " . $from;
if (mail($to,$subject,$message,$headers)) {
    echo "Mail sent.";
} else {
    echo "An error occured. Try again later.";
}

?>

当点击提交时，页面显示 "Mail sent."，但电子邮件通过空白。我不确定为什么数组 _POST 会是空的。有人可以帮我吗？

提前致谢:)

Answer 1

尝试：

$date = date( 'r' );

$phpversion = phpversion();

$headers = "From: ".$from."\nDate: ".$date."\nX-Mailer: PHP v".$phpversion."\nMIME-Version: 1.0\nContent-Type: text/html; charset=iso-8859-1\nContent-Transfer-Encoding: 8bit";

你的问题是你还没有通过 ajax 向服务器发送任何数据。

试试这个：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$("#contactform").submit(function(){
  jQuery.ajax({
        type: "POST",
        url: "contactsend.php",
        data: jQuery(this).serialize(),
        success: function(data){
            alert(data);
        }
    });
    return false;
})
</script>

Php:

<?php 
$to         = "shubhang.desai@gmail.com"; // this is your Email address
$from       = $_POST['email']; // this is the sender's Email address
$first_name = $_POST['first_name'];
$last_name  = $_POST['last_name'];
$subject    = "Form submission";
$message    = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];

$headers    = 'MIME-Version: 1.0' . "\r\n";
$headers   .= 'Content-type: text/html; charset=utf-8' . "\r\n";
$headers   .= 'From: ' .$from. "\r\n";

if (mail($to,$subject,$message,$headers)) {
    echo "Mail sent.";
} else {
    echo "An error occured. Try again later.";
}

Answer 3

您未能将表单中的值发送到您的服务器。
您可以使用 .serialize() 来获取值。它会将它们转换为具有正确编码值的字符串。

$("#contactform").submit(function () {
    $.get("contactsend.php", $(this).serialize(), function(data) {
        alert(data);
    });
    return false;
});

Answer 4

你没有发送任何数据，试试这个

<script      src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$("#contactform").submit(function(){
var details = $(this).serialize();
  $.get("contactsend.php",details, function(data){
    alert(data);
  })
  return false;
})
</script>

"serialize"函数自动为表单创建查询字符串，您还可以序列化单个输入字段。
