Question

我对编码非常陌生，所以请随意像对待白痴一样对待我。我已经设法创建了一个带有bootstrap 3的模态联系表单。第一次运行时它很漂亮，弹出然后将信息发送到我的电子邮件。然后我有一个刷新功能，所以在提交后它返回到同一页面，当再次按下链接时，模态会弹回以清除任何先前输入的信息。这是有效的。但是，当你提交这段时间时，我的电子邮件中没有任何内容。

现在我有一个理论认为正在发生的事情是变量在第一次提交后清除，所以php代码第二次不能工作。但这只是一个我根本不擅长php的理论。

以下是模态联系表格脚本和我使用的PHP。

<?php
    if (isset($_POST["submit"])) {
        $name = $_POST['name'];
        $email = $_POST['email'];
        $message = $_POST['message'];
        $human = intval($_POST['human']);
        $from = 'Ambedo'; 
        $to = 'charlieboman@live.com.au'; 
        $subject = 'Message from Ambedo ';

        $body ="From: $name\n E-Mail: $email\n Message:\n $message";

        if (!$errName && !$errEmail && !$errMessage) {
            (mail ($to, $subject, $body, $from));
        }
    }
?>

Answer 1

如果您将表单提交到同一页面，并且如果要在提交表单后清除表单，请从表单中删除以下行并将数据提交到同一页面。

onsubmit="setTimeout(function () { window.location.reload(); }, 10)"

如果您将表单提交到任何其他php页面，并且如果您想在提交表单后清除表单，请在“mail（）”函数之后添加以下行

header('Location: <http://www.yoursite.com>');

如果您将表单提交到任何php页面，并且在提交表单后不想清除表单，请使用ajax。

$(document).rady(function(){
$("form").submit(function(){
    $.ajax({
        url: "your_php_file.php",
        data:$('form').serialize(),
        dataType:'html',
        success: function(result){
             alert(result);
        }
    });
});});

您可以在php文件中获取表单数据，然后进行处理。您在php文件中“回显”的内容将显示在屏幕上的警告框中。

Answer 2

如果不了解更多细节，很难确切知道发生了什么。

但是，您应该在PHP代码中执行一些基本的错误检查，例如检查变量是否实际设置以及mail()函数实际返回true（如果您阅读PHP mail() docs ，它会告诉您mail()将返回一个布尔值（true / false）。您还会注意到第四个参数是标题）。

我将向您展示可以做什么的示例（有很多方法），主要关注您应该检查错误。

<?php
if (isset($_POST["submit"])) {
    if (isset($_POST['name'], $_POST['email'], $_POST['message'], $_POST['human'])) {
        // Checks if the variables can be set, so that we don't get undefined index errors
        // You could also do other forms of error-checking here
        // Such as validating the email-address, names and such
        $name = $_POST['name'];
        $email = $_POST['email'];
        $message = $_POST['message'];
        $human = intval($_POST['human']);

        $errorOccured = false; // No errors
    } else {
        $errorOccured = true; // Some of the variables can't be set - this is an error
    }

    $to = 'charlieboman@live.com.au'; // The address we're sending the form to
    $subject = 'Message from Ambedo '; // Subject of the message

    // Headers in the email goes here...
    $headers  = "Content-type: text/html; charset=UTF-8<br />";
    $headers .= "From: Ambedo <contactform@yourwebsite.com> <br />";
    $headers .= "To: Ambedo <$to> \r\n";
    $headers .= "Reply-To: ".$name."  <".$email.">" . "\r\n";

    // Body of the email: the contents that will be shown
    $body = "From: $name\n";
    $body .= "E-Mail: $email\n";
    $body .= "Message:\n $message";

    if (!$errorOccured) { // If we had no error, we can proceed
        if (mail ($to, $subject, $body, $from)) { // If mail is sent, all is good!
            // Message was sent (mail returned true)!
        } else {
            // An error occurred sending the email, could be for various reasons...
            // Display error message here
        }
    } else { // $errorOccured == true, so something bad happened...
        // Not all variables were set, so email couldn't be sent
        // Deal with it here, display error message and show the form again
    }
}
?>

Answer 3

您的完整代码如下：

        $body ="From: $name\n E-Mail: $email\n Message:\n $message";

        if ($name!='' && $email!='' && $message!='' ) {
            if(mail ($to, $subject, $body, $from)){
               header('Location:Ambedo_Contact.php');
            }
         }
    } 
?>

请注意，我在发送详细信息后删除了onsubmit事件并将当前页面重定向到同一页面。

联系表单发送，刷新页面和表单，但在提交后不发送任何内容
