PHP 联系表单重定向

Question

所以我有一个基本上当它提交时它会运行我在 "contact-process.php" 上的内容并且当点击提交时它会转到该页面然后显示成功或错误，我该如何制作提交在同一页面上显示成功或错误消息，并清除表单以显示已发送。这是我网页上的代码。

<form class="form-horizontal" method="post" action="contact-process.php">
                    <div class="form-group">
                        <label for="name" class="col-sm-2 control-label">Name</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" id="name" name="name" placeholder="First & Last Name">
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="email" class="col-sm-2 control-label">Email</label>
                        <div class="col-sm-10">
                            <input type="email" class="form-control" id="email" name="email" placeholder="example@gmail.com">
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="email" class="col-sm-2 control-label">Subject</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" id="subject2" name="subject2" placeholder="Logo Design - Request">
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="message" class="col-sm-2 control-label">Message</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" rows="4" name="message" placeholder="Please explain your request in detail. Provide screenshots & links."></textarea>
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="human" class="col-sm-2 control-label">5 x 2 = ?</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" id="human" name="human" placeholder="Your Answer">
                        </div>
                    </div>


                    <div class="form-group">
                        <div class="col-sm-10  col-sm-offset-2">
                            <input type="submit"  class="btn-primary btn" id="submit" name="submit" value="Send">
                        </div>
                    </div>
                </form>

然后这是我在 "contact-process.php"

上的代码

<?php
if(isset($_POST['submit'])){
$name = $_POST["name"];
$email = $_POST["email"];
$subject2 = $_POST["subject2"];
$message = $_POST["message"];
$human = intval($_POST['human']);

$EmailTo = "example@outlook.com";
$Subject = "Message Received";

if ($human !== 10) {
    $errHuman = 'Your anti-spam is incorrect';
}

// prepare email body text
 $Body = "Name: ";
$Body .= $name;
$Body .= "\n";

$Body .= "Email: ";
$Body .= $email;
$Body .= "\n\n\n";

$Body .= "Subject: ";
$Body .= $subject2;
$Body .= "\n";

$Body .= "Message: ";
$Body .= $message;
$Body .= "\n";

// send email
$success = mail($EmailTo, $Subject, $Body, "From:".$email);

// redirect to success page
if ($success){
   echo "<div class='alert alert-success'>Thank You! I will be in touch</div>";
}else{
    echo "<div class='alert alert-danger'>Sorry there was an error sending your message. Please try again later.</div>";
}
}
?>

将 html 放入您的 PHP 脚本中，如下所示：

<form class="form-horizontal" method="post" action="#">
                    <div class="form-group">
                        <label for="name" class="col-sm-2 control-label">Name</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" id="name" name="name" placeholder="First & Last Name">
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="email" class="col-sm-2 control-label">Email</label>
                        <div class="col-sm-10">
                            <input type="email" class="form-control" id="email" name="email" placeholder="example@gmail.com">
                        </div>
                    </div>
                    <div class="form-group">
                        <label for="email" class="col-sm-2 control-label">Subject</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" id="subject2" name="subject2" placeholder="Logo Design - Request">

                    </div>
                </form> 

<?php

    if($_POST["name"] != "" AND $_POST["email"] != "" AND $_POST["subject2"] != "" AND $_POST["message"] != "") {

            }
        }


    }else{

        echo "<div class='alert alert-success'>Data incomplate</div>";
    }

}else{
    // do nothing
    }
?>

编辑

行动将是：

action="<?php echo $_SERVER['PHP_SELF']; ?>"

或

action="#"

或

action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>"

先求你...再问

你需要知道一点Ajax是一种可以让你与phpjavascript/JSON

交流的技术

制作一个带有警报功能的脚本，然后在脚本中将 location.reload 放在成功部分。
