我想在提交表单时回显消息

Question

我不太擅长 PHP（更多的是前端开发人员），我正在为客户做网站。到目前为止，除了一件事，我一切正常。当用户填写联系表格并成功提交时，我想显示一条消息，告诉他们电子邮件已发送。我已经设置了 div 我只是不知道谁用 PHP 来执行它。

<div class="sent">Email has been sent.</div>
    <form action="" method="POST" class="contact-form"> 
    <img class="close" src="images/close-icon.png">     
        <div class="top-title">Contact Us</div>
        <input type="hidden" name="action" value="submit"> 
        <div class="input-title">Name*</div> 
        <input class="input" name="name" type="text" value="" size="30" required><br>
        <div class="input-title">Phone Number*</div> 
        <input class="input" name="phone" type="text" value="" size="30" required><br>
        <div class="input-title">Email Address*</div>
        <input class="input" name="email" type="text" value="" size="30" required><br> 
        <div class="input-title">How did you hear about us?</div>  
        <input class="input" name="company" type="text" value="" size="30"/><br> 
        <div class="input-title">Let us know how we can help you</div>
        <textarea class="textarea" name="message" rows="7" cols="30"></textarea><br> 
        <div class="required">*Fill is required</div>
        <input class="submit-button" type="submit" value="Send Email"/> 
    </form> 
    <?php              
        { 
        $name=$_POST['name']; 
        $email=$_POST['email']; 
        $phone=$_POST['phone']; 
        $company=$_POST['company']; 
        $message= "\r\nName: " . $_POST['name'] ."\r\nPhone Number: ". $_POST['phone']."\r\nEmail: ". $_POST['email'] ."\r\nHow you know the company: ".$_POST['company'] ."\r\nReason for message: ".$_POST['message'];

            $from="From: $name<$email>\r\nReturn-path: $email"; 
            $subject="GS Website Message"; 
            mail("name@email.com", $subject, $message, $from); 
        }
    ?>

Answer 1

更改：（并使用条件语句）

mail("name@email.com", $subject, $message, $from);

至：

if(mail("name@email.com", $subject, $message, $from)){
   $sent = "Message sent";
}

然后修改：

<div class="sent">Email has been sent.</div>

读作：

<div class="sent"><?php if(!empty($sent)) { echo $sent; } ?></div>

鉴于您是 PHP/forms 的新手，最好也检查一下您的输入是否为空，否则您将面临收不到邮件或收到空数据的风险。

http://php.net/manual/en/function.empty.php

也在条件语句中设置。

即：使用 NOT 空：! 是 PHP 中的 NOT 运算符。

if(!empty($_POST['var'])){...}

编辑：

逻辑需要倒过来

首先，将 PHP 放在 HTML 表格上方。

我还在您的提交按钮中添加了一个 submit 名称属性，在 div.

中有一个条件语句和一个 ternary operator

<?php

 if(isset($_POST['submit'])){

        $name=$_POST['name']; 
        $email=$_POST['email']; 
        $phone=$_POST['phone']; 
        $company=$_POST['company']; 
        $message= "\r\nName: " . $_POST['name'] ."\r\nPhone Number: ". $_POST['phone']."\r\nEmail: ". $_POST['email'] ."\r\nHow you know the company: ".$_POST['company'] ."\r\nReason for message: ".$_POST['message'];

            $from="From: $name<$email>\r\nReturn-path: $email"; 
            $subject="GS Website Message"; 


if(mail("email@example.com", $subject, $message, $from)){

$sent = "Message sent";

    }
}
    ?> 

<div class="sent"><?php echo isset($sent) ? $sent : ''; ?></div>


    <form action="" method="POST" class="contact-form"> 

    <img class="close" src="images/close-icon.png">     


        <div class="top-title">Contact Us</div>
        <input type="hidden" name="action" value="submit"> 
        <div class="input-title">Name*</div> 
        <input class="input" name="name" type="text" value="" size="30" required><br>
        <div class="input-title">Phone Number*</div> 
        <input class="input" name="phone" type="text" value="" size="30" required><br>
        <div class="input-title">Email Address*</div>
        <input class="input" name="email" type="text" value="" size="30" required><br> 
        <div class="input-title">How did you hear about us?</div>  
        <input class="input" name="company" type="text" value="" size="30"/><br> 
        <div class="input-title">Let us know how we can help you</div>
        <textarea class="textarea" name="message" rows="7" cols="30"></textarea><br> 
        <div class="required">*Fill is required</div>
        <input class="submit-button" type="submit" value="Send Email" name="submit"/> 
    </form>

Answer 2

$password=md5($_POST ['password']);

$password3 =md5($_POST ['password2']);
if($password != $password3)
{
   $message = "Passwords do not match";

}

etc.

you need add 

<form>
<div class="form-group">
                                            <input type="password" name="password"  id="password" class="form-control" placeholder="Password *" value="" required/>
                                        </div>
                                        <div class="form-group">
                                            <div class="message"><?php if(!empty($message)) { echo $message; } ?></div>
                                            <input type="password" name="password2" class="form-control" id="password2" placeholder="Confirm Password *" value="" required/>
                                        </div>
</form>

我想在提交表单时回显消息
