Php联系表问题

Question

我在使用此代码时遇到问题。提交填写的表单后，提交按钮旁边没有显示显示消息（已发送电子邮件！）。我需要在联系表单上的提交按钮旁边显示已发送的电子邮件消息。提交表单后，即使在刷新或返回操作后，我也需要清除表单字段。请帮我解决此代码

Answer 1

您可以在发送电子邮件后重定向页面，也可以设置$msg='email sent'; 之类的变量并在提交按钮之前调用此变量。

    $action=$_REQUEST['action'];

    if ($action!="")    /* display the contact form */
        {
$your_name = $_REQUEST['your_name'];

    $email = $_REQUEST['email'];

    $mobile_number = $_REQUEST['mobile_number'];

    $message = $_REQUEST['message'];

    $formcontent="From: $your_name \n Email: $email \n Phone Number: $mobile_number \n Message: $message";

    $recipient = "name@email.com";

    $subject = "Contact Form";

    $mailheader = "From: $email \r\n";

        if (($your_name=="")||($email=="")||($message==""))
            {
            header('location: yoururl?msg=error');
            //$msg   =  "All fields are required, please fill <a href=\"\">the form</a> again.";
            }
        else{       
            @mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

            header('location: yoururl?msg=succss');
            //$msg   =  'Email Sent!';
            }
        }
        ?>

        <form name="contactform" method="post" enctype="multipart/form-data">

            <input type="hidden" name="action" value="submit">

          <label for="your_name">Your Name <font color="red">*</font></label>
          <input  type="text" id="reset" name="your_name"  placeholder="Enter Your Name" maxlength="20" size="40" >

          <label for="email">Email Address <font color="red">*</font></label>
          <input  type="email" id="reset" name="email" placeholder=" Enter Your E-mail Address" maxlength="20" size="40" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}$" required>

          <label for="mobile_number">Mobile Number</label>
          <input  type="tel" id="reset" name="mobile_number" pattern="[0-9]{1}[0-9]{9}" placeholder="Enter Your Phone Number by Adding Country Code (eg: +91.,)" maxlength="30" size="40" >

          <label for="message">Message <font color="red">*</font></label>
          <textarea  name="message" id="reset" placeholder="Your Message Goes Here" maxlength="1000" cols="62" rows="10" required></textarea>
    <?php if(isset($_REQUEST['msg']) and $_REQUEST['msg']=='success'){echo "Email sent!";}if(isset($_REQUEST['msg']) and $_REQUEST['msg']=='error'){echo "All fields are required, please fill <a href=\"\">the form</a> again.";} ?>
            <?php echo $msg; ?>
            <input type="submit" value="Submit">
            </form>

您的代码应该是这样的。注意isset($_POST['submit']、$msg、value=""。

<?php

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

    $your_name = $_REQUEST['your_name'];

    $email = $_REQUEST['email'];

    $mobile_number = $_REQUEST['mobile_number'];

    $message = $_REQUEST['message'];

    $formcontent="From: $your_name \n Email: $email \n Phone Number: $mobile_number \n Message: $message";

    $recipient = "name@email.com";

    $subject = "Contact Form";

    $mailheader = "From: $email \r\n";

        if (($your_name=="")||($email=="")||($message==""))
            {
            $msg = "All fields are required";
            }
        else{       
            @mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

            $msg = "Email Sent";
            }
        }  
    ?>

        <form name="contactform" method="post" enctype="multipart/form-data">

            <input type="hidden" name="action" value="submit">

          <label for="your_name">Your Name <font color="red">*</font></label>
          <input  type="text" id="reset" name="your_name"  placeholder="Enter Your Name" maxlength="20" size="40" value="">

          <label for="email">Email Address <font color="red">*</font></label>
          <input  type="email" id="reset" name="email" placeholder=" Enter Your E-mail Address" maxlength="20" size="40" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}$" required value="">

          <label for="mobile_number">Mobile Number</label>
          <input  type="tel" id="reset" name="mobile_number" pattern="[0-9]{1}[0-9]{9}" placeholder="Enter Your Phone Number by Adding Country Code (eg: +91.,)" maxlength="30" size="40" value="">

          <label for="message">Message <font color="red">*</font></label>
          <textarea  name="message" id="reset" placeholder="Your Message Goes Here" maxlength="1000" cols="62" rows="10" required></textarea>

            <input type="submit" name="submit" value="Submit">

          <?php echo $msg; ?>
            </form>
