Question

我正在尝试将php邮件表单设置到我的网站中。首先，我希望在提交后保留表单值。如果用户留下空字段并按下提交按钮，该用户将不得不再次编写相同的内容。我设法用结构<?php if (isset($_POST['Fields'])){echo htmlentities($_POST['Fields']); }?>来做这件事但是，在提交表单值后，我将表单和php邮件代码相互链接。我还没设法做到这一点。我不了解php。有代码：

我的表格（在contact.php内）：

＆＃13;

<form method="post" action="mail.php">
                <label for="Name">Name:</label>
                <input type="text" name="Name" id="Name" value="<?php if (isset($_POST['Name'])){echo htmlentities($_POST['Name']); }?>" />
                
                <label for="Subject">Subject:</label>
                <input type="text" name="Subject" id="Subject" value="<?php if (isset($_POST['Subject'])){echo htmlentities($_POST['Subject']); }?>"/>

                <label for="Phone">Phone:</label>
                <input type="text" name="Phone" id="Phone" value="<?php if (isset($_POST['Phone'])){echo htmlentities($_POST['Phone']); }?>"/>
    
                <label for="Email">Email:</label>
                <input type="text" name="Email" id="Email" value="<?php if (isset($_POST['Email'])){echo htmlentities($_POST['Email']); }?>"/>
                
                <label for="Message">Message:</label><br />
                <textarea name="Message" rows="20" cols="20" id="Message">
                    <?php if (isset($_POST['Message'])){echo htmlentities($_POST['Message']); }?>
                </textarea>

                <input type="submit" name="submit" value="Send" class="submit-button" />
 </form>

＆＃13;

我的php文件（mail.php）：

＆＃13;

<?php
if(!isset($_POST['submit']))
{
	//This page should not be accessed directly. Need to submit the form.
	echo "error; you need to submit the form!";
}
$name = $_POST['Name'];
$subject = $_POST['Subject'];
$phone = $_POST['Phone'];
$visitor_email = $_POST['Email'];
$message = $_POST['Message'];

//Validate first
if(empty($name)||empty($visitor_email)||empty($message)) 
{
    header('Location: contact.php#jump'); // I'm gonna writing new stuff here
    exit;
}

if(IsInjected($visitor_email))
{
    header('Location: contact.php#jump'); // I'm gonna writing new stuff here
    exit;
}

$email_from = 'updatedmail@mail.com';//<== update the email address
$email_subject = "Email from your web site";
$email_body = "You have received a new message via the web mail form \n".
    "Name: $name \n". 
    "E-Mail: $visitor_email \n".
    "Subject: $subject \n".
    "Message: $message \n".
    "Phone Number: $phone \n".

    
$to = "mymail@mymail.mail";//<== update the email address
$headers = "From: $email_from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: contact.php#jump'); // I'm gonna writing new stuff here


// Function to validate against any email injection attempts
function IsInjected($str)
{
  $injections = array('(\n+)',
              '(\r+)',
              '(\t+)',
              '(%0A+)',
              '(%0D+)',
              '(%08+)',
              '(%09+)'
              );
  $inject = join('|', $injections);
  $inject = "/$inject/i";
  if(preg_match($inject,$str))
    {
    return true;
  }
  else
    {
    return false;
  }
}
   
?>

Answer 1

你必须在contact.php中包含mail.php。所以在contact.php中，在顶部写

<?php include("mail.php");?>

如果某个文件夹中的mail.php包含该文件夹名称，则如下所示：

<?php include("foldername/mail.php");?>

从 action =＆＃34; mail.php＆＃34;

中删除mail.php

如果它不起作用，请告诉我。：）
