Question

我有一个位于contact.php上的html表单，这是代码

<?php  

header('Content-Type: text/html; Charset=utf-8');

mb_internal_encoding('UTF-8');

date_default_timezone_set('Europe/Warsaw');

?>

<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

  <title>Prove</title>

</head>
<body>

  <form  action="test.php" method="post" name="post">

        <label for="email">E-Mail</label>

                 <input type="email" id="email" name="email" />

                  <label for="name">Name</label>

                  <input id="name" name="name" />

      <br>

        <label> Message: <br><textarea cols="45" rows="6"  name="message"></textarea><br></label>

     <p>

        <button  type="submit" name="post"  value="POST COMMENT">POST  COMMENT</button>

     </p>

     <br>

  </form>

    <h2>Comments:</h2>

</body>

</html>

该表单是从test.php处理的

<?php
date_default_timezone_set('Europe/Warsaw');
?>

<!doctype html>
<html>
<head>
 <meta charset="utf-8"/>
</head>
<body>

<?php
include "contact.php";
if(empty($_POST['name'])  ||
  empty($_POST['email']) ||
  empty($_POST['message'])) {

   echo "<br><b><h3>*** Please enter all required fields ***</h3></b>";
}
else
{
  $name = filter_input( INPUT_POST, 'name', FILTER_SANITIZE_STRING);
  $email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_STRING);
  $message = filter_input(INPUT_POST, 'message', FILTER_SANITIZE_STRING);

  $datetime = date('m/d/Y h:i:s a', time());

   echo "<br>"

      . "<b>From: </b>" . htmlspecialchars( $name     )
      . "<b> at: </b>" . htmlspecialchars( $datetime)
      . "<br><br>" . htmlspecialchars( $message  )
      . "<br><hr>";
}  

?>

</body>
</html>

用户填写并提交表单后，它会显示在test.php而不是contact.php上。

为了安全起见，为什么要同时使用两个代码而不是一个代码...

我的问题是，如何将数据保留在contact.php中？

<?php  
header('Content-Type: text/html; Charset=utf-8');
mb_internal_encoding('UTF-8');
date_default_timezone_set('Europe/Warsaw');
if(isset($_REQUEST['post'])){
if(empty($_POST['name'])  ||
  empty($_POST['email']) ||
  empty($_POST['message'])) {
   echo "<br><b><h3>*** Please enter all required fields ***</h3></b>";
}
else
{
  $name = filter_input( INPUT_POST, 'name', FILTER_SANITIZE_STRING);
  $email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_STRING);
  $message = filter_input(INPUT_POST, 'message', FILTER_SANITIZE_STRING);
  $datetime = date('m/d/Y h:i:s a', time());
   echo "<br>"
      . "<b>From: </b>" . htmlspecialchars( $name     )
      . "<b> at: </b>" . htmlspecialchars( $datetime)
      . "<br><br>" . htmlspecialchars( $message  )
      . "<br><hr>";
}  
}
?>
<!doctype html>

<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

<body>
  <form  action="" method="post" name="post">
        <label for="email">E-Mail</label>
        <input type="email" id="email" name="email" />
        <label for="name">Name</label>
        <input id="name" name="name" />
      <br>
        <label> Message: <br><textarea cols="45" rows="6"  name="message"></textarea><br></label>
     <p>
        <button  type="submit" name="post"  value="POST COMMENT">POST  COMMENT</button>
     </p>
     <br>
  </form>
  <h2>Comments:</h2>
</body>

</html>

我希望这会有所帮助。

所以，“我”找到了解决方案，人们帮助了我，非常感谢他们！

我的 contact.php 文件；

<?php

 include 'Classtest.php';
 header('Content-Type: text/html; Charset=utf-8');
 mb_internal_encoding('UTF-8');
 date_default_timezone_set('Europe/Paris');

$ProveContackt=new Classtest();
?>

我的 test.php 代码；

function PostOk() {

   $data = array("name" => $name, "email" => $email, "message" => $message, "datetime" => $datetime);


   $data = serialize($data);
   file_put_contents($file, $data . "\n", FILE_APPEND|LOCK_EX);
