调用上传文件

Question

In html I have an upload button for a photo:

 <p>
   <input type="file" name="datafile" size="40">
 </p>
 <br>
 <p>
 <input type="submit" name="submit" id="submit" value="submit" />
  </p>

After that I want to take the results using the echo and insert the result in a table in the center of page.

I made this but it is not working properly. Any suggestion?

  <table align="center">
  <tr>
      <?php echo $_POST['datafile']; ?>
    </tr>
  </table>

You should have enctype="multipart/form-data in your form tag

<form action="upload.php" method="post" enctype="multipart/form-data">

And get the uploaded file via $_FILES: http://www.w3schools.com/php/php_file_upload.asp
