$_POST['username']的问题，请帮帮忙

Question

你好粗心，再看看下面的代码。
<form  action="<?php  print($_SERVER['PHP_SELF']);  ?>"  method="POST">  
                       <table>  
                       <tr><td>Username:</td>  
                       <td><?php  echo  "dddddddddd"?>  </td>  
                       <td>
   <input  type="text"  name="username"  value="<?php  if(isset($_POST['username']))print $_POST['username'];  ?>">
   </td>  
                       </tr>  
                       <tr><td  colspan="2"><input  type="submit"  name="submit"  value="submit"></td></tr>  
                       </table>  
                      
           </form>
