从mysql中删除dir和数据

Question

我使用一个上传文件到文件夹和信息（名称，大小）到数据库的表格。所以我想删除从数据库删除文件和数据的表格。

<?php
include '../dbc.php'; 
$tbl_name="image"; // Table name

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

//detect file
$directory  = "../../Upload/"; 
$images = scandir($directory);
$ignore = Array(".", "..");
?>

 <table width="800px" style="background:white;margin:50px auto; font-size:13px;" border="1" cellpadding="3">
          <tr>
          <td colspan="3"><strong>Delete:</strong> </td>
          </tr>

          <tr>
          <td width="40%" align="center"><strong>Name</strong></td>
          <td width="10%" align="center"><strong>Size</strong></td>
          <td width="5%" align="center"><strong>Delete</strong></td>
          </tr>

          <?php
          while($rows=mysql_fetch_array($result)){
          ?>
          <tr id='del'>
          <td><?php echo $rows['name']; ?></td>
          <td><?php echo number_format($rows['imgSize'], 2) ?> MB</td>
          <td><a name="delete" href="delData1.php?id=<?php echo $rows['imgId']; 
           ?>">Delete</a></td>
          </tr>

          <?php
          }
          ?>

          </table>
          <?php
          mysql_close();
          ?>

delData1.php

<?php
include '../dbc.php';
$tbl_name="image"; // Table name
// get value of id that sent from address bar
$id=$_GET['id'];

$filename = $_POST['filename'];
$path = $_POST['directory'];
if(file_exists($path."/".$filename)) { 
 unlink($path."/".$filename); //delete file
}

// Delete data in mysql from row that has this id
$sql="DELETE FROM $tbl_name WHERE imgId='$id'";
$result=mysql_query($sql);

// if successfully deleted
if($result){
    rmdir('$name');
echo "Deleted";
echo "<BR>";
header("Location:Data.php");
}

else {
echo "ERROR";
}
?>

它从数据库中删除数据，但文件保留在文件夹中。
