Deleting Files From a Directory

[mdversion1]

I have this script that lists the files in a directory nicely with checkboxes to remove unwanted files but when I click the "Remove" button nothing happens. It won't delete anything. I think the problem lies in the array that unlinks the files. Any help is greatly appreciated.

 

Here's the code:

 

<?php

 

// change this to your path (NO TRAILING [ / ])

 

$dir = "/path/to/dir/files";

?>

 

 

<form action="view_image_list.php" method="post">

<table border=0 cellpadding=2 cellspacing=0 width=380 align=center>

<tr>

<td width=40 align=center valign=middle bgcolor=336699 nowrap height=21>

 </td>

<td width=240 valign=middle bgcolor=336699 nowrap>

<font size=2 color=FFFFFF><B>File Name</B></font></td>

<td width=80 align=center valign=middle bgcolor=336699 nowrap>

<font size=2 color=FFFFFF><B>File Size</B></font></td></tr>

 

<?php

 

// Unlink Array

if ((submit)&&($fid != "")) {

foreach($fid as $rfn) {

$remove = "$dir/$rfn"; 

unlink($remove);

}

}

 

// List Files in Directory

$handle=opendir($dir); 

while (($file = readdir($handle))!== false){ 

    if ($file != "." && $file != "..") {

$size = filesize("$dir/$file");

$list .= '<tr><td width="40" align="center" valign="middle" bgcolor="93BEE"2 nowrap height="21">';

$list .= '<input type="checkbox" name="fid[]" value="'.$file.'"></td>';

$list .= '<td width="240" valign="middle" bgcolor="93BEE2" nowrap>';

$list .= '<font size="2" color="336699">'.$file.'</font></td>';

$list .= '<td align="center" width="80" valign="middle" bgcolor="93BEE2" nowrap>';

$list .= '<font size="2" color="336699">'.$size.' Kb</font></td></tr>';

    } 

}

closedir($handle);

echo $list;

?>

<tr>

<td colspan="3" align="center" valign="middle" bgcolor="336699" nowrap height="21">

<font size="2" color="FFFFFF"><input type="submit" value="Remove"></font></td></tr></table>

</form>
