unlink files that are checked

jlory

I want to use the unlink function to delete files who's checkbox is checked. Below is the code I am using, which is not working. I know I'm probably way off here...... Has anyone done this before???

Thanks,

Jamie

<?
$dh = opendir('upload');
while($file = readdir($dh)) {
//if $file == '.' or == '..' skip it
//and if file extension == '.php3' or '.php' or '.phtml' make a link to $file
if($file != '.' && $file != '..' && ereg(".(php3|php|phtml|doc|wk4|xls)",$file)) {

echo "<INPUT TYPE=checkbox NAME=checkbox value=\"$checked\">  <A href=/construction/upload/$file>$file</A>\n";

print "<br>";

}
}

for ($i=0;$checkbox[$i]!="";$i++)
{
if(isset($delete))
{

$delete = "/home/httpd/html/construction/upload/$file";

   unlink("$delete where $file=" . $checkbox[$i] );
   }
}
