can upload but not delete files

[jasonc]

i am able to upload files but when it comes to deleting them it does not work.

 

i look at the html source code before i submit or delete and all looks ok, but i echo the file name and it contains an  _  (underline) in place of the .  before the extention

 

can anyone suggest what i could be doing wrong

 

<?
$uploaddir = "/home/mysite/public_html/images/";
include("dbconfigfile.php");
if ($_POST['d'] == "1") {
foreach($_POST as $key => $val) {
if ($key != "*.*" && $key != "*" && $key != "d") {
// delete file name only from images-filename, but... if the imagelocation is empty then delete the whole entry line from DB.
//delete file from folder if exists !
unlink($uploaddir . $key);
echo($uploaddir . $key."<br><br><br><br>");
echo($key.' Deleted<br>');
mysql_query("DELETE FROM `images` WHERE `filename` ='" . $key . "' LIMIT 1;") or die(mysql_error());
}
}
echo("files are not really deleted yet, still working on it.");
} else {
?><p align="center">Please note that if you upload a file with the same name as another file you have uploaded, this new file will over write the old file.</p><p align="center">Your Existig Files...</p><p align="center">
<? $dh = opendir($uploaddir);

while (false !== ($filename = readdir($dh))) {

if(in_array($ext, $allowed)) {

}
}
?></form></p>

$file = $_FILES['imgfile']['name']; $tmp_file = $_FILES['imgfile']['tmp_name']; $size = $_FILES['imgfile']['size'];
$upload = $uploaddir . $file; $ext = getFileExtension($file);
if(!in_array($ext, $allowed)) { echo "ERROR: Invalid file extension.";
} elseif (move_uploaded_file($tmp_file, $upload)) {
// set info about image in mysql
$update = mysql_query("INSERT INTO `images` (`imagelocation` , `filename`, `uploadedby`) VALUES ('', '" . $file . "', '" . $_SESSION['adminusername'] . "')") or die(mysql_error());
echo $file."<br>Upload successfully!<br>";
} else { echo "Image upload failed.";
}
} else { echo("No file uploaded");
} ?>
