[SOLVED] Deleting Using Checkboxes (Stuck)

[lalabored]

I'm using a flat file database and I'm trying to use checkboxes to delete data from my database but it's not working.

 

This is what my private messages database looks like... (the first part is the id of the message)

 

4tetl4xrmyux||Person Sending||Person Recieving||Subject||message||May 5 2007 at 11:41 PM||05/05/2007||

4tetl4xrmyux||Person Sending||Person Recieving||Subject||blah blah||May 5 2007 at 11:41 PM||05/05/2007||

 

My checkboxes are like this...

 

<input type="checkbox" name="pm[]" value="<?php echo $code; ?>">

 

$code is for the id of the message.

 

If I use a foreach thing like this...

 

if(isset($_POST['pm'])){
$blahblah = file("pm.php");
foreach($_POST['pm'] as $pmkey=>$pmid){
foreach($blahblah as $key=>$val){
list($code) = explode("||",$val);
if($pmid = $code){
$deleteid = $key
break;
}
}
if(!empty($deleteid) and is_int($deleteid)){
unset($blahblah[$deleteid]);
$newblah = implode("\n",$blahblah);
}
}
$fh = fopen("pm.php","w") or die("Error: Cannot open file.");
fwrite($fh,$newblah);
fclose($fh);
}

 

What's wrong with it? Because it doesn't work...

$deleteid = $key

I'm using this code now...

 

<?php

if(isset($_POST['pm'])){
$blahblah = file("data/pmsg.db.php");
foreach($_POST['pm'] as $pmkey=>$pmid){
foreach($blahblah as $key=>$val){
list($code) = explode("||",$val);
if($pmid == $code){
$wahwah = $key;
break;
}
}
if(!empty($wahwah) and is_int($wahwah)){
unset($blahblah[$wahwah]);
$newblah = implode("\n",$blahblah);
}
}
$fh = fopen("data/pmsg.db.php","w") or die("Error: Cannot open file.");
fwrite($fh,$newblah);
fclose($fh);
}

?>

 

After I click the delete button, nothing happends. No messages are deleted.

 

Also, when I do var_dump() on $newblah, it comes out as NULL. =\

When I do var_dump() on $pmid it says "string(5) "Array"", did I do something wrong?

 

Nevermind, now I have a different problem, I'm only able to delete one message at a time o.o
