Checkbox mail deleting

[Undrium]

I have two questions, never been working with checkboxes this is why I'm puzzled.

Anyways:

1. Can you put a variable into a $REQUEST[''] field? For instance $REQUEST['$index']?

2. The following code is supposed to delete the messages the user wants removed. He or she marks a checkbox/several checkboxes and presses 'delete'. This code is supposed to read all the checkboxes data coming in (I've limited the max amount of mail to 100). $duser is a session variable.

// Check if user really is the user who wants to delete comment
	$a=0;
	while( $a <= 100 ){

$id = $_REQUEST['$a'];
$result = @mysql_query("SELECT tuser FROM pm WHERE id = '$id'"); 
$userfetch = mysql_fetch_array($result);
$user = $userfetch['tuser'];
$a++;
	if ($user == $duser) { 

		// Delete thread

     	@mysql_query("DELETE FROM pm WHERE id ='$id'");

		mysql_query($sql2);			
	}

}

Pardon the bad format. :rolleyes:

Also sorry about my English, it's not my native language. Hope someone could help me out with this.

1. The single quotes make the $a be interpreted literally instead of as a variable. Use $_REQUEST[$a] instead.

2. Instead of checkboxes named 1 to 100, personally I'd use an array (<input type="checkbox" name="deletethese[1]"> etc in the form) and then instead of the while loop do a

   if (is_array($deletethese))
   {
    foreach($deletethese as $id)
    {
   ...
    }
   }
   

   That way it's not limited to 100. (I don't see how it's practical to keep mysql id numbers from going over 100, just limiting the mail at any one time to 100 won't do it.)

Hoth: The id number is never limited to 100, it's the amount of PMs. The checkboxes are named from 1-100. 🙂 Thanks alot for the help, it's really appreciated.
