[PHP] processing form with unknown number of checkboxes, each with a unknown name.

[anders thoresson]

Hi,

I building a form which will be used to set access rights to different 
parts of my web album. When editing the settings for each album, like the 
albums name and wether or not everyone should be allowed to upload pictures 
to it, I also present a list of checkboxes to the administrators. One 
checkbox for each registred user. If checked, to user is allowed to view 
the pictures, if not check, no pictures show.

The checkbox part of the form I build uses this code:

	db_connect($dbuser, $dbpassword, $dbdatabase);
	$query = SELECT userid FROM members;
	$result = mysql_query($query);
	while($row = mysql_fetch_array($result)) {
		echo($row[0]);
		?
		INPUT TYPE=checkbox name=?php echo($row[0])? VALUE=YES


But how do I process this form when saving the settings for the album? For 
the forms I've built so far, I've known what information I can find in 
$_REQUEST['']. But this time, I don't know how many checkboxes there are, 
and what their names will be. How do I do this?

Is the form ok, or is a bad form design the reason I can't figure out what 
to form processing code should be?

howabout making the checkboxes an array i.e.
INPUT TYPE=checkbox name=checkbox[?php echo($row[0])?] VALUE=YES

then when processing ...
foreach($_REQUEST[checkbox] as $checkbox)
{...
}
