[FX.php List] Beating a dead horse (was: trying to read back an array)

[Joel Shapiro]

Hi Bob

You might have figured this out already, but here are some thoughts of  
mine:

What's the session array supposed to be capturing?  Is it individual  
items that need service, with data specific to each of those items  
(serial, type, description, etc)?

Are users sending more than one item per POST?  What does the  
$_POST['recid'] array look like?  And if recid's are in an array, why  
doesn't the other data come in with them in the same array (it looks  
like they come in as $_POST['description12'],  
$_POST['description213'], etc.)

I think the goal would be to end up with a $_SESSION array like this,  
containing an [item] array ($_SESSION['item']):

Array
(
	[item] => Array
	(
		[12] => Array
		(
			[description] => pen
			[type] => ballpoint
			[problem] => doesn't click
			[serial] => 42X5W
		)
		[213] => Array
		(
			[description] => pen
			[type] => quill
			[problem] => leaks
			[serial] => 35LL53W8
		)
		[569] => Array
		(
			[description] => iPod
			[type] => Nano
			[problem] => too loud
			[serial] => UR3298
		)
	)
)

For setting this up, I'd do the following for each item that comes in  
via POST:

$_SESSION['item'][$recid] = array(
	'description' => $_POST['description'.$recid],
	'type' => $_POST['type'.$recid],
	'problem' => $_POST['problem'.$recid],
	'serial' => $_POST['serial'.$recid]
	);


HTH,
-Joel
