[FX.php List] Trying to read back an array

[Leo R. Lundgren]

You are setting this:

	$_SESSION['description['.$recid.']']

And then trying to fetch it like this:

	$_SESSION['description'.$recid]

Those two expressions are not the same, so you don't get any data back.

Have you looked at your PHP error log (with Apache this is by default the error_log file)? There's probably a ton of errors in there :)

The part:

	if( (strlen($_POST['recid'])>0) && (is_array($_POST['recid']))) {

is better off like:

	if( isset($_POST['recid']) && is_array($_POST['recid']) ) {

No need for those extra () (but they don't hurt!), and first checking if the *string* length of a variable is > 0, and then checking if the variable is an *array* doesn't add up.
I'm guessing you want to see that the variable is set and that it is an array, that's what the code above does :)
The thing is that apart from the "double" type comparison, you'd get a bunch of warnings in the error log if $_POST['recid'] isn't set.
