$_POST within function

[anakadote]

im stumped - in a previous function, $_POST returns a value, in this is does not:

function updateGal($number, $now){
if(isset($POST['update' . $number])){
$query = "UPDATE gallery SET title" . $number . "='{$POST['title" . $number . "']}', date" . $number . "='{$POST['date" . $number . "']}', medium" . $number . "='{$POST['medium" . $number . "']}', dimen" . $number . "='{$POST['dimen" . $number . "']}' WHERE mem_id='{$SESSION['mem_id']}'";
$result = mysql_query($query) or die(mysql_error());

etc...

$query echos as: UPDATE gallery SET title7='', date7='', medium7='', dimen7='' WHERE mem_id='050101

any help appreciated?

Ive never used post that way, But isset wont check if the var is empty, it doesnt see "" as NULL, So you might want to:

if (isset($_POST['moo']) && (empty($_POST['moo']) == false)

{

Or something to that effect..

true, but i know that it exists, otherwise, isset($_POST... would be false by default.

Yes, isset will pass "" in a post, That may be why your select query is empty

You have an error in those $_POST thingies..

You have:
{$_POST['title" . $number . "']}

Should be:
{$_POST['title' . $number]}

You have that on all those.
