[FX.php List] Shopping cart question

[Gjermund Gusland Thorsen]

loading an array is done as the following:

$_SESSION['cart'][] = $_POST['recidOfCurrentlyAddedProduct'];

Note [] will add a new row in the array $_SESSION['cart']

if( $r['foundCount'] > 0 ) {
	foreach( $r['data'] as $key => $value ) {
		list( $recid, $modid ) = explode( '.', $key );
		foreach( $_SESSION['cart'] as $v ) {
			if( intval( $v ) == intval( $recid ) ) {
				$disabled = ' disabled';
			} else {
				$disabled = '';
			}
		}
	}
} else {
	$output = 'nothing... perhaps improve your search criteria?!?';
}
