Well well well.. with the help of someone else pointing me in a
different direction altogether here's what we came up with that totally
works!
$PRODUCT_SELECTED = TRUE;
foreach($products as $value) {
if(empty($value)) {
$PRODUCT_SELECTED = FALSE;
}
last;
}
if(!$PRODUCT_SELECTED) {
$productQuery = db_query("SELECT name FROM CartTable
WHERE submitted=1 GROUP BY name");
while ($productResult = db_fetch($productQuery)) {
$products[] = $productResult[name];
}
$prod_search = "in(";
for ($i=0;$i<count($products);$i++) {
$prod_search .=
escapeQuote($products[$i]);
if ($i !=
(count($products) - 1)) {
$prod_search .=
",";
}
}
$prod_search .= ")";
$product = "AND name $prod_search";
}
else {
$prod_search = "in(";
for ($i=0;$i<count($products);$i++) {
$prod_search .= escapeQuote($products[$i]);
if ($i != (count($products) - 1)) {
$prod_search .= ",";
}
}
$prod_search .= ")";
$product = "AND name $prod_search";
}
Thanks to all for their support and help on this. Longest 4 hours of my
life :(

grrrrrrrrrrr!
Somebody else replied with isset($varname). Try that. The count()
function
is working as expected (see
http://www.php.net/manual/en/function.count.php). So maybe it's not the
best
choice for trying to find out what you want.
