[Aaron Wolski]

Argh !!!!!!!!
 
 
HOW does one check for an array being empty from a form field??????????
 
Tried a billion different things and NOTHING works!!!!
 
I've tried:
 
if ($products == "\n") {
 
echo "hello";
}
 
else {
 
            echo "bye";
 
}
 
 
if ($products == "") {
 
echo "hello";
}
 
else {
 
            echo "bye";
 
}
 
 
 
if (empty($products)) {
 
echo "hello";
}
 
else {
 
            echo "bye";
 
}
 
 
if (!isset($products)) {
 
echo "hello";
}
 
else {
 
            echo "bye";
 
}
 
 
if (count($products) == 0) {
 
echo "hello";
}
 
else {
 
            echo "bye";
 
}
 
 
NOTHING works!!!
 
Any help.. puuulease?
