I have this result set I am looping through. If there is nothing in
the set, I want to print out an message. Here is the code:
--------------------------
while($row = mysql_fetch_array($result))
{
$prodname = $row["prodName"];
$prodprice = $row["prodPrice"];
$pid = $row["pid"];
$photo = $row["photo"];
if(!isset($prodname))
{
print "registry is empty.";
}
//display stuff
}
--------------------------
I am not getting the print statement at all with this, even though
$prodname is blank or empty. I have tried
if($prodname == "") and if(!$prodname) but these didn't work for me.
Am I testing the wrong thing? $prodname certainly is = "" so I am
totally confused!
