incrementing..?

[JD_]

i cant seem to get my head round this one.

$numresults = mysql_query("SELECT * FROM products where prod_ID like $ID_RES"); // the query. 
$numrows = mysql_num_rows($numresults); // Number of rows returned from above query.

if ($numrows < "0") { $pic_num = "1"; } else { $pic_num = $numrows++; } 
echo "pic number is $pic_num";

i want it to check if theres products if there isnt $pic_num wants to be 1 and then next time it would 2,3,4,5 etc...

i fixed it with $numrows + 1 instead of $numrows++ though i thought there supposed to do the same thing?

You were using post-increment. Pre-increment should work: "++$numrows" (if I follow correctly what you're trying to do).

Thanks!

Now I'm not sure I do. How would "$numrows" be less than 0? Is this what you mean to do:

if ($numrows === false) { 
    $pic_num = 1; 
} else { 
    $pic_num = ++$numrows; 
}  

echo "pic number is $pic_num";

And what do you mean by "next time"?
