When I use that, here:
if ($num_pages >= 2) {
for ($i=1; $i<=$num_pages; $i+=20) {
echo "$i";
}
}
I get 1, or whatever I set $i= in the first expression. No other iterations.
When I use Craig's way, it works - kinda. Based on what I'm using this code
in, I should get two iterations. I'm counting the number of rows from my DB,
dividing it by 20, that's the number of pages I have - currently I have 22
records, so 2 pages. Here's what I use for that:
$sql = mysql_query("SELECT * FROM table");
$num_rows = mysql_num_rows($sql);
$num_pages = ceil($num_rows/20);
So why would I only get 1 iteration? 22/20 = 1.2 rounded up to 2. This
satisfies the if ($num_pages >= 2) statement and initiates the loop. $i
starts as 1, then should loop once more. If I set $i=0, I echo 0. What
gives?
I may not be able to answer anymore tonight, have to DJ for 4 hours
beginning in about 35 minutes, so I need to get ready for that, but
certainly anymore ideas would be great. Thanks!

Hi
What you need is
for ($i=1; $i<=$num_pages; $i+=20) {
// print stuff here
}
