<?php
/*
category_count.inc
Provides $CATEGORY_COUNT and $CATEGORY_SIZE variables for the application.
*/
$query = "select cno, count(*), sum(pic_size_kb) from <TABLE> group by
cno";
$cat_info = mysql_query($query) or die(mysql_error());
$CATEGORY_COUNT = array();
$CATEGORY_SIZE = array();
while (list($cno, $count, $size) = mysql_fetch_row($cat_info)){
$CATEGORY_COUNT[$cno] = $count;
$CATEGORY_SIZE[$cno] = $size;
}
?>
Only problem is that you could have a slight "timing" issue where the
select above gets done, then somebody adds a new image, and then you
display your counts, and then you display the list, and that extra image
is in the list, but not counted.
You *COULD* solve this by wrapping a transaction around the whole mess if
it's really critical, but you probably don't need it.
