Hey,
Thanks for replying.
That means I will have to run a query per categorywhich I would like
to
avoid if possible as they could be
a high amount of categories as they are user created and not defined by
us.
?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.
Thanks,
Ryan

run another sql query:
select pic_size_kb from table where
pic_category='$current_category,
then make a loop that increments a)
the total number of records (ie total number of pics in category), and
then adds the pic size from each record to some variable (eg
$total_kb) and then you have your total.
hope that helps.

[PHP] Count totals (might be 0T)
Hi again, Am faced with a new problem (either that or working straight 10 hours is catching up!) Heres my table (easy to figure out so i wont waste your time explaining the fields): cno, date_added, pic_name, pic_size_kb, pic_desc_text, pic_category the way i am displaying the data is like this (thanks to Phillip and Andy from this list) __ category here 2pics, 90kb | - | pic-here | pic_desc_text | | pic-here | pic_desc_text | __ category here 2pics, 160kb | - | pic-here | pic_desc_text | | pic-here | pic_desc_text | - When I sql the DB I call it like this: select picture_name,more fields from table where cno=x order by category. Any ideas as to how i get how many pics per category and size per category? I'm not sure if its a PHP thing or a MySql thing... Last problem for the day...then i hit the sack!

Any ideas as to how i get how many pics per category and size per category? I'm not sure if its a PHP thing or a MySql thing... By either running a query for each category grabbing the data you want. Or by grabbing the data you want in the initial query and adding it all up BEFORE you start to do you display logic. So the second option would be: 1. Get all the data. 2. Loop through all the data creating the tally(s) you want. 3. Loop through the data again creating your visual gropings and throwing in the tally(s) you created earlier. Try both options and time them. Chris. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
