Question

I’m creating eBay style search panes that allow users to narrow their results set by certain criteria. For example:

Tags

Literature (8)
Fiction (4)
English (4)
American (3)
Non-fiction (2)

The number of results which have that property is in brackets. Initially, I built the counters by putting this code in my display results loop:

if(isset($tags[$row['tags']])) {
    $tags[$row['tags']]++;
} else {
$tags[$row['tags']] = 1;
}

Then I paginated my results and that stopped working – the query only returns enough data for the page you are on, so the counters only represent the results on that page.

Can anyone suggest another approach?

Answer 1

You’ll have to run a second query for tag, COUNT(*) in <table> GROUP BY tag to get total numbers for each tag.

edit:

Check this out. This is a new one by me, but it looks like what you want.

Start your query with SELECT SQL_CALC_FOUND_ROWS, then follow up your query with SELECT FOUND_ROWS();
