If you're using Google Analytics, you can use click tracking:
<https://developers.google.com/analytics/devguides/collection/gajs/eventTrackerGuide>
I recently setup click tracking on lightbox open, close and various
other modal window bits/pieces for a metered pay wall system.
For example, within the lightbox/modal window "open" method:
[code]
// Track this lightbox instance:
window._gaq.push([
'_trackEvent', // Method.
'Paymeter Lightbox', // Group.
'Lightbox OPEN group ' + count_txt, // Append count to "action" text.
count_txt + ' OPEN event' // Prepend count to "label" text.
]);
[/code]
The advantage to using a common tool like analytics is that it's got a
ton of powerful ways to analyze the data.
Not sure the goal of your project, but I thought I would mention.
Cheers,
M

Thanks Stephen,
Nice code!
you mentioned ... - to avoid your code assuming that you will just get one
record back
But what about the case where you are deliberately just showing one record as
in ---- FIND ONE PERSON like---- where ID = 101 ?
do you still need to loop through when you just selected/displayed 1 ITEM?
Q: How do I display the columns without a loop in this 1 record case...?
these fail - so what will work?
echo $results["First"];
echo $results["First"][0]; ???
echo $results["First"][1]; ???

Have you tried chaining the the fetch() method on as in:
$pdo_object->query()->fetch();
Thanks,
Ash

echo $results[0]["First"];
