Count Image Views

I have a simple image rotation recordset for an advert image or banner:

<?php
$rsAdverts = new WA_MySQLi_RS("rsAdverts",$mysqli2,1);
$rsAdverts->setQuery("SELECT * FROM adverts ORDER BY RAND ()");
$rsAdverts->execute();
?>

In the DB table I have a INT column for "advert_views" which needs to be updated each time an image is displayed.

I would like to count the number of views for a particular image and incrementally update the "advert_views" column in the "adverts" table so that I can display this number..

Can this be done in the recordset or do I need to have some "trigger" on the page in the PHP code that displays the image that updates the table? Or both?

Update:

I tried this recordset but it causes a MYSQL error:

<?php
$rsAdverts = new WA_MySQLi_RS("rsAdverts",$mysqli2,1);
$rsAdverts->setQuery("SELECT * FROM adverts ORDER BY RAND () UPDATE adverts.advert_views SET adverts.advert_views = adverts.advert_views + 1");
$rsAdverts->execute();
?>

Thanks

You could use the MySQLi Update Record server behavior to increment the value. Use the Unique ID from the rsAdverts recordset to identify the row to update and increment the value of the advert_views. Use the "always" or "before page loads" (same thing) trigger and just make sure the update code appears below your recordset code (you will probably have to cut and paste to move it below).

Thanks
However the images are currently being displayed throughout the website as banner ads with several different sizes on each of the pages and not in a form.

Would I need to install a hidden form with the Update Record server behavior on each page that would trigger the update?

You don't need a form to trigger an update. You can just have the update code below the recordset anywhere you want the number incremented. No need for any forms or hidden form elements, just update from the recordset directly.

Ah - OK!

I tried this but it is not updating the advert_views - so I am missing the proper binding or the increment function..

<?php
$rsAdverts = new WA_MySQLi_RS("rsAdverts",$mysqli2,1);
$rsAdverts->setQuery("SELECT * FROM adverts WHERE adverts.advert_activate = '1' ORDER BY RAND ()");
$rsAdverts->execute();?>
<?php
if ("" === "") {
$UpdateQuery = new WA_MySQLi_Query($mysqli2);
$UpdateQuery->Action = "update";
$UpdateQuery->Table = "adverts";
$UpdateQuery->bindColumn("advert_views", "i", "1", "WA_DEFAULT");
$UpdateQuery->addFilter("advert_id", "=", "i", "".($_GET['advert_id']) ."");
$UpdateQuery->execute();
$UpdateGoTo = "";
if (function_exists("rel2abs")) $UpdateGoTo = $UpdateGoTo?rel2abs($UpdateGoTo,dirname(__FILE__)):"";
$UpdateQuery->redirect($UpdateGoTo);
}
?>

Thanks

You should be getting the values from the Recordset, so it would be something like:

<?php

if ("" === "") {

$UpdateQuery = new WA_MySQLi_Query($mysqli2);

$UpdateQuery->Action = "update";

$UpdateQuery->Table = "adverts";

$UpdateQuery->bindColumn("advert_views", "i", "".($rsAdverts->getColumnVal('advert_views')+1) ."", "WA_DEFAULT");

$UpdateQuery->addFilter("advert_id", "=", "i", "".($rsAdverts->getColumnVal('advert_id')) ."");

$UpdateQuery->execute();

$UpdateGoTo = "";

if (function_exists("rel2abs")) $UpdateGoTo = $UpdateGoTo?rel2abs($UpdateGoTo,dirname(__FILE__)):"";

$UpdateQuery->redirect($UpdateGoTo);

}

?>

Great. ! That works.!

I will put the entire code into an include file which can be applied throughout the website.

Yes, I was trying to figure out how to implement the "+1" in the increment code.

Now - if one could add a function for counting "Clicks" and a feature to e-mail the statistics to the users you would have a Webassist PRE-Built rotating banner application!

I learned a lot today.

Many thanks again, Ray!

I could help you implement those things. They are certainly possible to do, and not that difficult. Maybe a premier ticket to show you how. I think it would only take about an hour.

Thanks for your help and your offer. That would be really cool!

I will surely take you up on that offer as soon as I finish the current application and the client interface on the new site.
