display ads in password protected pages

Hey guys, just want to ask how to get correct ads displayed in my password protected pages.

I want to display ads on my members area pages, there are ads displaying but not relevant to the content of the pages and some times no ads.

I have seen sites with members area displaying adsense ads related to the page content

 

When my site was young, those wnet wrong for me to. So I tunred them off.

However there came a time, much later, that I put up an ad that showed in private forums. The general topic was used for the ads. I was pleased.

So I dunno if that helps or if there are better ways, but that was my experience.

 

I tried this on

function robot()
{
global $HTTP_USER_AGENT, $REMOTE_ADDR;
if(stristr($HTTP_USER_AGENT,"Mediapartners-Google/2.1")) return true;
}


if(robot())
{
echo "
Text that is related to the page content here
";
}
else
{
//if not a robot... then require to logon...
include "log.php";
}

 

excellent trick

 

Great work PinoyIto. A cool piece of code..
