Hi,
I haven't tested this.It should work..try
Write this function in the begining of each page or save it in some file and include that file in each page.
function loadPage($page)
{
echo "<SCRIPT language=\"javascript\">\n";
echo "function loadNew(){\n";
echo "parent.frame1.location=\"$page\"\n";
echo "}"\n";
echo "</SCRIPT>\n";
}
Call this function in the head<HEAD></HEAD> part of the page and you need to pass the page you want to display in the first frame as an argument.
On body(<BODY>) onLoad() event call the javascript function loadNew()
i.e <BODY onLoad="loadNew()">
Hope this works
Cheers
Ajay
