Elisabeth,
It's quite as simple as the session handling. You can split your code into many
files or keep it in one single file,
the only thing you have to know is that PHP's session_start() function call must
be the first thing wrote, no
HTML or PHP code before that.
Cheers from México
IC Carlos Ruiz

Hello Mr. Sumariva, i already did wht u said, but there's new error: error:
Call to undefined function: on_get_contens() in
I:\ms4w\apps\appweb\htdocs\index_cobacham.phtml on line 2
here i put the cobachanphtml.phtml:
<?php
$html=on_get_contens();
ob_end_clean();
include("./chameleon.php");
$szTemplate="./template_werror.html";
$szMapFile="../map/kelur_cobacham.map";
class SampleApp extends Chameleon //SampleApp merupakan turunan dari
Chameleon
{
function SampleApp() //Nama fungsi
{
parent::Chameleon(); //Menjalankan konstruktor class Chameleon
$this->moMapSession=new MapSession_RW; //Mbwt instance obj map
session
$this->moMapSession->setTempDir
(getSessionSavePath()); //Mendefinisikan dir temporer yg akn digunk olh
obj map
session
}
}
$oApp= new SampleApp(); //Membut instance obj SampleApp
$oApp->registerSkin('skins/sample'); //mendefinisikan skin utk obj SampleApp
$oApp->CWCInitialize($szTemplate, $szMapFile); //MEnginisialisasi obj Lat01
dg file template dan file
.map
$oApp->CWCExecute(); //Menjalankan app dg memangil fs CWCExecute
?>
So, what should i do?
Thanks a lot for the attention, sorry reply not direct.

Well, you can turn the things by other way.
Put at top of HTML file in the ob_start() function to tell PHP to buffer all
output.
Change your your index_cobachan by adding
$html = ob_get_contens();
ob_end_clean();
Now all the content that would be sent to browser is available at $html string
variable.
After the includes in your index_cobachan print the contents of $html var.
Now do your application logic.
THen append the rest of HTML file.
Another option is to turn your HTML file into a template and add a special mark
to signal template engine to replace some content but this would be another
aproach.

Thanks Mr.Sumariva for the advice but, session_start() in the page already embed
in Chameleon framework at its folder in \htdocs\common\session
