Subject: [mapserver-users] Re: php mapscript objects in session?
Hi-
I'm using ms4w 2.2.7 and I've run into a problem. Ideally I'd like
to
create the MapScript map object and store it in the session:
$_SESSION['map'] = ms_newMapObj($getMapPath);
This works fine for the that page, for the first call, but when I
attempt to reference it later I get a PHP error:
Fatal error: Object has an invalid _handle_ property
Am I missing something here?
Thanks,
-Chris
Chris,
When you attempt to start a session, you need to load the class
definition first. For example
<?php
require('myclass.php');
session_start();
?>
Hi Jim-
Thanks for responding...
Actually, I can store non MapScript objects in the $_SESSION just fine,
but when I attempt to either:
1) add the MapScript object as a private member of my class
2) simply save the MapScript object to the $_SESSION and then reuse, I
get the error.
Have you managed to store MapScript objects in sessions?
-Chris
Chris,
No I haven't saved a Mapscript object. Perhaps this is more a response
to another post that said you could only access session variables, and
not classes, from another page. However, you might try replacing
require('myclass.php');
with
if(!extension_loaded('MapScript')){
dl("php_mapscript.so");
}
There must be a way to persist a mapscript object, but I don't know enough of
OO design to tell you the answer.
Jim
