virtuemart reset session

Hi,

I wonder if you can help with this query. I am using j1.5, vm 1.13, metamod 2.2 (latest?)

Basically I have a recipe from you used to detect a landing page and display various modules if so. Now I have installed VM and as soon as someone goes to the VM page the session is reset so that all content is displayed.
I think this is because VM must be resetting the session - read this somewhere - but is there a way to get around it?

In case there is here is what I am doing:

[What I first tried to do was use your recipe for referrer to detect a referal link but for some reason couldn't do this as it was redirect to the site but wouldn't pick up the referring url.]

So instead I changed this by getting that url to direct to a specific landing page. That landing page has itemid=82 so i use the following recipe which you have kindly put on your site:

if ($Itemid == 82) { /* or some way to detect we are on the landing page */

session_start();

$_SESSION['LANDINGPAGE'] = true;

}

if (@$_SESSION['LANDINGPAGE']) return 63;/* replace with appropriate module id */

else {
return 62;
}

This works fine as the url is directed to a page ending itemid=82.

But as written above as soon as someone clicks onthe VM page that info is lost and all content is displayed.

Any thoughts?

PS: Thanks for a great module!

Re: virtuemart reset session

Hi britaculous,

That's an interesting problem isn't it? I wasn't aware that VM was resetting the session like that, and I'd like to understand more about it.

I wonder if this is due to the "cookie check" that VM does when you first visit a VM page? It redirects that page and sets a cookie which it then checks for (I think that's what it is). From memory you might be able to turn that off. It would be interesting to know if turning that off stops the loss of session that you are experiencing. Of course, there might be other reasons you want to keep the cookie check enabled.

Meanwhile, we could change the approach slightly to avoid using sessions entirely. Instead, we could just use a plain old cookie, set to expire in 24 hours, to simulate a "session".

e.g.

if ($Itemid == 82) { /* or some way to detect we are on the landing page */
$expire=time()+60*60*24;
setcookie("LANDINGPAGE", "1", $expire);
return 63;
}
if (@$_COOKIE['LANDINGPAGE']) return 63;/* replace with appropriate module id */
else {
return 62;
}

I haven't tested this, but it should at least avoid the session problem.

Write back if you need any more help with it...
Cheers,
Stephen
