Hi uglykidjoe,

Welcome to the world of JomGenius! It's easier than you think.

If you use $vm->info( "cart_product_ids" ) then as you have seen, you get an array. If you want to use this in PHP, that's fine. But JomGenius has much easier ways of checking for particular values.

If you want to check that array for 1 or more specific values, then use:

if ( $vm->check( "cart_product_ids = 132, 134, 133" ) ) echo "found one!";

If you want to check to see that the cart contains one of these 3 products, use this:

if ( $vm->check( "all of cart_product_ids = 132, 134, 133" ) ) echo "you are purchasing 132, 133 and 134!";

That last rule has interesting logic. JomGenius takes to mean "every item in the array on the left has to equal at least one of the items on the right". This is a good example of when this is useful.

If you want to check that a specific product is NOT in the cart, use this:

if ( $vm->check( "all of cart_product_ids = none of 132, 134, 133" ) ) echo "you are not purchasing any of 132, 133 or 134";

(i.e. it checks through every item in the cart to make sure it matches none of the items in the list on the right)


Ok, that's probably overkill. You probably just want to use the first one, to trigger when any of the mentioned products are in the cart.

Cheers,

I think this is going beyond what you should be doing with MetaMod! By the time MetaMod is viewing this information, the product will already have been added to the cart, so there's no way that MetaMod can actually remove it from the cart, or prevent it from going in, in the first place.

Sorry, I think you need to find a way to do this deeper inside Virtuemart (though I think this will be very difficult unless you can find a VM genius to code it).

Cheers,
Stephen

Hmmm... maybe.

so which types of pages should people not be allowed to visit once the cart contains 132 AND 133 AND 134?
- no product pages at all?

So you could do that like this:

$vm = JomGenius("virtuemart");
if ( $vm->check("pagetype = shop.product_details")
and $vm->check( "cart_product_ids = 132" )
and $vm->check( "cart_product_ids = 133" )
and $vm->check( "cart_product_ids = 134" ) ) {
  $app = &JFactory::getApplication();
  $app->redirect("http://www.example.com/YouCantBuyThat.html");
}


This does pretty much as it reads: it checks to see if the person is going to a product details page. If so, and if 132 and 133 and 134 are already in the cart, then it redirects to the other page.

I never imagined anyone would want to do this!!! But it should work.

Cheers,

Thanks, but not quite there - really need 'or' rather than 'and' logic

Once product 132, 133 or 134 have been added nothing else can be added to the cart unless its also 132, 133 or 134 if you see what I mean.


Thanks Steve
