Is there some way to trigger adding a specific product to an open cart?

[David R]

Thanks for reaching out, I did start with him. He's great.

But for now, anyway, he doesn't have any one thing or combination of things that does this.

I was hoping someone had successfully executed the example they give in the developer's area, because I'm not a developer and it takes me so long to work my way through learning what I need to know to get one specific thing done... :-)

But I'm guessing that since nobody -- not even thatsoftwareguy -- has done it, there must be some real hurdles.

These forums have saved me countless times, so I haven't given up hope!

Judging from http://www.thatsoftwareguy.com/zenca...o_bonanza.html it seems the majority of what you've said is indeed available with his plugins. Which specific feature is missing? Perhaps it's more prudent to supplement with something that specifically handles the missing requirement than writing everything from scratch.

Thanks Dr. Byte, I thought so, too. But we corresponded about it a bit, and the upshot is that nothing he's currently got will address these things:
a) add a product "Y" to the cart when two products of some type are purchased
b) remove an item from the cart if the buyer changes cart contents and no longer qualifies.

Do you know if anyone ever pushed that tutorial example far enough to know it will work? Has something in the 1.5x generation of Zen Cart made it not a good option?

Thanks again,

I know I did, years ago. Not sure if I still have that code around anyplace.
It's very challenging to also have an Admin interface to manage all the possible options. What I'd done was all handled in a PHP file, without any admin-side controls about what products qualified with other products etc. Very rigid implementation. But certainly doable. If you want nice admin controls and switches and fancy dialogs you'll be needing to invest more to provide that.

Note, too, that the example should be updated to show the use of the __construct function (that's going to be needed for PHP 7.0 compliance), e.g. changing references like:

<?php
 class myObserver extends base {
   function myObserver() {
     $this->attach($this, array('NOTIFIER_CART_ADD_CART_END'));
   }
...
 }

to

<?php
 class myObserver extends base {
   function __construct() {
     $this->attach($this, array('NOTIFIER_CART_ADD_CART_END'));
   }
...
 }

Good point. Updated. Thanks.

Good point. Updated. Thanks.

Thanks very much!

We don't need any admin interface component to this, and I can repurpose some of the dialog functions we use now. I'll try to get it working from the tutorial as it stands, so I don't introduce any new troubleshooting issues with the __construct function for now.
