What can I further do to test these Expresso Store hooks that appear to be not happening?

Question

EE 2.7.2 Store 2.0.3

It doesn't look like the hook (store_order_recalculate_end) is happening as advertised. Works fine when adding the first item to the cart. But upon cart update or adding more items, not happening.

Here is a dead simple test in my extension. (via template logging)

...
'hook' => 'store_order_recalculate_end',
'method' => 'barfoo',
...

public function barfoo(){

    $this->EE->load->library('Template', null, 'TMPL');
    $this->EE->TMPL->log_item("Hello World");

    }

What else can I be doing? Where should I be looking? This method definitely does not happen after the first item is added to the cart.

Thanks for the help.

It looks like the hooks were running, but it was more a case of the logged messages not appearing.

Store uses the Post-Redirect-Get pattern, which means that the cart is updated (and hooks run) during an HTTP POST request. When the cart has finished updating (unless there were any errors), it redirects the customer's browser back to the checkout page using a GET request (this prevents them from accidentally resubmitting the form when hitting refresh etc).

Therefore in your case the messages logged in the template library were lost when the customer's browser was redirected, hence why they weren't displayed.
