Save data created in OpenCart 2.3 event for later display

Question

I see how to use an event to generate a controller call in OpenCart 2.3.

What I don't see is how to save the data created by the controller call for later use in a view.

How have other people handled this?

Not sure exactly what you want to do here but couldn't you just do something like:

file_put_contents(DIR_CACHE . __CLASS__ . __FUNCTION__ . md5(serialize($this->request->get)) . '.ser', serialize($data));

That would store everything in $data (which is everything that gets passed to the view) in a flat file named after the class and method and query parameters.

Then, for example, to recall later on a product page, just do:

if (file_exists(DIR_CACHE . __CLASS__ . __FUNCTION__ . md5(serialize($this->request->get)) . '.ser') {
    $data = unserialize(file_get_contents(DIR_CACHE . __CLASS__ . __FUNCTION__ . md5(serialize($this->request->get)) . '.ser'));
    $this->response->setOutput($this->load->view('product/product', $data));
}

Not sure if that answers your question but could could also just use Opencart's built in cache methods if you wanted it to expire at regular intervals.

If two users visited the same store at the same time, one would overwrite the other's cache data. — Scott C Wilson, Aug 03 '17 at 15:56
not necessarily. that would depend on how and when you decide to write to the cache which is beyond the scope of what he asked — But those new buttons though.., Aug 03 '17 at 20:49
OK - "would" should have been "could". Since this is a risk, it wouldn't be a good choice for the web. If this was a desktop situation, yes, what you're suggesting would work. — Scott C Wilson, Aug 03 '17 at 21:03
