Get the id_product param while edit a product inside the hook displayBackOfficeDisplayHeader

[PrestaEdit]

Hi there !

Can you tell me how I can have the "id_product" inside the hook "displayBackOfficeDisplayHeader" when I edit a product on the PrestaShop 1.7 version, maybe ?

Hi Jonathan,

I think in a module, a simple Tools::getValue('id') should do the job just fine.

We considered $request = Request::createFromGlobals() or the snippet you sent me by email but we think there is no point. If there is no container, using the good old way is fine :)

What do you think?

It was I expected... But isn't work, for sure (it's why I have created this issue, because the old way doesn't seems to work there). ;-)

[julienbourdeau]

Sorry we got a bit confused! Indeed the id is extracted from the URL by the routing component but it isn't in $_GET nor $_POST. It's an attribute in the request.

Hence your snippet was the best way to achieve that, well done! :)

For reference:

global $kernel;
$request = $kernel->getContainer()->get('request');
$idProduct = $request->get('id');

I'll reopen since it needs documentation.

Hi @julienbourdeau

We are not supposed to use global into modules as it's forbidden into the validator. By the way, I would prefer (and it would keep BC) keep using Tools::getValue().

Tools::getValue method would use the kernel to retrieve the request and return the needed data when we are on a symfony controller.

What do you think ?

[julienbourdeau]

To "avoid" globals, you can use $request = Request::createFromGlobals() instead.

The very best way would be making the request available in hooks! We'll discuss this today and we'll let you know.

Thanks for your detailed feedback.

If i remember well, $request = Request::createFromGlobals() does not include parameters (id of product). About making request available in hooks, it's fine too, but if we can keep some BC using Tools::getValue()... That is fine too !

You remember well, @prestamodule. The $idProduct will be null if you use the Request call.
