The use of function header() is forbidden

[SergMi]

Hello,

In my module i use next code

header('Content-Type: application/json');

Received the following comment from prestashop team

The use of function header() is forbidden; use Tools::redirect() or Tools::redirectLink() instead header('Content-Type: application/json');

Tell me how to properly replace this line on Tools::redirect()

Thank you in advance

Of course, you can't change the header of the page, can you tell us what are you trying to do?

Yes, of course this line used for module "Compare"

This used for action add, remove or remove all products
Example of use function with "header'

 

 public function processRemoveAll()
    {
        header('Content-Type: application/json');

        $productsIds = array();
        $productsIds = Tools::jsonEncode($productsIds, true);
        $this->context->cookie->__set('brilliantCompare', $productsIds);
        
        $this->ajaxDie(Tools::jsonEncode(array(
            'success' => true,
            'data' => [
                'message' => $this->module->l('All products removed','actions'),
                'type' => 'removedAll',
                'view' => $this->module->l('View compare','actions')
            ]
        )));
    }

Ok, you need call it from an external call, not inside the module,  or by ajax.

Sorry, but I'm a novice developer, could you please explain in more detail what needs to be done.

Thank you in advance
