Getting current category with FPC enabled

Is it possible to get current category when Full Page Cache is enabled? Catalog controller is not executed in this case, so the registry (current_category key) is empty. All I can get is the root category

Thank开发者_如何学运维s

As one of the possible solution is to get category ID by given url. You have table of url rewrites and you have request string.

    // Try to get category id directly from request
    if (Mage::app()->getRequest()->getParam('id')) {
        return Mage::app()->getRequest()->getParam('id');
    }
    // Try to get category id from request by rewrite request path
    $aliases = Mage::app()->getRequest()->getAliases();
    if ($aliases && is_array($aliases) && !empty($aliases) && $aliases['rewrite_request_path']) {
        $urlRewrite = Mage::getModel('core/url_rewrite')->loadByRequestPath($aliases['rewrite_request_path']);
        if ($urlRewrite && $urlRewrite->getId()) {
            return $urlRewrite->getCategoryId();
        }
    }

May be it's not beautiful solution but it worked well for me.

You need to get it via the layer:

$layer = Mage::getSingleton('catalog/layer');
$_category = $layer->getCurrentCategory();
$currentCategoryId= $_category->getId();

You are hole punching your block as indicated here:

I'm writing a module with random products list block, it's not affected by FPC by implementing hole punching

This means that your block is a stripped down version of Magento (see applyWithoutApp() method), so to access the current_category out of the registry, you'll need to register it in your Container in your hole punch module.
