How can i get current category in magento2 ?
I want to get category name and category id in custom phtml file.
The above to seem correct, but I think that jumping straight to the Registry is not the best approach. Magento provides a Layer Resolver that already encapsulates that functionality. (See the TopMenu Block in the Catalog Plugins)
I suggest injecting the \Magento\Catalog\Model\Layer\Resolver class and using that to get the current category. Here is the code :
<?php
namespace FooBar\Demo\Block;
class Demo extends \Magento\Framework\View\Element\Template
{
private $layerResolver;
public function __construct(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Catalog\Model\Layer\Resolver $layerResolver,
array $data = []
) {
parent::__construct($context, $data);
$this->layerResolver = $layerResolver;
}
public function getCurrentCategory()
{
return $this->layerResolver->get()->getCurrentCategory();
}
}
Here is what the actual getCurrentCategory() method does in the Resolver Class.
public function getCurrentCategory()
{
$category = $this->getData('current_category');
if ($category === null) {
$category = $this->registry->registry('current_category');
if ($category) {
$this->setData('current_category', $category);
} else {
$category = $this->categoryRepository->get($this->getCurrentStore()->getRootCategoryId());
$this->setData('current_category', $category);
}
}
return $category;
}
As you can see, it does still use the registry but it provides a fallback in case that fails.
