Magento 2 - Check if category exists or not

Question

I need to check if category exist or not by category name.

I have try this with category name test but it does not work at the same time it does not throw any error

$category = $this->_objectManager->create('Magento\Catalog\Model\Category');

$cate = $category->getCollection()->addAttributeToFilter('name','test')->getFirstItem();

if (!isset($cate)) {
    echo "not exist";
} else {
    echo "already exist";
}

how to deal with check if category exist or not?

Thanks

Answer 1

use $cate->getId() it give false value when category does not exit

if (!$cate->getId()) {
    echo "not exist";
} else {
    echo "already exist";
}

Answer 2

please make change in if condition as below:

if ($cate->getSize() > 0) {
    echo "already exist";
} else {
    echo "not exist";
}

above code should give you the desired result..

And I would recommend you use Constructor Injection to get the collection rather than creating it into object manager...

hope this will work...
