Taking out the numbers from links

Is there an easy way taking out the numbers from the links?

Instead of this:
https://www.domain.com/catalogue/category-c-11/sub-category-c-40/sub-sub-category-c-39/

to show this:
https://www.domain.com/catalogue/category/sub-category/sub-sub-category/

See the add-on [url=https://www.litecart.net/en/addons/162/permalinks]Permalinks[/url]

Ok. Ive installed this to V 2.5.5
Works ok, however

The link I get is:
https://www.mydomain.com/my-custom-name?category_id=20

why is the ?category_id=20 there?
is there a way this can be removed or its important to have that there?

as the page opens just fine like this, too:
https://www.mydomain.com/my-custom-name

As far as i know, the [b]category_id=20[/b] in your url is needed to read the id of the category with $_GET
look below: it's reading the category_id with the $_GET['category_id']

You need to setup permalink for every category or product manually with this addon.
Open category edit page and write a custom permalink in there.

@jackmaessen is right. Without category_id we can't refer back to the tree navigation.

There is a topic regarding removing the category_id using the Permalinks addon.

@dodo I think this is category urls he is referring to.

I see. Thank you.

Since I use the Permalinks addon, and handling hundreds of pruducts, I would like to echo the permalink after each product and category, when I go to admin > catalog

I will than see the permalinks under each other, noticing if there are duplications or if there are products that we missed adding a permalink.

How to achieve this?

Isn't the permalink field in the latest lc_permalinks already a unique field?  If not, maybe it should be?  I remember running into a duplication problem myself awhile back.  Don't remember how I solved it now.  : \

I cant see this in 2.6.0 - I think it still has to be installes in Vmod

@s22_tech Permalinks is an add-on.

@cyber83 To echo a permalink try echo reference::product($product_id)->permalink[language::$selected['code']] where 'en' is the language code.
