Subcategory URL

I am trying to implement the following URL structure /section/category/sub-category/ I had a quick play with gbp_permanent_links, but as far as I can see it doesn’t allow for nested categories in the URL.

Does anyone have any experience with this?

Re: Subcategory URL

Don’t know if you could get it to work by using /section/category1/category2/? Of course in that case the parent should always be category1 and the subcategory category2…

(Aside: questions about plugins are better asked in the plugin thread.)

Re: Subcategory URL

Thanks Els—very true, I posted in the plugin thread as well now. However, I was wondering more whether there are any other solutions other than the gbp_permanent_links.

The problem with category1 and category2 is that they only become 1 and 2 once they are applied to an article. It is pretty much irrelevant for category listings.

Yes, I know, but that’s probably the reason why gbp_permanent_links won’t be able to handle this: it would somehow need to find the parent to an article’s category. Don’t know if you have many categories, but it might be possible to set up a permanent link rule for each category, and enter the parent as plain text.

Re: Subcategory URL

Something a little different: Is there a way to find out whether a category has any children?

I tried <txp:variable name="if_cat_children" value='<txp:category_list section="portfolio" parent='<txp:category />' wraptag="" break="," exclude='<txp:category />'><txp:category link="0" title="0"/></txp:category_list>'/>, to then check whether the variable is empty—however, it always is empty even when it should contain the names of some subcategories.

Try this (tags in tags in tags need two single quotes…). I don’t think the section attribute is doing anything in this code, so you may as well remove it.

Re: Subcategory URL

Thanks! Actually I just looked at your hasarticle txptip and saw the two ‘’ myself. Not entirely sure why, but it works…
