How can you get the category ID of “category-name” from a nice URL (e.g. http://www.example.com/category/category-name/)?
I need to retrieve the category ID from a URL of wordpress because this function will be used in wp_nav_menu() since the design of the site is to have a dropdown of latest post under the category, so if it is not a category of wordpress (link to home page or about page), then there should be on dropdown.
I found this site(http://ditlo.com/) to be an example of the problem 🙂
Try this,
Reference http://codex.wordpress.org/Function_Reference/get_category_by_path
You will want a couple of steps:
get_category_by_slug( $slug )– Call this with the URL fragment (the slug) as an arg, and it’ll give you a category object.$category->cat_ID– Call this on the$categoryobject to return the ID of the category.A one-liner would look like:
$slug_ID = get_category_by_slug($slug)->cat_ID;
