How to Get Category Slug Using Category ID!

When styling your WordPress theme files, you may come across times when you may wish to display your WordPress Category slug ( category name ). We can easily achieve this task by using the Category ID.

In one of my recent works, I had to play a lot with categories. I was looking for an easy way to get category slug using an ID, and I found this great function that I’d like to share with you today.

First, put the following function in your functions.php file:

function get_cat_slug($cat_id) {
	$cat_id = (int) $cat_id;
	$category = &get_category($cat_id);
	return $category->slug;
}

Once done, you can call the function as shown below:

<?php echo get_cat_slug(3); ?>

The above code will display the slug for the category with the Category ID of 3.
