get category ID from Slug

bypan6 had the right answer though…

$catid = get_cat_id(‘slug’);
echo $catid;

No, the get_cat_ID function gets a category by the name of the category, not by the slug.

I have just tried and it worked ;D

Only because you have the same slug as the category name is. If the slug had been different (like if you have a space in your category name, it’ll be a dash in the slug), then your code won’t work.

Pretty old topic but this might be useful:
get_category_by_slug(‘category-slug’)->term_id

I’m using it in:
<?php echo category_description(get_category_by_slug(‘category-slug’)->term_id); ?>
