WordPress Get Category ID from Slug
Quick WordPress snippet for getting the category ID from the category slug.
Don’t blink or you’ll miss it:
$slug = 'docs';
$cat = get_category_by_slug($slug);
$catID = $cat->term_id;Here we pass the $slug to WordPress’ get_category_by_slug() function. That gives us an object of useful category data, including the ID, which we then call directly:
$catID = $cat->term_id;
To see what else is available try adding the following to your script:
print_r($cat);
It’s just good times.
