wp_create_category() WordPress Function

The wp_create_category() function allows you to create a new category in WordPress. This function takes two arguments: the name of the category and the parent category. The name argument is required, while the parent category is optional. If you don't specify a parent category, the new category will be created as a top-level category.

wp_create_category( int|string $cat_name, int $category_parent ) #

function wp_create_category( $cat_name, $category_parent = 0 ) {
	$id = category_exists( $cat_name, $category_parent );
	if ( $id ) {
		return $id;
	}

	return wp_insert_category(
		array(
			'cat_name'        => $cat_name,
			'category_parent' => $category_parent,
		)
	);
}
