More Information More Information

Parameters:

  • $cat_name: Name for the new category.
  • $parent: Category ID of the parent category.

Returns:

  • 0 on failure, category id on success.

wp_create_category() is a thin wrapper around wp_insert_category().

Because this is a wrapper, it is not suitable for entering a complex custom taxonomy element.

If the category already exists, it is not duplicated. The ID of the original existing category is returned without error.
