function wp_insert_category( $catarr, $wp_error = false ) {
	$cat_defaults = array(
		'cat_ID'               => 0,
		'taxonomy'             => 'category',
		'cat_name'             => '',
		'category_description' => '',
		'category_nicename'    => '',
		'category_parent'      => '',
	);
	$catarr       = wp_parse_args( $catarr, $cat_defaults );

	if ( '' === trim( $catarr['cat_name'] ) ) {
		if ( ! $wp_error ) {
			return 0;
		} else {
			return new WP_Error( 'cat_name', __( 'You did not enter a category name.' ) );
		}
	}

	$catarr['cat_ID'] = (int) $catarr['cat_ID'];

	// Are we updating or creating?
	$update = ! empty( $catarr['cat_ID'] );

	$name        = $catarr['cat_name'];
