Default value: ''

Return

(string) The path of the file.

Source

function get_theme_file_path( $file = '' ) {
	$file = ltrim( $file, '/' );

	if ( empty( $file ) ) {
		$path = get_stylesheet_directory();
	} elseif ( file_exists( get_stylesheet_directory() . '/' . $file ) ) {
		$path = get_stylesheet_directory() . '/' . $file;
	} else {
		$path = get_template_directory() . '/' . $file;
	}
