If more than one file name is - * specified, it will return location of file that it finds first. + * This function traverses the style tree (selected style and + * its parents in order, if inheritance is being used) and finds + * the first file on the filesystem matching specified relative path, + * or the first of the specified paths if more than one path is given. + * + * This function can be used to determine filesystem path of any + * file under any style, with the consequence being that complete + * relative to the style directory path must be provided as an argument. + * + * In particular, this function can be used to locate templates + * and javascript files. + * + * For locating templates get_first_template_location should be used + * as it prepends the configured template path to the template basename. + * + * Note: "selected style" is whatever style the style resource locator + * is configured for. + * + * The return value then will be a path, relative to the current + * directory or absolute, to the first existing file in the selected + * style or its closest parent. + * + * If the selected style does not have the file being searched, + * (and if inheritance is involved, none of the parents have it either), + * false will be returned. + * + * Multiple files can be specified, in which case the first file in + * the list that can be found on the filesystem is returned. + * + * If multiple files are specified and inheritance is involved, + * first each of the specified files is checked in the selected style, + * then each of the specified files is checked in the immediate parent, + * etc. + * + * Specifying true for $return_default will cause the function to + * return the first path which was checked for existence in the event + * that the template file was not found, instead of false. + * This is always a path in the selected style itself, not any of its + * parents. + * + * If $return_full_path is false, then instead of returning a usable + * path (when the file is found) the file's path relative to the style + * directory will be returned. This is the same path as was given to + * the function as a parameter. This can be used to check which of the + * files specified in $files exists. Naturally this requires passing + * more than one file in $files. * * @param array $files List of files to locate. * @param bool $return_default Determines what to return if file does not |
