lanstrip.snippet.php

<?php
/**
 * lanstrip snippet to output different languages, e.g. in Gallery templates.
 * The snippet displays the text matching the current "cultureKey".
 * Can be used anywhere - in chunks, templates etc.
 * The default text must be written first, without a preceeding "#" - this text is used if no matching cultureKey is found.
 * To make the Gallery snippet display a text in different languages, the editor enters the album title like this:
 * "Blå båt #en Blue boat #de Blau Boot"
 * In the gallery item chunk the snippet is called like this:
 * [[lanstrip? &text=`[[+name]]`]]
 *
 * @version 1.0
 * @author Roger Käll (kallteknik.se)
 *
 * @example [[lanstrip? &text=`Svenska #en Engelska #de Tyska`]] or when using a property [[lanstrip? &text=`[[+name]]`]]
 *
