Smarty template selection.

[Hajduk]

Ok, I am learning to handle smarty slowly but fail to see how I should use this code? If anyone can point me in the right direction I would apreciate it.

<?php

/**

* Smarty plugin

* @package Smarty

* @subpackage plugins

*/

/**

* Smarty {list_templates} plugin

*

* Type: function<br>

* Name: list_templates<br>

* Purpose: Prints the dropdowns for templates selection.

*

* ChangeLog:<br>

* Removed some useless assgned vars.

* Changed to get the selected template from $template assigned from the template, not from $_GET!

* Removed associative array keeping path=>name, names are == to paths when setting $smarty->template_dir

* @version 0.0.4

* @author Anton Blajev

* @param string

* @param Smarty

* @return string

function smarty_function_list_templates($params, &$smarty)
{

require_once $smarty->_get_plugin_filepath('function','html_options');

/* Default values. */

foreach ($params as $_key=>$_value) {

switch ($_key) {

case 'selected_template':

case 'sort':

case 'template':

$$_key = (string)$_value;

break;

default:

$smarty->trigger_error("[list_templates] unknown parameter $_key", E_USER_WARNING);

}

The Smarty WIKI plugins page offers the following description:

Purpose: List all available templates(from $smarty->templates_dir="somedir" and adds JS so you can switch between templates degining template=$TEMPLATE.

which I take to mean that it is a supporting utility that helps to manage different templates during development. I have been using Smarty on numerous sites for some time without ever needing it! Maybe someone will explain how this could transform our productivity in an instant....?

Well, I just started with it and am transferring things from normal CSS & PHP to Smarty. I run a site in 2 languages and hope this would ease it somehow. But I might as well just keep it all in 1 template with different files.

Sounds like you are working along the right lines.

For multi-language support, you could look at using configs to pre-load the required set of language text strings into a single template with config_load. This might be easier to maintain, as you would have a single template to maintain and not have to manage two keeping them in step.
