Today I wrote some very small plugins for Smarty, which allow me to use CI’s URL helper functions (base_url() and site_url()) directly from my Smarty templates.
So I decided to share them:
function.site_url.php
<?php
function smarty_function_site_url($params,&$smarty)
{
//check if the needed function exists
//otherwise try to load it
if (!function_exists('site_url')) {
//return error message in case we can't get CI instance
if (!function_exists('get_instance')) return "Can't get CI instance";
$CI= &get_instance();
$CI->load->helper('url');
}
if (!isset($params['url'])) return base_url();
else return site_url($params['url']);
}
?>
function.base_url.php
<?php
function smarty_function_base_url($params,&$smarty) {
if (!function_exists('base_url')) {
//return error message in case we can't get CI instance
if (!function_exists('get_instance')) return "Can't get CI instance";
$CI= &get_instance();
$CI->load->helper('url');
}
return base_url();
}
?>
Installation: just drop these two files in smarty’s plugin folder.
Usage:
{base_url} to output the root url of your site (e.g. http://fest.servehttp.com/)
{site_url url=“controller/function”} produces something like this http://fest.servehttp.com/index.php/controller/function
Not the most advanced plugins ever, but some might find them useful.
