helpers function

[eluser]royduin[/eluser]
With

Code:

$this->load->helper("url");

You load the url helper in system/helpers/url_helper.php
If loaded you have access to those functions, see: http://ellislab.com/codeigniter/user-gui...elper.html

If you need these functions on only one page you call

Code:

$this->load->helper("url");

If you're using the url helper on multiple pages it's recommended to autoload this by adding "url" to the autoloader array:

Code:

$autoload['helper'] = array("url");
