I am writting my custom helper. I tried to use the language helper:
$this->lang->line('site_title')
I get an error :
Fatal error: Using $this when not in object context in
C:\Users\guest\Wamp\www\codeIgniter\application\helpers\blog_helper.php on line 15
If you want to call methods from the CodeIgniter super object within a helper (or a custom library) you'll need to use the get_instance()
function. This will reference the CodeIgniter super object to the variable $ci - so you can call the CodeIgniter methods by using $ci
rather than $this
:
$ci =& get_instance();
$site_title = $ci->lang->line('site_title');
Or you can also use the language helper:
$site_title = lang('site_title');

That is assuming the helper before this point. Otherwise just do as above.
