$smarty VS $this->smarty

[qrczak]

Can someone explain me why according to many tutorials when I want to assign variable to hook I should do like this:

 

for example inside the public function hookHeader()

 

$this->smarty->assign(array(

    'myvariable' => 'mytext'

));

 

but it doesn't works for me BUT works for me when I make like this:

 

global $smarty;

$smarty->assign(array(

    'myvariable' => 'mytext'

));

 

Any ideas?

You should use 

$this->context->smarty
