access $config inside function

[pogidude]

Hi,

I'm trying to do the following inside a function:

function register_styles(){
   $url = $config->urls->templates.'styles/';

   /** for working with google fonts **/
   $fonts = array(
      'Source+Sans+Pro:300,400,700',
      'Dosis:400,700'
      );

   $styles = array(
       'google-fonts' => 'http://fonts.googleapis.com/css?family=' . implode('|', $fonts )
      ,'bootstrap' => $url.'bootstrap.css'
      ,'base' => $url.'base.css'
      ,'structure' => $url.'structure.css'
      ,'design' => $url.'design.css'

      );

   return $styles;
} 

but I'm getting an error on this

$config->urls->templates.'styles/'

"Call to a member function add() on a non-object"

thanks for helping

Due to scope, you need to use wire('config') inside a function. Same is true for all the PW variables:
http://processwire.com/api/variables/

If you'll be using it a lot in the function, you can do $config = wire('config') and then use $config as normal after that.

awesome!!

thanks! by the way, where do I find a reference for all "wire('config')" and "wire('pages')" thing? or this a convention? $page, $pages, $config equal to wire('var')?

$page, $pages, $config equal to wire('var')?

Yes, $page is same as wire('page') and so on
