custom scripts

[helmut2509]

I want to implement some custom functions which are not related to the processwire core.

Do I have to store the respective scripts in the module folder?

What do I have to do to have access to the session variables in custom scripts?

What sort of custom functions are you talking about?

I want to implement some custom functions which are not related to the processwire core.

Do I have to store the respective scripts in the module folder?

No, in the module folder only modules should be.

You can store them outside of PW:

webroot
  |-customscripts
  |-site
  |-wire

and you can include them with include_once() or require_once() in the site/config.php if you like. This way your functions are available in PW where ever you need them.

What do I have to do to have access to the session variables in custom scripts?

You can access all of PWs API variables and methods in your custom functions through the wire() function:

$pagearray = wire('pages')->find('mySuperDuperSelectorValue');

$homepage = wire('pages')->get(1);
$homepage = wire('pages')->get('/');

$session = wire('session');
if( ! isset($session->myCustomArray['myCustomKey']) ) {
    $session->redirect('/');
}
