FormAPI

So i had a question how to use FormAPI and i must download FormAPI's plugin ? On my plugin directory ?

 

If you want to use plugins that pop up a UI then just download formapi.phar and move to plugins folder

 

Okay It's good but i made this :

PHP:

$api = $this->plugin->getServer()->getPluginManager()->getPlugin("FormAPI");

And It's send to me "unexpected $this"

 

Remove $this

 

If i delete $this it's send to me unexpected "->"

 

Remove $this->
