I can create a Twig extension for my project like this
class Functions extends Twig_Extension{
public function getName(){return 'foobar';}
public function getFunctions() {
return array(
'loremipsum' => new \Twig_SimpleFunction('asset', 'Functions::loremipsum')
);
public static function loremipsum($foo) {
return $foo;
}
}
this works, but I want to use a constructor to inject some data that I need in some functions.
Simply using 'asset'
in Twig_SimpleFunction
will result in PHP trying to execute the functon loremipsum()
public function getFunctions() {
return array(
'foo' => new Twig_Function_Method($this, 'bar');
);
}
public function bar($baz) {
return $this->foo . $baz;
}
Look at all the different classes that extend Twig_Function
for all the different ways to specify template functions.
For the newer Twig_SimpleFunction
, it seems you can pass any kind of callable
as the second argument to the constructor:
new Twig_SimpleFunction('foo', array($this, 'bar'))
