Would it be possible to add functions to Twig within the theme PHP file (IE: antimatter.php)?
Yes! In the class named after the theme inside a method onTwigExtensions
, you can add something like:
// ...
public function onTwigExtensions()
{
$function = new \Twig_SimpleFunction ('mytest', function () {
return "This is a test.";
});
$this->grav['twig']->twig->addFunction($function);
}
// ...
And use it in Twig with {{ mytest() }}
.
