[solved] Can I pass a variable to a hook function?

[Robin S]

Is it possible to define a variable in the place that the hook is attached (e.g. ready.php or a template file) and then access that variable inside the hook function?

$animal = 'cat';
$this->addHookAfter('Class::method', function($event) {
    // is there some way to use $animal here?
});

I tried passing the variable as a second argument in the anonymous function but got an error.

Missing argument 2 for ProcessWire\ProcessWire::{closure}()

You can use $this->animal

$this->animal = 'cat';
$this->addHookAfter('Page::render', function($event) {
    bd($this->animal);
});

or you can also do this:

$animal = 'cat';
$this->addHookAfter('Page::render', function($event) use($animal) {
    bd($animal);
});

$animal = 'cat';
$this->addHookAfter('Class::method', function($event) use($animal) {
 // is there some way to use $animal here? Yes....use 'use'
 echo $animal;
 });

Edit...OK, so I am too slow....

Thanks @adrian, I knew there would be a simple solution.

And, thanks @kongondo
