validating inputfield settings from input tab

[owzim]

I have a Module, which is an InputField, I have some custom settings, which is accessible via the input tab on the field edit page. I want to validate the settings given by the user.

What I have so far (like suggested here):

$this->addHookAfter('InputField::processInput', $this, 'HookValidateSettingsInput');
public function HookValidateSettingsInput(HookEvent $event){
    
    $inputfield = $event->object;
    
    // unsafe because there can be other fields with that name on other templates
    // and this hook would trigger there as well
    if ($inputfield->name == "nameOfTheInputField") {
        // do stuff
    }
}

But this is totally unsafe.

How can I check if the currently processed inputfield (which is a text area in this case) belongs to the InputFiled settings of my module.

I can't find any reference within the $event->object, just a bunch of input field wrappers with numbers.

Thanks.

Horst to the rescue:

$event->arguments[0]->type; // spits out the actual Fieldtype class name
