Hi all,

Using code provided by Ryan here, I've created a module that coverts a PageArray into JSON format.

It's been super useful to me, and I'm hoping it will be for others as well

Couple things I'm looking to do to improve this module are to:

• add the ability to pass in the native fields you'd like in the output
• add an option in the Field Details section for whether or not you want the field included in JSON output

Re the first one, I could use a bit of help trying to figure out how to pass options into a hooked function. I've tried adding an $options param to addHook, like this:

$this->addHook('PageArray::toJSON', $this, 'pagesToJSON', $options);

and calling it like this:

$myPages->toJSON(array('fields' => 'id,name'));

But, when I do I get this error:


Method PageArray::toJSON does not exist or is not callable in this context (in /Projects/TeamScheme/teamscheme_0.5/wire/core/Wire.php line 231)

If someone could point me in the right directions for adding params to hooked functions (and perhaps point to a module that implements something like I want to do wfor item #2) I would appreciate it.

Thanks.

Could be really helpful for creating a public read API for a PW page sometime.

This sounds great Evan, I can't wait to check this one out. To answer your question about how to pass arguments to a hook function:

$myPages->toJSON($a, $b, $c); 

public function toJSON(HookEvent $event) {
  $a = $event->arguments[0];
  $b = $event->arguments[1];
  $c = $event->arguments[2]; 
}

Since you want to pass in an options array as the first argument, you would call your function like in your example, and you could retrieve the argument like this:

$options = $event->arguments[0];
