Using static/object methods for hooks

[tsgeoff]

Hey all.

 

Is there a specified restriction on the kinds of functions that can be passed into the add_hook() function?

 

For example, I have a few hooks that I've grouped together on a single object. However, it seems as if WHMCS is not able to add hooks from object methods or static class methods.

 

I've tried adding hooks like this:

$hookObj = new SomeHookObject();
add_hook('HookName', 1, $hookObj->hookName());

 

And like this:

add_hook('HookName', 1, 'SomeHookObject::hookName');

 

But neither way has it working. Plain old functions work. I can only assume that WHMCS enforces functions only in some way?

 

Any help would be appreciated.
