Hi there,
How does one go about defining and implementing a JS hook in V.4?
Here is an example of the particular issue I am facing:
An old addon I am trying to upgrade contains the following snippet:
```php
```
and when I run it in v.4, firebug has this to say:
“ReferenceError: fn_register_hooks is not defined”
Has the function name changed?
How is js hooking done in v.4?
Any help with this would be awesomely appreciated, thanks!
