Hooks; the docs are misleading

[numediaweb]

The 1.6 docs says: 

In order to attach your code to a hook, you must create a non-static public method, starting with the "hook" keyword followed by either "display" or "action", and the name of the hook you want to use.

 

So why we have this hook:

$this->registerHook('displayFooterProduct')..

but then we the called back method named differently in our module:

public function hookProductFooter($params).. 

Isn't that supposed to follow the naming convention and be 

public function hookDisplayFooterProduct($params).. 

And why 'display' in the docs is lowercase and in the method is first letter uppercase 'Display'.

 

 

To finish, as I wanted to call a custom hook from a template, the doc says:

It is easy to call a hook from within a template file (.tpl): you simply have to use its name with the hook function. You can add the name of a module that you want the hook execute.

What do they mean by You can add the name of a module that you want the hook execute.?

 

Thanks!

It is actually be the class name of the module in lower case - which is also the directory name of the module (via the naming convention).
