definition of hooks

[osit]

Hi, I have some problem with undarstanding prestashop structure.

index.tpl in theme’s directory by default contains only {$HOOK_HOME}
so where is this hook actually defined?

[razaro]

It is defined in index.php in root folder.

$smarty->assign('HOOK_HOME', Module::hookExec('home'));

Some links about hooks

ok, but i still cant find this code for HOME.
My question is where I can find html/php code for HOMEor elements of HOME. I saw where it's defined but no information what it contains and where to look for it. Can u help me with that?

In second link

home Homepage content

Allows you to add code to the center column on the homepage only.
It is called in index.php and then displayed in index.tpl.

And go to Back Office >> Modules >> Positions and under Homepage content you see list of modules that are "hooked" to HOME.

So any module that you want to be displayed on homepage must have this function in modules php code

    function hookHome($params)
   {

           // here is called modules tpl file like
           return $this->display(__FILE__, 'editorial.tpl');

        }
