Controller using hook

[timmyraynor]

I am trying to read through Developer Guide for PrestaShop 1.5, in the hand book it gives an example of using hook in the controller:

 

$this->context->smarty->assign('HOOK_LEFT_COLUMN', Module::hookExec('displayLeftColumn'));

 

but in what scenario we need to use the hook in the controller is not well explained, could anyone explain a example for me?

 

e.g. when using hook for modules, we could actually add page components.

then when using hook for controllers.....

 

Thanks

Hi,

Not sure I understood your question.

In the example, you're assigning the hook's content to the hook_left_column variable. WHen you place the variable somewhere in the template, all hooks hooked there will be displayed.

 

If you only need to execute the hook (say, to perform an action)m you simply call hookExec

That's my question too, this code is copied from the Prestashop 1.5 Developer Guide, I just want to know what is the purpose for doing such hookexec

I think that timmyraynor want to create a function on his controller that can be hooked by one of the existing prestashop hooks.

 

Like we can do on modules, simply create a function "actionValidateOrder()", but  now on controllers instead a module.

Anyone succeed to do such a thing?
