How to create a hook?

[SWcoins.com]

Hello,

 

I was wondering if anybody knew how to create a hook?

 

I know how to write a module using the existing hooks but what I want to do is write a module that hooks under the product long description. If one exists I am over looking it, if not, how would you go about writing a module with a customized hook? The online docs don't explain how to create a hook. 

 

Thanks,

You need to create a record in ps_hook table and then place the following code to the existing PS file (depends on what do you want to hook):

 

Hook::exec('yourHookName', array(
	'example_parameter1' => $example_value1,
	'example_parameter2' => $example_value2,
));

By using the second arguments you can pass arguments to the hook.

In PS 1.5 is very easy , simply put in the smarty template {hook h='yourNewHook'}

 

 

and in the module register $this->registerHook('yourNewHook') and of course implement hookYourNewHook()
