Product list hook problem

[Moggen]

Hi

I have created module for displaying discount price based on third party api and I have created a custom hook in my module and in category.php. So far everything is good I can display test message any where I wont by moving my {hook} in the product-list template. Now my problem is that the hook i called once when category.php smarty assign is called but is there a way for my module to know witch product is displayed in the loop. Because I cant figure out how to calculate each product price based on the list witch is give by $params and some how assign correct price to the module template.

Thanks for any help

I'm interested in this, too as I will be writing a module to get real-time stock status and need to understand the hooks for something like this.

Can you explain how you created your custom hook?

[Moggen]

Well the hook its self is realy easy

I have in my install function something like this:

simplefied not comleat

function install() {

if(!parren::install())
{
return false;
}

$db = Db::getInstance()
$db->Execute("insert into ps_hook name title description position values myHook, title, desc, 1 ");
if(!Hook:registerHook("myHook"){
return false
}

return true
}

This will do 3 inserts first add my module in parrent::install (this must be done first to get id to hook register). Then I do a simple insert of my hook to ps_hook table. Last I execute registerHook this function will add myHook to module_hook and like the hook to this module.


the I just create myHook function something like this

function myHook($params) {
}


Then I add the Hook execute function in the assign to smart in category.php

I'm not understanding this.

Ok I think what I am trying to do is not possible with a hook but I will try to explain my code a bit more

My module

monthlycost

class MonthlyCost extends Module {

   function __construct()
   {
       $this->name = 'monthlycost';
       $this->tab = 'Payment';
       $this->version = '0.1';
       parent::__construct();

       $this->displayName = $this->l('Monthly Cost');
       $this->description = $this->l('Display monthly cost for part payment');
       $this->confirmUninstall = $this->l('Are you sure you want to delete your module ?');
   }

   function install()
   {
       if (!parent::install()) {
           return false;
       }
       $db = Db::getInstance();
       $db->Execute( "INSERT INTO `ps_hook` (`name`, `title`, `description`) VALUES ('monthlyCost', 'Part payment', 'Part payment')" );
       if (!$this->registerHook('monthlyCost')) {
           return false;
       }
       return true;
   }

   function uninstall() {

       $idHook = Hook::get( 'monthlyCost' ) ;

       $db = Db::getInstance();
       $db->Execute(" DELETE FROM " . _DB_PREFIX_ . "hook WHERE id_hook = " . $idHook );
       $this->unregisterHook( $idHook );

       if( !parent::uninstall() ) {
           return false;
       } else {
           return true;
       }
   }

   public function hookMonthlyCost( $params ) {
               api calculations on price
              return $this->display(__FILE__, 'monthlycost.tpl');
        }
}

and in category.php
row 64 I have added following row:
'HOOK_PART_PAYMENT' => Module::hookExec('monthlyCost',array("products" => $cat_products)),


And in product-list.tpl
{$HOOK_PART_PAYMENT}

But the thing is that when i Exec monthlyCost i will return a html rendered by the template in the module.
Then when the product-list.tpl loops $HOOK_PART_PAYMENTit will off course display the same price over and over again.
So basically what I need is a way to execute the hook foreach row in the template and supply a id like.
{EXEC_HOOK v=$product.id} or something like that.
