how to set a cookie in product controller

[jahyax]

Good day,

 

the following is my code in product controller:

 

if (isset($this->product->unity) && $this->product->unity)

{

 

$this->context->cookie->__set($uty_opt, 'w_prc'); 

}

 

and in product.tpl , I am trying to display the cookie if it is already set my code is

 

<input type="text" value="{$uty_opt}" />

 

cookie value doesn't seems to appear

 

 

''''''''''My Goal'''''''

$this->context->cookie->your_tag = __set($uty_opt, 'w_prc');

then pass your_tag in smarty array from product controller

$this->smarty->assign('your_tag', $this->context->cookie->your_tag);

in your .tpl file you can access the variable with

$your_tag

note: creating a one off hack is one thing.

 

Make sure that you investigate hook  processing, i.e. rather than 'hack' core find a hook that will allow you  to insert your code. 

 

I realize hooks are not always in the place you need them.  But let's say you have a 'great' hack, if you accomplish without changing base code, you will end up with a 'portable' module that won't get 'lost' when you upgrade (productcontroller)...heck best case scenario is you can list it on addon's and make some money.

El Patron,

Fatal error: Call to undefined function __set() in ..../controllers\front\ProductController.php

El Patron, 

 

i did try your code suggestion I get this instead on product.tpl

 

Fatal error: Call to undefined function __set() in ..../controllers\front\ProductController.php

the function __set was used in your original example, I assumed you had that function already coded...if not then you  will need to build that function....

sorry, __set, was something I researched in the internet, when I try to use it, i had no error, I was assuming it is a valid prestashop method in setting up a cookie..

 

sorry for the confusion

 

What I really want to achieve is to Make a custom or additional cookie for the front page(product.tpl) that will hold a  value.

$this->context->cookie->your_tag = 'some value'

then pass your_tag in smarty array from product controller

$this->smarty->assign('your_tag', $this->context->cookie->your_tag);

in your .tpl file you can access the variable with

$your_tag

 

revised without the function call

El Patron, this is current what i have on my codes..

 

 

 

ProductController:

 

if (isset($this->product->unity) && $this->product->unity)

{

 

$this->context->cookie->your_tag = 'some value'

$this->smarty->assign('your_tag', $this->context->cookie->your_tag);

 

}

 

and on product.tpl

 

{$your_tag}

 

and I am getting 'Fatal error: Call to a member function assign() on a non-object in controllers\front\ProductController.php'

 

 

Am I missing something?

Try with:

$this->context->smarty->assign('your_tag', $this->context->cookie->your_tag);
