create new functionality in prestashop

[cactus20]

Hi guys, I create a module in prestashop to show in home page.

 

My product in prestashop have categories (chocolate, cheese, candy...) and tags (usa, uk, china, spain...), my module show a list of all tags and a second list with categories.

When I click in a tag I have to show all  product with this tags.... for example if I click un "usa" I have to show

 

chocolate ---- 3items

Cheese ---- 2 items

Candy ---- 4 items

 

and all this product are from usa tags

 

By other hands when I click in categories for example "cheese"

I have to create a list with

 

Usa cheese--- 2 items

Uk cheese --- 4 items

Spain cheese --- 5 items

 

 

What is the best way to do that?

 

Create other module to do this functionality and show this in product-list.tpl.

 

What is the best way to do that?

 

Thanks in advance.

Hi guys, I think that I have the solution, I am override the ProductController to add new function and call a new view too, but my question is, how create a hyperlink to this new function?

Hi, tupe of hyperlink? to product page or category page?

It depends on what action you want to execute.

 Hi ndiaga for you reply, I override my controller I have a new function call getTagsProducts but I don't know create a link in my view to call this function using getProductLink

[cactus20]

 

From a module you create a link this way:

'my_link' => $this->context->link->getModuleLink('module_name', 'controller_name'),

// in  smarty array

Sorry ndiaga, I don't understand very well you solution... I explain better..

 

I have a module create by myself, this module call to homeparadise.tpl view with some parameters like this 

  $this->context->smarty->assign(array(
    'products' => $products,
    'categories' => $allCategories,
    'tag_element' => $country_tag
    ));
                
  return $this->display(__FILE__, 'homeparadise.tpl');

So now I homeparadise.tpl I show the info like that

 

  {foreach from=$v item=value}
            {* {$product|print_r}; *}
            <a href="{$link->getProductLink({$product.id_product})}">
            'my_link' => $this->context->link->getModuleLink('module_name', 'controller_name'),


              <img src="{$img_dir}img_paradise/{$tag_element[$value]}.jpg" class="img-responsive" alt="UP3 company"/>
              <div class="country_name">{$tag_element[$value]|escape:html:'UTF-8'}</div>
             
             </a>
             
            {/foreach}  

I need to change this

<a href="{$link->getProductLink({$product.id_product})}">

to call a new function that I create in Product controller

 

How to do that in PrestaShop?

 

Thanks in advances!

Ok so here is what you need:

{foreach from=$v item=value}
            {* {$product|print_r}; *}
            <a href="index.php?id_product={$product.id_product}&controller=product&id_lang={Tools::getValue('id_lang')}">
			
              <img src="{$img_dir}img_paradise/{$tag_element[$value]}.jpg" class="img-responsive" alt="UP3 company"/>
              <div class="country_name">{$tag_element[$value]|escape:html:'UTF-8'}</div>
             
             </a>
             
   {/foreach}  

//you don't need to create a link fot that.

this is not necessary 

my_link' => $this->context->link->getModuleLink('module_name', 'controller_name'),

 Thanks  Ndiaga I see, but where you call a function that it is in the Product controller 

 

  public function getByTag($tag_name){
....
    }
