Hello,

I am trying to do what you indicate in a Prestashop 1.7.5 (@Rolige), I have created a new module, but it does not work, I am not very clear where to place this line in the php.

$this->context->smarty->assign('all_combinations', (new Product($id_product))->getAttributeCombinations());

This is my php file code for my module:

<?php
if(!defined('_PS_VERSION_'))
exit;

class extraInfo extends Module{
  
  public function __construct()
  {
      $this->name = 'extra_info';
      $this->tab = 'front_office_features';
      $this->version = '1.0.0';
      $this->author ='pShark';
      $this->need_instance = 0;
      $this->ps_versions_compliancy = array('min' => '1.7.x.x', 'max' => _PS_VERSION_);
      $this->bootstrap = true;

      parent::__construct();

      $this->displayName = $this->l('Product - Extra Information');
      $this->description = $this->l('Extra information in product page');
      $this->confirmUninstall = $this->l('Are you sure you want to uninstall the module?');

      $this->templateFile = 'module:extra_info/views/templates/hook/extra_info.tpl';
  }

  public function install()
  {
      return (parent::install()
      && $this->registerHook('displayHeader')
      && $this->registerHook('displayProductAdditionalInfo')
      );
  
      $this->emptyTemplatesCache();
  
      return (bool) $return;
  }

  public function hookDisplayHeader($params)
  {
    $this->context->smarty->assign('all_combinations', (new Product($id_product))->getAttributeCombinations());
    $this->context->controller->registerStylesheet('modules-extraInfo', 'modules/'.$this->name.'/views/css/extra_info.css', ['media' => 'all', 'priority' => 150]);
  }

  public function uninstall()
  {
    $this->_clearCache('*');

    if(!parent::uninstall() || !$this->unregisterHook('displayProductAdditionalInfo'))
      return false;

    return true;
  }

  public function hookDisplayProductAdditionalInfo()
  {
    return $this->display(__FILE__, 'views/templates/hook/extra_info.tpl');
  }

}

I have added the line to assign the smarty variable in hookDisplayHeader(), but I have tried to add it in hookDisplayProductAdditionalInfo() and __construct(), but it does not work.

Then in tpl file, I have placed the code that you indicated:

{foreach from=$all_combinations item=item}
  {$item.quantity}
{/foreach}

The module loads in the hook that I have indicated perfectly (I have tried to place a text in the tpl and it appears), but it does not load the information of the combinations, I imagine that the smarty variable is not assigned correctly.

Does anyone know why it doesn't work? do you see something wrong in my code?

Regards!
