Custom product variable does not exists in product listing pages

[sanctusmob]

I have create a new variable ($show_discount) overriding product class.

Product.php class override

<?php 
Class Product extends ProductCore
{
    public $show_discount = 1;
    public function __construct($id_product = null, $full = false, $id_lang = null, $id_shop = null, Context $context = null)
    {
        self::$definition['fields']['show_discount'] = array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'size' => 1);
        parent::__construct($id_product, $full, $id_lang, $id_shop, $context);
    }
}
?>

and i am changing the value from the controller (override).

The variable exists in product page (var dump), but does not exists in product listing (category, new product, search  etc.)

Can anyone help?

Hi,

You need to access the variable on tpl for display it in the product page.
you can modify tpl files in root\themes\your_theme\templates\catalog directory for modifying display products

In product page the variable $show_discount exists and working properly.  I have edit the tpl and i have access to the variable from the product page.

But not from product listing pages (category, search, new products etc.). When i var dump $product in listing pages the variable $show_discount does not exists.

did you check to modify root\themes\your_theme\templates\catalog\_partials\miniatures\product.tpl ?

Yes.

in this case, you need to contact the theme developer and ask them about the issue, you have faced.

There is nothing to do with the theme. 

Has as say when I var dump $product in listing products the $product.show_discount does not exists. In product page the $product.show_discount exists and working as normal. 

I think my problem is in some controller. Maybe is stripping unnecessary variables for the listing products.

My guess is that in product listing does not assign all the variables from product class to smarty.

The project i was using that is obsolete for me...

I know this is an old thread.  But in case if anyone's looking for answer for the 'smarty not carrying the assigned variables' problem, here are my fixes.

Override

/controllers/front/listing/CategoryController.php

Then you can attach your variables in the 'initContent()' function.

<?php
class CategoryController extends CategoryControllerCore
{
    public function initContent()
    {
        parent::initContent();

        if ($this->category->checkAccess($this->context->customer->id)) {
            $this->doProductSearch(
                'catalog/listing/category',
                [
                    'entity' => 'category',
                    'id' => $this->category->id,
                ]
            );
        }
        $this->context->smarty->assign([
            'custom_variable' => 'some custom values...',
        ]);
    }
}
