I'm doing override widget to my custom module.

So everything was great in the backend, until i come to the frontend and see nothing at all.

I mean it works perfect in backend, but not with the frontend.

I'm following CatalogWidget.

So here is my custom module, check it out:

Its under namespace Gssi.

use MagentoFrameworkDataObjectIdentityInterface;

use MagentoWidgetBlockBlockInterface;

use MagentoCatalogWidgetBlockProductProductsList as CatalogWidgetProductList;



/**

class ProductsList extends CatalogWidgetProductList implements BlockInterface, IdentityInterface

{

    /**

    const DEFAULT_PRODUCTS_COUNT = 10;



    /**

    const PAGE_VAR_NAME = 'np';



    /**

    const DEFAULT_PRODUCTS_PER_PAGE = 5;



    /**

    const DEFAULT_SHOW_PAGER = false;

     * @param array $data

     */

    public function __construct(

        MagentoCatalogBlockProductContext $context,

        MagentoCatalogModelResourceModelProductCollectionFactory $productCollectionFactory,

        MagentoCatalogModelProductVisibility $catalogProductVisibility,

        MagentoFrameworkAppHttpContext $httpContext,

        MagentoRuleModelConditionSqlBuilder $sqlBuilder,

        MagentoCatalogWidgetModelRule $rule,

        MagentoWidgetHelperConditions $conditionsHelper,

        array $data = 

    ) {

        parent::__construct(

            $context,

            $productCollectionFactory,

            $catalogProductVisibility,

            $httpContext,

            $sqlBuilder,

            $rule,

            $conditionsHelper

        );

    }



    protected function _construct()

    {

        parent::_construct();

    }



}

As i said, i'm following CatalogWidget module, so this block ProductsList.php is extends from it ( I'm not sure if i need to call every function in that ProductList.php and use parent::_FunctionName or they just called themselves.).

The diffrence between my widget custom module and the widget of Catalog Widget module is i put 1 more <option> in the <parameter name="template">.

C:xampphtdocsbezdanappcodeGssiProductsSlideretcdi.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <preference for="MagentoCatalogWidgetBlockProductProductsList" type="GssiProductsSliderBlockProductProductsList" />

</config>

In here, slider.phtml and grid.phtml is the same, and also, i copy it from C:xampphtdocsbezdanvendormagentomodule-catalog-widgetviewfrontendtemplatesproductwidgetcontentgrid.phtml

So i will not post grid.phtml here.

    </div>

<?php endif;?>

The important thing is it seem like not running into the slider.phtml, because i've put echo "dsadsdsdsadsdsa" in the code, but it doesn't show up. So i dont know how to fix this.

Remove etcdi.xml as you do not need the preference and change your reference to the new template to include the new module's name.

app/code/Gssi/ProductsSlider/etc/widget.xml:39

<option name="slider" value="Gssi_ProductsSlider::product/widget/content/slider.phtml">
