Magento2. Homepage Hot sellers

Question

I want to get the all products and make changes in these product showing on the homepage

Answer 1

This products are shown as widget in home-page-block cms block.

It is Catalog Product list widget, so you can configure Number of Products to Display, template, and wich products to show.

Answer 2

You can do an override like this :

app/code/YourNamespace/YourModule/etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\CatalogWidget\Block\Product\ProductsList">
        <plugin name="module_widget_override" type="YourNamespace\YourModule\Plugin\Block\Product\MyOverridePlugin" />
    </type>
</config>

app/code/YourNamespace/YourModule/Plugin/Block/Product/MyOverridePlugin.php

<?php

namespace YourNamespace\YourModule\Plugin\Block\Product;


class MyOverridePlugin
{
    die('IT WORKS')
}

If you want to modify the template , open the template path hints LINK . And override the template that is displaying thoses products.

I think this is the template:

vendor/magento/module-catalog-widget/view/frontend/templates/product/widget/content/grid.phtml

Make the logic in this section

<?php if ($showWishlist || $showCompare || $showCart): ?>
                                    <div class="product-item-actions">
                                        <?php if ($showCart): ?>
                                            <div class="actions-primary">
                                                <?php if ($_item->isSaleable()): ?>
                                                    <?php if ($_item->getTypeInstance()->hasRequiredOptions($_item)): ?>
                                                        <button class="action tocart primary" data-mage-init='{"redirectUrl":{"url":"<?= $block->escapeUrl($block->getAddToCartUrl($_item)) ?>"}}' type="button" title="<?= $block->escapeHtmlAttr(__('Add to Cart')) ?>">
                                                            <span><?= $block->escapeHtml(__('Add to Cart')) ?></span>
                                                        </button>
                                                    <?php else: ?>
                                                        <?php
                                                            $postDataHelper = $this->helper('Magento\Framework\Data\Helper\PostHelper');
                                                            $postData = $postDataHelper->getPostData($block->getAddToCartUrl($_item), ['product' => $_item->getEntityId()])
                                                        ?>
                                                        <button class="action tocart primary" data-post='<?= /* @noEscape */ $postData ?>' type="button" title="<?= $block->escapeHtmlAttr(__('Add to Cart')) ?>">

                                                        </button>
                                                    <?php endif; ?>
                                                <?php else: ?>
                                                    <?php if ($_item->getIsSalable()): ?>
                                                        <div class="stock available"><span><?= $block->escapeHtml(__('In stock')) ?></span></div>
                                                    <?php else: ?>
                                                        <div class="stock unavailable"><span><?= $block->escapeHtml(__('Out of stock')) ?></span></div>
