Add "Show More" link in review on product detail page. Only want to show 5 reviews at a time.

Answer 1

You can achieve by overriding below file.

Step 1: In your module please create file di.xml under path PackageName/Vendor/etc/frontend

<?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="Magento\Review\Block\Product\View\ListView" type="PackageName\Vendor\Block\Rewrite\Product\View\ListView" />
</config>

Step 2: Please create file ListView.php file under path PackageName/Vendor/Block/Rewrite/Product/View/

<?php
namespace PackageName\Vendor\Block\Rewrite\Product\View;

class ListView extends \Magento\Review\Block\Product\View\ListView
{
    protected function _prepareLayout()
    {
        $toolbar = $this->getLayout()->getBlock('product_review_list.toolbar');
        if ($toolbar) {
            $toolbar->setAvailableLimit(array(2=>2,4=>4,6=>6))->setShowPerPage(true);
            $toolbar->setCollection($this->getReviewsCollection());
            $this->setChild('toolbar', $toolbar);
        }
        return $this;
    }
}

You can change setAvailableLimit(array(2=>2,4=>4,6=>6)) according to your need.
