Introduction

Imagine you're navigating through your favorite online store, reading product reviews to decide whether or not to buy a certain item. Now, what if you discovered that the reviews don't show the star ratings? That would make your decision much harder. Ensuring that product reviews correctly display their ratings is crucial for any eCommerce platform, and Magento 2 is no exception. This blog post aims to guide you through the process of retrieving and displaying ratings for each review in Magento 2 programmatically. Whether you're a developer or a store owner looking to optimize your Magento store, this guide will provide you with the necessary insights and practical steps.

Why Review Ratings are Important in Magento 2

Review ratings play a vital role in shaping customer perceptions and can significantly impact purchasing decisions. The absence of ratings can lead to incomplete information, thus harming overall user experience. Magento 2 provides robust features for managing reviews, but displaying these ratings programmatically might sometimes pose a challenge. This guide aims to address these challenges and offer solutions.

The Challenge: Fetching Ratings Programmatically

Developers often find it straightforward to retrieve review texts and creation dates using the getDetail() method in Magento 2. However, the ratings, which offer visual insights into the quality of the product, often return zero or do not display as expected. This issue can be frustrating, especially when you’re sure that the ratings are stored in the database.

Understanding the Underlying Mechanism

Magento 2 uses a complex architecture for managing reviews and ratings. The ratings are stored separately and linked to the reviews through several layers of database tables. Understanding this structure is crucial for successfully retrieving the rating scores.

Key Components

  1. Review Repository: Handles retrieving the review data.
  2. Rating Factory: Manages the creation and manipulation of rating data.
  3. Magento Rating Model: Interacts with the rating data in the database.

Step-by-Step Guide to Fetch Ratings

Step 1: Set Up Your Environment

Before diving into the code, ensure that your development environment is set up correctly. You’ll need access to your Magento 2 installation and a good text editor or IDE.

Step 2: Retrieve the Review Data

First, fetch the review data programmatically. This involves querying the review repository to get the necessary review details.

use Magento\Review\Model\ReviewFactory;

protected $_reviewFactory;

public function __construct(
    \Magento\Review\Model\ReviewFactory $reviewFactory
) {
    $this->_reviewFactory = $reviewFactory;
}

// Load the review
$review = $this->_reviewFactory->create()->load($reviewId);

Step 3: Load the Ratings

The key operation is to load the ratings associated with the reviews. To do this, you will use the getRatingVotes() method from the review model.

use Magento\Review\Model\ResourceModel\Review\SummaryFactory;

protected $_reviewSummaryFactory;

public function __construct(
    \Magento\Review\Model\ResourceModel\Review\SummaryFactory $reviewSummaryFactory,
    \Magento\Review\Model\ReviewFactory $reviewFactory
) {
    $this->_reviewSummaryFactory = $reviewSummaryFactory;
    $this->_reviewFactory = $reviewFactory;
}

// Load ratings
$votes = $review->getRatingVotes();
foreach ($votes as $vote) {
    echo $vote->getPercent();
    echo $vote->getRatingCode();
}

Step 4: Troubleshooting Common Issues

Ratings Returning Zero

If the getRatingVotes() method returns zero, it's crucial to verify that the ratings are correctly saved and associated with the reviews. Ensure that you have the correct review ID and that the ratings data exists in the database.

Database Integrity

Check the database tables to ensure the integrity of the ratings data. Ratings and reviews are linked through several tables including rating_vote, review, and rating_option_vote. Any mismatch or corruption in these tables might result in incorrect data being fetched.

Step 5: Displaying the Ratings

Once you successfully retrieve the ratings, the next step is to display them appropriately on the frontend. This could mean updating your templates and scripts to ensure the ratings are shown alongside the reviews.

foreach ($votes as $vote) {
    echo '<div class="review-rating">';
    echo '<span class="rating-code">'. $vote->getRatingCode() .': </span>';
    echo '<span class="rating-percent">'. $vote->getPercent() .' %</span>';
    echo '</div>';
}

Conclusion

Fetching and displaying ratings for reviews in Magento 2 can be intricate but entirely doable by following a methodical approach. By understanding the underlying architecture and using the right methods, you can ensure that your product reviews are fully informative and beneficial to potential customers. The steps outlined in this blog post provide a comprehensive guide to achieving this goal.
