The code snippet below demonstrates how to display the average rating and total number of reviews for a WooCommerce product:
/**
* Display average rating and total reviews for a product.
*
* @param int $product_id The ID of the product.
*/
function wpsnippets_display_product_reviews( $product_id ) {
$average_rating = wc_get_average_rating( $product_id );
$review_count = get_comments_number( $product_id );
echo '<div class="product-reviews">';
echo '<p>Average Rating: ' . $average_rating . '</p>';
echo '<p>Total Reviews: ' . $review_count . '</p>';
echo '</div>';
}
To use this code snippet, you can call the wpsnippets_display_product_reviews() function and pass the product ID as a parameter. It will then retrieve the average rating and total number of reviews for that product using WooCommerce functions (wc_get_average_rating() and get_comments_number()), and display them within a <div> element.
This code snippet can be useful when you want to show the average rating and total number of reviews for a product on its single product page or in a product listing. It provides valuable information to potential customers and helps them make informed purchasing decisions.
Examples
Example 1: Displaying Average Rating on Product Page
This use case demonstrates how to display the average rating for a WooCommerce product on the product page.
/**
* Display average rating on product page.
*/
function wpsnippets_display_average_rating() {
global $product;
if ( $product->get_average_rating() ) {
echo '<div class="average-rating">' . $product->get_average_rating() . '</div>';
}
}
add_action( 'woocommerce_single_product_summary', 'wpsnippets_display_average_rating', 10 );
This code example uses the woocommerce_single_product_summary action hook to add a custom function that displays the average rating of the current product. The get_average_rating() method is used to retrieve the average rating value, and it is then echoed within a <div> element.
Example 2: Adding Custom Rating Field to Checkout
This use case demonstrates how to add a custom rating field to the WooCommerce checkout page.
/**
* Add custom rating field to checkout.
*/
function wpsnippets_add_custom_rating_field( $checkout ) {
echo '<div id="custom_rating_field">';
woocommerce_form_field( 'custom_rating', array(
'type' => 'select',
'class' => array( 'form-row-wide' ),
'label' => __( 'Rating', 'woocommerce' ),
'required' => true,
'options' => array(
'' => __( 'Select a rating', 'woocommerce' ),
'1' => __( '1 star', 'woocommerce' ),
'2' => __( '2 stars', 'woocommerce' ),
'3' => __( '3 stars', 'woocommerce' ),
'4' => __( '4 stars', 'woocommerce' ),
'5' => __( '5 stars', 'woocommerce' ),
)
), $checkout->get_value( 'custom_rating' ) );
echo '</div>';
}
add_action( 'woocommerce_after_order_notes', 'wpsnippets_add_custom_rating_field' );
This code example uses the woocommerce_after_order_notes action hook to add a custom function that displays a select field for the rating on the checkout page. The woocommerce_form_field() function is used to generate the HTML for the field, with options for different rating values.
Example 3: Customizing Review Submission Form
This use case demonstrates how to customize the review submission form in WooCommerce.
/**
* Customize review submission form.
*/
function wpsnippets_customize_review_form( $fields ) {
$fields['comment_field']['label'] = __( 'Your Review', 'woocommerce' );
$fields['comment_field']['placeholder'] = __( 'Write your review here...', 'woocommerce' );
$fields['comment_field']['rows'] = 5;
$fields['rating']['required'] = false;
return $fields;
}
add_filter( 'woocommerce_product_review_comment_form_args', 'wpsnippets_customize_review_form' );
This code example uses the woocommerce_product_review_comment_form_args filter to modify the arguments for the review submission form. The function wpsnippets_customize_review_form() customizes the label, placeholder, and number of rows for the review comment field. It also sets the rating field as not required by setting the required parameter to false.
