  1. Woocommerce made a reviews out of regular wordpress comments.

    The simple way is to get a comments of ‘post_type’ => ‘product’, that will get raw comment data. In order to display proper woocommerce review out of that you need to apply a callback function witch is ‘callback’ => ‘woocommerce_comments’.

    The whole thing is:

    <?php
    $args = array ('post_type' => 'product');
    $comments = get_comments( $args );
    wp_list_comments( array( 'callback' => 'woocommerce_comments' ), $comments);
?>

    If you want to get the comment by product ID then you need to change that $args: 

    $args = array ('post_id' => 123);

    To customize it more check out that references:

    http://codex.wordpress.org/Function_Reference/wp_list_comments
    http://codex.wordpress.org/get_comments

    The ‘callback’ => ‘woocommerce_comments’ function uses a template located in plugins/woocomerce/templates/single-product/review.php

  3. <div id="reviews">
<div id="comments">
    <h2><?php
        if ( get_option( 'woocommerce_enable_review_rating' ) === 'yes' && ( $count = $product->get_rating_count() ) )
            printf( _n( '%s review for %s', '%s reviews for %s', $count, 'woocommerce' ), $count, get_the_title() );
        else
            _e( 'Reviews', 'woocommerce' );
    ?></h2>

    <?php if ( have_comments() ) : ?>

        <ol class="commentlist">
            <?php wp_list_comments( apply_filters( 'woocommerce_product_review_list_args', array( 'callback' => 'woocommerce_comments' ) ) ); ?>
        </ol>

        <?php if ( get_comment_pages_count() > 1 && get_option( 'page_comments' ) ) :
            echo '<nav class="woocommerce-pagination">';
            paginate_comments_links( apply_filters( 'woocommerce_comment_pagination_args', array(
                'prev_text' => '&larr;',
                'next_text' => '&rarr;',
                'type'      => 'list',
            ) ) );
            echo '</nav>';
        endif; ?>

  4. Yes Sir, I’ve tried my level best to displays the reviews at the bottom of its default tabs, but I can’t do it for many days and finally I find your method to display the particular Product’s reviews. It working great. Awesome Sir Awesome.

    But one thing more to display the product’s reviews dynamically on single-product.php
    // Get the Id of product dynamically and print them (reviews) by ids.

    global $product;
$id = $product->id;

echo $id.",";
$args = array ('post_type' => 'product', 'post_id' => $id);
$comments = get_comments( $args );
wp_list_comments( array( 'callback' => 'woocommerce_comments' ), $comments);

    Just Paste this code in your single-product.php file see the result. It will show as you want.

  5. I have been recently having the same struggle and I came up with this solution that allows you to output reviews from all products on a single page.

    //Display all product reviews
if (!function_exists('display_all_reviews')) {
function display_all_reviews(){
    $args = array(
       'status' => 'approve',
       'type' => 'review'
    );

    // The Query
    $comments_query = new WP_Comment_Query;
    $comments = $comments_query->query( $args );

    // Comment Loop
    if ( $comments ) {
        echo "<ol>";
        foreach ( $comments as $comment ): ?>
        <?php if ( $comment->comment_approved == '0' ) : ?>
            <p class="meta waiting-approval-info">
                <em><?php _e( 'Thanks, your review is awaiting approval', 'woocommerce' ); ?></em>
            </p>
            <?php endif;  ?>
            <li itemprop="reviews" itemscope itemtype="http://schema.org/Review" <?php comment_class(); ?> id="li-review-<?php echo $comment->comment_ID; ?>">
                <div id="review-<?php echo $comment->comment_ID; ?>" class="review_container">
                    <div class="review-avatar">
                        <?php echo get_avatar( $comment->comment_author_email, $size = '50' ); ?>
                    </div>
                    <div class="review-author">
                        <div class="review-author-name" itemprop="author"><?php echo $comment->comment_author; ?></div>
                        <div class='star-rating-container'>
                            <div itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating" class="star-rating" title="<?php echo esc_attr( get_comment_meta( $comment->comment_ID, 'rating', true ) ); ?>">
                                <span style="width:<?php echo get_comment_meta( $comment->comment_ID, 'rating', true )*22; ?>px"><span itemprop="ratingValue"><?php echo get_comment_meta( $comment->comment_ID, 'rating', true ); ?></span> <?php _e('out of 5', 'woocommerce'); ?></span>

                                    <?php
                                        $timestamp = strtotime( $comment->comment_date ); //Changing comment time to timestamp
                                        $date = date('F d, Y', $timestamp);
                                    ?>
                            </div>
                            <em class="review-date">
                                <time itemprop="datePublished" datetime="<?php echo $comment->comment_date; ?>"><?php echo $date; ?></time>
                            </em>
                        </div>
                    </div>
                    <div class="clear"></div>
                    <div class="review-text">
                        <div itemprop="description" class="description">
                            <?php echo $comment->comment_content; ?>
                        </div>
                        <div class="clear"></div>
                    </div>
                <div class="clear"></div>           
            </div>
        </li>

        <?php 
        endforeach;
        echo "</ol>";
    } else {
        echo "This product hasn't been rated yet.";
    }
}
}

    Add the above function to your functions.php file.
    After this you can use this function on your theme wherever you would like by calling it like this:

    <?php echo display_all_reviews(); ?>

    I also created a tutorial here https://www.majas-lapu-izstrade.lv/get-woocommerce-customer-reviews-from-all-products-display-average-and-all-ratings-in-a-histogram-without-a-plugin/ that also includes functions to output average product rating, total count of all ratings from all products and all product review histogram.

  6. In woocommerce/templates/single-product/tabs/tabs.php

    If you run a print_r() on $tabs after it has been declared you’ll see that a portion of the output is the following:

    [reviews] => Array (
    [title] => Reviews (3)
    [priority] => 30
    [callback] => comments_template
)

    This means that the callback is the function: comments_template().

    Since this function doesn’t accept a $post_id parameter, the would need to be called within the loop.

    However, the function does accept a parameter of the template file to use, so to answer the OP’s direct question of how to use a custom template file – you can use the function like so: 

    comments_template( string $file = '/comments.php', bool $separate_comments = false );

    This ^ was taken directly from the codex

  8. I tried a lot to get any built-in function for this but i didn’t. Then i wrote my own query. It might help you:

    $comment_and_reviews = $wpdb->get_results("SELECT wpc.comment_author,wpc.comment_author_email,wpc.comment_date,wpc.comment_content,wpcm.meta_value AS rating FROM `" . $wpdb->prefix . "comments` AS wpc INNER JOIN  `" . $wpdb->prefix . "commentmeta` AS wpcm ON wpcm.comment_id = wpc.comment_id AND wpcm.meta_key = 'rating' WHERE wpc.comment_post_id = '" . $p_id . "' ");

  9. I take a week to find and had found a easy way to do it.

    If you want bring review product to a page just using WP_Query and put
    echo comments_template() inside

    or if you want a custom template review you can using template from wp-content/plugins/woocommerce/templates/single-product-reviews.php and put inside WP_Query

    Example in my case, I want bring review from product id 33051 to home page

    <?php   
    $args = array('post_type' => 'product','id' => 33051);
    $result = new WP_Query( $args );
    if ( $result-> have_posts() ) : ?>
    <?php while ( $result->have_posts() ) : $result->the_post(); ?>
    <?php comments_template(); // you can custom template by code in single-product-reviews.php
?>
<?php endwhile; ?>
<?php endif; wp_reset_postdata(); ?>
