php - 在自定义 WooCommerce 报告中获取产品评论平均评级

Question

在 Woocommerce 中，我尝试显示每个产品的报告(HTML 表)，如下所示:

基于"Display total customers reviews and ratings average in WooCommerce "答案代码，以这种方式获取产品平均评分:

echo products_rating_average_html();

如何才能单独获得每个产品的平均评分...例如，如果产品有 4 或 5 条评论，则它会获得它们的平均评分(对于每个产品)

我还想获得每个产品的评论评论，以便将它们也放入表格中......

看看this answer thread ，您将在其中看到可以使用 WC_Product 方法，例如:

• get_average_ rating()
• get_ rating_counts()...

这是一个完整的示例:

1)获取产品所需相关数据(可定制):

$products_data = []; // Initializing

$products = wc_get_products( ['limit' => -1] ); // Get all WC_Product objects

// Loop through products -- Preparing data to be displayed
foreach ( $products as $product ) {
    $product_id = $product->get_id();

    // 1. Product data as product name …
    $products_data[$product_id]['name'] = $product->get_name();


    // 2. Average rating and rating count
    $products_data[$product_id]['rating'] = (float) $product->get_average_rating();
    $products_data[$product_id]['count']  = (int) $product->get_rating_count();

    // 3. Reviews -- Loop though product reviews
    foreach( get_approved_comments( $product_id ) as $review ) {
        if( $review->comment_type === 'review' ) {
            $products_data[$product_id]['reviews'][] = (object) [
                'author'    => $review->comment_author,
                'email'     => $review->comment_author_email,
                'date'      => strtotime($review->comment_date),
                'content'   => $review->comment_content,
            ];
        }
    }
}

2)可定制的表格显示:

echo '<table class="products-reviews-ratings"><tr>
    <th>'.__("ID").'</th>
    <th>'.__("Name").'</th>
    <th>'.__("Rating").'</th>
    <th>'.__("count").'</th>
    <th style="text-align:center">'.__("Reviews (author, date and content)").'</th>
</tr>';

foreach ($products_data as $product_id => $data){
    echo '<tr>
        <td>'.$product_id.'</td>
        <td>'.$data['name'].'</td>
        <td>'.$data['rating'].'</td>
        <td>'.$data['count'].'</td>
        <td style="text-align:center">';

    if( isset($data['reviews']) && $data['reviews'] > 0 ) {
        echo '<table>';

        // Loop through reviews
        foreach ($data['reviews'] as $review ){
            echo '<tr>
                <td><a href="mailto:'.$review->email.'">'.$review->author.'</a></td>
                <td>'.date( 'Y-m-d', $review->date ).'</td>
                <td>'.$review->content.'</td>
            </tr>';
        }
        echo '</table>';
    } else {
        _e('No reviews yet');
    }

    echo '</td></tr>';
}
echo '</table>';

你会得到类似的东西:
