WooCommerce：在主页上随机显示一些评论

Question

我希望每次有人访问时我的主页上都会出现 5 条随机评论。

我找到了一些代码来获取所有评论：

//add get product reviews to homepage

function get_woo_reviews()
{
    $count = 0;
    $html_r = "";
    $title="";
    $args = array(
        'post_type' => 'product'
    );

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

    foreach($comments as $comment) :
        $title = ''.get_the_title( $comment->comment_post_ID ).'';
        $html_r = $html_r. "" .$title."";
        $html_r = $html_r. "" .$comment->comment_content."";
        $html_r = $html_r."Posted By".$comment->comment_author." On ".$comment->comment_date. "";
    endforeach;

    return $html_r;
}

add_shortcode('woo_reviews', 'get_woo_reviews');

当我将短代码 [woo_reviews] 添加到此 test page 时，它工作得很好。

如何将其更改为仅获得 5 条随机评论？

此外，我现在如何设置此页面的格式以使其只有 5 条评论并能够更改页面上评论的外观（间距、字体等）？

Answer 1

添加以下代码片段-

function get_woo_reviews()
{
    $comments = get_comments(
        array(
            'status'      => 'approve',
            'post_status' => 'publish',
            'post_type'   => 'product',
        )
    ); 
    shuffle($comments);
    $comments = array_slice( $comments, 0, 5 );
    $html = '<ul>';
    foreach( $comments as $comment ) :
        $html .= '<li><h2>'.get_the_title( $comment->comment_post_ID ).'</h2>';
        $html .= '<p>' .$comment->comment_content.'</p>';
        $html .= "<p>Posted By :".$comment->comment_author." On ".$comment->comment_date. "</p></li>";
    endforeach;
    $html .= '</ul>';
    ob_start();
    echo $html;
        $html = ob_get_contents();
    ob_end_clean();

    return $html;
}
add_shortcode('woo_reviews', 'get_woo_reviews');

评论WP_Comment_Query，评论不能乱序。所以你需要使用简单的轻量级 SQL 查询，使用专用的 WordPressWPDB Class.

在下面的代码中，您可以更改样式和 html 结构以获得所需的输出。您还可以使用可用的简码参数 "limit" （默认设置为 5 来设置要以随机顺序显示的评论数量):

add_shortcode('woo_reviews', 'get_random_woo_reviews');

function get_random_woo_reviews( $atts ){
    // Shortcode Attributes
    $atts = shortcode_atts( array(
        'limit' => '5', // <== Set to 5 reviews by default
    ), $atts, 'woo_reviews' );

    global $wpdb;

    // The SQL random query on product reviews
    $comments = $wpdb->get_results( $wpdb->prepare("
        SELECT *
        FROM  {$wpdb->prefix}comments c
        INNER JOIN {$wpdb->prefix}posts p ON c.comment_post_ID = p.ID
        WHERE c.comment_type = 'review' AND p.post_status = 'publish'
        ORDER BY RAND() LIMIT %d
    ", intval( esc_attr($atts['limit']) ) ) );

    ob_start(); // Start buffering

    ## CSS applied styles
    ?>
    <style>
        ul.product-reviews, ul.product-reviews li { list-style: none; margin:0; padding:0; line-height: normal;}
        ul.product-reviews li { display:block; max-width: 200px, padding: 10px; display:inline-block; vertical-align: text-top;}
        ul.product-reviews li .title {font-size: 1.2em;}
        ul.product-reviews li .content {max-width: 180px; font-size: 0.9em; margin-bottom: 6px;}
        ul.product-reviews li .author, ul.product-reviews li .date  {display: block; font-size: 0.75em;}
    </style>
    <?php

    ## HTML structure
    ?>
    <ul class="product-reviews"><?php

    foreach ( $comments as $comment ) {
        ?>
        <li>
            <h4 class="title"><?php echo get_the_title( $comment->comment_post_ID ); ?></h4>
            <div class="content"><?php echo $comment->comment_content; ?></div>
            <span class="author"><?php printf( __("Posted By %s") . ' ', '<strong>' . $comment->comment_author . '</strong>' ); ?></span>
            <span class="date"><?php printf( __("On %s"), '<strong>' . date_i18n( 'l jS \of F Y', strtotime( $comment->comment_date) ) . '</strong>' ); ?></span>

        </li>
        <?php
    }
    ?></ul><?php

    return ob_get_clean(); // Return the buffered output
}

代码进入您的活动子主题（或活动主题）的 function.php 文件。已测试并有效。

用法： [woo_reviews] 或 php：echo do_shortcode( "[woo_reviews]" );
