随机显示一些内容长度有限的 WooCommerce 产品评论

如何解决随机显示一些内容长度有限的 WooCommerce 产品评论

我正在为基于 WooCommerce: Display some reviews randomly on home page 的评论制作简码，以便放在其他页面上。如何按字符数限制评论，例如 100 或 200 个字符。所以它们不会太长并且适合任何页面。

我现在正在使用以下代码进行评论

function get_random_five_stars_products_reviews( $atts ) {
    // Extract shortcode attributes
    extract( shortcode_atts( array(
        'limit' => 5,// number of reviews to be displayed by default
    ),$atts,'woo_reviews' ) );

    $comments = get_comments( array(
        'status'      => 'approve','post_status' => 'publish','post_type'   => 'product','Meta_query'  => array( array(
            'key'     => 'rating','value'   => '5',) ),) );

    shuffle($comments);

    $comments = array_slice( $comments,$limit );

    $html = '<ul class="products-reviews">';
    foreach( $comments as $comment ) {
        $rating = intval( get_comment_Meta( $comment->comment_ID,'rating',true ) );
        $html .= '<li class="review">';
        $html .= '<div>'.get_the_title( $comment->comment_post_ID ).'</div>';
        if ( $rating > 4 ) $html .= wc_get_rating_html( $rating );
        $html .= '<div>' .$comment->comment_content.'</div>';
        $html .= "<div>Posted By :".$comment->comment_author." On ".$comment->comment_date. "</div>";
        $html .= '</li>';
    }
    return $html . '</ul>';
}
add_shortcode('woo_reviews','get_random_five_stars_products_reviews');

解决方法

要限制显示 5 个开头的评论，内容不超过特定长度（此处为 100 个字符），请使用以下内容：

function get_random_five_stars_products_reviews( $atts ) {
    // Extract shortcode attributes
    extract( shortcode_atts( array(
        'limit'      => 5,// number of reviews to be displayed by default
        'length'     => 100,// Limit comments text content lenght
        'show_stars' => true,// Or "false" to hide
    ),$atts,'woo_reviews' ) );

    $comments = get_comments( array(
        'status'      => 'approve','post_status' => 'publish','post_type'   => 'product','meta_query'  => array( array(
            'key'     => 'rating','value'   => '5',) ),) );

    shuffle($comments);

    $count = 0; // Initializing
    $html  = '<ul class="products-reviews">';
    
    foreach( $comments as $comment ) {
        $content = $comment->comment_content;
        if( strlen($content) <= $length && $count < $limit ) {
            $rating = intval( get_comment_meta( $comment->comment_ID,'rating',true ) );
            $html .= '<li class="review">';
            $html .= '<div>'.get_the_title( $comment->comment_post_ID ).'</div>';
            if ( $show_stars ) {
                $html .= wc_get_rating_html( $rating );
            }
            $html .= '<div>' .$content. '</div>';
            $html .= "<div>Posted By :".$comment->comment_author." On ".$comment->comment_date. "</div>";
            $html .= '</li>';
            $count++; // Increase count
        }

        if ( $count == $limit ) {
            break; // Stop the loop
        }
    }
    return $html . '</ul>';
}
add_shortcode('woo_reviews','get_random_five_stars_products_reviews');

代码位于活动子主题（或活动主题）的functions.php 文件中。它应该有效。
