效果如下：

• 1.主题functions下添加：

function display_product_container($title, $describe, $coverImg,$downloadHtml) {
    // 生成1到10之间的随机整数
    $random_m = rand(1, 10);
    
    echo '<div class="product-container" style="opacity: 0;">
        <div class="product-box relative" >
            <div class="product-background absolute"  style="
            height: 100%;
            width: 100%;
            background-image: url(' . $coverImg . ');
            z-index: -1;
            content: &quot;&quot;;
            top: 0;
            left: 0;
            right: 0;
            bottom: 0;
            filter: blur(20px);
            position: absolute;
            "></div>

                <div class="payrow-6 payrow-right">

        </div>
    </div>';
}
add_action('qk_product_container', 'display_product_container', 10, 4);

• 然后找到qkua\qkua\Modules\Templates\Single.php

搜索get_breadcrumbs()

替换这个function为：

        $post_id = get_the_id();
