从 WP_Query 中的当前产品类别术语 ID 获取所有 Woocommerce 产品

Question

我有一个简单的分类法-product_cat.php 页面，我试图在其中仅显示当前类别中的产品。现在，它显示所有产品，而不仅仅是当前类别中的产品。这是我的代码：

<ul class="products">

    <?php
       $current_cat_id = $wp_query->get_queried_object()->term_id;
       $args = array(
         'taxonomy'       => 'product_cat',
         'post_type'      => 'product',
         'post_status'    => 'publish',
         'posts_per_page' => -1,
         'tax_query'      => array(
             'taxonomy'   => 'product_cat',
             'field'      => 'term_id',
             'terms'      => $current_cat_id,
             'operator'   => 'IN'
         )
       );

       $products = new WP_Query( $args );

       while ( $products->have_posts() ) : $products->the_post();
           echo '<li><a href="'. get_permalink() .'"><div class="product__preview"><img src="' . get_the_post_thumbnail_url() . '"></div><span>' . get_the_title() . '</span></a></li>';
       endwhile;

       wp_reset_query();
       ?>
</ul>

我的客户一直在更改类别的 names/slugs，所以我需要通过类别 ID 获取产品。知道为什么这会生成所有产品，而不仅仅是当前类别中的产品吗？

The tax query need to have 2 arrays embedded in each other: 'tax_query' => array( array(

删除了第一个不需要的'taxonomy' => 'product_cat',

已将 'terms' => $current_cat_id, 替换为 'terms' => array( get_queried_object()->term_id ),

替换了wp_reset_query()；通过 wp_reset_postdata();

您的代码将是：

$query = new WP_Query( array(
    'post_type'      => 'product',
    'post_status'    => 'publish',
    'posts_per_page' => -1,
    'tax_query'      => array( array(
        'taxonomy'   => 'product_cat',
        'field'      => 'term_id',
        'terms'      => array( get_queried_object()->term_id ),
    ) )
) );

while ( $query->have_posts() ) : $query->the_post();
    echo '<li><a href="'. get_permalink() .'"><div class="product__preview"><img src="' . get_the_post_thumbnail_url() . '"></div><span>' . get_the_title() . '</span></a></li>';
endwhile;

wp_reset_postdata();

经过测试并有效

虽然它的正确答案你可以通过类别 slug 得到它。

    $args = array(
        'post_type'      => 'product',
        'posts_per_page' => 10,
        'product_cat'    => 'category slug here',
    );
    $products_all = new WP_Query( $args );

Answer 3

            $terms = wp_get_post_terms( $product->id, 'product_cat' );  
            $args_listing = array( 
            'post_type' => 'product',
            'tax_query'      => array( array(
            'taxonomy'   => 'product_cat',
            'field'      => 'term_id',
            'terms'      => $terms[0]->term_id,
            ) ),
            'orderby'=> 'date',
            'order'=> "desc",
            'posts_per_page' => 10,
            'paged' => $paged                   
            );


            I think you can try this. its working for me.
