Question

我无法排除相关产品Woocommerce中的当前产品，现在我已将相关产品从类别更改为子类别（无子项）。因此，相关产品将仅显示子类别产品（相同子类别），但现在它还将显示当前产品。任何人都有解决方案＆gt;谢谢

  if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

global $product, $woocommerce_loop;

if ( empty( $product ) || ! $product->exists() ) {
    return;
}

if ( ! $related = $product->get_related( $posts_per_page ) ) {
    return;
}

$cats_array = array(0);

// get categories
$terms = wp_get_post_terms( $product->id, 'product_cat' );

// select only the category which doesn't have any children
foreach ( $terms as $term ) {
    $children = get_term_children( $term->term_id, 'product_cat' );
    if ( !sizeof( $children ) )
    $cats_array[] = $term->term_id;
}



$args = apply_filters( 'woocommerce_related_products_args', array(
    'exclude' => array( $cur_product_id ),
    'post_type' => 'product',
    'ignore_sticky_posts' => 1,
    'post__not_in' => array( $cur_product_id ),
    'no_found_rows' => 1,
    'posts_per_page' => $posts_per_page,
    'orderby' => $orderby,
    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'field' => 'id',
            'terms' => $cats_array
        ),
    )
));

$products                    = new WP_Query( $args );
$woocommerce_loop['name']    = 'related';
$woocommerce_loop['columns'] = apply_filters( 'woocommerce_related_products_columns', $columns );

if ( $products->have_posts() ) : ?>

    <div class="related products">

        <h2><?php _e( 'Related Products', 'woocommerce' ); ?></h2>

        <?php woocommerce_product_loop_start(); ?>

            <?php while ( $products->have_posts() ) : $products->the_post(); ?>

                <?php wc_get_template_part( 'content', 'product' ); ?>

            <?php endwhile; // end of the loop. ?>

        <?php woocommerce_product_loop_end(); ?>

    </div>

<?php endif;

wp_reset_postdata();

Answer 1

你的问题是$ cur_product_id变量！改变：

$product->get_the_id()

Answer 2

非常感谢你。我找到了解决方案

添加此

$ terms = wp_get_post_terms（$ product-＆gt; id，'product_cat'）;

这个'post__not_in'=＆gt;数组（$ cur_product_id），

这是代码

 if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

global $product, $woocommerce_loop;

if ( empty( $product ) || ! $product->exists() ) {
    return;
}

if ( ! $related = $product->get_related( $posts_per_page ) ) {
    return;
}

$cats_array = array(0);
// The current product id (Woocommerce version retro compatible)
$cur_product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id; 
// get categories
$terms = wp_get_post_terms( $product->id, 'product_cat' );

// select only the category which doesn't have any children
foreach ( $terms as $term ) {
    $children = get_term_children( $term->term_id, 'product_cat' );
    if ( !sizeof( $children ) )
    $cats_array[] = $term->term_id;
}

$args = apply_filters( 'woocommerce_related_products_args', array(
    'exclude' => array( $cur_product_id ),
    'post_type' => 'product',
    'ignore_sticky_posts' => 1,
    'post__not_in' => array( $cur_product_id ),
    'no_found_rows' => 1,
    'posts_per_page' => $posts_per_page,
    'orderby' => $orderby,
    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'field' => 'id',
            'terms' => $cats_array
        ),
    )
));

$products                    = new WP_Query( $args );
$woocommerce_loop['name']    = 'related';
$woocommerce_loop['columns'] = apply_filters( 'woocommerce_related_products_columns', $columns );

if ( $products->have_posts() ) : ?>

    <div class="related products">

        <h2><?php _e( 'Related Products', 'woocommerce' ); ?></h2>

        <?php woocommerce_product_loop_start(); ?>

            <?php while ( $products->have_posts() ) : $products->the_post(); ?>

                <?php wc_get_template_part( 'content', 'product' ); ?>

            <?php endwhile; // end of the loop. ?>

        <?php woocommerce_product_loop_end(); ?>

    </div>

<?php endif;

wp_reset_postdata();

Woocommerce相关产品不包括子类别
