根据类别显示随机产品

Question

我在产品的单个产品页面中。我想在该产品之后展示 4 个其他相同类别的随机产品

我所拥有的就是这个：（PHP）

<?php

        global $product;

        $terms = get_the_terms( $product->get_id(), 'product_cat' );

        var_dump($terms);

    $args = array(

        'posts_per_page'   => 4,

        'orderby'          => 'rand',

                'post_type'        => 'product' ); 

    $random_products = get_posts( $args );

    foreach ( $random_products as $post ) : setup_postdata( $post ); ?>

    <li>

        <a href="<?php the_permalink(); ?>">

    <?php the_title(); ?></a>

    </li>

<?php endforeach; 

wp_reset_postdata();

?>

谁能帮我？谢谢

你可以试试这个方法。我检查了它是否有效：global $product;&nbsp; &nbsp; $terms = get_the_terms( $product->get_id(), 'product_cat' );&nbsp; &nbsp; $first_term = array_shift( $terms );&nbsp; &nbsp; $args = array(&nbsp; &nbsp; &nbsp; &nbsp; 'posts_per_page'&nbsp; &nbsp;=> 4,&nbsp; &nbsp; &nbsp; &nbsp; 'orderby'&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; => 'rand',&nbsp; &nbsp; &nbsp; &nbsp; 'post_type'&nbsp; &nbsp; &nbsp; &nbsp; => 'product',&nbsp; &nbsp; &nbsp; &nbsp; 'tax_query' => array(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; array(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'taxonomy' => 'product_cat',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'field'&nbsp; &nbsp; => 'slug',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'terms'&nbsp; &nbsp; => array( $first_term->slug )&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; )&nbsp; &nbsp; &nbsp; &nbsp; ),&nbsp; &nbsp; &nbsp; &nbsp; 'post__not_in' => array( $product->get_id() )&nbsp; &nbsp; );&nbsp; &nbsp; $random_products = get_posts( $args );&nbsp; &nbsp; foreach ( $random_products as $post ) : setup_postdata( $post ); ?>&nbsp; &nbsp; &nbsp; &nbsp; <li>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href="<?php the_permalink(); ?>">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <?php the_title(); ?></a>&nbsp; &nbsp; &nbsp; &nbsp; </li>&nbsp; &nbsp; <?php endforeach;&nbsp; &nbsp; wp_reset_postdata();&nbsp; &nbsp; ?>
