Question

我想显示按属性过滤的相关产品，该属性应等于页面cookie中的值。

我编辑related.php模板，如下所示：

<?php woocommerce_product_loop_start(); ?>

<?php foreach ( $related_products as $related_product ) :
    // extract attribute filter_location in an array
    $results = $related_product->get_attribute( 'pa_filter_location' );

    // extract value from cookies filter_location
    $fl = $_COOKIE['filter_location'];

    foreach ( $results as $key ) {
        if( $key == $fl ) {
            $post_object = get_post( $related_product->get_id() );

            setup_postdata( $GLOBALS['post'] =& $post_object );

            wc_get_template_part( 'content', 'product' );
        }
    }

endforeach; ?>

<?php woocommerce_product_loop_end(); ?>

但是我得到了错误：警告：

为foreach（）提供的参数无效

可能是什么问题？

问题来自此行：

$results = $related_product->get_attribute( 'pa_filter_location' );

这不是给出数组，而是用逗号分隔的术语字符串。因此，您不能以这种方式在foreach循环中使用它。

请使用以下重新访问的代码：

<?php woocommerce_product_loop_start(); ?>

<?php foreach ( $related_products as $related_product ) :
    // extract attribute filter_location in an array
    $terms = $related_product->get_attribute( 'pa_filter_location' );

    // Set each term in an array
    $terms = ! empty($terms) ? (array) explode(', ', $terms) : array();

    foreach ( $terms as $term ) {
        if( isset($_COOKIE['filter_location']) && $term == $_COOKIE['filter_location'] ) {
            $post_object = get_post( $related_product->get_id() );

            setup_postdata( $GLOBALS['post'] =& $post_object );

            wc_get_template_part( 'content', 'product' );
        }
    }

endforeach; ?>

<?php woocommerce_product_loop_end(); ?>

它应该彻底解决与foreach循环有关的错误。
