Question

我有3个产品类别 - CATEGORY-1，CATEGORY-2和CATEGOTRY-3

我还创建了3个额外的自定义分类，用作每个类别的TAGS，分别是TAGS-1，TAGS-2和TAGS-3。

我编辑了Woocommerce单品并创建了自定义标签。在此选项卡中，我想根据类别选择显示我的自定义标签。

因此，如果为产品选择了CATEGORY-1，那么我想显示TAGS-1，如果选择了CATEGORY-2，那么我想显示TAGS-2和最后一组相同。

我的代码目前看起来像这样：

<?php global $post, $product, $woocommerce;

    if ( has_term( 'CATEGORY-1', 'product_cat' ) ) {

        $tags = wp_get_object_terms( $post->ID, 'TAGS-1' );

    } elseif ( has_term( 'CATEGORY-2', 'product_cat' ) ) {

        $tags = wp_get_object_terms( $post->ID, 'TAGS-2' );

    } elseif ( has_term( 'CATEGORY-3', 'product_cat' ) ) {

        $tags = wp_get_object_terms( $post->ID, 'TAGS-3' );     

    }

    return $tags;


    if ( $tags ) : ?>

        <ul id="TAGS-LIST">

            <?php foreach ( $tags as $tag ) : ?>

                <li>

                   <?php $tag_link = esc_url( get_term_link( $tag ) ); ?>

                        <a href="<?php echo $tag_link; ?>" class="TAG-CLASS">
                           <span class="TAG-TEXT-CLASS"><?php echo $tag->name; ?></span>
                        </a>
                    </li>

                <?php endforeach; ?>

            </ul><!-- #TAG-LIST -->

    <?php endif; ?>

但不幸的是，我似乎无法使其发挥作用。根本没有输出显示。我哪里错了？

Answer 1

在不知道产品数据的情况下，很难确切地说出原因。我会在那里放一些echo语句来试图找出意外发生的事情。例如

<?php global $post, $product, $woocommerce;

if ( has_term( 'CATEGORY-1', 'product_cat' ) ) {

    $tags = wp_get_object_terms( $post->ID, 'TAGS-1' );

} elseif ( has_term( 'CATEGORY-2', 'product_cat' ) ) {

    $tags = wp_get_object_terms( $post->ID, 'TAGS-2' );

} elseif ( has_term( 'CATEGORY-3', 'product_cat' ) ) {

    $tags = wp_get_object_terms( $post->ID, 'TAGS-3' );     

}
echo 'cat = ' . wp_get_object_terms( $post->ID,  'product_cat' );
echo 'tags1 = ' . wp_get_object_terms( $post->ID,  'TAGS-1' );
echo 'tags2 = ' . wp_get_object_terms( $post->ID,  'TAGS-2' );
echo 'tags3 = ' . wp_get_object_terms( $post->ID,  'TAGS-3' );

return $tags;


if ( $tags ) { ?>

    <ul id="TAGS-LIST">

        <?php foreach ( $tags as $tag ) : ?>

            <li>

               <?php $tag_link = esc_url( get_term_link( $tag ) ); ?>

                    <a href="<?php echo $tag_link; ?>" class="TAG-CLASS">
                       <span class="TAG-TEXT-CLASS"><?php echo $tag->name; ?></span>
                    </a>
                </li>

            <?php endforeach; ?>

        </ul><!-- #TAG-LIST -->

<?php } else { echo 'no tags present'; }  ?>

这有帮助吗？

好的，所以我走了很长的路，虽然现在工作正常，有没有办法让整个事情变得更短？
