我想自定義 WooCommerce 類別頁面 (archive-product.php) 以顯示當(dāng)前產(chǎn)品類別，但我也想在頁面中的某處創(chuàng)建指向上一個(gè)和下一個(gè)類別術(shù)語鏈接的上一個(gè)和下一個(gè)鏈接。我嘗試了很多解決方案但沒有運(yùn)氣。我已經(jīng)設(shè)法實(shí)現(xiàn)了一個(gè)采用實(shí)際類別 ID 的代碼，我添加了 +1 和 -1，并且能夠創(chuàng)建鏈接，但最大的問題是當(dāng)“下一個(gè)鏈接”位于最后一個(gè)不起作用的類別時(shí)，不是鏈接的無限循環(huán)。即，如果我在第 6 頁上，即我擁有的最后一個(gè)類別，下一個(gè)應(yīng)該是 1，上一個(gè)應(yīng)該是 5，如果我在第一個(gè)類別上，上一個(gè)應(yīng)該是 6，下一個(gè)應(yīng)該是 2。請(qǐng)?jiān)谙旅嬲业轿艺谑褂貌⑶艺诠ぷ鞯环衔倚枰拇a：<?php$taxonomy = 'product_cat';$cate = get_queried_object();$cateID = $cate->term_id;$next_cateID = $cateID + 1;$prev_cateID = $cateID - 1; $next_term_link = get_term_link( $next_cateID, $taxonomy );$next_term = get_term( $next_cateID, $taxonomy );$next_slug = $next_term->name;$prev_term_link = get_term_link( $prev_cateID, $taxonomy );$prev_term = get_term( $prev_cateID, $taxonomy );$prev_slug = $prev_term->name;?><p><a href="<?php echo $prev_term_link ?>"><?php echo $prev_slug; ?></a></p><p><a href="<?php echo $next_term_link ?>"><?php echo $next_slug; ?></a></p>

更新：
您只需定義第一個(gè)和最后一個(gè)類別 ID。然后它將作為無限循環(huán)工作（假設(shè)您的產(chǎn)品類別術(shù)語是連續(xù)的）：
<?php
if ( is_product_category() ) :
$taxonomy = 'product_cat'; // WooCommerce product category taxonomy
$term_id = get_queried_object_id(); // Current product category term Id
// Get first product category term Id
$query_args = array('taxonomy' => 'product_cat', 'hide_empty' => false, 'orderby' => 'term_id', 'number' => '1', 'fields' => 'ids');
$term_id_1st = get_terms($query_args);
$term_id_1st = reset($term_id_1st);
// Get last product category term Id
$query_args['order'] = 'DESC';
$term_id_end = get_terms($query_args);
$term_id_end = reset($term_id_end);
$next_term_id = $term_id_end == $term_id ? $term_id_1st : $term_id + 1;
$prev_term_id = $term_id_1st == $term_id ? $term_id_end : $term_id - 1;
$next_term_link = get_term_link( $next_term_id, $taxonomy );
$next_term = get_term( $next_term_id, $taxonomy );
$prev_term_link = get_term_link( $prev_term_id, $taxonomy );
$prev_term = get_term( $prev_term_id, $taxonomy );
?>
<p><a href="<?php echo $prev_term_link ?>"><?php echo $prev_term->name; ?></a></p>
<p><a href="<?php echo $next_term_link ?>"><?php echo $next_term->name; ?></a></p>
<?php endif; ?>
