我在woocmmerce中获取下一个和上一个类别链接和名称时遇到问题。 实际上我找到了this,但它仅用于正常的wordpress类别帖子.. 我需要下一个和上一个产品类别...任何帮助..我会知道
我尝试了以下代码,但这根本不符合逻辑......:
global $wp_query;
// get the query object
$cat = $wp_query->get_queried_object();
$cateID = $cat->term_id -1;
$termname = get_term_by( 'id', $cateID, 'product_cat' );
$plinkname = get_term_link( $cateID, 'product_cat' );
这将重新启动+1类别ID ..但例如,当其中一个类别被删除时,它将无效。
答案 0 :(得分:0)
在 functions.php :
中{
"src": "Pictures/Comics/spi.jpg",
"descr": "Spider man is a nice comic The main spider-man comic ended with Peter Parker's death."
}
}
在主题文件中调用此函数:
function woocommerce_next_prev_link() {
if ( is_product_category() ){
$taxonomy = 'product_cat';
// Load all the terms for the product category
$terms = get_terms( array(
'taxonomy' => $taxonomy,
'hide_empty' => FALSE,
) );
// Put all of the category id's into a simple array for searching
$ids = array();
foreach( $terms as $term ) {
$ids[] = $term->term_id;
}
global $wp_query;
$cat_obj = $wp_query->get_queried_object();
// Load the current term ID from the current query
$this_term = $cat_obj->term_id;
// Find the term in the list of ID's
$this_position = array_search( $this_term, $ids );
// Identify the previous term
$prev_position = $this_position - 1;
// Identify the next term
$next_position = $this_position + 1;
// IF the previous term exists, and is not "off" the list (the currently displayed term is not the first term), then display the link
if( $prev_position >=0 ) {
$prev_id = array_slice( $ids, $prev_position, 1 );
$prev_term = get_term( $prev_id[0], $taxonomy );
if ( $prev_term ) {
echo '<a href="' . get_term_link( $prev_term->term_id, $taxonomy ) . '">« ' . $prev_term->name . '</a>';
}
}
// IF the next term exists, and is not "off" the list (the currently displayed term is not the last term), then display the link
if( $next_position > 0 && $next_position < count($ids) ) {
$next_id = array_slice( $ids, $next_position, 1 );
$next_term = get_term ($next_id[0], $taxonomy );
if ( $next_term ) {
echo '<a href="' . get_term_link( $next_term->term_id, $taxonomy ) . '">' . $next_term->name . ' »</a>';
}
}
}
