我正在使用以下内容wp_list_categories 类别页面上的代码。如果当前页面是父类别，则显示该类别的所有子类别；如果当前页面是子类别，则显示除当前类别外的父类别的所有子类别。
<?php if (is_category( )) {
$cat = get_query_var(\'cat\');
$thiscat = get_category ($cat);
$parent = $thiscat->parent;
$catname = get_cat_name( $cat );
if ($parent != \'\') {
echo \'<h2 class="widget-title"><span>Related Products</span></h2>\';
echo \'<ul>\';
wp_list_categories( array(
\'title_li\' => \'\',
\'child_of\' => $parent,
\'exclude\' => $cat,
\'use_desc_for_title\' => 0
) );
echo \'</ul>\';
}
else {
echo \'<h2 class="widget-title"><span>\' . $catname . \' Products</span></h2>\';
echo \'<ul>\';
wp_list_categories( array(
\'title_li\' => \'\',
\'child_of\' => $cat,
\'use_desc_for_title\' => 0
) );
echo \'</ul>\';
}
} ?>
然而，我现在意识到我需要将列出的每个类别包装在
<h3> 标题元素。我认为做这件事的唯一方法是使用
get_categories 然后使用
foreach 环

我现在使用以下代码，可以根据需要格式化列表：
<?php if (is_category( )) {
$thiscat = get_category( get_query_var( \'cat\' ) );
$catid = $thiscat->cat_ID;
$parent = $thiscat->category_parent;
if (!empty ($parent) ) {
//child category pages
$catlist = get_categories(
array(
\'child_of\' => $parent,
\'orderby\' => \'id\',
\'order\' => \'DESC\',
\'exclude\' => $catid,
\'hide_empty\' => \'0\'
) );
//widget title
echo \'<h2 class="widget-title"><span>Related Products</span></h2>\';
//categories list
foreach ( $catlist as $category ) {
echo \'<ul>\';
echo \'<li><h3 class="entry-title"><a href="\' . get_category_link( $category->cat_ID ) . \'" rel="bookmark">\' . $category->cat_name . \'</a></h3></li>\';
echo \'</ul>\';
}
}
else {
//parent category pages
$catname = get_cat_name( $catid );
$catlist = get_categories(
array(
\'child_of\' => $catid,
\'orderby\' => \'id\',
\'order\' => \'DESC\',
\'hide_empty\' => \'0\'
) );
//widget title
echo \'<h2 class="widget-title"><span>\' . $catname . \' Products</span></h2>\';
foreach ( $catlist as $category ) {
echo \'<ul>\';
echo \'<li><h3 class="entry-title"><a href="\' . get_category_link( $category->cat_ID ) . \'" rel="bookmark">\' . $category->cat_name . \'</a></h3></li>\';
echo \'</ul>\';
}
}
} ?>
