这看起来很简单,但我不知道为什么下面的代码不起作用。我在谷歌上搜索了很多,有很多解决方案,但对我不起作用。伙计们,请让我知道我缺少了什么。
下面的我的代码:
<ul class="category-sidebar">
<?php
$get_parent_cats = array(
'parent' => '0' //get top level categories only
);
$all_categories = get_categories( $get_parent_cats );//get parent categories
foreach( $all_categories as $single_category ){
//for each category, get the ID
$catID = $single_category->cat_ID;
echo '<li><a href=" ' . get_category_link( $catID ) . ' ">' . $single_category->name . '</a>'; //category name & link
$get_children_cats = array(
'child_of' => $catID //get children of this parent using the catID variable from earlier
);
$categories = get_categories($args);
$child_cats = get_categories( $get_children_cats );//get children of parent category
echo '<ul class="children">';
foreach( $child_cats as $child_cat ){
//for each child category, get the ID
$childID = $child_cat->cat_ID;
//for each child category, give us the link and name
echo '<a href=" ' . get_category_link( $childID ) . ' ">' . $child_cat->name . '</a>';
}
echo '</ul></li>';
} //end of categories logic ?>
</ul><!--end of category-sidebar-->
这只是给我分类,而不是其中的子分类。请帮助任何人。
提前谢谢。
嘿,我找到了解决方案:
<ul class="category-sidebar">
<?php
$get_parent_cats = array(
'parent' => '0','hide_empty' => false //get top level categories only
);
$all_categories = get_categories( $get_parent_cats );//get parent categories
foreach( $all_categories as $single_category ){
//for each category, get the ID
$catID = $single_category->cat_ID;
echo '<li><a href=" ' . get_category_link( $catID ) . ' ">' . $single_category->name . '</a>'; //category name & link
$get_children_cats = array(
'child_of' => $catID,'hide_empty' => false //get children of this parent using the catID variable from earlier
);
$categories = get_categories($args);
$child_cats = get_categories( $get_children_cats );//get children of parent category
echo '<ul class="children">';
foreach( $child_cats as $child_cat ){
//for each child category, get the ID
$childID = $child_cat->cat_ID;
//for each child category, give us the link and name
echo '<a href=" ' . get_category_link( $childID ) . ' ">' . $child_cat->name . '</a>';
}
echo '</ul></li>';
} //end of categories logic ?>
</ul>
感谢大家抽出时间。:)
