我正在尝试获取子类别子类别的产品类别
<?php
$taxonomy = 'product_cat';
$orderby = 'name';
$show_count = 0; // 1 for yes, 0 for no
$pad_counts = 0; // 1 for yes, 0 for no
$hierarchical = 1; // 1 for yes, 0 for no
$title = '';
$empty = 0;
$args = array(
'taxonomy' => $taxonomy,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$all_categories = get_categories( $args );
foreach ($all_categories as $cat) {
if($cat->category_parent == 0) {
$category_id = $cat->term_id;
$args2 = array(
'taxonomy' => $taxonomy,
'child_of' => 0,
'parent' => $category_id,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$sub_cats = get_categories( $args2 );
if( $sub_cats ) {
echo '<li class="title '.$cat->name.'"><a >
';
echo $cat->name ;
echo '<i class="chevron right icon"></i>
</a></li>';
$sub_cats = "";
}else {
echo '<li class="titleVide '.$cat->name.'Hide"><a >
';
echo $cat->name ;
echo '</a></li>';
$sub_cats = "";
}
$args2 = array(
'taxonomy' => $taxonomy,
'child_of' => 0,
'parent' => $category_id,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$sub_cats = get_categories( $args2 );
if($sub_cats) {
echo '<li class="content"> <p>';
foreach($sub_cats as $sub_category) {
echo '
<a href="'. get_term_link($sub_category->slug, "product_cat" ) .'">'. $sub_category->name . '</a>
';
}
echo ' </p></li>';
} else {
echo '';
}
$sub_cats = "";
}
} /* end foreach all_categories cat */
wp_reset_query();
?>
此代码按层次列出了它们下面的所有顶级类别和子类别,但我有子类别(子子类别)的子类别,所以我如何列出这些子子类别(带有clic)。
答案 0 :(得分:0)
使用child_of =当前类别ID
尝试以下代码<?php
$taxonomy = 'product_cat';
$orderby = 'name';
$show_count = 0; // 1 for yes, 0 for no
$pad_counts = 0; // 1 for yes, 0 for no
$hierarchical = 1; // 1 for yes, 0 for no
$title = '';
$empty = 0;
$args = array(
'taxonomy' => $taxonomy,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$all_categories = get_categories( $args );
foreach ($all_categories as $cat) {
if($cat->category_parent == 0) {
$category_id = $cat->term_id;
$args2 = array(
'taxonomy' => $taxonomy,
'child_of' => 0,
'parent' => $category_id,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$sub_cats = get_categories( $args2 );
if( $sub_cats ) {
echo '<li class="title '.$cat->name.'"><a >
';
echo $cat->name ;
echo '<i class="chevron right icon"></i>
</a></li>';
$sub_cats = "";
}else {
echo '<li class="titleVide '.$cat->name.'Hide"><a >
';
echo $cat->name ;
echo '</a></li>';
$sub_cats = "";
}
$args2 = array(
'taxonomy' => $taxonomy,
'child_of' => $category_id,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$sub_cats = get_categories( $args2 );
if($sub_cats) {
echo '<li class="content"> <p>';
foreach($sub_cats as $sub_category) {
echo '
<a href="'. get_term_link($sub_category->slug, "product_cat" ) .'">'. $sub_category->name . '</a>
';
}
echo ' </p></li>';
} else {
echo '';
}
$sub_cats = "";
}
} /* end foreach all_categories cat */
wp_reset_query();
?>
或使用wp_list_categories()函数列出类别 https://developer.wordpress.org/reference/functions/wp_list_categories/
