我想知道如何限制wordpress woocommerce类别的显示。我只想显示前3个类别,但是此代码显示了所有类别。我不想显示水球类别
`<?php
$taxonomy = 'product_cat';
$orderby = '';
$show_count = 0;
$pad_counts = 0;
$hierarchical = 1;
$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;
$thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
?>`
我只想在首页上显示3个类别(随机选择其中任何一个)
答案 0 :(得分:4)
您需要添加数字参数以限制类别。
'number' => 3,
