[wordpress]B2主题美化 子专题设置

我发现一个问题, 专题分类设置子专题 但是跟没设置完全一样, 于是改了下源码,

现在如果父专题有子专题, 父专题只显会示子专题类目了

只要在子主题模板里 创建 Pages/collection.php 然后粘贴即可

<?php

use B2\Modules\Templates\Collection;
use B2\Modules\Common\Post;

/**
 * 专题聚合页面
 */
get_header();

$paged = get_query_var('paged');
$paged = $paged ? $paged : 1;

$data = Collection::get_collection_list(array('paged' => $paged));

$_pages = $data['pages'];

$data = $data['data'];

$img = b2_get_option('template_collection', 'collection_image');

$name = b2_get_option('template_collection', 'collection_title');

$desc = b2_get_option('template_collection', 'collection_desc');

$order = b2_get_option('template_collection', 'collection_post_order');
$order = !empty($order) ? $order : 'asc';

?>
<?php if (b2_get_option('template_collection', 'collection_open_cover')) { ?>
    <div class="collection-top mg-b" style="background-image:url(<?php echo $img; ?>)">
        <h1><?php echo $name; ?></h1>
        <p><?php echo $desc; ?></p>
    </div>
<?php } else { ?>
    <div class="pianli">
        <h1><?php echo $name; ?></h1>
        <p><?php echo $desc; ?></p>
    </div>
<?php } ?>
<div id="primary-home" class="wrapper">
    <main class="site-main">
        <div class="collection-box <?php echo empty($data) ? 'box' : ''; ?>">
            <?php
            if (!empty($data)) {
                foreach ($data as $k => $v) {
                    $post_data = $v['posts']['data'];
                    $q = get_term_meta($v['id'], 'b2_tax_index', true);

                    // 检查子类
                    global $wpdb;
                    $query = "SELECT * FROM {$wpdb->prefix}term_taxonomy WHERE parent =" . $v['id'];
                    $child_taxonomys = $wpdb->get_results($query);

                    // 检查子类 End

                    $collection_name = b2_get_option('normal_custom', 'custom_collection_name');
            ?>
