文章详情商品详细页调用当前子分类下的所有分类
先看效果：
操作方法：
第一：在goods.php的最下面添加一个function
//获取相关栏目的分类function get_categorys_info(https://www.ecshop.co/files/$parent_id){ https://www.ecshop.co/files/$sql = "SELECT * FROM " . https://www.ecshop.co/files/$GLOBALS['ecs']->table(https://www.ecshop.co/files/'category') . " WHERE parent_id=".https://www.ecshop.co/files/$parent_id." ORDER BY sort_order asc"; https://www.ecshop.co/files/$res = https://www.ecshop.co/files/$GLOBALS['db']->getAll(https://www.ecshop.co/files/$sql); https://www.ecshop.co/files/$categorys = array(); foreach (https://www.ecshop.co/files/$res AS https://www.ecshop.co/files/$idx => https://www.ecshop.co/files/$row){ https://www.ecshop.co/files/$categorys[https://www.ecshop.co/files/$idx]['id'] = https://www.ecshop.co/files/$row['cat_id']; https://www.ecshop.co/files/$categorys[https://www.ecshop.co/files/$idx]['url'] = build_uri(https://www.ecshop.co/files/'category', array('cid'=>https://www.ecshop.co/files/$row['cat_id']), https://www.ecshop.co/files/$row['cat_name']); https://www.ecshop.co/files/$categorys[https://www.ecshop.co/files/$idx]['name'] = https://www.ecshop.co/files/$row['cat_name']; } return $categorys;}第二：在然后我们需要获取这个栏目的父级，在顶部获取到这个栏目的父级
$cat_id = https://www.ecshop.co/files/$db->getOne("SELECT cat_id FROM " . https://www.ecshop.co/files/$ecs->table(https://www.ecshop.co/files/'goods') ." WHERE goods_id = '$goods_id' ");$parent_id = https://www.ecshop.co/files/$db->getOne("SELECT parent_id FROM " . https://www.ecshop.co/files/$ecs->table(https://www.ecshop.co/files/'category') . " WHERE cat_id = '$cat_id' ");第三：那么我们就拿$parent_id这个变量获取
$smarty->assign('categorys_info', get_categorys_info(https://www.ecshop.co/files/$parent_id)); https://www.ecshop.co/files/$smarty->assign('cat_id', https://www.ecshop.co/files/$cat_id);把他添加到smarty模板去赋值。
最后我们到我们自己的模板里面把他循环出来
{foreach from=$categorys_info item=r} {if $cat_id!=$r[id]} <li><a href="{$r.url}" title="{$r.name}">{$r.name}</a></li> {/if} {/foreach}很多人问为什么还要加个if去判断呢，因为你循环出来的是全部，你要把本身自己的栏目T出去。
