首页调用指定分类下子分类方法

模板首页一般都有分楼层显示的分类商品，，每个楼层右上角会有该分类下小分类排列显示的：

function get_parent_id_tree($parent_id){$three_c_arr = array();$sql = ‘SELECT count(*) FROM ‘ . $GLOBALS[‘ecs’]->table(‘category’) . " WHERE parent_id = ‘$parent_id’ AND is_show = 1 ";if ($GLOBALS[‘db’]->getOne($sql)){$child_sql = ‘SELECT cat_id, cat_name, parent_id, is_show ‘ .’FROM ‘ . $GLOBALS[‘ecs’]->table(‘category’) ."WHERE parent_id = ‘$parent_id’ AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC ";$res = $GLOBALS[‘db’]->getAll($child_sql);foreach ($res AS $row){if ($row[‘is_show’])$three_c_arr[$row[‘cat_id’]][‘id’] = $row[‘cat_id’];$three_c_arr[$row[‘cat_id’]][‘name’] = $row[‘cat_name’];$three_c_arr[$row[‘cat_id’]][‘url’] = build_uri(‘category’, array(‘cid’ => $row[‘cat_id’]), $row[‘cat_name’]);}}return $three_c_arr;}

<?php$this->assign(‘thiscid1’, get_parent_id_tree(17));//调用父级分类的下级分类?>

<!–{foreach from=$thiscid1 item=list name=name}–><A href="{$list.url}" target=_blank >{$list.name}</A> <!–{/foreach}–>

没有什么可凭仗，只有他的好身体，没有地方可去，只想到处流浪。
