ECSHOP首页调用指定商品分类下级子分类导航

在文件 includes/lib_goods.php 最后加上 //*** 调用商品分类指定分类下级分类 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 $three_c_arr; } 如图： 声明后用$smarty调用，就是在index.php中加上下面一句： $smarty->assign('get_parent_id16_tree', get_parent_id_tree(16));//调用父级分类6的下级分类 最后就可以在index.dwt模板文件里开始调用了 {$list.name|truncate:15:true}  |
