1、创建物流库存表。sql语句：

CREATE TABLE IF NOT EXISTS `emws_materials` (`id` mediumint(8) unsigned NOT NULL auto_increment,`name` varchar(60) NOT NULL,`modulus` varchar(60) NOT NULL,`stock_number` smallint(5) unsigned NOT NULL default '0',`stock_in` smallint(5) unsigned NOT NULL default '0',`stock_out` smallint(5) unsigned NOT NULL default '0',`safe_day` smallint(5) unsigned NOT NULL default '0',`intent_day` smallint(5) unsigned NOT NULL default '0',`is_buy` tinyint(1) unsigned NOT NULL default '1',`buy_url` varchar(60) NOT NULL,`PRice` decimal(10,2) NOT NULL,`weight` smallint(5) unsigned NOT NULL default '0',`img` varchar(60) NOT NULL,`desc_info` varchar(60) NOT NULL,`remark` varchar(60) NOT NULL,`admin_id` smallint(5) unsigned NOT NULL,`update_time` int(10) unsigned NOT NULL,PRIMARY KEY (`id`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;

2、php程序，materials.php：

  1 <?php  2 define('IN_ECS', true);  3 require(dirname(__FILE__) . '/includes/init.php');  4 include_once(ROOT_PATH . 'includes/cls_image.php');  5 $image = new cls_image($_CFG['bgcolor']);  6 $exc = new exchange($ecs->table("materials"), $db, 'id', 'name');  7 $_REQUEST['act']=!empty($_REQUEST['act']) ? $_REQUEST['act']:'list';  8 admin_priv('stock_alert');//权限：库存数量修改  9 if($_REQUEST['act'] == 'list') 10 { 11     $stock_list=material_list(); 12     $smarty->assign('ur_here',      '物料库存列表'); 13     $smarty->assign('stock_list',     $stock_list['stock_list']); 14     $smarty->assign('filter',       $stock_list['filter']); 15     $smarty->assign('record_count', $stock_list['record_count']); 16     $smarty->assign('page_count',   $stock_list['page_count']); 17      18     $smarty->assign('shelf_list',     $shelf_list); 19     $smarty->assign('full_page',    1); 20     $smarty->assign('action_link',  array('href' => 'goods_stock.php?act=list', 'text' => '商品库存列表')); 21     $smarty->assign('action_link2',  array('href' => 'materials.php?act=export', 'text' => '导出采购单')); 22     $smarty->assign('action_link3',  array('href' => 'materials.php?act=add', 'text' => '添加物料')); 23      24     $smarty->display('material_list.htm'); 25 } 26 elseif($_REQUEST['act'] == 'add') 27 {     28     $smarty->assign('ur_here',      "添加物料"); 29     $smarty->assign('action_link', array('href' => 'materials.php?act=list', 'text' => '返回物料库存列表')); 30     $smarty->assign('form_action', "insert"); 31  32     assign_query_info(); 33     $smarty->display('material_info.htm'); 34 } 35 elseif($_REQUEST['act'] == 'insert') 36 { 37     $material['is_buy']    = isset($_REQUEST['is_buy']) ?
