ecshop首页调用指定分类下的商品
ecshop首页调用指定分类下的商品,这个功能是最近开发ecshop主题的时候需要的功能,就想百度糯米网一样分区域调用不同分类的商品,而ecshop里面,首页只能调用推荐加精等商品,确实很失望他的这些功能。
1、添加查询语句
在系统目录文件找到includes/lib_goods.php 这个文件打开在此页最底部加入以下函数代码:
/** * 首页获取指定分类产品 * * @access public * @param string * @param array * @return array */ function get_cat_id_goods_list($cat_id = '', $num = '') { $sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' . "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, " . "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, " . "g.is_best, g.is_new, g.is_hot, g.is_promote " . 'FROM ' . $GLOBALS ['ecs']->table ( 'goods' ) . ' AS g ' . 'LEFT JOIN ' . $GLOBALS ['ecs']->table ( 'category' ) . ' AS c ON c.cat_id = g.cat_id ' . "LEFT JOIN " . $GLOBALS ['ecs']->table ( 'member_price' ) . " AS mp " . "ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' " . "Where g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 " . $sql .= " AND (c.parent_id =" . $cat_id . " OR g.cat_id = " . $cat_id . " OR g.cat_id " . db_create_in ( array_unique ( array_merge ( array ( $cat_id ), array_keys ( cat_list ( $cat_id, 0, false ) ) ) ) ) . ")"; $sql .= " LIMIT $num"; $res = $GLOBALS ['db']->getAll ( $sql ); $goods = array (); foreach ( $res as $idx => $row ) { $goods [$idx] ['id'] = $row ['article_id']; $goods [$idx] ['id'] = $row ['goods_id']; $goods [$idx] ['name'] = $row ['goods_name']; $goods [$idx] ['brief'] = $row ['goods_brief']; $goods [$idx] ['brand_name'] = $row ['brand_name']; $goods [$idx] ['goods_style_name'] = add_style ( $row ['goods_name'], $row ['goods_name_style'] ); $goods [$idx] ['short_name'] = $GLOBALS ['_CFG'] ['goods_name_length'] > 0 ? sub_str ( $row ['goods_name'], $GLOBALS ['_CFG'] ['goods_name_length'] ) : $row ['goods_name']; $goods [$idx] ['short_style_name'] = add_style ( $goods [$idx] ['short_name'], $row ['goods_name_style'] ); $goods [$idx] ['market_price'] = price_format ( $row ['market_price'] ); $goods [$idx] ['shop_price'] = price_format ( $row ['shop_price'] ); $goods [$idx] ['thumb'] = empty ( $row ['goods_thumb'] ) ? $GLOBALS ['_CFG'] ['no_picture'] : $row ['goods_thumb']; $goods [$idx] ['goods_img'] = empty ( $row ['goods_img'] ) ? $GLOBALS ['_CFG'] ['no_picture'] : $row ['goods_img']; $goods [$idx] ['url'] = build_uri ( 'goods', array ( 'gid' => $row ['goods_id'] ), $row ['goods_name'] ); } return $goods; }
2、输出到模版
打开系统根目录下index.php文件加入如下代码,如果要在别的页面调用加到别的页面:
$smarty->assign('cat_id_goods_list_86', get_cat_id_goods_list(86,9)); // 指定商品调用 //其中86指的调用的栏目ID,9指的是调用商品的数量。
3、在模版中调用
在首页模版中调用即可,如下:
<!--{foreach from=$cat_id_goods_list_86 item=goods}--> <li><a href="{$goods.url}" target="_blank"><img src="{$goods.thumb}" alt="{$goods.name|escape:html}" /></a> <span class="a_title"><a href="{$goods.url}" title="{$goods.name|escape:html}" target="_blank">{$goods.short_style_name}</a></span> <div style="text-indent: 5px;">市场价 <span class="del">{$goods.market_price}</span> </div> <div style="text-indent: 5px;"><span class="red">售 价 {$goods.shop_price}</span></div></li> <!--{/foreach}-->
其实如果想要在其它的页面使用这个功能,只需要将第二部的代码复制到该页面对应的php文件即可。
