ECSHOP全站调用购物车显示商品图片,价格,数量,总价等详细信息

效果如图：

第一步: 在/thmes/你的模板/library/
新建一个库文件:  cart_info.lbi
代码:
复制代码
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<!-- {if $goods} -->
<div class="cat_ul" onMouseOver="this.className='cat_ul on'" onMouseOut="this.className='cat_ul'">
<div class="clearfix divt">
<p class="clearfix ptt">
<span class="cart_sp"><em class="left">{$goods_number} 件</em><em class="right"> ￥{$order_amount} 元</em></span><a href="flow.php" class="js">去结算</a>
</p></div>
<ul class="cart_box clearfix">
{foreach from=$goods item=goods name=goods key=key}
<li {if $key%2 neq 0}class="clearfix nobk"{else} class="clearfix"{/if}>
<span class="sgood left"><a href="{$goods.url}" ><img src="{$goods.goods_thumb}" alt="{$goods.goods_name}"></a></span>
<p class="left sgoodc"><a class="name" href="{$goods.url}">{$goods.short_name}</a>
<span>{$goods.goods_jj}</span>
</p>
<p class="right sgoodt">
<span>{$goods.goods_price}&times;{$goods.goods_number}</span><a class="del" href="javascript:" onClick="deleteCartGoods({$goods.rec_id})">[删除]</a></p>
</li>
{/foreach}
<li class="clearfix zllcart">
<span class="ie6left">共 <em>{$goods_number}</em> 件 <span class="pipe">|</span> 价格总计:<em> ￥{$order_amount} 元</em></span><a href="flow.php" class="right">去购物车结算>></a>
</li>
</ul>
</div>
<!-- {else} -->
<ul class="car_ul onp clearfix">
<p class="clearfix ptt">暂无商品</p>
<ul>
<!-- {/if} -->
复制代码
第二步打开: includes/lib_insert.php
大约102行 代码
复制代码
function insert_cart_info()
{
    $sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
           ' FROM ' . $GLOBALS['ecs']->table('cart') .
           " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
    $row = $GLOBALS['db']->GetRow($sql);
    if ($row)
    {
        $number = intval($row['number']);
        $amount = floatval($row['amount']);
    }
    else
    {
        $number = 0;
        $amount = 0;
    }
    $str = sprintf($GLOBALS['_LANG']['cart_info'], $number, price_format($amount, false));
    return '<a href="flow.php" title="' . $GLOBALS['_LANG']['view_cart'] . '">' . $str . '</a>';
}
复制代码
替换为如下代码
复制代码
function insert_cart_info()
{
    $sql = 'SELECT c.*,g.goods_name,g.goods_thumb,g.goods_id,c.goods_number,c.goods_price' .
           ' FROM ' . $GLOBALS['ecs']->table('cart') ." AS c ".
                                         " LEFT JOIN ".$GLOBALS['ecs']->table('goods')." AS g ON g.goods_id=c.goods_id ".
           " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
    $row = $GLOBALS['db']->GetAll($sql);
                $arr = array();
                foreach($row AS $k=>$v)
                {
                                $arr[$k]['goods_thumb']  =get_image_path($v['goods_id'], $v['goods_thumb'], true);
        $arr[$k]['short_name']   = $GLOBALS['_CFG']['goods_name_length'] > 0 ?
                                               sub_str($v['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $v['goods_name'];
                                $arr[$k]['url']          = build_uri('goods', array('gid' => $v['goods_id']), $v['goods_name']);
                                $arr[$k]['goods_number'] = $v['goods_number'];
                                $arr[$k]['goods_name']   = $v['goods_name'];
                                $arr[$k]['goods_price']  = price_format($v['goods_price']);
                                $arr[$k]['rec_id']       = $v['rec_id'];
                 }
    $sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
           ' FROM ' . $GLOBALS['ecs']->table('cart') .
           " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
    $row = $GLOBALS['db']->GetRow($sql);
    if ($row)
    {
        $number = intval($row['number']);
        $amount = floatval($row['amount']);
    }
    else
    {
        $number = 0;
        $amount = 0;
    }
    $GLOBALS['smarty']->assign('str',sprintf($GLOBALS['_LANG']['cart_info'], $number, price_format($amount, false)));
        $GLOBALS['smarty']->assign('goods',$arr);
        $GLOBALS['smarty']->assign('goods_number',$number);
        $GLOBALS['smarty']->assign('order_amount',$amount);
    $output = $GLOBALS['smarty']->fetch('library/cart_info.lbi');
    return $output;
}
复制代码
第三步: 打开js/common.js
最后面添加:
复制代码
// 自定义购物车删除
function deleteCartGoods(rec_id)
{
Ajax.call('delete_cart_goods.php', 'id='+rec_id, deleteCartGoodsResponse, 'POST', 'JSON');
}
/**
* 接收删除后返回的信息
*/
function deleteCartGoodsResponse(res)
{
  if (res.error)
  {
    alert(res.err_msg);
  }
  else
  {
      document.getElementById('ECS_CARTINFO').innerHTML = res.content;
  }
}
复制代码
第四步: 打开 thmes/你的模板/style.css
最后添加:
复制代码
 /*购物车*/
   .cart{ position:absolute; z-index:9px; right:0px; _right:-5px; top:4px; width:190px; padding-right:5px; height:26px; line-height:26px; 
   }
   .cart a.js{ text-indent:-999px; overflow:hidden; display:inline-block; height:26px; float:right; width:38px;}
   .cart_sp { display:block; float:left; height:26px; line-height:26px; width:150px;}
   .cart_sp .right {_width:70px; padding-right:10px;  text-align:right;}
   .cart_sp .left {_width:70px;text-indent:30px;}
   .cart_box { display:none;}
   .on .cart_box { display:block; background:#fff; border:1px solid #ddd; width:300px; margin:5px 0 0 -106px; _margin:5px -8px 0 0;}
   .ie6left {_float:left;}
   .ptt {background:url(images/suning.png) no-repeat 0 -80px;}
   .onp .ptt {text-indent:30px; }
   .on .ptt,.onp .ptt {_float:right; _width:195px; background-position:0px -80px;}
   .divt {_width:300px;}
   .cart_box li { height:auto; text-indent:0px; padding:8px; color:#777; border-bottom:1px dashed #dedede; _height:48px;}
   .cart_box li.nobk { background:#fafafa;}
   .cart_box li p.sgoodc { width:163px; overflow:hidden;}
   .cart_box li p.sgoodc span,.cart_box li p.sgoodt span,.cart_box li p a.del{ display:block; height:18px; line-height:18px; overflow:hidden;}
   .cart_box li p.sgoodt { width:65px; float:right; text-align:right; overflow:hidden; color:#ff6600;}
   .cart_box li p a.name { color:#333; text-decoration:none; height:22px; overflow:hidden;}
   .cart_box li p a:hover.name,.zllcart a:hover.right { text-decoration:underline;}
   .cart_box li p a.del { color:#777; text-decoration:none; margin-top:5px; }
   .cart_box li p a:hover.del { color:#333; text-decoration:line-through;}
   .cart_box li.zllcart { padding:0 8px; border-bottom:0;_height:24px;}
   .zllcart em,.zllcart a.right { color:#ff6600;text-decoration:none;}
复制代码
第五步,在根目录 新建一个delete_cart_goods.php文件
复制代码
<?php
define('IN_ECS', true);
require(dirname(__FILE__) . '/includes/init.php');
include_once('includes/cls_json.php');
$result = array('error' => 0, 'message' => '', 'content' => '', 'goods_id' => '');
$json  = new JSON;
if($_POST['id'])
{
$sql = 'DELETE FROM '.$GLOBALS['ecs']->table('cart')." WHERE rec_id=".$_POST['id'];
$GLOBALS['db']->query($sql);
}
$sql = 'SELECT c.*,g.goods_name,g.goods_thumb,g.goods_id,c.goods_number,c.goods_price' .
                         ' FROM ' . $GLOBALS['ecs']->table('cart') ." AS c ".
                         " LEFT JOIN ".$GLOBALS['ecs']->table('goods')." AS g ON g.goods_id=c.goods_id ".
                         " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
$row = $GLOBALS['db']->GetAll($sql);
$arr = array();
foreach($row AS $k=>$v)
{
                $arr[$k]['goods_thumb']  =get_image_path($v['goods_id'], $v['goods_thumb'], true);
                $arr[$k]['short_name']   = $GLOBALS['_CFG']['goods_name_length'] > 0 ?
                                                                                                                                                                         sub_str($v['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $v['goods_name'];
                $arr[$k]['url']          = build_uri('goods', array('gid' => $v['goods_id']), $v['goods_name']);
                $arr[$k]['goods_number'] = $v['goods_number'];
                $arr[$k]['goods_name']   = $v['goods_name'];
                $arr[$k]['goods_price']  = price_format($v['goods_price']);
                $arr[$k]['rec_id']       = $v['rec_id'];
}
$sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
                         ' FROM ' . $GLOBALS['ecs']->table('cart') .
                         " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
$row = $GLOBALS['db']->GetRow($sql);
if ($row)
{
                $number = intval($row['number']);
                $amount = floatval($row['amount']);
}
else
{
                $number = 0;
                $amount = 0;
}
$GLOBALS['smarty']->assign('str',sprintf($GLOBALS['_LANG']['cart_info'], $number, price_format($amount, false)));
$GLOBALS['smarty']->assign('goods',$arr);
$GLOBALS['smarty']->assign('goods_number',$number);
$GLOBALS['smarty']->assign('order_amount',$amount);
$result['content'] = $GLOBALS['smarty']->fetch('library/cart_info.lbi');
die($json->encode($result));
?>
复制代码
使用下面的代码即可全站调用购物车:
 {insert_scripts files='transport.js'}
<div class="cart" id="ECS_CARTINFO">
{insert name='cart_info'}
更新缓存即可!
