php购物车完整实现代码

本文介绍一个php实现的购物车代码功能实现比较完整实现了购物车、订货人信息、会员价等功能还是不错的有需要的朋友可以参考下

1、商品展示页面

复制代码代码如下:

<tablewidth="255"border="0" cel lspacing="0" cel lpadding="0">

<tr>

<td width="130" rowspan="6"><div al ign="center">

<?phpif(trim($info[tupian]==""))

{echo"暂无图片";

}else

{

?>

< imgsrc="<?php echo$info[tupian];?>"width="130"height="100"border="0"><?php

}

?>

</div></td>

<td width="20" height="16"></td>

<td width="113"><font color="EF9C3E"> 【<?php echo$info[mingcheng];?>】</font></td></tr>

<tr>

<td height="16"></td>

<td><font color="910800"> 【市场价 <?php echo$info[shichangji a];?>】</font></td></tr>

<tr>

<td height="16"></td>

<td><font color="DD4679"> 【会员价 <?php echo$info[huiyuanjia];?>】</font></td></tr>

<tr>

<td height="16"></td>

<td> 【<a href="lookinfo.php?id=<?php echo

$i nfo[id];?>">查看信息</a>】</td></tr>

<tr>

<td height="16"></td>

<td> 【<a href="addgouwuche.php?id=<?phpecho$i nfo[id];?>">放入购物车</a>】</td></tr>

<tr>

<td height="16"></td>

<td><font color="13589B"> 【剩余数量<?phpif(($info[shul iang]-$info[cishu])>0)

{echo($info[shul iang]-$info[cishu]);

}else

{echo"已售完";

}

?>】</font></td>

</tr>

</table>

<?php

}

?>

</table>

2、文件addgouwuche.php

复制代码代码如下:

<?phpsession_start();include("conn.php");

if($_SESSION[username]=="")

{echo"<script>alert('请先登录后购

物!');history.back();</script>"; exit;

}

$id=strval($_GET[id]);

$sql=mysql_query("select * from shangpin whereid='".$id."'",$conn); $info=mysql_fetch_array($sql);if($info[shul iang]<=0)

{echo"<script>alert('该商品已经售

完!');history.back();</script>";exit;

}

$array=explode("@",$_SESSION[producel ist]);for($i=0;$i<count($array)-1;$i++)

{if($array[$i]==$id)

{echo"<script>alert('该商品已经在您的购物车中!');history.back();</script>";exit;

}

}

$_SESSION[producel ist]=$_SESSION[producel ist].$id."@";

$_SESSION[quatity]=$_SESSION[quatity]."1@";header("location:gouwu1.php");

?>

3、文件gouwu1.php

复制代码代码如下:

<?phpsession_start();if($_SESSION[username]=="")

{echo"<script>alert('请先登录后购

物!');history.back();</script>";exit;

}

?>

<?phpinclude("top.php");

?>

<tablewidth="800" height="438"border="0" al ign="center"cel lpadding="0" cel lspacing="0"><tr>

<td width="200" height="438"val ign="top"

bgcolor="#E8E8E8"><div al ign="center">

<?phpinclude("left.php");?>

</div></td>

<td width="10"background="images/l ine2.gif"></td>

<td width="590"val ign="top"><tablewidth="550" height="10"border="0" al ign="center" cel lpadding="0" cel lspacing="0">

</tr>

</table>

</tr>

<tr>

<td bgcolor="#555555"><tablewidth="500"border="0"al ign="center" cel lpadding="0" cel lspacing="1">

<?php

session_start();session_register("total");if($_GET[qk]=="yes")

{

$_SESSION[producel ist]="";

$_SESSION[quatity]="";

}

$arraygwc=explode("@",$_SESSION[producel ist]);

$s=0;for($i=0;$i<count($arraygwc);$i++)

{

$s+=intval($arraygwc[$i]);

}if($s==0)

{echo"<tr>";echo"<td height='25' colspan='6'bgcolor='#FFFFFF' al ign='center'>您的购物车为空!</td>";echo"</tr>";

}else

{

?>
