下面要为各位提供一款PHP mysql的购物车实例程序完整购物代码，从数据库的安装到入库，以及完成商品交易，都一一的举了实例，好了费话不说多了我看看这款码吧。

代码如下

复制代码

if(!$session && !$scid) {
$session = md5(uniqid(rand()));
SetCookie("scid", "$session", time() + 14400);
} /* last number is expiration time in seconds, 14400 sec = 4 hrs */

class Cart {
function check_item($table, $session, $product) {
$query = "SELECT * FROM $table WHERE session='$session' AND product='$product' ";
$result = mysql_query($query);

if(!$result) {
return 0;
}

$numRows = mysql_num_rows($result);

if($numRows == 0) {
return 0;
} else {
$row = mysql_fetch_object($result);
return $row->quantity;
}
}

function delete_item($table, $session, $product) {
$query = "DELETE FROM $table WHERE session='$session' AND product='$product' ";
mysql_query($query);
}

function modify_quantity($table, $session, $product, $quantity) {
$query = "UPDATE $table SET quantity='$quantity' WHERE session='$session' ";
$query .= "AND product='$product' ";
mysql_query($query);
}

function clear_cart($table, $session) {
$query = "DELETE FROM $table WHERE session='$session' ";
mysql_query($query);
}

function display_contents($table, $session) {
$count = 0;
$query = "SELECT * FROM $table WHERE session='$session' ORDER BY id ";
$result = mysql_query($query);
while($row = mysql_fetch_object($result)) {
$query = "SELECT * FROM inventory WHERE product='$row->product' ";
$result_inv = mysql_query($query);
$row_inventory = mysql_fetch_object($result_inv);
$contents["product"][$count] = $row_inventory->product;
$contents["price"][$count] = $row_inventory->price;
$contents["quantity"][$count] = $row->quantity;
$contents["total"][$count] = ($row_inventory->price * $row->quantity);
$contents["description"][$count] = $row_inventory->description;
$count++;
}
$total = $this->cart_total($table, $session);
$contents["final"] = $total;
return $contents;
}

function num_items($table, $session) {
$query = "SELECT * FROM $table WHERE session='$session' ";
$result = mysql_query($query);
$num_rows = mysql_num_rows($result);
return $num_rows;
}

function quant_items($table, $session) {
$quant = 0;
$query = "SELECT * FROM $table WHERE session='$session' ";
$result = mysql_query($query);
while($row = mysql_fetch_object($result)) {
$quant += $row->quantity;
}
return $quant;
}
}
?>
