?

代碼:

<?php?
/**?
* 根據Cookie值對購物車商品數量和總價格調用?
*/?
require("class/connect.php");?

$totalProducts = 0; //購物車商品總數?
$totalPrice = 0.0; //購物車商品總價?

// |77,243|2!|77,237|3!?
$cookieString = explode("!",$_COOKIE['zeuqcmybuycar']);?

try{?
//遍歷商品?
for($i = 0; $i < count($cookieString)-1; $i++){?
$priceAndNumber = explode("|",$cookieString[$i]);?
$thisNum = $priceAndNumber[2]; //當前商品的數量?
$thisId = explode(",",$priceAndNumber[1]);?
$thisId = $thisId[1]; //當前商品的ID?
$thisPrice = this_price($thisId); //當前商品價格?

$totalPrice += $thisPrice * $thisNum; //購物車商品總價累加?
$totalProducts += $thisNum; //購物車商品總數累加?
}?

echo "document.write("".displayResultJs($totalPrice,$totalProducts)."")"; //顯示結果Js形式輸出?

}catch (Exception $e){?
echo $e->getMessage();?
}?

/**計算商品價格*/?
function this_price($id){?
$connect = connectDB();?
$query = "select price from phome_ecms_news where id = ".$id;?
if(!$connect){?
throw new Exception("數據庫鏈接不成功,請檢查!");?
}?
if(!$result = $connect -> query($query)){?
throw new Exception("查詢失敗!");?
}?
$row = $result -> fetch_assoc();?

return $row['price'];?
}?

/**鏈接數據庫*/?
function connectDB(){?
global $phome_db_server,$phome_db_username,$phome_db_password,$phome_db_dbname,$phome_db_char;?
$connect = new mysqli($phome_db_server,$phome_db_username,$phome_db_password,$phome_db_dbname);?
$connect -> query("set Names ".$phome_db_char);?
return $connect;
}?

/**顯示結果Js*/?
function displayResultJs($totalPrice,$totalProducts){?
return "<div class='car'>您的購物車中有 {$totalProducts} 件商品，總計金額 ￥{$totalPrice}元。
點擊查看 <a href='/e/ShopSys/buycar/'>結算&gt;&gt;</a> </div>";?
}?
?>
