如何將多維數組插入數據庫？

Question

我的陣列，即$ _SESSION [「cart_array」]包含

Array ([0] => Array ([item_id] => qwerty [quantity] => 2 [unit_price] => 500) [1] => Array ([item_id] => skjbm [quantity] => 3 [unit_price] => 100)) 

的代碼插入到我的數據庫的代碼是

foreach($_SESSION['cart_array'] as $each_item){ $sql=mysql_query("INSERT INTO product_added(id,ip_address,order_id,email,item_id,unit_price,quantity,total,pay_status)values('','','','','".$each_item['item_id']."','".$each_item['quantity']."','".$each_item['unit_price']."','','')"); 
if(!mysql_query($sql)){ 
    // maybe not the best use of `die` here? 
    die('Error: ' . mysql_error()); 
}echo "record added"; } 

我的問題是，當我運行該腳本將它添加只有一個項目，即：item_id = qwerty，數量= 2和unit_price = 500，因爲我在$_SESSION['cart_array']中有兩個項目。

和MySQL錯誤顯示：

Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1

如何進入二，多個項目進入數據庫？

試試這個。順便說一句mysql不贊成使用mysqli

$insert_query = 'INSERT INTO product_added (id,ip_address,order_id,email,item_id,unit_price,quantity,total,pay_status) values '; 

foreach($_SESSION['cart_array'] as $each_item){ 

    $insert_query .= "('','','','','".$each_item['item_id']."','".$each_item['quantity']."','".$each_item['unit_price']."','',''),";   

} 

$query = rtrim($insert_query, ','); 
if(!mysql_query($query)){ 
    die('Error: ' . mysql_error()); 
}else{ 
    echo "record added"; 
}
