上面是我在网上学到的用于创建多维数组并将其提交给paypal进行处理的源代码.现在，我尝试避免使用贝宝，并希望插入提交到我的新数据库订单"中的数据.为此，我创建了行(标识(主要，自动递增)，产品名称，价格，数量，日期已添加)，但是我无法将数据插入其中....

The above is the source code I learnt online to create a multidimensional array and submit to paypal for processing. Now I try to avoid paypal and wanna to insert the data submitted to my new database 'orders'. I created row (id (primary,auto increment),product_name,price,quantity,date_added) for this purpose but I failed to insert the data into it....

我的尝试如下

// Connect to the MySQL database  
include "storescripts/connect_to_mysqli.php"; 
?>
<?php 
// Parse the form data and add inventory item to the system
if (isset($_POST['cartOutput'])) { 
$product_name=mysqli_real_escape_string($myConnection,$_POST[' . $product_name . ']);
$price=mysqli_real_escape_string($myConnection,$_POST[' . $price . ']);
$quantity=mysqli_real_escape_string($myConnection,$_POST[$each_item['quantity']]);
$date = date('d/m/Y', time());
$sqlCommand = ""INSERT INTO orders (product_name, price, quantity, date_added) VALUES('" . $_POST[$product_name] . "','" . $_POST[$price] . "','" . $_POST[$each_item['quantity']] . "', now())";      

$sql = mysqli_query($myConnection,$sqlCommand) or die (mysqli_error());
$stmt = $mysqli->prepare($sql); 
$countArray = count($_SESSION["cart_array");
for ($i = 0; $i < $countArray; $i++) {
$stmt->bind_param('ssd', $array[$product_name][$i], $array[$price][$i], $array[$each_item['quantity']][$i],$array[$date][$i]);
   $stmt->execute();
} 



echo $sql   ; 

exit();
}
?>

HELP ~~~我需要知道if(isset($ _ POST ['cartOutput'])){为了获取日期，我该怎么办...我真的是一个初学者.我需要一些魔法……

HELP~~~ I need to know what shall I put in if (isset($_POST['cartOutput'])) { in order to retrieve the date...i am really a beginner. I need some magic......

推荐答案

我的示例使用PDO，但我认为您已经明白了，也应该使用PDO或MYSQLI代替mysql

My example use PDO but I think you get the idea, Also you should move to PDO or MYSQLI instead of mysql

示例:

<?php
// pdo example

$sql = 'INSERT INTO table (field1, field2, field3) VALUES (:value1, :value2, :value3)';

// $dbh is pdo connection
$insertTable = $dbh->prepare($sql);

$countArray = count($array);

for ($i = 0; $i < $countArray; $i++) {
   $insertTable->bindParam(':value1', $array['value1'][$i], PDO::PARAM_INT); // if value is int
   $insertTable->bindParam(':value2', $array['value2'][$i], PDO::PARAM_STR); // if value is str
   $insertTable->bindParam(':value3', $array['value3'][$i], PDO::PARAM_STR);
   $insertTable->execute();
}

?>

输入名称格式

我看到您正在执行此操作:amount_' . $x . '您的数组帖子将如下所示:

I see you are doing this: amount_' . $x . ' your array post will look like this:

[amount_0] => 100
[amount_1] => 200
[amount_2] => 1
[quantity] => 10
[quantity] => 20
[quantity] => 1

但是如果您写amount[]，则数组将如下所示:

but if your write amount[] the array will look like this:

[amount] => Array
    (
        [0] => 100
        [1] => 200
        [2] => 1
    )

[quantity] => Array
    (
        [0] => 10
        [1] => 20
        [2] => 1

最后一个选项使读取数组更好.

The last option makes it much better to read the array.

MYSQLI示例

<?php
$sql = 'INSERT INTO table (field1, field2, field3) VALUES (?, ?, ?)';
$stmt = $mysqli->prepare($sql); 

$countArray = count($array);

for ($i = 0; $i < $countArray; $i++) {
$stmt->bind_param('ssd', $array['value1'][$i], $array['value2'][$i], $array['value3'][$i]);
   $stmt->execute();
} 
?>

如您所见，在这些类型的参数之前有ssd，

As you can see there is standing ssd before the parameters these are the types there are 4 types:

• i =热情
• s =字符串
• d = double
• b = blob

您必须始终对此进行定义.

You must always define this.

修改

您应该使用此:

<?php 
// Parse the form data and add inventory item to the system
if (isset($_POST['cartOutput'])) { 

$sql= 'INSERT INTO orders (product_name, price, quantity, date_added) VALUES(?,?,?, NOW())';      

$stmt = $myConnection->prepare($sql); 
$countArray = count($_POST["item_name");
for ($i = 0; $i < $countArray; $i++) {
$stmt->bind_param('sss', $_POST['item_name'][$i], $_POST['amount'][$i], $_POST['quantity'][$i]);
$stmt->execute();
}

echo $sql   ; 

exit();
}
?>
