以上是我在线学习的源代码，用于创建多维数组并提交给paypal进行处理。现在我尽量避免使用paypal，并希望将提交的数据插入我的新数据库'orders'。为此目的我创建了行（id（主要，自动增量），product_name，价格，数量，date_added），但我没有将数据插入其中....

我的尝试如下

$countArray = count($_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();
}

帮助~~~我需要知道我应该放入什么（isset（$ _ POST ['cartOutput']））{以便检索日期...我真的是初学者。我需要一些魔法......

Answer 1

我的例子使用PDO，但我认为你明白了，你也应该转移到PDO或MYSQLI而不是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

我看到你这样做了：amount_' . $x . '你的阵列文章将如下所示：

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

但如果你的写amount[]数组看起来像这样：

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

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

最后一个选项使得读取数组变得更好。

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();
} 
?>

正如您所看到的，在参数之前有ssd这些类型有4种类型：

i = intenger
s = string
d = double
b = blob

您必须始终定义此内容。

修改

你应该用这个：

<?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(); } ?>

Answer 2

1）您对pp_checkout_btn的表单操作仍显示“paypal web”。我认为这只是一个错字，所以请继续改变它。

2）此外，您的insert语句可以使用一些调整。请提供以下两个语句的结果，以构建一个确切的插入语句：

print_r($_POST) // once the data has been posted
echo $sql // place this just before calling exit

Answer 3

我认为您的插入代码应如下所示 $sql = mysql_query("INSERT INTO orders (product_name, price, quantity, date_added) VALUES('" . $_POST[$product_name] . "','" . $_POST[$price] . "','" . $_POST[$each_item['quantity']] . "', now())") or die (mysql_error());

编辑：
此外，for循环内的语句应为
$stmt->bind_param('ssd', $array[$product_name][$i], $array[$price][$i], $array[$each_item['quantity']][$i]);

Answer 4

以下是您应该参考的代码：

<?php 
// This file is www.developphp.com curriculum material
// Written by Adam Khoury January 01, 2011
// http://www.youtube.com/view_play_list?p=442E340A42191003
session_start(); // Start session first thing in script
// Script Error Reporting
error_reporting(E_ALL);
ini_set('display_errors', '1');
// 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'])) {
    $product_name=$_POST[$product_name];
    $price=$_POST[$price];
    $quantity=$_POST[$each_item['quantity']];
    $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]);
       $stmt->execute();
    } 

    echo $sql;

    exit();
}
?>

要检索日期：

$date = date('d/m/Y', time());

试试这个，看看它是否有效。
