以上是我在网上学习的创建多维数组并提交到paypal处理的源码。现在我尽量避免使用贝宝，并想插入提交到我的新数据库“订单”的数据。我为此目的创建了行 (id (primary,auto increment),product_name,price,quantity,date_added) 但我未能将数据插入其中......

我的尝试如下

// Connect to the MySQL database

?>
<?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();
}
?>

帮助~~~我需要知道我应该输入什么 if (isset($_POST['cartOutput'])) { 为了检索日期......我真的是一个初学者。我需要一些魔法......

我的示例使用 PDO，但我认为您明白了，您还应该使用 PDO 或 MYSQLI 而不是 mysql

这个例子：

<?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

我看到您正在这样做：amount_' . $x . '您的数组帖子将如下所示：

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

但如果你写amount[]数组将如下所示：

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

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

最后一个选项可以更好地读取数组。

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ssd，参数前面有这些类型，有 4 种类型：

  • i = 整数
  • s = 字符串
  • d = 双倍
  • b = 斑点

您必须始终定义这一点。

编辑

你应该使用这个：

<?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();
}
?>

1) pp_checkout_btn 的表单操作仍显示“paypal web”。我认为这只是一个错字，所以请先更改它。

2）此外，您的插入语句可以使用一些调整。请提供以下两个语句的结果，以构建准确的插入语句：

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

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：
另外，循环内的语句for应该是
$stmt->bind_param('ssd', $array[$product_name][$i], $array[$price][$i], $array[$each_item['quantity']][$i]);

这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，然后看看它是否有效。
