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....

my attempt as below

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......

回答1:

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

the example:

<?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(); }  ?> 

Input name format

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 

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 

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

MYSQLI example

<?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(); }  ?> 

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

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

You must always define this.

Edit

You should use this:

<?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(); } ?> 

回答2:

1) Your form action for pp_checkout_btn still shows "paypal web". I think that's just a typo, so please go ahead and change that first.

2) Moreover, your insert statement can use a little tweaks. Please provide results for the following two statements, for framing an exact insert statement:

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

回答3:

I think your insert code should be as below
$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());

Edit:
Also, the statement inside for loop should be
$stmt->bind_param('ssd', $array[$product_name][$i], $array[$price][$i], $array[$each_item['quantity']][$i]);

Here is the code you should refer to:

To retrieve the date:

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

Try this and then see if it works.
