Hello,
This is the code I've been using for a decade:
HTML:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="textarea" id="euroAmount" name="amount" value="" placeholder="How much to spend.."/><br/>
<input type="hidden" name="cmd" value="_xclick"/>
<input type="hidden" name="business" value="mymail"/>
<input type="hidden" name="lc" value="en_US"/>
<input type="hidden" name="item_name" value="Item at mysite"/>
<?php echo '<input type="hidden" name="custom" value="'.$user_id.'">'; ?>
<input type="hidden" name="button_subtype" value="products"/>
<input type="hidden" name="currency_code" value="EUR"/>
<input type="hidden" name="no_shipping" value="1"/>
<input type="hidden" name="no_note" value="1"/>
<input type="hidden" name="notify_url" value="https://mysite/ipn.php"/>
<input type="hidden" name="return" value="https://mysite/shop"/>
<input type="hidden" name="rm" value="0"/>
<input type="hidden" name="bn" value="PP-BuyNowBF:btn_buynowCC_LG.gif:NonHostedGuest"/>
<input type="submit" class="btn btn-success" name="submit" value="Purchase with paypal"/><br/>
</form>
PHP:
<?php
if(gethostbyaddr($_SERVER['REMOTE_ADDR']) != 'notify.paypal.com'){
exit();
}
// Variables //
$receiverEmail = htmlspecialchars(strtolower($_REQUEST['receiver_email']));
$paymentStatus = htmlspecialchars(strtolower($_REQUEST['payment_status']));
$account_id = (int)$_REQUEST['custom'];
$time = (int)time();
$transaction_id = htmlspecialchars($_REQUEST['txn_id']);
$transaction_type = htmlspecialchars($_REQUEST['txn_type']);
$money_gross = (int)$_REQUEST['mc_gross'];
$money_fee = (int)$_REQUEST['mc_fee'];
$money_net = (int)($money_gross-$money_fee);
$money_currency = htmlspecialchars(strtolower($_REQUEST['mc_currency']));
$payer_email = htmlspecialchars($_REQUEST['payer_email']);
$payer_id = htmlspecialchars($_REQUEST['payer_id']);
$first_name = htmlspecialchars($_REQUEST['first_name']);
$last_name = htmlspecialchars($_REQUEST['last_name']);
// Setup
$receiver = 'mymail';
if($paymentStatus == 'completed' && ($receiverEmail == $receiver) && $money_gross > 0 && $money_currency == "eur"){
//allowed payment, giving the user whatever was ordered
}elseif($paymentStatus == 'reversed' && ($receiverEmail == $receiver)){
//do something
}else{
exit();
}
?>
I've tried to look into manuals for the new smart checkout, but to be honest, there's A LOT of things there and since I'm not used to those new things I don't even know where to look.
All I need is a HTML/PHP system there the amount of EUR is changeable depending on how much the user wants to purchase for.
To make this easier to understand, I let users "add balance" to my website.
So that's what I want and need, a friendly code that allow the user to edit how much he'd like to add to balance and that the balance is refilled automatically and quickly.
I'm sorry for sounding like a complete noob, but these new things are so confusing, especially when it seems like most of it is for carts of physical item sellers.
Sincerely, Mike
