I implement the example from facebook credits, and create an test app, added the callback.php in the Callback Url, place my keys correctly. but I get this error:
Sorry, but we're having trouble processing your payment. You have not been charged for this transaction. Please try again.
I am trying to create a few buttons with different monetary values. Like:
Click to get 100 credits
Click to get 1000 credits
If I use this generic code, I get the payment window just fine, but I can't see my products there, I can only choose from already made presets :
function buyMore(){
// calling the API ...
var obj = {
app_id: 'xxxxxxxxxxxxxxxxxxxxx',
method: 'pay',
order_info: n,
purchase_type: 'item',
credits_purchase: true
};
to show the user my monetary presets I think I need to pass different values to the function:
<p><a onclick="buyMore('100'); return false;">Buy More Credits 100</a></p>
<p><a onclick="buyMore('1000'); return false;">Buy More Credits 1000</a></p>
function buyMore(price) {
var order_info = {
"title":'title',
"description":'description',
"price":price,
"image_url":'http://....img_url',
"product_url":'http://....product_url'
};
// calling the API ...
var obj = {
app_id: '153230661424821',
method: 'pay',
order_info: order_info,
purchase_type: 'item'
};
}
Not sure if I got it right.
Can anyone push me in the right direction?
Yeah, you'll have to have your users select the item they want to purchase, which will then call the buyMore function to have them confirm their purchase via the Credits dialog (like you're doing in your second example).
First thing I'd do is check my Credits setting in the Developer app though. I've gotten that error before on a new app before realizing I'd forgotten to set my credits callback URL or set my user as a Credits test user.
Why are you asking the user to buy a set number of credits?
Surely it's an easier flow if you ask the user to buy an item (priced in credits) and Facebook handles the step of the user buying the necessary credits themselves?

I need to show something only to users with active subscriptions, im using the edd recurring payments plugin, I found this is their docs
$subscriber->has_active_subscription()
But im not sure how to make use of it to show something only to users with active subscriptions.
So i will be adding this code in my archive.php file and show extra php code for active users.
that code you found is part of the OOP class used by Easy Digital Downloads. Their docs are here: https://docs.easydigitaldownloads.com/article/1160-recurring-payments-developer-eddrecurringsubscriber
What you'd need to do is something like:
$my_user = get_current_user_id(); //grab current user
$subscriber = new EDD_Recurring_Subscriber( $my_user, true ); //pass user id to EDD class
//The EDD class will return its own user object, and on that you can do your check from the question:
if ($subscriber->has_active_subscription()) {
echo 'some special message for users with subscriptions';
} else {
//do something else
}
Watch out though, because that method will return true both if user has an active subscription and if he/she has a cancelled subscription (but false if subscription has expired). That may or may not be what you want.
I don't have EDD so haven't tested this but I hope it at least gets you started.
I'm using PayPal and want to add the payment method SEPA on my current website.
Here are some examples I have followed:
https://developer.paypal.com/docs/checkout/integration-features/standalone-buttons/#funding-sources
https://demo.paypal.com/de/demo/go_platform/pcRestServerV2/paymentOptions
So basically I'm not getting SEPA button as displayed here on above 2nd link.
Here is my code that helps you to identify what I'm doing wrong.
var FUNDING_SOURCES = [
paypal.FUNDING.PAYPAL,
paypal.FUNDING.VENMO,
paypal.FUNDING.CREDIT,
paypal.FUNDING.CARD,
paypal.FUNDING.SEPA,
];
FUNDING_SOURCES.forEach(function(fundingSource) {
// Initialize the buttons
var button = paypal.Buttons({
fundingSource: fundingSource
});
// Check if the button is eligible
if (button.isEligible()) {
// Render the standalone button for that funding source
button.render('#paypalCheckoutContainer');
}
});
Is there a reason you are checking for and rendering particular funding sources? You can let PayPal handle that automatically instead of a forEach loop. Basically, use the simpler code at; https://developer.paypal.com/demo/checkout/#/pattern/client
If you are not located in a country that defaults to showing SEPA, add &buyer-country=DE to the SDK script query string line when testing in sandbox mode. Only do this for testing other countries in sandbox mode, it is not a valid parameter in live. The buyer's country will be auto detected in live.
My problem is, that second parameter in plgVmOnUpdateOrderPayment event is actually old status code before change.
Did anybody knows, how to get new status letter after changing order status via e.g. paypal plugin or in administration?
Aleš Pázner, yes the second parameter is always the old order status.
But you can use this piece of code:
function plgVmOnUpdateOrderPayment($virtuemart_order,$old_status) {
// getting the new status
// $virtuemart_order->order_status
return;
}

I have a social networking site built on a PHP framework. I'm using a plugin to award members points when they update their profile. Right now, whenever a member clicks on 'Save' it triggers the profileupdate event, and that event triggers the points being awarded. But, even if the profile fields are all empty, the event is still triggered and they still get points… so, my clever users are gaming the system to get points without really updating their profile :\
I want to add a function that checks that the profile fields aren't empty -- or, ideally, checks that a significant amount of changes have been made to at least 1 of the profile fields, but I'm not sure how to do that.
I'm still pretty new to PHP (about 1 year experience), so if anyone could help both with explaining what the checking process should be and the specifics on the code to execute the checking function, I'd really appreciate it!
Here are the current events and functions:
When the owner of the page clicks on 'Save', this is the event in the core of the PHP framework that gets triggered to notify the user of the update:
$owner->save();
trigger_event('profileupdate', $owner->type, $owner);
system_message(echo("profile:saved"));
This is the function in the points plugin that checks to see if the plugin is configured to award points based on a profile update, and then calls the points_add function to add points to the user:
function points_profile($event, $type, $object) {
if ($points = get_plugin_setting('profileupdate')) {
if (function_exists('points_add')) {
points_add(get_logged_in_user_guid(), $points, $event, $type, $object->entity_guid);
}
}
return(true);
}
This is an example of how the individual profile fields are defined/labelled -- ie, "admin_defined_profile_1"
if (save_config("admin_defined_profile_$id", $label) &&
save_config("admin_defined_profile_type_$id", $type) &&
save_config('profile_custom_fields', $fieldlist))
look on rowcount() http://www.php.net/manual/en/pdostatement.rowcount.php
it will -on single UPDATE -return 1 if anything was actually changed and 0 if nothing was changed.
I'm using Stripe for a payment gateway. I can successfully obtain a card's "token" as Stripe calls it, which is explained here: https://stripe.com/docs/checkout#api
Good to go with that. I successfully receive the token in my stripe dashboard. Now what I need to do is actually charge that card(token). Here is how they put it: "You've got your user's credit card details, now what? Now you charge them money. This happens on your server, and the fastest way to do it is by using one of our client libraries." Well they supply the php needed right on that page:
// Set your secret key: remember to change this to your live secret key in production
// See your keys here https://manage.stripe.com/account
Stripe::setApiKey("sk_test_68YYnDTKPzcxxRZbkxEJtOVq");
// Get the credit card details submitted by the form
$token = $_POST['stripeToken'];
// Create the charge on Stripe's servers - this will charge the user's card
try {
$charge = Stripe_Charge::create(array(
"amount" => 1000, // amount in cents, again
"currency" => "usd",
"card" => $token,
"description" => "payinguser#example.com")
);
} catch(Stripe_CardError $e) {
// The card has been declined
}
You can see exactly how they explain it here: https://stripe.com/docs/tutorials/charges
Here is where things go wrong.
1) Where in this code actually pinpoints what card to charge?! I have the card's token ID number in my private dashboard. I now need to charge it, but this code doesn't say anything about the card. The only spot I see is:
$token = $_POST['stripeToken'];
'stripeToken' do I put in the card's ID number here?
2)I've created a simple page to run this with:
<div id="payment">
<form action="charge-cards.php">
<?php require 'Stripe.php';?>
<input type="submit">
</form>
</div><!--end payment-->
"charge-cards.php" is the code at the top provided by Stripe. When I click submit, I get the follow error:
Fatal error: Class 'Stripe' not found in /home/preemin/public_html/fun.dit /testing/charge-cards.php on line 5
Can anyone see what I"m doing wrong? Thanks!
I think it's worthwhile to take a step back and review the basics. First, in order to provide a secure credit card transaction, and to ensure PCI compliance, Stripe has provided a javascript library that encrypts and transmits the sensitive credit card data. They provide an example form
Make careful note of the fact that the form has no submit action. Also pay special attention to the fact that none of the sensitive card fields have a name attribute. This form should never be submitted via any way other than the secure method they have provided. To try to do so opens you up to liability.
When you submit that form, using the js class they have provided (see Step 2), it gives you back a card token, which you say you already have. You can store that card token in your database without any security issues -- it's just an arbitrary number that means nothing to a hacker.
Once you have that token, you have two options:
use it immediately to make a one-time charge, or
store it and create a customer object that you can charge multiple times.
What you need to realize is that Stripe does NOT store that card token! If you lose it, you can't get it back. You have to generate a new one. Also, the only way you can use it for multiple charges is to create a customer object. In other words, UNLESS you store it on a customer object, it's only good for a single charge. So if you charge against it before attaching it to a customer object, it's no longer valid.
Now back to the basics again, as IOIO MAD described, there are two things you must do at the top of any php file that you want to call a Stripe method from:
include the Stripe php library
set the secret key
The only time the public key is used is when you're making that javascript call to submit the card form.
If you want to charge the card immediately, you have to turn right around and make a call back to the server, sending the card hash that you just got back. You might do this with ajax, or by sticking it in a form field that you then post. Step 3 shows you one way you might do this.
But lets assume that you want to do other things before actually charging the card. To expand on your example, lets say I have collected my customer's card on one page, then on my checkout page, I want to submit the charge:
<?php
require('path/to/Stripe.php'); // MUST be done before any Stripe:: call
Stripe::setApiKey("sk_test_mkGsLqEW6SLnZa487HYfJVLf");
// retrieve stored card hash. Could have got it to this page in any number of
// ways, including: stored in cookie, stored in session, stored in database.
// Let's assume stored in session for sake of simplicity of example
$cardHash = $_SESSION['stripeToken'];
?>
<div id="payment">
<form action="charge-cards.php">
<?php require 'Stripe.php';?>
<input name="stripeToken" type="hidden" value="<?= $cardHash ?>" />
<input type="submit">
</form>
</div>
When this form is submitted, charge-cards.php will get the $cardHash from the $_POST variable, whereupon you're going to follow the example given by Stripe:
<?php
require('path/to/Stripe.php'); // MUST be done before any Stripe:: call
Stripe::setApiKey("sk_test_mkGsLqEW6SLnZa487HYfJVLf");
// Get the credit card details submitted by the form
$token = $_POST['stripeToken'];
// Create the charge on Stripe's servers - this will charge the user's card
try {
$charge = Stripe_Charge::create(array(
"amount" => 1000, // amount in cents, again
"currency" => "usd",
"card" => $token,
"description" => "payinguser#example.com")
);
} catch(Stripe_CardError $e) {
// The card has been declined
}
?>
If you're still having problems, employ proper debugging skills to check whether or not your $_POST variable contains a card hash. If all else fails, contact Stripe customer support. Their API is top-notch, as is their documentation and support.
EDIT 4/15/13
OP is using the quick checkout method and using custom buttons. Most of the above still applies.
The code outlined in the Custom Buttons section assigns a click handler to the custom button, which returns a callback function that when executed, appends a hidden input to a form, assigns the stripeToken to that field, and submits the form. Just before the form is submitted, console.log or alert the stripeToken to make sure you have a legitimate value:
$('#customButton').click(function(){
var token = function(res){
var $input = $('<input type=hidden name=stripeToken />').val(res.id);
// alert the value of stripeToken
alert('stripeToken = ' + res.id);
$('form').append($input).submit();
};
This would be used in conjunction with this:
<form action="/charge" method="post">
<script src="https://checkout.stripe.com/v2/checkout.js" class="stripe-button"
data-key="pk_test_yourprivatekeyhere"></script>
</form>
So what should happen is after the user presses the checkout button, the form should have a hidden input field named 'stripeToken' which contains the token value. You can get that token from the form and submit it later. Alternatively, you can listen on the 'token' event, which will be bound to your button:
jQuery(function($){
var $button = $('#customButton');
$button.on('token', function(e, token){
$button.after('<hr /><p>Your Stripe token is: <strong>' + token.id + '</strong></p>');
});
});
DISCLAIMER: I haven't used the simple checkout method yet. This code is not tested
i think may be you are missing some "include" , Class 'Stripe' not found means that the PHP File consisting of Class 'Stripe' haven't included before the call#
Note : A PHP >= 5.2 environment is required
Download The Stripe PHP library
Extract it to your HOME!
Let’s create a file called config.php, where we’re going to set up some initial configuration.
<?php
require_once('./lib/Stripe.php');
$stripe = array(
"secret_key" => "sk_test_mkGsLqEW6SLnZa487HYfJVLf",
"publishable_key" => "pk_test_czwzkTp2tactuLOEOqbMTRzG"
);
Stripe::setApiKey($stripe['secret_key']);
?>
Then at your Code file ABOVE (assumes yours.php)
include "config.php";
// Get the credit card details submitted by the form
$token = $_POST['stripeToken'];
//rest as you go!
