I am trying to get Stripe's Checkout Custom Button to charge a credit card but all it does is minimize after I enter the credit card details. I am using the code found in the documentation but I can't get it to work. The simple button is easy to use and I figured it would be as easy as just customizing that one but it's very different.

Here's the code:

Payment Page

<form action="charge.php" method="post">
            <script src="https://checkout.stripe.com/checkout.js"></script>
            <input type="submit" value="Pay with card" id="customButton"/>
            <?php require_once('./config.php'); ?>
                <script>
                var handler = StripeCheckout.configure({
                    key: '<?php echo $stripe['publishable_key']; ?>',
                    image: 'favicon.png',
                    token: function(token, args) {
                    // Use the token to create the charge with a server-side script.
                    // You can access the token ID with `token.id`
                    }
                });

                document.getElementById('customButton').addEventListener('click', function(e) {
                    // Open Checkout with further options
                    handler.open({
                    name: 'Imprintnation',      
                    description: 'Decals',
                    amount: <?php echo $stripeTotal; ?>

                });
                    e.preventDefault();
                });
                </script>
                </form>

Charge Page(charge.php)

<?php
require_once(dirname(__FILE__) . '/config.php');

$token  = $_POST['stripeToken'];

$customer = Stripe_Customer::create(array(
  'email' => 'customer@example.com',
  'card'  => $token
));

$charge = Stripe_Charge::create(array(
  'customer' => $customer->id,
  'amount'   => 5000,
  'currency' => 'usd'
));

echo '<h1>Successfully charged $5!</h1>';
?>

Configuration Page(config.php)

<?php
require_once('./lib/Stripe.php');

$stripe = array(
secret_key      => 'sk_test_************************',
publishable_key => 'pk_test_************************'
);

Stripe::setApiKey($stripe['secret_key']);
?>

What am I missing here? I can't even get it to retrieve a token.

How can I retrieve a token and charge a card?

presumably you would have to set a callback page on stripe.com and direct them to your charge.php that would get you the token, im assuming stripe works similar to paypal, i did not checkandrew
This is directly from their documentation and it doesn't mention anything about setting up a callback page.Josan Iracheta
you could try var_dump($charge) to see if anything got returned. also check your server has a curl extension installed for php, it will need it to interact with their serverandrew
It appears they callBack to the same page from which you made the post so you're probably right, no need to configure that stripe.com/docs/tutorials/forms#create-a-single-use-tokenandrew

Finally got it to work. Had to change a bunch of it. Here is the code:

Payment page

<form action="charge.php" method="post">
<script src="https://checkout.stripe.com/checkout.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js"></script> 

<button id="customButton">Pay with Card</button>
<style>
#customButton{
width:300px;
height:50px;
background-color:orange;
color:white;
border:2px solid green;
}
</style>
 <script>
 $('#customButton').click(function(){
 var token = function(res){
 var $input = $('<input type=hidden name=stripeToken />').val(res.id);
 $('form').append($input).submit();
 };

 StripeCheckout.open({
 key:         '<?php echo $stripe['publishable_key']; ?>',
 address:     false,
 amount:      '<?php echo $price; ?>',
 currency:    'usd',
 name:        'test',
 description: '<?php echo $desc; ?>',
 panelLabel:  'Checkout',
 token:       token
 });

 return false;
 });
 </script>
 <input type="hidden" name="desc" value="<?php echo $desc; ?>"/>
 <input type="hidden" name="totalPrice" value="<?php echo $price; ?>"/>
</form>

charge.php

<?php
require_once(dirname(__FILE__) . '/config.php');

$token  = $_POST['stripeToken'];
$amount = $_POST['totalPrice'];
$desc = $_POST['desc'];
$percent = "0.01";
$realAmount = $amount * $percent;
try {       
$charge = Stripe_Charge::create(array(
    'card' => $token,
    'amount'   => $amount,  
    'currency' => 'usd',
    'description' => $desc
    ));

    } catch(Stripe_CardError $e) {
// The card has been declined
}

echo "<h1>Successfully charged $$realAmount!</h1>";
?>

I wish Stripe's documentation was more straightforward but this code handles the charge and it logs it on your dashboard.

@BlueSix is right, why do you have:

<input type="hidden" name="totalPrice" value="<?php echo $price; ?>"/>

Just because the value is hidden, does not mean it cannot be edited by the end user.

It would be much better to set $amount = $price directly, passing the variable through your application backend.
