Programmatically creating an order in Drupal Commerce for anonymous users redirecting to payment page

Question

Ryan has some great code that you can programmatically create an order

<?php
global $user;
$product_id = 1;
// Create the new order in checkout; you might also check first to
// see if your user already has an order to use instead of a new one.
$order = commerce_order_new($user->uid, 'checkout_checkout');

// Save the order to get its ID.
commerce_order_save($order);

// Load whatever product represents the item the customer will be
// paying for and create a line item for it.
$product = commerce_product_load($product_id);
$line_item = commerce_product_line_item_new($product, 1, $order->order_id);

// Save the line item to get its ID.
commerce_line_item_save($line_item);

// Add the line item to the order using fago's rockin' wrapper.
$order_wrapper = entity_metadata_wrapper('commerce_order', $order);
$order_wrapper->commerce_line_items[] = $line_item;

// Save the order again to update its line item reference field.
commerce_order_save($order);

// Redirect to the order's checkout form. Obviously, if this were a
// form submit handler, you'd just set $form_state['redirect'].
drupal_goto('checkout/' . $order->order_id);
?>

I have a site where I want to take anonymous donations so I have two problems.

1. If a user is not logged into the site they get an access denied message
2. The checkout process asks for name, address etc.

What I want to do is have a page where you confirm the amount then get taken to the payment page. In this case I am using PayPal WPS so redirecting there would be great.

Any advice you could give would be appreciated.

Answer 1

You may try to test a new module called Commerce Drush which has the following syntax:

drush commerce-order-add 1
drush --user=admin commerce-order-add MY_SKU123

Manual solution

For creating an order programatically in Commerce, you can use the following code (it works with drush as well, e.g. drush -vd -u "$1" scr order_code-7.php). Please note that commerce_payment_example module is required.

<?php

  if (!function_exists('drush_print')) {
    function drush_print ($text) {
      print $text . "\n";
    }
  }

  $is_cli = php_sapi_name() === 'cli';

  global $user;

  // Add the product to the cart
  $product_id = 5;
  $quantity = 1;

  if ($is_cli) {
    drush_print('Creating new order for ' . $quantity . ' item(s) of product ' . $product_id . '...');
  }

  // Create the new order in checkout; you might also check first to
  // see if your user already has an order to use instead of a new one.
  $order = commerce_order_new($user->uid, 'checkout_checkout');

  // Save the order to get its ID.
  commerce_order_save($order);

  if ($is_cli) {
    drush_print('Order created. Commerce order id is now ' . $order->order_id);
    drush_print('Searching product ' . $product_id . ' in a Commerce system...');
  }

  // Load whatever product represents the item the customer will be
  // paying for and create a line item for it.
  $product = commerce_product_load((int)$product_id);

  if((empty($product->product_id)) || (!$product->status)){
    if ($is_cli) {
      drush_print('  Cannot match given product id with a Commerce product id.');
    }

    drupal_set_message(t('Invalid product id'));
    drupal_goto(); // frontpage
    return FALSE;
  }

  if ($is_cli) {
    drush_print('  Found a Commerce product ' . $product->product_id . '.');
  }

  // Create new line item based on selected product
  $line_item = commerce_product_line_item_new($product, 1, $order->order_id);

  if ($is_cli) {
    drush_print('  Added product to the cart.');
  }

  // Save the line item to get its ID.
  commerce_line_item_save($line_item);

  // Add the line item to the order using fago's rockin' wrapper.
  $order_wrapper = entity_metadata_wrapper('commerce_order', $order);
  $order_wrapper->commerce_line_items[] = $line_item;

  if ($is_cli) {
    drush_print('Saving order...');
  }

  // Save the order again to update its line item reference field.
  commerce_order_save($order);

  // Redirect to the order's checkout form. Obviously, if this were a
  // form submit handler, you'd just set $form_state['redirect'].

  if ($is_cli) {
    drush_print('Checking out the order...');
  }

  commerce_checkout_complete($order);

  if ($is_cli) {
    drush_print('Marking order as fully paid...');
  }

  $payment_method = commerce_payment_method_instance_load('commerce_payment_example|commerce_payment_commerce_payment_example');

  if (!$payment_method) {
    if ($is_cli) {
      drush_print("  No example payment method found, we can't mark order as fully paid. Please enable commerce_payment_example module to use this feature.");
    }
  }
  else {
    if ($is_cli) {
      drush_print("  Creating example transaction...");
    }

    // Creating new transaction via commerce_payment_example module.
    $charge      = $order->commerce_order_total['und'][0];

    $transaction = commerce_payment_transaction_new('commerce_payment_example', $order->order_id);
    $transaction->instance_id = $payment_method['instance_id'];
    $transaction->amount = $charge['amount'];
    $transaction->currency_code = $charge['currency_code'];
    $transaction->status = COMMERCE_PAYMENT_STATUS_SUCCESS;
    $transaction->message = 'Name: @name';
    $transaction->message_variables = array('@name' => 'Example payment');

    if ($is_cli) {
      drush_print("  Notifying Commerce about new transaction...");
    }

    commerce_payment_transaction_save($transaction);

    commerce_payment_commerce_payment_transaction_insert($transaction);
  }

  if ($is_cli) {
    drush_print("Marking order as completed...");
  }

  commerce_order_status_update($order, 'completed');

  if ($is_cli) {
    drush_print("\nDone.");
  }

Note: As suggested in the comment, if you got error about payment method is unknown while saving the order, make sure you've specified it, e.g.

$order->data['payment_method'] = 'commerce_payment_example|commerce_payment_commerce_payment_‌​example';
commerce_order_save($order); 

Answer 2

This modified script works also for the anonymous users:

<?php
global $user;

$product_id = 2;
// Create the new order in checkout; you might also check first to
// see if your user already has an order to use instead of a new one.
$order = commerce_order_new($user->uid, 'checkout_checkout');
// Save the order to get its ID.
commerce_order_save($order);

// Link anonymous user session to the cart
if (!$user->uid) {
    commerce_cart_order_session_save($order->order_id);
}

// Load whatever product represents the item the customer will be
// paying for and create a line item for it.
$product = commerce_product_load($product_id);
$line_item = commerce_product_line_item_new($product, 1, $order->order_id);

// Save the line item to get its ID.
commerce_line_item_save($line_item);

// Add the line item to the order using fago's rockin' wrapper.
$order_wrapper = entity_metadata_wrapper('commerce_order', $order);
$order_wrapper->commerce_line_items[] = $line_item;

// Save the order again to update its line item reference field.
commerce_order_save($order);

// Redirect to the order's checkout form. Obviously, if this were a
// form submit handler, you'd just set $form_state['redirect'].
drupal_goto('checkout/' . $order->order_id);

Answer 3

You need to add commerce_cart_order_session_save() so anonymous user have their session to link the browser with cart content.

Answer 4

1. If a user is not logged into the site they get an access denied message

I got something working but I highly doubt it is best practice.

In the end I cheated. On my form where you put your details including email address I create a user account on the fly and then log the user in. If an email address is all ready in use I log the user in. (I make sure you are not using the admin email address).

As my site only has the donation form page when you hit that page it makes sure you are logged out (if you are not admin). On a successful transaction it logs you out. I have turned off order history / put redirects in place so you can only go on the pages I know about when logged in. No personal details are stored and can't see past donations

In my situation I am happy with how this works. It is not ideal and will only work in a few cases.

2. The checkout process asks for name, address etc.

I went to

/admin/commerce/config/checkout

And disabled

• Account information
• Billing information
