How to force account creation before commerce checkout is complete?

Question

I currently have a one-page checkout that works great for anonymous users. After payment is complete, an account is created with the 'Create a new account for an anonymous order' checkout rule.

Now I need to add a subscription product to the site, and plan to use Commerce License and Commerce License Billing to sell a role. To handle recurring payments, I plan to use Commerce Card on File.

This introduces a problem because Card on File requires an authenticated user in order to save cards. See https://www.drupal.org/node/1553468

How can I create a user account before checkout finishes so that Card on File can properly save cards?

Ideally, there would be a custom checkout page that forces account registration as a first step in checkout, but only for users purchasing subscription products.

I don't allow visitors to register on the site at the moment (except via Commerce Checkout), and I'd rather not change that.

I suggest the following steps :

• create a custom checkout pane (see checkout_pane_example.module ) and embed the user register form in that pane:

  /**
   * Implements hook_commerce_checkout_pane_info().
   */
  function vts_register_commerce_checkout_pane_info() {
    $panes['register'] = array(
      'title' => t('Create an account'),
      'base' => 'vts_register_pane',
      'name' => t('NAME'),
      'page' => 'checkout',
      'weight' => -5,
    );
    return $panes;
  }
  /*
   * Add user_register_form to register pane
   */
  function vts_register_pane_checkout_form($form, &$form_state, $checkout_pane, $order) { 
    $pane_form = drupal_get_form('user_register_form');
    return $pane_form;
  }
  /*
   * Alter checkout form register pane
   */
  function vts_register_form_commerce_checkout_form_checkout_alter(&$form, &$form_state, $form_id) {
    unset($form['register']['actions']); 
  }
  /**
   * checkout form submission callback.
   */
  function vts_register_pane_checkout_form_submit($form, &$form_state, $checkout_pane, $order) {
    $new_user = array(
      //dsm to find the correct $form_state['input'] for username here, because I have an altered user register form...
      'name' => $form_state['input']['field_name_first']['und'][0]['value'].'_'.$form_state['input']['field_name_last']['und'][0]['value'],
      'pass' => user_password(),
      'mail' => $form_state['input']['mail'],
      'init' => $form_state['values']['mail'],
      'status' => 1,
      'roles' => array(DRUPAL_AUTHENTICATED_RID => TRUE),
    );
    if($GLOBALS['user']->uid == '0') {
      $user = user_save('', $new_user);
      //ASSIGN the current order to created user
      $order->uid = $user->uid;
      commerce_order_save($order);
      $GLOBALS['user'] = $user;
    }
    //check that you got a new user and the order was assigned to him
    dsm($user, 'user');
    dsm($order, 'order');
  }
  /**
   * Validation callback.
   */
  function vts_register_pane_checkout_form_validate($form, &$form_state, $checkout_pane, $order) {
    //validation stuff
    return TRUE;
  }
  /**
   * Ouputs Review checkout pane.
   */
  function vts_register_pane_review($form, $form_state, $checkout_pane, $order) {
    // add some info to review pane
    return;
  }
  

• Go to admin/commerce/config/checkout and set it as disabled

• Install Commerce Rules Extra, it adds the features you need :

Rules conditions : Total product of type quantity comparison

Rules actions : Change pane properties : Change visibility, page, weight of a pane

• Create a rule :
  • Event: Process checkout pane.
  • Conditions : user is anonymous ; subscription product quantity > 0.
  • Action : Change pane properties : enabled: true; move to checkout.

Answer 2

In addition to Kojo’s excellent solution, I might add that I believe the correct username input field for normal Drupal install is located in:

'name' => $form_state['input']['name']

The module still redirects to the new user profile page, but I will be investigating the cause further today.

Answer 3

There's a setting also a setting in drupalcommerce for drupal 8.

/admin/commerce/config/checkout-flows/manage/default

Now there you will see

Login or continue as guest

Click on gear icon, click and then uncheck Allow guest checkout.

That's all you need to do.

here is how i achieve to create the user_register_form commerce checkout pane :

/**
 * Implements hook_commerce_checkout_pane_info().
 */
function edw_commerce_dc_commerce_checkout_pane_info() {
  $panes['register'] = [
    'title' => t('Create an account'),
    'base' => 'edw_commerce_dc_register_pane',
    'name' => t('Authentication'),
    'file' => 'edw_commerce_dc.pane.inc',
    'page' => 'checkout',
    'weight' => -5,
  ];
  return $panes;
}

/*
 * Alter checkout form register pane
 */
function edw_commerce_dc_form_commerce_checkout_form_checkout_alter(&$form, &$form_state, $form_id) {
  unset($form['register']['actions']);
  if(isset($form['register'])){
    $form_id = 'user_register_form';
    $hooks = array('form');
    $hooks[] = 'form_' . $form_id;
    drupal_alter($hooks, $form['register'], $form_state, $form_id);
  }
}

    /*
 * Add user_register_form to register pane
 */
function edw_commerce_dc_register_pane_checkout_form($form, &$form_state, $checkout_pane, $order) {
  if (user_is_anonymous()) {
    $pane_form = drupal_retrieve_form('user_register_form', $form_state);
    $pane_form['#tree'] = FALSE;
    return $pane_form;
  }
}

/**
 * checkout form submission callback.
 */
function edw_commerce_dc_register_pane_checkout_form_submit($form, &$form_state, $checkout_pane, $order) {
  if (isset($form['register'])) {
    foreach ($form["register"]["#submit"] as $callback) {
      $callback($form['register'], $form_state);
    }
  }
}

/**
 * checkout form submission callback.
 */
function edw_commerce_dc_register_pane_checkout_form_validate($form, &$form_state, $checkout_pane, $order) {
  if (isset($form['register'])) {
    foreach ($form["register"]["#validate"] as $callback) {
      $callback($form['register'], $form_state);
    }
    if (!form_get_errors()) {
      return TRUE;
    }
  }
}
