Is it possible to restict payment methods to user groups?

The site i'm working on for a friend will eventually allow business accounts to purchase through the online store. This will require the use of a payment method other than "Credit Card". This other payment method would then need to be accessible to only the users in that particular group.

Any ideas?

See if you can grok this code from the recurring fee module I'm working on... it uses hook_form_alter() to remove improper payment methods from the form. In your case, you'd need to change the logic that determines what to remove:

<?php
function uc_recurring_form_alter($form_id, &$form) {
  // We may need to alter the checkout form to remove invalid payment methods.
  if ($form_id == 'uc_cart_checkout_form' && isset($form['panes']['payment'])) {
    $order->products = uc_cart_get_contents();

    // Make no changes if no recurring fees are found.
    if (uc_recurring_find_fees($order) == array()) {
      return;
    }

    // Remove invalid payment methods from the payment pane.
    $valid = variable_get('uc_recurring_payment_methods', array());
    foreach (array_keys($form['panes']['payment']['payment_method']['#options']) as $key) {
      if (!isset($valid[$key]) || $valid[$key] === 0) {
        unset($form['panes']['payment']['payment_method']['#options'][$key]);
      }
    }

    $count = count($form['panes']['payment']['payment_method']['#options']);
    if ($count == 0) {
      // Display an error message if no payment methods remain.
      drupal_set_message(t('There are no payment methods configured for orders with recurring fees!'), 'error');
      drupal_set_message(t('Please contact an administrator to solve the issue.'), 'error');
    }
    elseif ($count == 1) {
      // If only one payment method remains, make it the default.
      $form['panes']['payment']['payment_method']['#default_value'] = array_pop(array_keys($form['panes']['payment']['payment_method']['#options']));
    }
  }
}
?>

howdy,

I'm having trouble setting up conditional payment methods. I'd like to restrict bank transfer and check/money order payment methods to users with a particular second level domain (ie. school.nz).

I'm having trouble grokking Ryan's code:

<?php
function emailcheck_form_alter($form_id, &$form) {
  // We may need to alter the checkout form to remove invalid payment methods.
  if ($form_id == 'uc_cart_checkout_form' && isset($form['panes']['payment'])) {
 
    // I'll have to get some regex together to validate against a users email address variable - but that is another issue...

    if users email contains school.nz {

    print all payment methods; //how do I print out this bit?

else {

print only credit card & paypal; //and this bit?


}
}
}
?>

any clues would be much appreciated!
