With Drupal 6 CiviCRM 3.0.2, using hook_civicrm_buildForm I can adjust a priceset's price values to add a surcharge for CC processing. This code I setup to work whether the charge is initiated by the event participant or by the site admin, using the Create Event Registration feature.

The feature requested now is to only add the surcharge when the admin adds a registration paid for by Credit Card and to not add it if the admin selects Check.

I do not see any way to do this via the API.

Is there one?

Thanks.

As discussed on IRC, the civicrm_buildAmount hook does not appear be called when submitting an Event Registration from a URL like:

 civicrm/contact/view/participant?reset=1&action=add&cid=43&context=participant.

Lobo, you suggested I use hook_civicrm_buildForm after this form is submitted, but I don't see in $form (i.e. after the form is submitted) where it is that I could adjust the price set values. Here is the code I use in buildForm when that URL is requested via GET:

function mymodule_civicrm_buildForm( $formName, &$form ) {
  if ('CRM_Event_Form_Registration_Register' == $formName ||
      ('CRM_Event_Form_Participant' == $formName && isset($form->_priceSet))
      ) {
  foreach($form->_values['fee']['fields'] as $k => $fields) {
    foreach($fields['options'] as $k2 => $options) {
      $form->_priceSet['fields'][$k]['options'][$k2]['value'] = (1*$form->_priceSet['fields'][$k]['options'][$k2]['value'])+2.5;
      $form->_priceSet['fields'][$k]['options'][$k2]['name'] = (1*$form->_priceSet['fields'][$k]['options'][$k2]['name'])+2.5;
      $form->_values['fee']['fields'][$k]['options'][$k2]['value'] = (1*$form->_values['fee']['fields'][$k]['options'][$k2]['value'])+2.5;
      $form->_values['fee']['fields'][$k]['options'][$k2]['name'] = (1*$form->_values['fee']['fields'][$k]['options'][$k2]['name'])+2.5;
    }
  }
  foreach($form->_elements as $k => $element) {
    if (isset($element->_attributes['price'])) {
      $t = split('_',$element->_attributes['price']);
      $form->_elements[$k]->_attributes['price'] = $t[0] . '_' . ((1*$t[1])+2.5);
    }
  }

  return true;
I looked through print_r($form) in that hook after the form is submitted, but I haven't yet found where the price is located. Perhaps you know where it is?

I will look again tomorrow with fresh eyes also.
