Hi,

I'm trying to use the hook_civicrm_buildForm hook to adjust the total amount for a certain membership.

Here is the code:

function civicrm_abo_civicrm_buildForm($formName, &$form) {
    if ($formName == 'CRM_Member_Form_Membership') {
      if (array_key_exists('membership_id', $form->_defaultValues)) {
        $membershipId = $form->_defaultValues['membership_id'];
        $membershipTypeId = $form->_defaultValues['membership_type_id'][1];
        if ($membershipTypeId == 1) {
          // setting the default end date works ...
          $defaults['end_date'] = "01/01/2015";
          // setting the amount does not work ...
          $defaults['total_amount'] = "1.00";
          $form->setDefaults($defaults);                                                                                                       
        }
      }
    }
  }

Using the code above I'm able to adjust the end date of the membership by passing the new value to setDefaults(). However, this is not working for the amount (in Membership payment and Receipt section of the form). The amount that is displayed is still the amount that is defined in the membership type configuration. Is there a way to adjust the amount dynamically?

thanks,
