CiviCRM Community Forums (archive)

In case somebody stumbles upon this and needs help here is what I ended up doing:

1. I added a dummy choice to our price set, moved it to the top of the list and marked it as default (although I don't see an effect of having a default).

2. Created some javascript in files/civicrm/custom/tpl/CRM/Contribute/Form/Contribution/Main.extra.tpl to hide that element  - cj('div.Member_Class-row1').hide();

3. Added a hook_validateForm function to complain to the user if that hidden choice is still selected

function MyCustomModule_CiviCRM_civicrm_validateForm( $formName, &$fields, &$files, &$form, &$errors )
{
  //drupal_set_message("form name " . $formName);
  if ($formName == 'CRM_Contribute_Form_Contribution_Main') {
    //drupal_set_message("<pre>".print_r($fields,1)."</pre>");
    // hate to hard code this, but looks like the only way
    if ($fields['price_22'] == 68) {
      $form->setElementError('price_22', "Member Class is a required field");;
    }

  }
}

This is really hokey, so if somebody has a better solution, please mention it!
