If we have price field options that have a maximum participant count it seems that they show up in a select list even if they are full? Looks like for every html type except select the full options are frozen. Instead for the select type a form rule is added to return an error if the user chooses that option.

So far I see that there is a function that checks if they are full: CRM_Event_BAO_Participant::priceSetOptionsCount() which is used by formatFieldsForOptionFull to add more info to the options array for each field including $optionFullIds. Then $optionFullIds is passed to CRM_Price_BAO_Field::addQuickFormElement as $feezeOptions unless the form is called CRM_Event_Form_Participant in order to ignore full options for offline registration. Except that for the select type they are added anyway and a form rule prevents submission if they are chosen.

      case 'Select':
        $selectOption = $allowedOptions = $priceVal = array();

        foreach ($customOption as $opt) {
          $count = CRM_Utils_Array::value('count', $opt, '');
          $max_value = CRM_Utils_Array::value('max_value', $opt, '');
          $priceVal[$opt['id']] = implode($seperator, array($opt[$valueFieldName], $count, $max_value));

          if ($field->is_display_amounts) {
            $opt['label'] .= ' - ';
            $opt['label'] .= CRM_Utils_Money::format($opt[$valueFieldName]);
          }
-          $selectOption[$opt['id']] = $opt['label'];

          if (!in_array($opt['id'], $feezeOptions)) {
            $allowedOptions[] = $opt['id'];
+          $selectOption[$opt['id']] = $opt['label'];
          }
        }
        $element = &$qf->add('select', $elementName, $label,
          array(
            '' => ts('- select -')) + $selectOption,
          $useRequired && $field->is_required,
          array('price' => json_encode($priceVal))
        );

        // CRM-6902
        $button = substr($qf->controller->getButtonName(), -4);
        if (!empty($feezeOptions) && $button != 'skip') {
          $qf->addRule($elementName, ts('Sorry, this option is currently sold out.'), 'regex', "/" . implode('|', $allowedOptions) . "/");
        }
        break;

-      //ignore option full for offline registration.
-      if ($className == 'CRM_Event_Form_Participant') {
-        $optionFullIds = array();
-      }
I have an event manager end user who would like the event registrants not to see the full options at all in the select list so that they don't get frustrated by choosing sold out options and I think they would like to at least retain the sold out warning in the offline registration. Any comments on the feasibility of just not showing the options at all by using an overridden version of CRM_Price_BAO_Field::addQuickFormElement and CRM_Event_Form_Registration_Register::formatFieldsForOptionFull()? Can anyone see any potential problems where this code is used elsewhere?

Is this solution still working for you? I agree with the frustration of choosing an option and typing in all your info, only to find out it is sold out when you submit. I was also considering, perhaps adding the words "sold out" to the option in the drop down. Is there a way in the  CRM_Price_BAO_Field file to add a if the option is 'frozen' add the text 'sold out' in the drop down?

Worked perfectly!!! Exactly what I needed, thank you!
