Do we have the ability to give group discounts for events yet?

can you elaborate on what you mean? if by group discounts via additional participant feature,...

lobo

Yes. I meant discounts for additional participants.

I made a quick hardcoded fix for this functionality on the file .../CRM/Event/Form/Registration/Confirm.php in the function 'public function buildQuickForm( )' definition. Of course I used it for just one event to which the discount is applied. The proper method would be to add an entry to the database with a value like 'isSpecialDiscount' and get the info for the event from its id. But this is just a temporary fix.

You should also add some info in the 'statusmsg' variable on the .../CRM/Event/Form/Registration/Register.php file to make your users know that all discounts will be applied at the end of the transaction.

It worked great for me and i've tested it multiple times. Use it at your own risk. No guaratees.

I changed the part where it says 

foreach( $this->_params as $k => $v ) {
                if ( is_array( $v ) ) {
                    if ( CRM_Utils_Array::value( 'is_primary', $v ) ) {               
                        $this->set( 'primaryParticipantAmount',$v['amount'] );
                    }       
                    $this->_amount[ $v['amount_level'].' - '. $v['email-5'] ] = $v['amount'];
          $this->_totalAmount = $this->_totalAmount + $v['amount'];
                }
            }

I changed it to the following:

foreach( $this->_params as $k => $v ) {
                if ( is_array( $v ) ) {
                    if ( CRM_Utils_Array::value( 'is_primary', $v ) ) {
                  //modification starts
                  //special discount for additional participants.
                  require_once 'CRM/Event/BAO/EventPage.php';
                  $participantParams = $this->_params;
                  $count = 1;
                  $discountRate = 50; //50% discount
                  //get the count of participants
                  foreach ( $participantParams as $participantNum => $participantValue ) {
                     if ( $participantNum && $participantValue != 'skip') {
                        $count++;
                     }         
                  }
                  //if more than one participant for the event then apply the discount
                  if ( $count > 1 && strstr( $this->_values['event']['event_title'], "Insert Your Event Name" ) ) {
                     $v['amount'] = (100-$discountRate)/100*$v['amount'];
                  }                  
                  //modification ends
                        $this->set( 'primaryParticipantAmount',$v['amount'] );
                    } else {
                  //modification starts
                  //special discount for additional participants.
                  require_once 'CRM/Event/BAO/EventPage.php';
                  $participantParams = $this->_params;
                  $count = 1;
                  $discountRate = 50; //50% discount
                  //get the count of participants
                  foreach ( $participantParams as $participantNum => $participantValue ) {
                     if ( $participantNum && $participantValue != 'skip') {
                        $count++;
                     }         
                  }
                  //if more than one participant for the event then apply the discount
                  if ( $count > 1 && strstr( $this->_values['event']['event_title'], "Insert Your Event Name" ) ) {
                     $v['amount'] = (100-$discountRate)/100*$v['amount'];
                  }                  
                  //modification ends
               }
               
                    //modification starts
if ( $count > 1 && strstr( $this->_values['event']['event_title'], "Insert Your Event Name" ) ) {
                  $this->_amount[ ' After '. $discountRate . '% OFF - '. $v['amount_level']. $v['email-5'] ] = $v['amount'];
                  }
               else {
                  $this->_amount[ $v['amount_level'].' - '. $v['email-5'] ] = $v['amount'];
               }
//modification ends

               $this->_totalAmount = $this->_totalAmount + $v['amount'];
                }
            }

Yes. I think it will be good idea. 

Hi Lobo,

Did this went live ever? Seems like didn't from the Jira status.

Thanks
Rohit

Thanks Lobo. As I see from http://issues.civicrm.org/jira/browse/CRM-4182 the issue has a status "In Verification" correct me if I am reading it incorrectly.
Thanks
Rohit

Yes that is present in 2.2.x. We use this hook to implement discounting for events on civicrm.org (just used it today!)

note that implementing a hook requires writing PHP code etc

check: http://civicrm.org/node/566

for more details on the discount hook

lobo

the format is pretty much identical to that of drupal. so 99% of that post applies. a couple of changes

1. put all your code in a file civicrmHooks.php and place that in the civicrm_root directory

2. standalone/joomla can only have one implementation of a hook, the function needs to be prefixed with standalone (or joomla)

so: standalone_civicrm_buildForm( .. )

etc

3. no plans to include it in core in the short term. I suspect it will get into core at some point
