I wrote a test for this to see how it works against v3 api - passing in role_id resulted in no filtering. Passing in participant_role_id gave error "Illegal offset type"

So, I guess there is definitely something broken.

So, ideally you would upgrade to v3 & debug it....

The errror is somewhere in here  - in the utils.php file

        case 'participant_role':
            $role = CRM_Event_PseudoConstant::participantRole();
            $participantRoles = explode( ",", $value );
            foreach ( $participantRoles as $k => $v ) {
                $v = trim( $v );
                if (  $key == 'participant_role' ) {
                    $participantRoles[$k] = CRM_Utils_Array::key( $v, $role );
                } else {
                    $participantRoles[$k] = $v;
                }
            }
            require_once 'CRM/Core/DAO.php';
            $values['role_id'] = implode( CRM_Core_DAO::VALUE_SEPARATOR, $participantRoles );
            unset( $values[$key] );
            break;


Pasted below is the v3 test.

    /**
     * check get with role id - create 2 registrations with different roles.
     * Test that get without role var returns 2 & with returns one
     */
    function testGetParamsRole()
    {
       $participantRole2 = civicrm_api('Participant', 'Create', array('version' => 3, 'id' => $this->_participantID2, 'role_id' => 2));
       
        $params = array(
                       
                        'version'                     => $this->_apiversion,
                     
                        );
        $result = & civicrm_api3_participant_get($params);
        $this->assertEquals($result['is_error'], 0);
        $this->assertEquals($result['count'], 3);
     
        $params['participant_role_id'] =2;
        $result = & civicrm_api3_participant_get($params);
        $this->assertEquals($result['is_error'], 0, $result['error_message'] . "in line  " . __LINE__);
        $this->assertEquals(2,$result['count'], "in line  " . __LINE__);     
        $this->documentMe($params,$result ,__FUNCTION__,__FILE__);
   }

I also get an illegal offset type if I user participant_role_id.

I'll do my best to debug and report the results here.

try this way:

    require_once "api/v2/Participant.php";
    $params = array(
                    'participant_role_id' => array( 3 => 1 ),
                    );
    $participants =& civicrm_participant_search($params);
    print_r( $participants );


You can also send in a contact_id / other parameters to restrict it further

oops sorry, yes, its an array of

[role_id 1] => 1
[role_id 2] => 1
...

u can send in more than one role id, and it does an OR on them

lobo

THank you! So, this got rid of the error message and works (using participant_role_id and the array structure described).

Now, I have something else very strange going on. I'm using this to customize the options in a custom select list field, in hook_civicrm_customFieldOptions(). When I add a participant_role_id param, it replaces my $options array with a list of active roles after running civicrm_participant_search()! Here is the relevant code so you can see where I'm debugging:


        require_once "api/v2/Participant.php";
        $params = array(
          'contact_id' => $contactID,
          'participant_role_id' => array(6 => 1),
        );
        dsm(print_r($options, true));
        $participants = civicrm_participant_search($params);
        dsm(print_r($options, true));

The output from those two dsm()s is:

Array
(
    [0] => None
)
Array
(
    [1] => Attendee
    [5] => Instructor
    [6] => Student
)
Now, of course I can correct this by just clearing the $options array after calling civicrm_participant_search and building it from scratch, so I don't really need any more help. But I'm very curious how this is happening, and how it's even possible.
