CiviCRM Community Forums (archive)

I am on Drupal 6 and CiviCRM 2.1. I have a block that pulls up a bunch of CiviEvents and orders them by date. It's been working fine for quite some time. Today I noticed when I submit certain pages or go to certain pages I get the white screen of death. However, no errors are in my apache logs or drupal logs. And when I do a simple refresh, the page then loads fine.

After about 2 hours of troubleshooting this, I deduced that it is related to my block of CiviEvents. Specifically, it is the call to   

civicrm_initialize(TRUE);

If I remove this line, the problem goes away. As soon as I put it back, it starts happening again. I have no idea why this would be causing a problem so suddenly. Can anyone help? The full code I use is below, but like I said it is specific to the initialize function.

<?php
$dated_events = array();
if (module_exists('civicrm')) {
  civicrm_initialize(TRUE);
  require_once 'api/v2/Event.php';
  
  // This example limits listing to public and active events
  $params = array ('is_public'     => 1, 'is_active'     => 1);
  $myEvents = civicrm_event_search( $params );
  
  if ($myEvents) {
    $count = 0;
    
    // Call the sorting function
    usort($myEvents,'cctv_civicrm_get_start_date');
    foreach ($myEvents as $event) {
      $now = time( );
  // print_r($event);
      // Need to format the event end date in unix time, so we call a CiviCRM helper function
      $endDate = CRM_Utils_Date::unixTime( $event['end_date'] );  
      $startDate = CRM_Utils_Date::unixTime( $event['start_date'] );  

      // We want to show any events whose end dates have not passed
      if ( $now <= $endDate ) { 
        
        // Now we format the event start and end dates again to be user-friendly
        $startdate = date('n/j',strtotime($event['start_date']));
        $enddate = date('n/j',strtotime($event['end_date']));
        
        if($startdate != '1/1' && $enddate != '12/31'){
        // if it's a date range, we need to show both start/end dates; otherwise just show start
        if($startdate != $enddate){
          $finaldate = $startdate." - ".$enddate;
        }
        else{
          $finaldate = $startdate;
        }
      
        $eventid = $event['id'];
        list($title_place, $title_desc) = split(":",$event['title'],2);
     
        array_push($dated_events, array('eventDate'=> $finaldate, 'eventTitle' => $title_place.' '.$title_desc, 'eventPath' => 'civicrm/event/info', 'eventQuery' => 'reset=1&id='.$event['id']));
        
        // Increase the counter so we can know when to stop
        $count++;
        }
        // Once we reach 10 events, stop
        if ($count > 9) break;
      } // End if $now <= $endDate 
    } // End foreach
   
  } 
} // End if CiviCRM exists

?>

The white screen of death and the http 500 error indicates that it is a php error. most likely php is aborting OR you are hitting the memory limit
