Resource Status

[aj]

I would like to create a function that will return the number of current participants and the max_participants for a reservation.
I would like to use the function in the schedule to append to the title like so "Volunteer Group Alpha (4/25)".  This would indicate that there are 4 current participants and a max of 25 for that resource.  I would like to provide that status in multiple locations thats why I am looking at a function.

I have tried to do it this way but it does not seem to return valid info:

function get_capacity($resid) {
   $res = new Reservation($resid);
   $resource = new Resource();
   $max_participants = $resource->get_property('max_participants', $res->get_machid());
   $user_info = $res->users;   
   $total_users = 0;           
   if ($max_participants != '') {
      echo '<div ">' . translate('Participants', array($max_participants)) . '</div>';
   }
   else if ($max_participants != '') {
      // Show how many openings are taken
      for ($i = 0; $i < count($user_info); $i++) {
         if ($user_info[$i]['invited'] != 1 && $user_info[$i]['owner'] != 1) {
            $total_users++;
         }
      }
      echo "<div">$total_users/$max_participants " . translate('Participants') . '</div>';
   }
   
}


Any help would be apprciated...

You're almost there.  You'll need to pass the resourceId in to the Resource constructor.  You can get this off of the reservation object that you loaded up.

Sitll stuck...  Here is what I tried...
I added the funtion to the Schedule.class.php and the call to schedule.template.php in function write_reservation() but it displays the header for the schedule and gets to the first reservation and hangs right after the first line of get_capacity().  Its like it did not finsh the reservation constructor and lost it.
Below is the function....

    function get_capacity($resid) {
       $curr_reservation = new Reservation($resid);
       $curr_resource = new Resource($curr_reservation->get_machid());
       $max_participants = $curr_resource->get_property('max_participants', $curr_reservation->get_machid());
       $user_info = $curr_reservation->users;
       $total_users = 0;           
       if ($max_participants != '') {
          // Show how many openings are taken
          for ($i = 0; $i < count($user_info); $i++) {
             if ($user_info[$i]['invited'] != 1 && $user_info[$i]['owner'] != 1) {
                $total_users++;
             }
          }
       }
       return "<div>" . $total_users . "/" . $max_participants  . " Participants</div>";
    }

Thanks for your help.

You may need to alter Schedule.class.php to include Reservation.class.php.  Are you seeing any error details in the server log files?

[aj]

Including "include_once($basedir . '/lib/Reservation.class.php');" in Schedule.class.php worked perfectly....

Thanks,

Hi AJ,
Would you mind posting your step-by-step modifications for this?

Thank you,

Here you go...

I included the below function in Schedule.template.php

Code:

     /**                                                                       
     * Gets the capacity of a resources for the reservation
     * @param array $resid reservation id
     */                                                                         
     function get_capacity($resid) {
       $curr_reservation = new Reservation($resid);
       $curr_resource = new Resource($curr_reservation->get_machid());
       $max_participants = $curr_resource->get_property('max_participants', $curr_reservation->get_machid());
       $user_info = $curr_reservation->users;
       $total_users = 0;           
       if ($max_participants != '') {
          // Show how many openings are taken
          for ($i = 0; $i < count($user_info); $i++) {
              //if ($user_info[$i]['invited'] != 1 && $user_info[$i]['owner'] != 1) {
                 $total_users++;
             //}
          }
       }
       if ($total_users > $max_participants) {
           return "<font color=red> (" . $total_users . "/" . $max_participants  . ")</font>";
       } else {
                return " (" . $total_users . "/" . $max_participants  . ")";
       }
     }

Then I modified "function write_reservation" in Schedule.template .php:

...

Code:

    $slots = get_capacity($resid);
    $summary_text = $summary->toScheduleCell();   

$cellSummary = '';
if ($summary_text != $summary->EMPTY_SUMMARY)
{   
   $summary_text .= $slots;
   $cellSummary = "<div class=\"inlineSummary\">$summary_text</div>";
   
}

And then Nicks suggestion to add: include_once($basedir . '/lib/Reservation.class.php');  in Schedule.class.php.


This modification will display the open slots vs the max participants for the reservation.
