If I look at the schedule for a 4 day event, with an spearate schedule for each day

the links at the top of the page seem to be alphabetically ordered instead of chronilogical.

Please can you let me know how to list the days in chronilogical order?

Hi Ben,

I responded to a similar question about this for The Explorer App in an email, and since sending it, I've thought of a more elegant way. In the functions.php file for your theme (or any customization plugin you might have going), add the following:

function my_sorter($a,$b){
 if($a == "Update Day"){
 return -1;
 }
 elseif($b == "Update Day"){
 return 1;
 }
 elseif ($a == "Allied Professionals"){
 return 1;
 }
 elseif($b == "Allied Professionals"){
 return -1;
 }
 else{
 return strcmp($a,$b);
 }
}

add_filter('Smarty_Instance_resource_name','my_Smarty_resource_name',12,2);
function my_Smarty_resource_name($resource_name,$args){
 $smarty = $args[0];
 switch($resource_name){
 case 'festivalapp.schedule.tpl':
 case 'ifestivalapp.table.tpl':
 $parm = ($resource_name == 'festivalapp.schedule.tpl' ? 'ScheduleNames' : 'Schedules');
 $ScheduleNames = $smarty->get_template_vars($parm);
 uasort($ScheduleNames,'my_sorter');
 $smarty->assign($parm,$ScheduleNames);
 break;
 }
 return $resource_name;
}

Basically what you're doing here is hooking into the piece of the code that displays the smarty template. If you're displaying either festivalapp.schedule.tpl (the template for the schedules page) or ifestivalapp.table.tpl (the template for the Explorer App), then you're going to resort (using the function uasort) the Schedule Names).

I think that's the best way to approach sorting schedule names by something other than alphabetical order.

Cheers
Trevor
