Multiple date fields in 1 markdown file?

How can I use multiple date fields in 1 markdown file?

I would like to build an event section to a website. Each event has a start-date and an end-date. I can easily add those fields as such:

startdate: 04/20/2016
enddate: 04/23/2016

But then I seem to be unable to use the filterby and sortby function on the collection ?? It seems like it doesn’t filter/sort at all…

$events = $pages->find("events")->children()->sortBy("startdate", "asc");
$events = $pages->find("events")->children()->filterby("enddate", '>=', time());

I did a quick test with renaming the field to “date”, and then it seems to be working? Is it somehow “hardcoded” that date fields should be named “date”?

What am I doing wrong?


For the filter function, you can use a filter with callback like this:

$events = $pages->find('events')->children()->filter(function($child) {
      return strtotime($child->enddate()) >= time();

As for the sorting bit, that should work without any problems even if the date field has another name.

Have you entered the dates via the panel? I think the format should be yyyy-mm-dd.

And when printing the dates in the template, you can use this code:

echo $page->date('Y-m-d', 'startdate');

where the first param is the date format and the second one is the field name to use.
This is some kind of helper for printing date values.

Thank you both @texnixe & @lukasbestle, your callback tip worked like a charm, and I upon a quick test I think the sorting should be fixed too now upon changing the format to yyy-mm-dd.

You guys make kirby great. This kind of support on a weekday at 10.30pm is simply outstanding.
