Only show Element If page has Event in Future

Kirby 3 Solved ✅
1

I have a page with two sections “Upcoming” and “Past”. Events will automatically move to “Past” as soon as they are older than the current date.

Now, I would like to show the headline “Upcoming” only when there is an event with an end date in the future.
I thought about “page->hasChildren()”

Does anyone have an idea?
Thanks!

What you would have to do is check if the $upcoming collection is empty, e.g. assuming your collection with the upcoming event is called $upcoming:

<?php
if ($upcoming->isNotEmpty()) {
  // list the upcoming event
}

If you need more specific help, please post your code.

Thanks @moonwalk,
I am creating the collection after the element which I want to hide. Is it important to create it before the if-statement?

    <div class="content-wrapper">
        <div class="exhi-content"> 
            Upcoming <--- this should be hidden when $upcoming is empty
            <br><br> <--- this should be hidden when $upcoming is empty
            <?php 
            $upcoming = $page
            ->children()
            ->filter(function ($child) {
                return $child->from()->toDate() > time() || $child->to()->toDate() > time();
            })
            ->sortBy(function ($page) {
                return $page->from()->toDate();
              }, 'desc');

            $past = $page
            ->children()
            ->filter(function ($child) {
                return $child->to()->toDate() < time();
            })
            ->sortBy(function ($page) {
                return $page->from()->toDate();
              }, 'desc');
            ?>

            <?php 
            if ($upcoming->count() > 0): ?>
            <ul>
                <?php foreach ($upcoming as $event): ?>
                <li class="event">
                    <time>
                        <?= $event->from()->toDate('j.n') ?> – <?= $event->to()->toDate('j.n.Y') ?> –
                    </time>
                    <?= $event->location()->kti() ?>
                    <br>
                    <?= $event->name()->kti() ?>
                </li>
                <br>
                <?php endforeach ?>
            </ul>
            <?php endif ?>
            <br>
            Past
            <br><br>
            <?php 
            if ($past->count() > 0): ?>
            <ul>
                <?php foreach ($past as $event): ?>
                <li class="event">
                    <time>
                        <?= $event->to()->toDate('Y') ?> –
                    </time>
                    <?= $event->location()->kti() ?>
                    <br>
                    <?= $event->name()->kti() ?>
                </li>
                <br>
                <?php endforeach ?>
            </ul>
            <?php endif ?>

        </div>
    </div>

Yes, ideally you always put your variable definitions at the top of the template (or into a controller), anyway to keep your templates clean (unless you have to define a variable later, eg. in a loop).

Thanks, worked for me!
