Get last three repeater posts to another template

[Roych]

Hello,

I'm new to PW and like it already  I have just created my first site with PW and need some help getting repeater posts from one page to expl. home page.

I have a page called Events with template events.php . Page has a repeater field called Events_repeat. Now I would like to show last three events on a homepage, how do I do that.

I have tried with:

	<?php foreach ( $pages->find('template=events, limit=3') as $event ):?>
		<div class="hovereffect">
			<img src="<?=$event->images->first->url ?>" width="100%" class="img-responsive" style="border: 9px solid white;">	
			<div class="overlay">
				<h2><?= $event->images->description->first ?></h2>
			</div>
		</div>
	<? endforeach; ?>

But it doesn't work, what am I doing wrong. I tried to look on a forum but couldn't find anything helpful really.

Thank you very much

Hi.

In your code you find all pages with template "events", but as I understood you want to show some repeater items from "event@ page

$items = $pages->get("/event/")->events_repeater;

if($items->count()) {
	foreach($items as $items) {}
}

The upper didn't quite work for me was a good starting point found this and it works great but how do I limit it to only 3 last events.

<?php
    $Events = $pages->get('/Events/')->Events_repeat->getArray();
    foreach ($Events as $key => $events) { 
	?>
<div class="col-md-4 wow animated bounceInRight">
	<div class="hovereffect">
		<img src="<?=$events->Event_slika->first->url ?>" width="100%" class="img-responsive" style="border: 9px solid white;">	
			<div class="overlay">
				<h2><?=$events->Event_slika->first->description ?></h2>
			</div>
	</div>
</div>
        
    <?php 
	if ($key == 2) {
        break;}
    };   
?>

Thank you

@Roych Not sure if I'm right here, but have you tried something like:

$Events = $pages->get('/Events/')->Events_repeat->find('limit=3,sort=-created')->getArray();

LimWub,

Your code only shows the first 3. 

Try this: 

$Events = $pages->get('/Events/')->Events_repeat->find('limit=3,start=-3');

Another option:

$Events = $pages->get('/Events/')->Events_repeat->slice(-3);

Works great, only sorting is wrong, it won't show last three.

Thank you

Try using $Events->reverse() in your foreach loop.
