Grab several certain images from array

[clickpass]

I want to split my output of an image array, see my code here:

<div class="row">
  	<?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?>
</div>
<div class="row">
  	<?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?>
</div>
<div class="row">
  	<?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?>
</div>

The number of images is 11, but I only want to add four in a row. Is it possible to grab them, e.g. image 1-4, image 5-8, image 9-12?

modulus as long as it's divisible by four you can achieve that

Great, but I still don't know how to select my images. An example would be very helpful.

To be honest, I have not the slightest idea how a modulus operator can do my task.

You can use array_chunk, or use hook to add similar method to WireArray object.

Take a look at this post

<div class="row">
<?php
$i = 0;
foreach ($page->umf_img as $image) {   
  echo "<div class='one-fourth column refs'><img src='$image->url'></div>";
  if ($i % 4 === 0) {
  echo '</div><div class="row">';
  }
  $i++;
}?>
</div>
