Question

This question is about Kohana framework. I’m new to it.

Using foreach() I want to display some data. Everything is fine, but I want to group that data 4 items in a row so it looks like:

1st 2nd 3rd 4th
5th 6th 7th 8th
9th 10th 11th 12th
....

That’s why I have to add <div> every 4th time.

How do you make it? Do you use a simple counter and check if its mod is zero? Is there a special Kohana function to check the number of the current $item within foreach() if it is the first, the second or the n-th… item ?

<?foreach ($items as $item): ?>
//add <div> tag for 1st, 4th, 7th, etc item

//do something

//add closing </div> tag for 1st, 4th, 7th, etc item
<? endforeach; ?>

Answer 1

Using the foreach construct specifying the array key via $key => $item, you can test if $key % 4 == 0 (or maybe $key % 4 == 3 in your case) to close the open <div>.

// Initial opening div..
<div>
<?foreach ($items as $key => $item): ?>
 <?=$item ?>
 <? if ($key % 4 == 3): ?>
... Close the open div and open a new one
</div>
<div>
<? endif; ?>
<? endforeach; ?>
</div>

The templating syntax hurts my eyes. Here’s proper PHP:

echo '<div>';
foreach ($items as $key => $item) {
  echo $item;

  if ($key % 4 == 3) {
    echo '</div><div>';
  }
}
echo '</div>';

Given the following input:

$items = array('a','b','c','d','e','f','g','h','i','j','k');
// Output:
<div>abcd</div><div>efgh</div><div>ijk</div>
