Hello,

I have a portfolio page where there are 3 posts listed across the screen. the third one on each row has no right margin.

So effectively the 3rd, 6th, 9th etc post has no right margin.

How can I create a list with 'foreach' but it display a different one every third?

so, for the first and second in each row:

<?php foreach ($blogRecords as $record): ?>
<div class="box left">
<img src="<?php echo $record['list_image_url'] ?>" alt="<?php echo $record['list_image_desc'] ?>" />
<h2><?php echo $record['title'] ?></h2>
<p><?php echo $record['list_image_descs_t'] ?></p>
</div>
<?php endforeach ?>

Then every third remove the class 'left' from the div:

<?php foreach ($blogRecords as $record): ?>
<div class="box">
<img src="<?php echo $record['list_image_url'] ?>" alt="<?php echo $record['list_image_desc'] ?>" />
<h2><?php echo $record['title'] ?></h2>
<p><?php echo $record['list_image_descs_t'] ?></p>
</div>
<?php endforeach ?>

Any ideas?

Thanks Jono

Hi Jono,

One thing you could try would be to have a counter variable that counts off each 3 records, and outputs a different div tag on the third.

Try this code:

<?php $count=1;?>

<?php foreach ($blogRecords as $record): ?>
<?php if($count!=3): ?>
<div class="box left">
<?php else: ?>
<div class="box">
<?php $count=0;?>
<?php endif ?>
<img src="<?php echo $record['list_image_url'] ?>" alt="<?php echo $record['list_image_desc'] ?>" />
<h2><?php echo $record['title'] ?></h2>
<p><?php echo $record['list_image_descs_t'] ?></p>
</div>


<?php $count++; ?>
<?php endforeach ?>

Hope this helps
