Limiting a foreach loop to the first array

Question

here is my code:

<?php
         foreach ($productsRecord['images'] as $upload):?>
          <?php if ($upload['hasThumbnail']): ?>
            <a href="<?php echo $upload['urlPath'] ?>" rel="lightbox" class="imgborder" title="<?php echo $productsRecord['name'] ?>"><img src="<?php echo $upload['urlPath'] ?>"  alt="" /></a><br />



          <?php endif ?>
        <?php endforeach ?>

How would I go about limiting the results to only the first result, would I use a break; statement?

Cheers

Can you elaborate it a bit more? Do you want just the first element of $productsRecord['images'] ? — Broncha

then just use the first element of the array directly.. Why do you even need to loop for just one element? — Broncha

Try to use current()

your code shall like that:

<?php reset($productsRecord['images']); ?>
<?php $upload = current($productsRecord['images']);?>
<?php if ($upload['hasThumbnail']): ?>
    <a href="<?php echo $upload['urlPath'] ?>" rel="lightbox" class="imgborder" title="<?php echo $productsRecord['name'] ?>"><img src="<?php echo $upload['urlPath'] ?>"  alt="" /></a><br />
<?php endif ?>

To more information about the current() check the manual: http://php.net/manual/en/function.current.php

Or if you want to be absolutely sure that you get the first element, use reset instead of current

Just use the first element of the array directly

$productsRecord['images'][0]

No need to loop here.

Just as a hint: On SO, you will want to indent code with four spaces so it is properly highlighted. If you want to include a variable or function name (or something else) within regular text, you can use inline highlighting by surrounding the code with backticks (`).

Also, as a good practice, you should always check if an index in an array exists before retrieving it. That way you avoid nasty undefined index warnings.

    <?php break; endforeach; ?>
