I’m using ACF with the Repeater Field Add-On to create price lists on a site. I’ve used the “basic PHP approach” described in the Repeater documentation (http://www.advancedcustomfields.com/resources/field-types/repeater/) to create my price lists. This works well on items that have all three of the sub-fields (product, price, description) (see http://lulusalonsf.com/2013/skin/–it does still need CSS work). But when the products don’t have a description field, the code still displays an empty paragraph for the description (see the extra spacing between items on http://lulusalonsf.com/2013/hair/). I tried using the “get_sub_field within the has_sub_field loop” described in the Repeater documentation but it didn’t work (my PHP knowledge is still new, so this may be the wrong approach altogether.)
Is there a way to fetch and display the description sub-field only when it is not empty?
The “basic PHP approach” I’m using is as follows:
<div class="pricelist"><?php $rows = get_field('price_list');
if($rows)
{
echo '<ul class="leaders">';
foreach($rows as $row)
{
echo '<li><span class="service">' . $row['product_or_service'] . '</span> <span class="price"> ' . $row['price'] .'</span></li>';
echo '<p class="description"> ' . $row['description'] .'</p>';
}
echo '</ul>';
} ?>
</div>
Thanks in advance for your help.

Just check if the field is populated with PHP:
<div class="pricelist"><?php $rows = get_field('price_list');
if($rows)
{
echo '<ul class="leaders">';
foreach($rows as $row)
{
echo '<li><span class="service">' . $row['product_or_service'] . '</span> <span class="price"> ' . $row['price'] .'</span></li>';
if( $row['description']) echo '<p class="description"> ' . $row['description'] .'</p>';
}
echo '</ul>';
} ?>
</div>
How do I check if the field is populated with PHP? I must be missing something–I don’t see any difference between the code I posted and the code in your response.
You’ll need to do a check for $row['description'] before actually echoing the <p> tag – that’s why I placed if( $row['description']) before echo '<p class="description">.... This check will simply make sure that $row['description'] is not empty.
If this doesn’t work for you, PHP can also check for empty values in a number of different ways:
http://php.net/manual/en/function.empty.php
http://php.net/manual/en/function.is-null.php
And there’s a discussion of some implementations over at http://techtalk.virendrachandak.com/php-isset-vs-empty-vs-is_null/ !
Ah, and just for ease of reading: http://diffchecker.com/7za0xnhq 🙂
Thank you so much…I knew I was missing something. Adding the magic if( $row[‘description’]) works beautifully.
