Question

Let's make sure that foreach loop executes correctly if the $recommendations array is NOT empty. Add one element to the $recommendations array with a value of 'Avocado Chocolate'.

http://teamtreehouse.com/library/enhancing-a-simple-php-application-2/adding-search-controller-view/accounting-for-empty-results

my code:

<?php
$recommendations = array();
$recommendations[] = 'Avocado Chocolate';

?><html>
<body>
<h1>Flavor Recommendations</h1>
<?php if(!empty($flavors)) { ?>
<ul>
    <?php foreach($recommendations as $flavor) { ?>
        <li><?php echo $flavor;  ?></li>
    <?php } ?>
</ul>
<?php } else { ?>
    <p><?php echo 'There are no flavor recommendations for you.'; ?></p>
<?php } ?>
</body>
</html>

Hello Lyric.

I had a quick look at your code before testing it.

Shouldn't the IF statement refer to $recommendations rather than $flavors? when checking if empty or not? I would simply change that.

Let me know if it works. ;)

Yes vittorio is right, that's the mistake. I don't know why you've changed this value, you have to leave it as you typed it previously and just add the asked value to the array as you did once again at the top of your code.

<?php
$recommendations = array();
$recommendations[]='Avocado Chocolate';
?>
<html>
<body>
<h1>Flavor Recommendations</h1>
<?php if(!empty($recommendations)) { ?>
<ul>
    <?php foreach($recommendations as $flavor) { ?>
        <li><?php echo $flavor;  ?></li>
    <?php } ?>
</ul>
<?php } else { ?>
    <p><?php echo 'There are no flavor recommendations for you.'; ?></p>
<?php } ?>
</body>
</html>
