PHP Enhancing a Simple PHP Application Adding Search: Controller & View Accounting for Empty Results

accounting-for-empty-results-2 2 of 3 challenge task

If the array is NOT empty, the foreach loop will execute. But if it IS empty, we should display a message. Add an else block to the conditional that displays the following message in an HTML paragraph tag: 'There are no flavor recommendations for you.' May i know what is wrong with my code?

index.php 
<?php

    $recommendations = array();

?><html>
<body>

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

Hello Zweih! I had trouble with this one too. I put your code in the challenge and it seems that when I use less php <?php ?> tags and echo out the HTML like in the example below then it works. Everything else looks great to me. I hope this helps!

<?php

    $recommendations = array();

?><html>
<body>

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

I concur -- I've done PHP for years and have so far been doing these challenges without watching any of the videos. I tried all of the industry standard stuff of !empty, isset && !empty, isset && sizeof($) > 0.. etc..

This is one case, where teamtreehouse is NOT teaching standards...
