I have this list page displaying only the 10 latest "articles"

http://65.99.232.147/articles/articles.php

What I need to do is to get the sub navigation also only display the last 10 articles as well.

How to do this? Here is my article nav code:

<li> <a href="/articles/articles.php">Articles</a> <ul>
<?php
list($categoryRecords, $selectedCategory) = getCategories(array(
'tableName' => 'articles',
'selectedCategoryNum' => '', // defaults to getNumberFromEndOfUrl()
'categoryFormat' => 'showall', // showall, onelevel, twolevel
));
?>
<?php foreach ($categoryRecords as $categoryRecord): ?>
<?php if ($categoryRecord['url']) { $categoryRecord['_link'] = $categoryRecord['url']; } ?>


<?php echo $categoryRecord['_listItemStart'] ?>
<a href="<?php echo $categoryRecord['_link'] ?>"><?php echo $categoryRecord['name'] ?></a>
<?php echo $categoryRecord['_listItemEnd'] ?>
<?php endforeach; ?>


</ul>
</li>
<!-- <li><span class="qmdivider qmdividery" ></span></li>-->

On this page: http://65.99.232.147/articles/articles.php you will see the "Articles" link and subnavigation. Right now I only have 4 articles in there, but over time many articles will build up. What I need to do is to only allow the first 10 to appear as a sub nav link to the detail page.

This way if they place 100 articles in there will not be 100 subnav links.

Hi drewh01,

If you add these two lines in red, your foreach will stop after displaying ten records:

<?php $count = 0; ?>
<?php foreach ($categoryRecords as $categoryRecord): ?>
<?php $count++; if ($count > 10) { break; } ?>
<?php if ($categoryRecord['url']) { $categoryRecord['_link'] = $categoryRecord['url']; } ?>
<?php echo $categoryRecord['_listItemStart'] ?>
<a href="<?php echo $categoryRecord['_link'] ?>"><?php echo $categoryRecord['name'] ?></a>
<?php echo $categoryRecord['_listItemEnd'] ?>
<?php endforeach; ?>

I hope this helps! Please let me know if you have any questions.
All the best,
Chris
