Easy PHP category help

So in Magento they use php to dynamically call the product categories in the left menu. However, some categories are empty as of right now and I want to use code pull the category count and only display categories with product in them, but if product is added later, the code will allow the category to be displayed. It should be easy but I am not a php coder. I have pasted the code which calls the categories and an article that explains how to this knowing the category ids, but i want it to be dynamic. Any help would be greatly appreciated!

                    <li>
                        <a href="<?php echo $this->getCategoryUrl($_category) ?>"<?php if ($this->isCategoryActive($_category)): ?> class="current"<?php endif; ?>><?php echo $this->htmlEscape($_category->getName()) ?></a> (<?php echo $_category->getProductCount() ?>)
                    </li>
                    <?php endif; ?>
                <?php endforeach ?>

            </dd>
        </dl>
    </div>
</div>
<?php endif; ?>

PHP:

 

Replace:

 <?php if($_category->getIsActive()): ?>

PHP:

with this:

 <?php if($_category->getIsActive() && $_category->getProductCount() > 0): ?>

PHP:

And now it should only render categories which have products in it.

 

dont you have to do something with the if statement to say if count > 0 to display it?

 

nevermind i see that now

 

thanks so much! it worked!

 

tags and wrapper tags are very easy and very useful in php
