Many Opencart users must be aware of this awful problem of Opencart, you can add a product which is out of stock. But you will not be allowed to checkout, which is completely frustrating to the users/shoppers. Recently i was working on an Opencart site and thought of fixing this problem. I was able to fix it without much sweat.
I am sharing it for all those Opencart users who wants to change the Add to Cart button to Out of Stock, for products which are not available.

Rule of the Thumb: Backup the said file before doing anything, in case anything bad happens.

Fire up your FTP program or your cPanel, and then open the following php file


Please note that the theme name will differ from site to site. For this tutorial, i am using emanipur as the theme name.

After opening that file, find the Add to cart button which is somewhat like this 

<input type="button" value="<?php echo $button_cart; ?>" id="button-cart" class="button cart-product" />

Please note that the button Id and class may be different for your theme. The only thing you need to look out is the $button_cart value.

Now, remove the above lines and change with the following slightly modified code

<?php if ($stock == "In Stock")
               <input type="button" value="<?php echo $button_cart; ?>" id="button-cart" class="button cart-product" />
         <?php }
              <a class="button" style="font-size:16px;">Out of Stock</a>

That's it. Now instead of that Add to Cart button, it will be replaced by Out of Stock button/text.
Please remember that i am using my own button class for the Out of Stock button, you can create or use your own class to suit your theme appearance.
