One of our clients wanted to start their website as a catalog/inventory site and move towards enabling the site as a full ecommerce site at a later date. Here is what we did and I thought it would be great to share the simple things we did.
Firstly we disabled the following modules from the backend. Go to Admin > System > Configuration > Advanced
1. Checkout 2. Shipping 3. Review
Then we commented the following lines:
list.phtml <button class=”form-button” onclick=”setLocation(’<?php echo $this→getAddToCartUrl($_product) ?>’)”><span><?php echo $this→__(’Add to Cart’) ?></span></button>
view.phtml <?php echo $this→getChildHtml(’addtocart’) ?>
