Pre-ordering

• Went to Administration > Configuration > Stock and set "Allow checkout" to true and "Show 'Sold Out' image in place of 'Add to Cart'" to true in order to allow customers to pre-order out-of-stock products
• Went to Administration > Configuration > Stock and set "Product's status when out of stock" to true in order to prevent a product from being disabled (removed from the catalog) when the last one was ordered
• Opened includes\templates\template_default\templates\tpl_product_info_display.php and commented out the "Reviews button and count" section.
• Opened includes\templates\template_default\templates\tpl_product_info_display.php and looked for the "Product details list" section, and replaced the line

<?php echo (($flag_show_product_info_quantity == 1) ? '<li>' . $products_quantity . TEXT_PRODUCT_QUANTITY . '</li>'  : '') . "\n"; ?>

with

<?php echo (($flag_show_product_info_quantity == 1)
      ? '<li>' . (($products_quantity > 0)
          ? $products_quantity . TEXT_PRODUCT_QUANTITY
          :  'This product is out of stock.' ) .
        '</li>' 
      : '') . "\n"; ?>

This replaces the "0 Units in Stock" message with "This product is out of stock." when the quantity hits 0.

• Opened … and looked for the create_add_products() function, and the following code (not including <?php and ?> tags):

<?php
if ($stock_values->RecordCount() > 0) {
   // do not decrement quantities if products_attributes_filename exists
   if ((DOWNLOAD_ENABLED != 'true') || $stock_values->fields['product_is_always_free_shipping'] == 2 || (!$stock_values->fields['products_attributes_filename']) ) {
      $stock_left = $stock_values->fields['products_quantity'] - $this->products[$i]['qty'];
      $this->products[$i]['stock_reduce'] = $this->products[$i]['qty'];
   } else {
      $stock_left = $stock_values->fields['products_quantity'];
   }
?>

Right after that I inserted (not including <?php and ?> tags):

<?php
   /** Adjust the quantity level if it's under 0 **/
   if ($stock_left < 0) $stock_left = 0;
?>
