Including entire files of boilerplate in the description can be done in a manner similar to that described in a prior tip called Using Boilerplate Text in the Product Description. However, instead of the keyword being replaced by a string, I'll show you how to replace a keyword with a file.

Create the directory

catalog/includes/languages/<your-language>/boilerplate

You will populate this directory with files whose names are <some-keyword>.html. For instance, suppose you have some text you want to add to all your DVD products. Create a file called DVD.html in this directory, i.e.

catalog/includes/languages/<your-language>/boilerplate/DVD.html

Put whatever HTML marked-up text you want in that file.

Now go to

catalog/product_info.php

Replace

  <p><?php echo stripslashes($product_info['products_description']); ?></p>

with this code:

<?php
function html_include_cb($match) {
      $prefix = "HTML_INCLUDE_";
      $match_filename = str_replace($prefix, '', $match[0]); 
      $filename = DIR_WS_LANGUAGES . $_SESSION['language'] .  
                 '/boilerplate/' . 
                 $match_filename  . ".html";
      $buffer = ""; 
      if (file_exists($filename)) { 
          $handle = @fopen($filename, "r"); 
          while (!feof($handle)) {
              $buffer .= fgets($handle, 4096); 
          }
          fclose($handle);
      }
      return $buffer;
}
$products_description = $product_info['products_description'];
$pattern = "/HTML_INCLUDE_[a-zA-Z0-9]*/"; 
$products_description = preg_replace_callback($pattern, "html_include_cb", 
           $products_description, -1);
echo '<p>' . stripslashes($products_description) . '</p>';
?>

Now to use this logic, all you need to do is enter HTML_INCLUDE_DVD in the product description (under Admin - Categories), and when you display the product info page, it will be changed. For any HTML_INCLUDE_SomeAlphanumericString you add to a product description, simply create a file called

includes/languages/<your-language>/boilerplate/SomeAlphanumericString.html

and it will automatically be displayed. Note that the string really does have to be alphanumeric; don't use dashes, underscores, spaces or special characters in the name.

Although this tip describes the additive use of HTML Boilerplate, it can also be used to completely replace the product description which is entered in the osCommerce Admin Panel.
