◆ $template

◆ $touchedBlocks

array HTML_Template_IT::$touchedBlocks = array()

List of blocks to preverse even if they are "empty".

This is something special. Sometimes you have blocks that should be preserved although they are empty (no placeholder replaced). Think of a shopping basket. If it's empty you have to drop a message to the user. If it's filled you have to show the contents of the shopping baseket. Now where do you place the message that the basket is empty? It's no good idea to place it in you applications as customers tend to like unecessary minor text changes. Having another template file for an empty basket means that it's very likely that one fine day the filled and empty basket templates have different layout. I decided to introduce blocks that to not contain any placeholder but only text such as the message "Your shopping basked is empty".

Now if there is no replacement done in such a block the block will be recognized as "empty" and by default ($removeEmptyBlocks = true) be stripped off. To avoid thisyou can now call touchBlock() to avoid this.

The array $touchedBlocks stores a list of touched block which must not be removed even if they are empty.
