Functions and blocks
Besides variables you can also use functions. A function looks exactly like a variable, but without the dollar sign. The following code is for example the function to create a link to the web version of en email:
{webversion}Some functions have an open and a close tag. These block functions are used to modify or mark the text that is encapsulated inside the tags:
{mailonly}
Click <a href="{webversion}">here</a> to view this mail in your browser
{/mailonly}The {mailonly} block is used to mark a piece of code to only be visible in the mail version of the message. Would this template be displayed via the web (because someone clicks on the web version link), the code inside the tags will not be rendered. In the above example we cleverly use the {mailonly} block to hide the web version link if the user already views the mail in his or her browser.
