You might use this if the output file??™s contents

var: This optional parameter is used to pass in various other parameters of use to
the inserted template. You can pass along numerous parameters in this fashion.
The name parameter is special in the sense that it designates a namespace of sorts
that is specific to the contents intended to be inserted by the insertion statement.
When the insert tag is encountered, Smarty seeks to invoke a user-defined PHP function
named insert_name(), and will pass any variables included with the insert tag
via the var parameters to that function. Whatever output is returned from this function
will then be output in the place of the insert tag.

Once encountered, Smarty will reference any available user-defined PHP function
named insert_banner() and pass it two parameters, namely height and width.
The literal Statement
The literal statement signals to Smarty that any data embedded within its tags
should be output as is, without interpretation. It??™s most commonly used to embed
JavaScript and CSS (cascading style sheets) into the template without worrying about
clashing with Smarty??™s assigned delimiter (curly brackets by default).
