Adding a Smarty function too easely manipulate the URL query.
Adding a Smarty function too easely manipulate the URL query.

Syntax : {query var1="value1,value2,..." var2="v1,v2,..." var3=NULL}

The function will rewrite the query string by cycling through the different
values, or unset the variable if the value is NULL.

For example :
 {query sort="theme_asc,theme_desc}
 will rewrite the URI variable sort this way :
  theme_asc then theme_desc then theme_desc and so on

{query sort="NULL"}
  will unset the URI variable
