* Smarty plugin
* -------------------------------------------------------------
* Type: function
* Name: xoops_link
* Version: 1.0
* Author: Skalpa Keo <skalpa@xoops.org>
* Purpose: format URL for linking to specific Xoops page
* Input: module = module to link to (optional, default to current module)
* page = page to link to (optional, default to current page)
* params = query string parameters (optional, default to empty)
* ex: urlparm1=,urlparm2,urlparm3=val3, etc.....
* urlparm3 value will be set to val3
* urlparm2 value will keep current one (no = sign)
* urlparm1 value will be set to empty ( = sign, but nothing after)
*
* I.e: The template called by 'index.php?cid=5' calls this function with
* {xoops_link page="viewcat.php" urlvars="cid,orderby=titleA"}>
* Then the generated URL will be:
* XOOPS_URL/modules/MODULENAME/viewcat.php?cid=5&orderby=titleA
* -------------------------------------------------------------
