/*
 * 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
 * -------------------------------------------------------------
