| 21: | * Smarty plugin |
| 22: | * ------------------------------------------------------------- |
| 23: | * Type: function |
| 24: | * Name: xoops_link |
| 25: | * Version: 1.0 |
| 26: | * Author: Skalpa Keo <skalpa@xoops.org> |
| 27: | * Purpose: format URL for linking to specific Xoops page |
| 28: | * Input: module = module to link to (optional, default to current module) |
| 29: | * page = page to link to (optional, default to current page) |
| 30: | * params = query string parameters (optional, default to empty) |
| 31: | * ex: urlparm1=,urlparm2,urlparm3=val3, etc..... |
| 32: | * urlparm3 value will be set to val3 |
| 33: | * urlparm2 value will keep current one (no = sign) |
| 34: | * urlparm1 value will be set to empty ( = sign, but nothing after) |
| 35: | * |
| 36: | * I.e: The template called by 'index.php?cid=5' calls this function with |
| 37: | * {xoops_link page="viewcat.php" urlvars="cid,orderby=titleA"}> |
| 38: | * Then the generated URL will be: |
| 39: | * XOOPS_URL/modules/MODULENAME/viewcat.php?cid=5&orderby=titleA |
