readme_on_this_day.txt (this file)

Usage:
------
1) unpack this package in your extensions/snippets/ folder.
2) place a [[on_this_day]] tag in any of your template files (I recommend placing it in frontpage_template.html, just before [[subweblog:standard]]
).
3) rebuild the FrontPage(s).
   
Description:
------------
This tag returns HTML code with text = title and a hyperlink to the entry for entries posted "on this day", up to a user specified maximum number of years ago.


Parameters:
-----------
* @param	string	beginText  - If any entries are found, then this text will be
*                                written to the generated HTML before the entries
*                                (e.g, '<h1>On this day...</h1>'
* @param	string	endText    - If any entries are found, then this text will be
*                                written to the generated HTML after the entries
*                                (e.g, '<HR>')
* @param	string	noMatchText - If no entries are found, then this text will be
*                                written to the generated HTML between beginText
*                                and endText (neither will be written if this
*                                parameter is empty)
*                                (e.g, '<h1>In previous years..</h1>'apparently
*                                nothing interesting happened on this day.'
*                                Pass an empty string '' if you don't want to see
*                                anything
* @param	string	weblog     - This really *should* be specified. If not, or if
*                                passed as '*', the snippet will attempt to use
*                                the current blog, failing that, the first blog
*                                found
* @param	int     maxYears   - Only output entries up to this many
*                                years old.


* History:
*
* v 1.4 2006/05/19  Singapore
*   - fixed to make it work correctly with Pivt 1.30 RC2. It was not generating
*     correct URLs owing to a workaround required for a previous Pivot version
*     which had to be removed for 1.30 (undid v1.3 of the snippet)
*   - added 'version control'
*
* v 1.3 2006/02/21  Sentosa Island, Singapore
*   - work around a known Piovt problem with snippets which call make_filelink()
*
* v 1.2 2006/01/16  Sentosa Island, Singapore 
*   - local variable $db clashed with global variable
*   - change all output '<br>' to '<br />' for W3C validator compliance   
*   - added 'version control'
*
* v 1.1 2005/10/21  London, UK
*   fixed a problem pointed out by Matthias D in another snippet, which was
*   based on this one. If parameter $weblog is '*', we need to use a real
*   weblog when calling some Pivot functions or accessing some Pivot data.
*
* v 1.0 2005/04/18  London, UK
*   initial version
