## Description

Allows display of a interactive chessgame using the [ChessFlash PGN viewer](http://chessflash.com/)
in posts and comments. Most of the settings of the Chessflash can be set either 
through adding parameters to the [pgn] tags or through the options page.

NB ChessFlash PGN viewer has been followed up by KnightVision, this plugin still
uses the older version.

Usage:

 * paste pgn-code between [pgn] [/pgn] tags
 * use of parameters with their default values: [pgn height=350 tabmode=false flipboard
   =false initialply=22]…[/pgn]
 * additional parameters (puzzle, twoboards, boardonly) must first be allowed in
   options page
 * colors and piece characters can be set in options page

## Installation

 1. Upload directory `wp-chessflash` to to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Customize the viewer through the options page in the ‘Settings’ menu in WordPress

## FAQ

  ChessFlash has been replaced with KnightVision. Why doesn’t this plugin use that
newer viewer?

I plan to update to the KnightVision version, but then I will probably use a new
name for the plugin as well.

  Why can’t I see the vieuwer on mobile devices?

The viewer uses Flash, which unfortunately doesn’t work on tablets and mobile phones.

  Why are the chess pieces different from those on [chessflash.com](http://chessflash.
com/chessflash.html)?

I recompiled chessflash.swf with a different piece set for use in [Jin](http://jinchess.com/):
[merida.ead-01.zip](http://ixian.com/chess/jin-piece-sets/). The original piece 
set didn’t match the diagrams I use on the website of my chess club. You can replace
chessflash.swf in the plugin directory with the original version to get the original
pieces.

## Changelog

#### 1.2

 * bug fixes for WordPress 4.0.1

#### 1.1

 * fixed the checkboxes to allow ‘boardonly’ and ‘puzzle’ tags
 * added some text to explain ‘initialply=xx’ option

#### 1.0

 * using Chessflash version 2.16 with Merida piece set
 * new parameter (initalply=xx)to start the player at specific ply number

#### 0.9

 * using Chessflash version 2.13 (now possible to change piece characters);
 * introduced options page to set colors and piece characters and allow extra parameters;
 * added transparency to flash object to avoid dropdown menus falling behind object;
 * known issue: Firefox has problem with transparency -> playback with arrowkeys
   is not OK (one click is 2 plies). This is an known Firefox problem, not yet fixed
   in Firefox 3.5.2.

#### 0.5

 * added possibility to change some of the parameters with attributes in the [pgn]
   opening tag. Eg [pgn height=350 tabmode=false flipboard=false] [/pgn].

#### 0.4

 * resolved the problem of the replacement of ‘…’ by WordPress.

#### 0.3

 * resolved the problem of pgn-files being too big by using a more low-level approach
   at filtering out the pgn-codes. Problem was caused by a memory limit in preg_replace_callback;
 * known issue: wordpress removes … and replaces this with something else. The chesscode
   works anyway.

#### 0.2

 * encoding of the pgn-data now in plugin, so you can paste in normal pgn-data between
   the tags;
 * bug: does not work with larger pgn-data, not caused by Chessflash.swf -> has 
   to do something with the way the pgn-data is filtered from the content.

#### 0.1

 * reworked code from plugin show-fen a bit to find the pgn-code in between [pgn][/
   pgn] tags;
 * seems to work with using ChessFlash.swf locally and pasting encoded pgn-data (
   from http://chessflash.com/chessflash.html).
