wviewforwp.php

<?php
/*
Plugin Name: WView for Wordpress
Plugin URI: http://www.alberniweather.ca/
Description: This plugin connects to files generated by the wview weather server software (or other software using supported format and naming conventions) and displays the weather data in wordpress using widgets.


Requirements for pre-1.0 release:
- Latest WView weather server software (http://www.wviewweather.com)

Note: JPGraph Library/Support removed due to License Incompatibility

INSTALL:
1: install the plugin in Wordpress
2: install the included phpparameter.htx (found in the wviewforwp plugin directory) in WView and set to generate and upload to your root web folder
2b: if you are not running wview you can still use this plugin by having your weather software create a delimited text file similar to phpparameter.htx.  Name and value pairs can be omitted but names (before the semi-colon) MUST remain the same.
3: setup the WviewforWP plugin in the "Settings" area of Wordpress
4: add and setup a Widget
5: You're done!
