Installation method

Widgets can be installed on PageFlakes using a simple link.

UPDATE: There is currently a bug on PageFlakes which triggers an error message when using the install link. We have posted a message in their forum.

The URL can be built programatically as follows:

http://www.pageflakes.com/AddFlake.aspx?URL=www.widgetavenue.com/wdg/loaders/pgf.php%3F[Encoded list of args]

For example,using the Hello World widget built here, if your source HTML file is located at http://myserver.com/HelloWorld.html, you will be able to install your widget on iGoogle using the following link:

http://www.pageflakes.com/AddFlake.aspx?URL=www.widgetavenue.com/wdg/loaders/pgf.php%3Froot%3Dhtml%26url%3Dhttp%253A%252F%252Fmyserver.com%252FHelloWorld.html

If your URL is correct, you should get something similar to this.
