Generate a QR image with URL parameters

Question

I'm in need of generating a QR image - but the URL needs to include parameters.

I've tried Googles:

http://chart.apis.google.com/chart?cht=qr&chs=300x300&chl=http://www.me.com/me.asp?i=1&n=2

...but the image generated, only links to:

http://chart.apis.google.com/chart?cht=qr&chs=300x300&chl=http://www.me.com/me.asp?i=1

I.e. Without n=2 at the end.

Does anyone know how to generate a QR image, which will allow more than one parameter?

Answer 1

You have to url encode the ampersand character & , which is %26 encoded, so it gets not confused with the normal & ampersand character used to separate the variables in your google url, so use this:
