Would it be easier to give you a link to the files in Dropbox? That way you can have all of the associated files. Here is the link:
There are 2 folders- the on titled "Working webpage for Arduino" is the one I am currently using to control my Arduino. The folder titled "New Checkbox PHP" is the one I started for the speaker matrix. The page for the Arduino only has to send a simple command to the serial port (connected to the Arduino) to turn speakers on or off. The checkbox page is the one I am stuck on. I have googled like crazy, but cant seem to put all the pieces together. If there is a better way to do this (the webpage design as well as the CGI script), please let me know. Maybe there is a better way than using a CGI script? I am a good automation guy, but the web interface design is somewhat new to me. The checkboxes seemed to be the only way I could get this to function. It would really be sweet if I could have nice buttons like the Arduino page to select an input and output, but right now I would be thrilled with getting the multiple user inputs into one serial command. Thanks so much for the help!!!
