I found this code somewhere, that can execute Python scripts from PHP.
I've installed apache2 on the Pi and I'm able to access the PHP script. But when I press the HTML buttons, nothing happens! :(
When I execute the python script via SSH, it works.. so theres nothing wrong with the python scripts I think.
I'm using WebIOPi to monitor the status of the GPIO pins.
Whats the mistake?
PS: I know that this may not be a very safe approach to control the GPIO. I just wanna give it a try though :)
TIA.
