I configured my Raspberry Pi as a LAMP server.
I have LEDs connected to my RP and can control them with c/c++ programs.
Now I want to built a web interface to control the colors of my LEDs.
For my first attempt I used JQuery to send different commands to a PHP script that would execute a program with the color as a parameter.
This doesn't seems to be the best solution, because I'm pretty limited on any effects I can make.
So my second idea was to use sockets to send information to my program.
This means my ledControler program listens for incoming commands and executes them.
For this I used Websockets, but since I didn't use a library for my c++ program, it was very painfull to implement the whole WebSocket RFC.
Another idea was to use PHP sockets. But I didn't test it out.
My question is, am doing this completely wrong? Is there a simpler preferred way to do this?

Hello Forum!
I have a little problem. What I have is a registration page.
I want to validate the input of the user in real time.
I use JQuery.
$("#inputUsername").change(checkUsername); $("#inputEmail").change(checkEmail); $("#inputPassword").change(checkPassword); $("#inputPasswordConfirm").change(checkPasswordConfirm);
I check if something was changed.
For example like this:
function checkUsername() { $(this).popover({placement:"right", container:'body'}); var username = $(this).val(); if(username == '') { $(this).data('bs.popover').options.content = 'Please enter a username'; $(this).popover("show"); } else if(username.length < 5 || username.length > 20) { $(this).data('bs.popover').options.content = 'Please enter a username with 5-20 characters'; $(this).popover("show"); } else { $(this).popover("destroy"); } }
Now when the user submits the form, I thought I could use something like this:
$("#registerForm").submit(function( event ) { if(!checkUsername || !checkEmail || !checkPassword || !checkPasswordConfirm) { event.preventDefault(); } });
Obviously the functions don't have return types. But even with it doesn't work.
With it doesn't work I mean that submit event isn't ignored even if there are errors in the form.
I might be doing something wrong with JavaScript as I'm not used to it!
Before someone suggests a plugin, I don't have enough control with them.
Thanks!

Okay that's an idea. But this question is not Raspberry Pi specific, as it would fit any other server.
