  1. 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?

  2. 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!
