The login page submits the form to action="__APP__/Index/login_do ",and then I write the login_do function in the indexing class:

Common function login_do ()

{

if($_SESSION['verify']！ = md5($_POST['userauthcode']))

{

$ this-& gt； Error ("Wrong verification code!" );

}

$ username = $ _ POST[' username ']；

$ password = $ _ POST[' password ']；

$ password = MD5($ password)；

$ user = M(' user ')；

$ RES = $ user-& gt； Where ("user's www.hbbz08.com name =' $ username' & password =' $ password'")->; find()；

Intermediate frequency (resolution)

{

Redirect ('.. /Home/home', 1, "< div align = \" center \ "style = \" padding:100px \ "> & ltfont color = \ "red \"> login succeeded! This page is jumping. ...

}

other

{

$ this-& gt； Error ('Login failed!' );

}

}

The following is the HomeAction class:

Class HomeAction extended operation

{

Common function home ()

{

$ this-& gt； Display ();

}

}
