Good, I would like to obtain data in the same php page, in a login, the problem is that when I enter the values in my login, I save them by POST, but it seems that it always saves me NULL.
.boxlogin{
border-radius:4px;
box-shadow: 2px 2px #d6d6d6;
margin: 75px auto;
width: 320px;
-webki-border-radius:4px;
-moz-border-radius:4px;
}
.btn{
margin-top: 14px;
} <html lang="en">
