Display Username after login

Arcadia · March 8, 2015

Hi everyone i'm having a problem with my login system and really hope someone can help me out here..

I made a login page and it's all working and it perfectly connect to my database but I also want the option when someone logins that they see a welcome message on each page on the website like "Welcome, $username"

I searched on google but each time i pumb into errors

I would like to show the "welcome message" in the header.

Below you can see my code:

Home.php

    center:new google.maps.LatLng(51.508742,-0.120850),
    zoom:5,
    mapTypeId:google.maps.MapTypeId.ROADMAP
  };
  var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

If I see this right, you're not starting a session until the user gets to Login_successful.php, which comes after the user logs in on Inlog.php, where you're trying to set $_SESSION variables

$_SESSION['myusername']= "myusername";
$_SESSION['mypassword']= "mypassword";
header("Location: Login_success.php");

You have to start your session on the Inlog.php (if not sooner) to be able to set your SESSION variables. I.E. - start_session() has to be called before you can set $_SESSION['variables'].

Also, your header has them being directed to Login_success.php, yet the page you gave us in called Login_successful.php. Change that, start your session on the login page so that your $_SESSION vars carry from one page to the next. Also, as you move from one page to the next, be sure to set those $_SESSION vars:

SomePageAfterInlog.php

$myun = $_SESSION['myusername'];
$mypw = $_SESSION['mypassword'];

Then use those variables ($myun AND $mypw) on that page. And on any pages the user goes after logging in, be sure to set your $_SESSION vars like I just showed you. Every page you want to use them has to have them.
