elvisniperx, after the if statement, instead of using echo, change it to, header(“Location:memberpage.php”);

nice tutorial my good man. well it works perfectly for me the only problem now is how can i put designs on this code? when i’m writting an html code the echo and die doesn’t work anymore. does this tutorial have to be set at a blank page only? ;<

please help me when i used the $_session['username']; it always shows an error. the error is like this: undefined index: username. PLS..HOW CAN I FIX THIS?..

Just a security note: People can manually change their cookies, so storing just a username and checking that isn’t safe. Store the password hash as well and check it against the DB entry.

@TheFoit im not sure if this works but go to line 57 and look for the } and delete it. or theres a missing { somewhere. Hoped it helped =D

can you please put up the code around the 55-60 line area. From the look of the error it looks like you have maybe one to many “}”, or not enough.
Comment by senos64 on February 14, 2010 at 12:07 pm

not sure if this is a smart solution, but it would work I think:

if ($_SESSION['username'])
{ echo “Text for Users”;}
else
{ include ‘index.php’; }

If you are not sure what include does, just google it. It basically checks for whatever is in index.php and puts it in the spot where the include is called for.

Parse error: syntax error, unexpected ‘}’ in /home/a9490936/public_html/JsiteTest/myPHP/phpRegistration/login.php on line 57

how can i make,that a welcome message is shown,when im logged in and the log in form when im logged out?
so it doesn’t work:
session_start();
if ($_SESSION['username'])
{ echo “Text for Users”;}
else
{ echo ” Login-Form “;}

if i remove the session_Start it’s always showing the form.

i did all your tutorials but whenever i log in, there is no text appearing like “You’re in”
or “The user doesn’t exist”..there is only a blank document appeared.. why??
Comment by MuhahaSP on February 14, 2010 at 6:45 pm

I tested this and I had an error.
My database contained a user:
ID:1
Username: Thomas
Pass: 123

-> When I tried loging in it wouldn’t work because of my uppercase “T”

How do you make it check for my name but not error for the uppercase letter?
