[Resolved] cant figure it out

[slimjim]

I am trying to figure this out but can't. I want to be able to take $username and echo it in Here :
print "logged in ( I want $username Here ) successfully<br>";

But everything i try i get errors.

<?
require_once "db.php";
if (isset($submit)) // name of submit button
{ $query = "select * from admin where username='$username' and password='$password'"; 
$result = mysql_query($query) ; 
$isAuth = false; //set to false originally
while($row = mysql_fetch_array($result))
{
if($row['username'] === $username) 
//above row checks to see if username/password combination exists 

{ 
$isAuth = true; 
session_start();
session_register('username');
} 
} 
if($isAuth)
{

print "logged in successfully<br>";
print "<A href='admin.php'>Go to Admin Panel</a>";
}
else
//if login/pass does not exist 
{
print "Wrong username or password";
}
}
?>

What errors do you get?

[slimjim]

With the existing code shown i get no errors. But when I try to add <? echo $_SESSION['username'] ?> in that place i mentioned. I get an error.
Which tells me I am either missing something or something isnt right somewhere.

Below is the error i get when i try to use that echo
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/var/www/html/test/admin/authenticate.php on line 21

You just need to break things up a bit........

print "logged in " . $_SESSION['username'] . " successfully<br>";

PHP doesn't do well with arrays inside of the double quotes.

Tired that too and I still get nothing showing up. I get no error, but I also do not get the username showing up.
Is my sessions even right ? Or what

Thank You

Try setting the session variable after you register it.

session_start();
session_register('username');
$username = $row['username'];

your missing your semicolon at the end of the echo statement

echo $_SESSION['username']; ?>

but besides that, you can display the session vars on the same script that registered them. they are only available on subsequent pages.

Great that did it. Thanks a Bunch !!

I had a feeling it was something wrong with the sessions, but couldnt figure it out.

Thank You 😃

not true. put the array in {}

print "logged in {$_SESSION['username']} successfully<br>";

don't use session_register at all. It is a security risk because it makes your vars global.

assign session values like this:

$_SESSION['username'] = $row['username'];

So should i do this then ?

session_start(); 
$_SESSION['username'] = $row['username'];
//$username = $row['username'];
