I am trying to do this by setting a variable and then using an if statment. However it just doesnt seem to run bin looking at it for hours. Sorry for being a Noob

Code: Select all

<?php


$loginface="<h4>Register<h4/>
			<form action='home.php' method='post'>
			Username: <input type='text' name='username'><br>
			Password: <input type='password' name='password'><br>
			<input type='submit' value='Log In'>
			</form>
			</div>
			<a href='index.php?$logout=true'>";

$logout;			
//$logoutface="<br/><a href='index.php?$logout=1'>Logout</a>";
$logoutface="<form method=post action='index.php?$logout=1'>
<input type='submit' name='logout>
</form>";


if ($_SESSION['username'])
		{
		print "Hello ";
		echo  $_SESSION['username'];
		print "$logoutface";
		
		
		}
	else 
	print "$loginface";		

if ($logout=='1')
	{
  session_destroy();
  $logout="0";
  }
	

	

	?>

I don't fully understand your code or what you're trying to do, but what you're doing there doesn't work in at least one way. You can't do this:

Code: Select all

<a href='index.php?$logout=true'>";
And then access the variable with just $logout. You have to do it like this:

Code: Select all

<a href='index.php?logout=true'>";
And access that value with $_GET['logout'].

Thanx for that I am nearly there. It logs out but I have to press logout twice?

Code: Select all

<?php


$loginface="<h4>Register<h4/>
			<form action='home.php' method='post'>
			Username: <input type='text' name='username'><br>
			Password: <input type='password' name='password'><br>
			<input type='submit' value='Log In'>
			</form>
			</div>
			<a href='index.php?$logout=true'>";

$logout;			
//$logoutface="<br/><a href='index.php?$logout=1'>Logout</a>";
$logoutface="<form method=post action='index.php?logout=true'>
<input type='submit' value='logout'>
</form>";


if ($_SESSION['username'])
		{
		print "Hello ";
		echo  $_SESSION['username'];
		print "$logoutface";
		
		
		}
	else 
	print "$loginface";		

if ($_GET['logout']==true)
	{
  session_destroy();
  $_GET['logout']=false;
  }
	

	

	?>

[text]<a href='index.php?$logout=true'>[/text]
Change it to this
[text]<a href='index.php?logout=true'>[/text]

When you click "logout", what do you see in the URL? Please paste it here. Also, this part:

Code: Select all

print "$logoutface";
Fix both instances of those to this:

Code: Select all

print $logoutface;

Code: Select all

if ($_GET['logout']==true)
Instead of that, use this:

Code: Select all

if (isset($_GET['logout']))
