Populate div on username password error

[mds1256]

I have a div on my webpage that will contain an error message, basically 'username or password incorrect.'

 

At the moment on the login page I have the div containing:

 

<div id="errorMessage"><?php echo $errorMessage; ?></div>

 

and in the php code i have:

 

$errorMessage = "";

if(isset($_POST['username']))
{
      // check if username and password exists
     // else $errorMessage = "username or password incorrect";
}

 

but unfortunately this doesn't seem to show on the page, any ideas?

for one thing, it's commented out...

secondly, you need to do:

if($condition){
     //code
}else{
     //code
}

 

Don't mix using brackets with not using them. Even if you do syntax with no brackets, the code has to be on the next line under the if and else.

sorry the above is not the exact code and it s mixture of pseudo code and php...

Well that's useful. We're not psychics....

I have just decided to store a true / false value in a session variable and use this to decide if the username or password is incorrect.

 

seems to work.
