redirect user based upon from entry

redirect if field is blank

[flying monkey]

is there a way to rediect a user to the log in screen if he/she has left the user name field blank?

[jatar_k]

if ($_POST['username'] == "") header("Location: login.php");

assuming the username was posted to your script froma form and the text field was named username, this would send them back to a script named login.php located in the same directory.

You could always just reinclude the login form on error as well.

Shouldn't it be:

if ($_POST['username'] == "") header("Location: login.php");

[jatar_k]

thanks Birdman I seem to have left that out

[flying monkey]

well thats what i have right now and it does not seem to work

As jatar said just include the form again if an error occurs, i.e. if the password isnt set:

if($field[user]!=$nuser or $field[pass]!=$npass or $field[email]!=$nemail)
{
echo"<h2 id=\"loginhead\">Please login to continue:</h2>\n";
echo"<h3 id=\"loginhead\">Wrong login details, please try again:</h3>\n";
echo login_form();
}

Thats a snippet of my login area for something, the vars are checked from a database (the user inputs on the form) so you would have to modify it to your needs.

Hope that helps to some extent.... just hope i get a reply to my post.

When you say it doesn't work, do you mean it does not redirect or that you are getting an error?

I suppose you could be using an older version of PHP, which would require using $HTTP_POST_VARS['username'] instead of $_POST['username'].

You're welcome jatar_k, I don't like second guesing the mod ;)

[flying monkey]

no i am using the newest version of php. it just not redirect thats all

Ya figure it out yet?

Seems to me you're going to have to break it down to locate the problem. You should simply put header("Location: login.php") to see if that works by itself. If it does then the problems with the $_POST['username'] variable. Echo it to see what you get.
