The general principle is you cannot use echo
before header()
. So, this will never work:
echo "this is my header";
header("Location: account.php");
echo "this is my footer";
However, if you sent the headers first, everything works fine:
header("Location: account.php");
echo "this is my header";
echo "this is my footer";
In your case, you should do the check before you include the header:
require_once('models/init.php'); // db connection and other functions
if ($user_is_logged_in) { // Do your check here
header("Location: account.php");
}
include('header.php'); // some html code for the header, with one line php-function to check if user is logged in, if so show "home" tab instead of "login"
echo "<form>" // display the login form
include("footer"); // including footer, some html/js code.
