And when i want to use some variable that is out of the function it doesent
work.. WHY? and how could i make it work..

Example is bellow... i wont to use $username in functio logedin() but that
doesent seems to work..

CODE: (problem is marked with comment)

<?php
if(!isset($_SES SION['login'])){
if(isset($_POST['username']) && (isset($_POST['password'])))
{
if (empty($usernam e) || empty($password )){
echo "<p><p>";
echo "<script>alert( 'Niste unjeli korisnièko ime ili zaporku')</script>";
echo "<div align='center'> <a href='login_lin k.php'>Poku¹ajt e
ponovo</a></div>";
echo "<p>";
echo "<div align='center'> Ako ste zaboravili zaporku mo¾ete je saznati <a
href='zaboravlj ena_zaporka_lin k.php'>ovdje</a>";
exit;
}
user_login();
}elseif(isset($ _REQUEST['logout']))
{
unset($_SESSION['login']);
session_destroy ();
echo "logged Out <a href='$PHP_SELF '>login</a>";
}else{
display_login_f orm();
}
}else{
logedin();
}

function user_login(){

$database="pods vij_ribepret";
mysql_connect(' localhost','pod svij','hrb3hv6g vr');
@mysql_select_d b($database) or die( "Trenutno se nije moguæe konektirati na
bazu!!");

$query = "SELECT korisnik,sifra FROM users WHERE korisnik='" .
$_POST['username'] . "'";
$result = mysql_query($qu ery);
if(!$result) die('Trenutno se nije moguce konektirati na bazu!!');
$this_user = mysql_fetch_row ($result);

if(($_POST['username'] == $this_user[0]) && ($_POST['password'] ==
$this_user[1])){

session_registe r('login');
$_SESSION['login'] = 1;

logedin();

}else{

display_login_f orm();
}
}

function display_login_f orm()
{
echo "<div align='center' class='velika_s lova'>Ako niste registrirani
korisnik, mo¾ete se registrirati <a
href='registrac ija_link.php'>o vdje</a>.</div>";

echo "<div align='center'> <form method='post' action='$PHP_SE LF'>";
echo "Korisnièko ime";
echo "<br><input type='text' name='username' >";
echo "<br>Zapork a";
echo "<br><input type='password' name='password' >";
echo "<br><input type='submit' value=' Uðite '>";
echo "</form></div>";

echo "<div align='center'> Ako ste zaboravili zaporku mo¾ete je saznati <a
href='zaboravlj ena_zaporka_lin k.php'>ovdje</a>";


}


//HERE IS THE PROBBLEM !!!
function logedin()
{
echo "$username" ; // DOES NOT WORK!!
echo "<div class='velika_s lova'>Dobrodo¹l i na korisnièke stranice portala
www.podvodni-svijet.com..</div>";
echo "<br><img src='admin/ikone/prica.gif' width='32' height='32'
align='middle'> <a href='unos_pric a_korisnici_lin k.php'>&nbsp;Do daj ribolovnu

Where is $username supposed to get its value from?

If $username is supposed to be the same as $_POST['username'], this will
work:

// function call:
logedin($_POST['username']);

// function definition:
function logedin($userna me) {

}

That's a possible way to do it. But I find that using function
parameters instead of globals is more readable and leads to code that is
easier to maintain.
