Pozdrav,

Pre svega zelim svima da pozelim srecnu Novu godinu

Imam sledeci problem. Na jednoj strani imam link koji otvara popup prozor u kome se pojavljuje twitter aplikacija za prijavljivanje. Nakon klika na "Allow" popup prozor se zatvara, JS funkcija prikuplja $GET parametre iz URL-a, prosledjuje maticnoj strani i refresuje je sa dodatkom prikupljenih parametara. Problem je sledeci...nakon refresovanja maticne strane, ona ponovo poziva funkciju koja prikuplja $_GET parametre iz URL-a i u konzoli dobijam gresku "Cannot read property 'location' of null"...Evo koda, nadam se da cete mi pomoci

<?php
session_start();
require_once 'include/twitter.class.php';
echo "Dobrodosli ".$_SESSION['login']."! <br />";
?>
<script type="text/javascript"> 
function twitter()
{
	
	window.open('./login.php?action=twitter','myWin','scrollbars =yes, width=500,height=500');
	window.onClick = function(){self.close()};
}
function gup( name )
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results != null )
	  return results[1];
  
    
}

function callTwitter()
{
	var a = gup('oauth_verifier');
	var b = gup('oauth_token');
	
		window.close();
		window.opener.location.search = '?oauth_token='+b+'&oauth_verifier='+a;
		
	
}
</script>
<a href="javascript:;" onClick="twitter();">Open Window</a>
<?php 
echo '

<a href="?action=twitter">Register Twitter</a><br />
<form action="login.php" method="post">
<input type="submit" name="logout" value="Log Out"/>
</form>
';
if(isset($_POST['logout']))
{
	unset($_SESSION['login']);
	unset($_SESSION['konektovan']);
	session_unset();
	header( "refresh:1;url=index.php" );
}
if(isset($_GET['action'])=="twitter")
{
	
	$t = new Twitter();
	$t->twitterLogin();
}


if(!empty($_GET['oauth_verifier']) && !empty($_SESSION['oauth_token']) && !empty($_SESSION['oauth_token_secret']))
{
		
	
		echo '<script type="text/javascript">callTwitter();
		</script>';
	
	
		
		echo 'Uspesno konektovanje sa twitterom';
		
		
		
		
	}
