Cookie should initiate redirect, but flash stops it

Hi there,

I have the following code on one of my sites as intro page

PHP Code:


			
<?PHP

    

    //Coded by lightning-hosting (max)

    //Counter Agency Intro Page, setting cookies for first visits, so intro only shows on first time

    

    

    if(isset($_GET['show'])) {

    

        if($_GET['show'] == 'yes') {

        

            setcookie("cacomintroskip","skip",time()-60*60*24*7*365);

            echo "Cookie delteted";

            

        }

        

    }



    if(isset($_COOKIE['cacomintroskip'])) {



        if($_COOKIE['cacomintroskip'] == 'skip') {

        

        echo "<meta http-equiv=\"refresh\" content=\"0; URL=http://www.counter-agency.com/portal\">";

        exit();

        

        

        }

        

    }

    

    

    if(isset($_GET['skip'])) {

        

        if($_GET['skip'] == 'true') {

        

        echo "<meta http-equiv=\"refresh\" content=\"0; URL=http://www.counter-agency.com/portal\">";

            

            

        }

        

    }

        

    if(isset($_GET['dontshowagain'])) {

        

        if($_GET['dontshowagain'] == 'true') {

        

            setcookie("cacomintroskip","skip",time()+60*60*24*7*365);

            echo $_COOKIE['counter-agency.com_introskip'];

            echo "<meta http-equiv=\"refresh\" content=\"0; URL=http://www.counter-agency.com/portal\">";

            

            

        }

    

    }

    

?>





<html>

    <head>

        <title>Counter-Agency.com - Greatest (S)hit</title>

        <meta http-equiv="content-type" content="text/html;charset=iso-8859-1">

        <script src="foo.js" type="text/javascript"></script>

        <link href="class.css" rel="stylesheet" media="screen">

    </head>

    

    <body bgcolor="#333333">

        <p align="center">

        <br /><br /><br /><br><br><br>

        

        <script type="text/javascript">RunFoo();</script>





        <br /><br /><br />

        <font color="#999999" face="Arial, Helvetica, sans-serif">

        <table border="0" align="center" width="50%">

            <tr>

                <td align="left"><a href="index.php?skip=true">Intro überspringen</a></td>

                <td align="right"><a href="index.php?dontshowagain=true">Nicht mehr zeigen</a></td>

            </tr>

        </table>

        </font>

        </p>

        

    </body>

</html>

The problem is that if I set the cookie, this should not be displaying anymore, but somehow the flash is stopping an immediate redirect, I tried with exit and everything but nothing works. Once the page is loaded and I press F5 (refresh) suddenly it recognizes the cookie and redirects me.

Does anybody know why that is?

PS: You might wonder what the javascript does, the script in the header includes the function run_foo, and runfoo will simply print my flash code, so that the border around flash is not shown since the new Microsoft "UPDATE".

Thanks for any help
best regards

Any cookie variable $_COOKIE['...'] in the PHP script is not actually set when you do the setcookie(...) statment. The setcookie causes the cookie to be sent to the browser, but this is not sent back to a PHP script until the page is refreshed or is revisited (headers exchanged with the browser, which gives the cookies for your domain to the server.)

From the PHP manual -

Quote:

Common Pitfalls:
Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);.

You can fake this to make your code work by setting the cookie variable at the same time you do the setcookie -

PHP Code:


			
setcookie("cacomintroskip","skip",time()-60*60*24*7*365);

$_COOKIE['cacomintroskip'] = 'skip';
