[JavaScript][PHP] Ustawienie sesji Opcje

[k.kobyk]

Mam kod, który uzupełnia mi pola na podstawie geolokalizacji

[PHP] pobierz, plaintext 
    <?php
    session_start();
    if(!isset($_SESSION['id'])){
    echo $latitude;
    ?>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.9.0.min.js"></script>
    <script type="text/javascript">
    function getCoordPosition()
    {
        if(navigator.geolocation)
        {
            navigator.geolocation.getCurrentPosition(function(position){
                var latitude = position.coords.latitude;
                var longitude = position.coords.longitude;
 
                var form = $("form");
                form.find("input[name='latitude']").val(latitude);
                form.find("input[name='longitude']").val(longitude);
            });
        }
    }
    window.onload = getCoordPosition
    </script>
    <form enctype="multipart/form-data" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="latitude" value="">
    <input type="text" name="longitude" value="">
    </form>
    <?php
    }
    ?>
[PHP] pobierz, plaintext 

Jednak jest problem z start_session

Warning: session_start() [function.session-start]: Cannot send session cookie
Warning: session_start() [function.session-start]: Cannot send session cache limiter

Macie pomysł jak to rozwiązać?
