"' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>";             } elseif (isset($_cookie['window'])) {                 echo "<a style='color:" . $_cookie['color'] . "' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>";             } else {                 echo "<a style='color:" . $_cookie['color'] . "' href=" . $url . ">" . $explode2[1] . "." . $explode2[2] . "</a>";             }         }     } } 

?>

you never save $color cookie:

if (isset($_post['window'])) {   setcookie("window", $color, time() + 3600, '/');   echo "<a style='color:" . $color . "' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>"; } 

or if $color needs saved separately:

setcookie("color", $color, time() + 3600, '/'); 

personally, save session so:

session_start(); $_session['color'] = $color; 

hope helps. edit:

if (isset($_post['submit']) && (!empty($_post['url']) && (!empty($_post['title'])) {   $url = $_post['url'];   $title = $_post['title'];   $color = (($_post['color'] == $_cookie['color'])?$_cookie['color']:$_post['color']);   $explode1 = explode("/",$url);   $explode2 = explode(".",$explode1[2]);   setcookie("color", $color, time() + 3600, '/');   if (isset($_post['window'])) {     setcookie("window", $_post['window'], time()+3600, '/');     echo "<a style='color: $color' href='$url' target='_blank'>$explode2[1]}.{$explode2[2]}</a>";   } else {     echo "<a style='color: $color' href='$url'>{$explode2[1]}.{$explode2[2]}</a>";   } }
