Try echoing $url then on process.php
Do
echo "Echo1: " . $url. "<br>\n";
echo "Echo2: " . $_POST['url'] . "<br>\n";
If it says Echo2 then echoes URL, then change process.php to
<?
if ($POST_['url']) {
header("Location: [url]http://www.yourdomain.com/[/url]$_POST['url']");
} else {
header("Location: form.php");
}
?>
