Question

I am using the following processor to send name, email and phone to a flatfile.

<?php
$vname = $_GET["visitor"];
$vemail = $_GET["visitormail"];
$vphone = $_GET["visitorphone"];
print("<b>Thank You!</b><br />Your information will be entered once into the raffle!");
$out = fopen("savedinfo.php", "a");
if (!$out) {
print("Could not append to file");
exit;
}
fputs ($out, "\n");
fwrite($out,"$vname, $vemail, $vphone.");
fclose($out);
?>

I have tried various means to likewise send the ip address to the flatfile but cannot get to work!

I start with this line <input type="hidden" name="ip" value="<?php echo $ipi ?>" />

and seek to achieve a result as follows fwrite($out,"$vname, $vemail, $vphone, $ipi.");

Use $_SERVER['REMOTE_ADDR'];. This is standard PHP.

You can view a list of all available $_SERVER values here: http://php.net/manual/en/reserved.variables.server.php
