表单成功后php重定向

Question

Using php script to allow people to add their email to a mailing list. When it successfully writes the email to the .txt doc it displays a success message on a white page. I want it to redirect to a page I've designed to look like the rest of the site. I've read elsewhere that I need to use the header function, but I can't figure out where to put it since the preceding portion of my code contains outputs.

I think this is the relevant code:

// Write to file if email doesn't already exist
    if ($emailexists != "yes") {

        // Write to the list and give success message
        fwrite($fh, "$_POST[email]
");
        $msg = "Your e-mail address $EmailFix was successfully added to the list!";
    }

    // Close the list
    fclose($fh);
}

Then this:

// Show success message if there was one and end script, and no errors were encountered
} elseif (isset($msg)) {
echo "<b>" . $msg . "</b>
";
echo "</body>
";
echo "</html>
";
exit;
}

Answer 1

Try using

header("Location: http://...");

or

header("Location: filename.php");

Make sure there's no HTML output before calling the header function!
