PHP表单和.htaccess冲突

I have a couple simple contact forms on my page. All was working well (form was sent to the email in the script) until I added this .htaccess file.

Is there a way to process the php form while also including the .htaccess file? (because it made the site look really nice)

Thanks in advance.

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

## hide .php extension
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L,NC]

## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [L]

FORM CODE:

<?php
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];

$from = 'From: Contact Page';
$to = 'xxxx@xxx.com';
$subject = 'Contact Page';
$human = $_POST['human'];

$body = "From: $first_name
 $last_name
 E-Mail: $email
 Phone: $phone
 Message:
 $message";

if ($_POST['submit'] && $human == '4') {

    if (mail ($to, $subject, $body, $from)) {
        header('Location: http://www.xxxxxx.com/ThankYou.php');
        exit();
    } else {
        header('Location: http://www.xxxxxx.com/error.php');
    }
} else if ($_POST['submit'] && $human != '4') {
    header('Location: http://www.xxxxxx.com/error.php');;
}
?>

You need to disable POST method from first redirect rule since external redirect will not carry POST data to new URL. Use this code:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

## hide .php extension
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=302,L,NE]

## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [L]

btw this full .htaccess smells like one of my old answers on SO :)
