apache - Remove php extension of website with htaccess

Question

I have these links on my website:

http://crw4u.be/werkgever.php (I can only add 2 urls in my question, since i'm a n00b)

I added a code to htaccess so I can access these pages without the php:

http://crw4u.be/werkgever

It works fine with this code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.php [NC,L]

Yet I use certain forms in my php files:

<form name="planning" enctype="multipart/form-data" method="post" action="email/index.php">

And I'm getting errors when sending the form with the added code in htaccess:

Not Found. The requested URL /email/ was not found on this server.

Does anyone knows how to adapt this code? I've been searching and testing, but can't seem to solve this.

Highly appreciated!

Add this code also, It will let you to access directories.

RewriteCond %{REQUEST_FILENAME} !-d
