Make a custom admin footer text

When creating a site for a customer you might want to brand WordPress backend.

At the bottom of the admin interface there is the following text.

Thank you for creating with WordPress. | Documentation | Feedback

To change this text simply add this function in the functions.php file located in you theme folder. If this file doesn’t exist simple create it.

function custom_footer_admin () {
	echo 'Add you custom footer text here';
}
add_filter('admin_footer_text', 'custom_footer_admin');
