TextMate snippet for PRG-pattern in WordPress

This is free TextMate snippet day here at jonasnordstrom.se. Enjoy, and please let me know if there are any errors.

From wikipedia:

Post/Redirect/Get (PRG) is a web development design pattern that prevents 
some duplicate form submissions, creating a more intuitive interface for 
user agents (users). PRG implements bookmarks and the refresh button in a 
predictable way that does not create duplicate form submissions.

PRG is the pattern to aim for when creating functionality for the WordPress backend (wp-admin). But it’s a pain to keep track of which hooks to use, how the redirection works and stuff like that.
Here’s a TextMate snippet that hopefully will be of some help.

Note: I will add nonce and update this post, just wanted to save the code somewhere when it was in front of me, you know how it is …

function ${1:function_name}_page() {

    if ( isset( $POST['action'] ) && !current_user_can( '${2:edit_page}' ) ) {
    } ?>

    <form action="edit.php" method="post">
        <input type="hidden" name="page" value="${1/\_/-/}-page" />
        <input type="hidden" name="action" value="${3:action-name}" />
        <input type="submit" value="${4:Button Text}" />
function $1() {
    if ( isset(\$_POST['action']) && \$_POST['action'] == '$3') {
        // Do your magic here

        \$location = admin_url() . "edit.php?page=" . $_POST['page'] . "&feedback=${5:Feedback+here}";

        \$status = 302;
        wp_redirect( \$location, \$status );
function add_$1_page() {
    add_management_page( '${6:Page Title}', '${7:Menu Title}', '${8:manage_options}', 
                  '${9:menu-slug}', '${1:function_name}_page' );

add_action( 'admin_init', '$1' );
add_action( 'admin_menu', 'add_$1_page' );
