Submitting a form on a custom admin page in wordpress

Question

I created a custom page in the wordpress admin which has a simple file upload field and a submit button. I need to figure out how to submit the page to somewhere it can be processed but can't find anything on the web. Does anyone know what the 'action' needs to be on the form to get it to go to a function or another page where i can process the file?

Answer 1

use this code snippet:

add_action( 'admin_action_wpse10500', 'wpse10500_admin_action' );
function wpse10500_admin_action()
{
    // Do your stuff here
    wp_redirect( $_SERVER['HTTP_REFERER'] );
    exit();
}
add_action( 'admin_menu', 'wpse10500_admin_menu' );
function wpse10500_admin_menu()
{
    add_management_page( 'WPSE 10500 Test page', 'WPSE 10500 Test page', 'administrator', 'wpse10500', 'wpse10500_do_page' );
}
function wpse10500_do_page()
{
?>
    <form method="POST" action="<?php echo admin_url( 'admin.php' ); ?>">
        <input type="hidden" name="action" value="wpse10500" />
        <input type="submit" value="Do it!" />
    </form>
<?php
}

Thanks Mr. Hunter. Couldn't credit you for the right answer.

Wrapped the form in a if(isset($_POST['submit'])) and then called my functions.
