How to prevent the form from redirection after submission in order to see the kpr() results?

Question

I installed Basic Cart module and I needed to completely modify its submission handler. So I used the following code:

function THEME_form_alter(&$form, &$form_state, $form_id){
    if($form_id == 'order_node_form'){
        $form['#submit'] = array("my_form_order_submit_handler");
    }
}

and It works perfectly. The order_node_form form has some values in its inputs and I need to get them. I don't know how to get the values from the $form variable so I need to kpr this variable. This is the my_form_order_submit_handler function:

function my_form_order_submit_handler($form, &$form_state) {
    kpr(1);
}

The problem is it doesn't kpr the 1 and is redirected to some where else. In the question kpr() in my form validation and submit function is not being called it has been suggested to add the following codes in form alter function and tried this code:

function THEME_form_alter(&$form, &$form_state, $form_id){
    if($form_id == 'order_node_form'){
        $form['#submit'] = array("my_form_order_submit_handler");
        $form_state['rebuild'] = TRUE;
        $form_state['no_redirect'] = TRUE;
        $form_state['redirect'] = FALSE;
    }
}

But it is still redirected and I can't see the kpr(1) result in the submission function. How can I prevent the page being redirected to some where else after the my_form_order_submit_handler function?

Thanks

You can call die() after kpr().
