    In controller, you should replace

    $data = ['item' => $item];

    to

    $data = ['data' => $item];

    Or

    $item = $this->item_m->get()->result();
$this->template->load('template','transaction/sale/sale_form', array('data' => $item));

    ## from your controller ##
$data = ['item' => $item];
$this->template->load('template','transaction/sale/sale_form', $data);

## your view should be ##
<?php foreach ($item as $i => $data) : ?>
<?php endforeach: ?>

    $data = ['item' => $item];
    from your controller you can access your data by print_r($data[‘item’]);
    but from your view/template you access it by the array name hence, print_r($item);

    $data['itemData'] = $item;
    from controller, print_r($data[‘itemData’]);
    from your view/template, print_r($itemData);
