Allows to add new buttons to the toolbar above the Payment Transactions list on Order Preview page in the Administration Area.
The event handler should accept two parameter - the controller object, which you can use to render a
partial containing additional buttons and the order object. Event handler example:
public function subscribeEvents()
{
Backend::$events->addEvent('shop:onExtendOrderPaymentTransactionsToolbar', $this, 'extend_transactions_toolbar');
}
public function extend_transactions_toolbar($controller, $order)
{
$controller->renderPartial(PATH_APP.'/modules/mymodule/partials/_transactions_toolbar.htm');
}
// Example of the _transactions_toolbar.htm partial
<div class="separator"> </div>
<?= backend_ctr_button('My button', 'my_button_css_class', url('mymodule/manage/')) ?>
