Fastadmin adds batch action button function

index.html

<a href="javascript:;" class="btn btn-info btn-check-back hidden" title="{:__('check-back')}" ><i class="fa fa-trash" ></i> {:__('Verify Chargeback')}</a>

corresponds to js

$(".btn-check-back").on('click',function() {
var that = this;
var ids = Table.api.selectedids(table);
Layer.prompt({title: __('Please enter the time (unit: minutes)'), formType: 0}, function (value, index){
Backend.api.ajax({
url: "dy/task_order/multi?action=mback&m=" + value + "&ids=" + ids,
data: $(that).closest("form").serialize()
},function() {
$(".btn-refresh").trigger("click");
Layer.close(index);
});

});
});

Corresponding logic processing

public function multi($ids = "")
{
    ...

    if($this->request->param('action') == 'back') {
        $ids = explode(',',$ids);
        $success = 0;
        $error = 0;
        $count = count($ids);
        foreach($ids as $id) {
            $order = \app\admin\model\Dy\TaskOrder::find($id);
            if (!$order || $order->status != TaskOrderStatus::ING || !$order->vid) {
                $error++;
                continue;
            }
            if($order->channel == OrderChannelEnum::PLATFORM) {
                $ret = \app\admin\model\Dy\TaskOrder::backOrderForIn($order->id,'Background manual refund',BackLogType::ADMIN_ACTION,'Background manual refund');
                $ret === true and $success = $success + 1 or $error = $error + 1;
            } else {
                $ret = \app\admin\model\Dy\TaskOrder::backOrderForOut($order->order_id,BackLogType::ADMIN_ACTION,'Background manual refund');
                $ret === true and $success = $success + 1 or $error = $error + 1;
            }
        }
        $this->success("Processing: {$count}, successful chargeback: {$success}, unsuccessful chargeback: {$error}");
    }
    ...

}
