Laravel Array转换为字符串转换错误

I want to store data from a form into two tables on database when the radio button value on my view is "new", but the below problem was happened. But if the value is "existing", it's works fine. what wrong with my code ?

Array to string conversion (SQL: insert into customers (company_name, address, service_id, tc_name, tc_dept, tc_phone, tc_email, bill_name, bill_dept, bill_phone, bill_email, updated_at, created_at) values (PT Bank ABC, JL Sudirman, 1, Budi, Technical, 0812345678, budi@abc.co.id, Joko, Finance, 08123456789, joko@abc.co.id, 2016-12-14 11:21:26, 2016-12-14 11:21:26))

here my store code

if($request->select_data == 'new'){
        $customer = New Customer;
        $customer->company_name = $request->company_name;
        $customer->address = $request->address;
        $customer->service_id = $request->service_id;
        $customer->tc_name = $request->tc_name;
        $customer->tc_dept = $request->tc_dept;
        $customer->tc_phone = $request->tc_phone;
        $customer->tc_email = $request->tc_email;
        $customer->bill_name = $request->bill_name;
        $customer->bill_dept = $request->bill_dept;
        $customer->bill_phone = $request->bill_phone;
        $customer->bill_email = $request->bill_email;
        $customer->save();

        $salesorder = New SalesOrder;
        $salesorder->pid = $request->pid;
        $salesorder->project_name = $request->project_name;
        $salesorder->customer_id = $request->company_id;
        $salesorder->total = $request->totalfee;
        $salesorder->status = 'submit';
        $salesorder->detail = $request->detail;
        $salesorder->save();
    }else{
        $salesorder = New SalesOrder;
        $salesorder->pid = $request->pid;
        $salesorder->project_name = $request->project_name;
        $salesorder->customer_id = $request->company_id;
        $salesorder->total = $request->totalfee;
        $salesorder->status = 'submit';
        $salesorder->detail = $request->detail;
        $salesorder->save();
        //dd($salesorder);

radio button html code

<div class="row-fluid select_data">
                        <input name="select_data" id="select_data" type="radio" value="new">
                        <span class="lbl">New</span>
                        <input name="select_data" id="select_data" type="radio" value="existing">
                        <span class="lbl">Existing</span>
                    </div>

The problem is because some of $request properties are arrays. You can't store an array in integer, string etc columns. If you want to store them as arrays, you can serialize them:

$customer->service_id = json_encode(service_id);

And store in text or json columns:

$table->json('service_id');
$table->text('service_id');

Try to change id of both the radio buttons, you can not set same id for different elements, it will behave differently

Try this one

<input name="select_data" name="select_data" type="radio" value="new">
                        <span class="lbl">New</span>
                        <input name="select_data" name="select_data" type="radio" value="existing">
                        <span class="lbl">Existing</span>
