How to store array in Laravel?
提问by csow
There are two mysql tables 1.seats (id,number), 2.reservedseats(id,seat_id,sceering_id). I show all the seats of a specific sceering as checkboxes in show.blade:
有两个mysql表1.seats(id,number), 2.reservedseats(id,seat_id,sceering_id)。我在 show.blade 中将特定座位的所有座位显示为复选框：
{!!Form::model($screening,['method'=>'post', 'action'=>
['ReserveController@store',$screening->auditorium->id]])!!}
<input type="hidden" name="screening_id" value="{{$screening->id}}">
@foreach($seats as $seat)
<label class="checkbox-inline">
{!!Form::checkbox('seat_id[]',$seat->id,null)!!} Number: {{$seat->number}}
</label>
@endforeach
<div class='form-group'>
{!!Form::submit('Create Post',['class'=>'btn btn-primary '])!!}
</div>
{!!Form::close()!!}
When I click a checkbox it goes the the seat_id[] array. So I send a hidden input and an array with the seat_ids then I want to store in the reservedseats Mysql table. But in the store controller I have the problem. I'm trying something like:
当我点击一个复选框时，它会进入seat_id[] 数组。所以我发送一个隐藏的输入和一个带有seat_ids的数组，然后我想存储在reservedseats Mysql表中。但是在商店控制器中我遇到了问题。我正在尝试类似的东西：
public function store(Request $request){
$screening_id = $request->screening_id;
$seat_ids = $request->seat_id;
foreach($seat_ids as $seat_id){
Seatreserved::create($seat_id,$screening_id);
}
}
So it not working but how can I solve that?
所以它不起作用，但我该如何解决？

Try this code
试试这个代码
public function store(Request $request)
{
$screening_id = $request->screening_id;
$seat_ids = $request->seat_id;
foreach($seat_ids as $seat_id) {
Seatreserved::create([
'seat_id' => $seat_id,
'screening_id' => $screening_id
]);
}
}
Also you can use
你也可以使用
public function store(Request $request)
{
$screening_id = $request->screening_id;
$seat_ids = $request->seat_id;
$data = [];
foreach($seat_ids as $seat_id) {
$data[] = [
'seat_id' => $seat_id,
'screening_id' => $screening_id
];
}
Seatreserved::insert($data);
}

You can also create a new instance of your model to store values.
您还可以创建模型的新实例来存储值。
Example:
例子：
foreach($seat_ids as $seat_id) {
$reserved = new Seatreserved();
$reserved->seat_id = $seat_id;
$reserved->screening_id = $screening_id;
$reserved->save();
}
