Javascript 如何在laravelphp中使用checbox使用ajax更新多条记录？

假设我有

csid=[1,2,3]

和

area\u id=10

我想将area id分配给cs id 所以我试过这个密码

这段代码获取（

var-id=[]

）中的所有用户ID，并获取

区域选择

，然后传递给ajax，但它响应500错误

$('#change_area_multiple').on('click', function () { // perform action 
    var ids = []
    var checkboxes = document.querySelectorAll('input[name="changearea[]"]:checked') // get all checked value of user id
        
    for (var i = 0; i < checkboxes.length; i++) {
        ids.push(checkboxes[i].value) // push all ids
    }
    console.log(ids);
    var areaselected = document.getElementById("area-select").value;
    $.ajax({
        type: "GET",
        dataType: "json",
        url: '{{ route('change.area.multiple') }}',
        data: {'areaselected': areaselected, 'user_id': ids},
        success: function (data) {
        console.log(data.message);
        }
    });
});

控制器

public function updatemultipleareas(Request $request)          
{
    for ($i = 0; i < sizeof($request->user_id); $i++) {
        $customer = Customer::find($request->user_id[i]);
        $customer->area_id = $request->areaselected;
        $customer->save();
    }
    return response()->json(['message' => 'User status updated successfully.']);
    
}

public function updatemultipleareas（请求$Request）
{
对于（$i=0；iuser_id）；$i++）{
$customer=customer:：find（$request->user_id[i]）；
$customer->area\u id=$request->areaselected；
$customer->save（）；
}
return response（）->json（['message'=>'用户状态已成功更新'）；
}

我认为我的控制器逻辑是错误的？有人能帮我吗？

找到了解决办法

 public function updatemultipleareas(Request $request)
        
        {
            $deli = $request->get('user_id');
            foreach($deli as $us_id) {
            $customer = Customer::find($us_id);
            $customer->area_id = $request->areaselected;
            $customer->save();
            }
            return response()->json(['message' => 'User status updated successfully.']);
            
        }

 public function updatemultipleareas(Request $request)
        
        {
            $deli = $request->get('user_id');
            foreach($deli as $us_id) {
            $customer = Customer::find($us_id);
            $customer->area_id = $request->areaselected;
            $customer->save();
            }
            return response()->json(['message' => 'User status updated successfully.']);
            
        }
