找不到列：1054字段列表中的未知列'0'

Question

i have 3 forms in one page using ajax for them. Edit form is getting error as below. I dont know why i am getting this error. I am beginner . error while submitting form:

"SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: update user_profiles set 0 = , updated_at = 2018-08-18 10:25:43 where id = 1)"

This is my edit button code:

 <a class="btn btn-primary" href="javascript:void(0);" onclick="editExchangeMarket({{$user_profiles->id}});"> <span class="glyphicon glyphicon-edit"></span> Edit </a> 

This is my modal and ajax code:

 <script> function updateExchangeMarket() { var edit_fid = $('#edit_fid').val(); var edit_charge_per_lot = $('#edit_charge_per_lot').val(); $('#exchangeMarketModal').modal('show'); // alert(values); $.ajax({ headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') }, url: "{{URL::to('user/updateExchangeMarket')}}", data:{'id' : edit_fid, 'edit_charge_per_lot':edit_charge_per_lot}, method:'POST', success: function( resp ) { }, error: function( req, status, err ) { console.log( 'something went wrong', status, err ); } }); } </script> 

 <div id="exchangeMarketModal" class="modal fade" role="dialog"> <div class="modal-dialog"> <!-- Modal content--> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">&times;</button> <h4 class="modal-title">Modal Header</h4> </div> <div class="modal-body"> <form id="exchangeMarketForm" name="exchangeMarketForm" > <input type="hidden" class="form-control" id="edit_fid" value="1"> <div class="col-md-6 mb-3 form-group"> chargeperlot: <input type="text" name="edit_charge_per_lot" id="edit_charge_per_lot" class="form-control"><br> </div> </form> </div> <div class="modal-footer"> <a type="submit" href="javascript:void(1);" onclick="updateExchangeMarket({{$user_profiles->id}});" value="Submit" class="btn btn-primary">Save changes</a> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> 

Now i am adding here my controller code:

        public function updateExchangeMarket(Request $request)
    {
        $id = $request->id;    
        $charge_per_lot = $request->edit_charge_per_lot;

        $data = array('country_id'=>$country_id,
            'id'=>$id,
            'charge_per_lot'=>$charge_per_lot,

        );
        $res = UserProfile::where('id',$id)->update([$data]);
        echo json_encode($res);
    }

Answer 1

Update() takes an assocative array to update the values. your $data is already an associative array so no need to push it as an array.

$data = array('country_id'=>$country_id,
            'id'=>$id,
            'charge_per_lot'=>$charge_per_lot,

        );
        $res = UserProfile::where('id',$id)->update($data)

Answer 2

UserProfile::where('id',$id)->update(
[
  'name' => $name,
  'number' => $number
]);

by this way you can do query if you have mutiple parameters & values to query
