Laravel数组更新多行

Question

I've done a ton of looking through older posts and no luck yet, I'm trying to update multiple rows within a table from a single form with the ID being the primary key.

The contents are being displayed in what looks like a spreadsheet where the user can edit multiple rows.

I'm getting an undefined index: ID error.

The code I'm using bellow seems really close though something isn't right.

If anyones done this before and can correct this code your help would be greatly appreciated!

Thank you.

protected function updateMultiple(Request $request)

{

    $data = $request->except(['_token']);

    //  dd($data);
    for($i = 0; $i <= count($data['id']); $i++) {

        $input = [
            'id' => $data['id'][$i],
            'Channel' => $data['Channel'][$i],
            'Posts' => $data['Posts'][$i],
            'Monthly_Admin_Fee' => $data['Monthly_Admin_Fee'][$i],
            'Legal_Fee' => $data['Legal_Fee'][$i],
            'Valuation_Fee' => $data['Valuation_Fee'][$i],
            'Mortgage_Risk_Fee' => $data['Mortgage_Risk_Fee'][$i],
        ];

        DB::table('membership')->update($input);

    }

}

View

        @foreach($members as $member)
            <tr>
                <td class="text-right">
                    <input type="text" style="padding-right: 8px;padding-left: 8px;" name="id[]" id="id">{{$member->id}}</td>
                <td><input type="text" id="Channel" name="Channel[]" class="form-control" value="{{$member->Channel}}"></td>
                <td><input type="text" id="Posts" name="Posts[]" class="form-control" value="{{$member->Posts}}"></td>
                <td><input type="text" id="Monthly_Admin_Fee" name="Monthly_Admin_Fee[]" class="form-control" value="{{$member->Monthly_Admin_Fee}}"></td>
                <td><input type="text" id="Legal_Fee" name="Legal_Fee[]" class="form-control" value="{{$member->Legal_Fee}}"></td>
                <td><input type="text" id="Valuation_Fee" name="Valuation_Fee[]" class="form-control" value="{{$member->Valuation_Fee}}"></td>
                <td><input type="text" id="Mortgage_Risk_Fee" name="Mortgage_Risk_Fee[]" class="form-control" value="{{$member->Mortgage_Risk_Fee}}"></td>
            </tr>
        @endforeach

Answer 1

This will do the job

view

@foreach($members as $member)
    <tr>
        <td class="text-right">
            <input type="text" style="padding-right: 8px;padding-left: 8px;" name="id[{{$member->id}}]" id="id">{{$member->id}}</td>
        <td><input type="text" id="Channel" name="Channel[{{$member->id}}]" class="form-control" value="{{$member->Channel}}"></td>
        <td><input type="text" id="Posts" name="Posts[{{$member->id}}]" class="form-control" value="{{$member->Posts}}"></td>
        <td><input type="text" id="Monthly_Admin_Fee" name="Monthly_Admin_Fee[{{$member->id}}]" class="form-control" value="{{$member->Monthly_Admin_Fee}}"></td>
        <td><input type="text" id="Legal_Fee" name="Legal_Fee[{{$member->id}}]" class="form-control" value="{{$member->Legal_Fee}}"></td>
        <td><input type="text" id="Valuation_Fee" name="Valuation_Fee[{{$member->id}}]" class="form-control" value="{{$member->Valuation_Fee}}"></td>
        <td><input type="text" id="Mortgage_Risk_Fee" name="Mortgage_Risk_Fee[{{$member->id}}]" class="form-control" value="{{$member->Mortgage_Risk_Fee}}"></td>
    </tr>
@endforeach

controller

foreach ($request->all() as $key => $data ) {

            $input = [
                'id' => $data['id'][$key],
                'Channel' => $data['Channel'][$key],
                'Posts' => $data['Posts'][$key],
                'Monthly_Admin_Fee' => $data['Monthly_Admin_Fee'][$key],
                'Legal_Fee' => $data['Legal_Fee'][$key],
                'Valuation_Fee' => $data['Valuation_Fee'][$key],
                'Mortgage_Risk_Fee' => $data['Mortgage_Risk_Fee'][$key],

            ];
            DB::table('membership')->where('id',$key)->update($input);

        }

Answer 2

that's your problem

for($i = 0; $i <= count($data['id']); $i++) {` 

$data it's array of arrays, it doesn't have element with key 'id'

for($i = 0; $i <= count($data); $i++) {

or even better

foreach ($data as $row) {
    $desired_keys = [
        'Channel',
        'Posts',
        'Monthly_Admin_Fee',
        'Legal_Fee',
        'Valuation_Fee',
        'Mortgage_Risk_Fee',
    ];
    $input = array_only($row, $desired_keys);
    BD::table('membership')->where('id', $row['id'])->update($input)
}

EDIT

Sorry, I've missled you. Because of your approach.
Can I suggest you this one?

@foreach($members as $i => $member)
    <tr>
        <td class="text-right">
            <input type="text" style="padding-right: 8px;padding-left: 8px;" name="members[{{ $i }}][id]" id="id">{{$member->id}}
        </td>
        <td>
            <input type="text" id="Channel" name="members[{{ $i }}][Channel]" class="form-control" value="{{$member->Channel}}">
        </td>
        <td>
            <input type="text" id="Posts" name="members[{{ $i }}][Posts]" class="form-control" value="{{$member->Posts}}">
        </td>
        <td>
            <input type="text" id="Monthly_Admin_Fee" name="members[{{ $i }}][Monthly_Admin_Fee]" class="form-control" value="{{$member->Monthly_Admin_Fee}}">
        </td>
        <td>
            <input type="text" id="Legal_Fee" name="members[{{ $i }}][Legal_Fee]" class="form-control" value="{{$member->Legal_Fee}}">
        </td>
        <td>
            <input type="text" id="Valuation_Fee" name="members[{{ $i }}][Valuation_Fee]" class="form-control" value="{{$member->Valuation_Fee}}">
        </td>
        <td>
            <input type="text" id="Mortgage_Risk_Fee" name="members[{{ $i }}][Mortgage_Risk_Fee]" class="form-control" value="{{$member->Mortgage_Risk_Fee}}">
        </td>
    </tr>
@endforeach

Then in controller

protected function updateMultiple(Request $request)
{
    foreach($request->get('members', []) as $member) {
        DB::table('membership')->where('id', $member['id'])
            ->update(array_except($member, ['id']))
    }
}

This approach is much more pretty, isn't it?

Answer 3

You cannot update multiple rows with different data with one query like the insert() method.

When the data is the same for all rows that need to be updated, you can use:

DB::table('membership') ->whereIn('id', [1,2,3,4]) ->update(['Channel' => 'your-value', ..]);

Else you will need to use a foreach , if this takes to long take a look at Queing ( https://laravel.com/docs/master/queues )

Answer 4

Basically without knowing your data i would say remove [ID] .

You dont need to know the ID. remove it from everywhere in this function,

EDIT

Just change your query to: DB::table('membership')where(id, $data['id'][$i] )->update($input);

this will fetch the record with the current id and update it.

Answer 5

Mistake is in view. You have forgot to insert value to ID input.

<input type="text" style="padding-right: 8px;padding-left: 8px;" name="id[]" id="id" value="{{$member->id}}">{{$member->id}}</td>

Answer 6

you can follow like example :

$data_upate = array(
  array(
    'field1'=>'value1',
    'field2'=>'value2',
    ...
  ),
  array(
    'field1'=>'value1',
    'field2'=>'value2',
    ...
  ),
);

// list id of record you want to update//

$a_ids = array(....);

DB::table('table_name')->whereIn('id',$a_ids)->update($data_update);
