从 foreach table 将多选值插入数据库

Question

我有上面的 table，最后一列是一个多 select 下拉列表，其中可以 select 多个国家/地区。我在将每一行的 select 值插入 table 时遇到问题我要插入的代码如下

<div class="container-flow">
<table id="table" class="table table-hover table-bordered table-sm text-center">
<thead style="background-color:#00BFFF;">
<tr>
<th class="fixed" scope="col"> No.</th>
<th class="fixed" scope="col">Price List</th>
<th scope="col">Level One</th>
<th scope="col">Level Two</th>
<th scope="col">Level Three</th>
<th scope="col">Level Four</th>
<th scope="col">Level Five</th>
<th scope="col">Level Six</th>
<th scope="col">Level Seven</th>
<th scope="col">Level Eight</th>
<th scope="col">Level Nine</th>
<th scope="col">Level Ten</th>
<th width='150px' scope="col">Assigned Country</th>

</tr>
</thead>
<tbody>
<?php $i = 1 ?>
@foreach ($pricing as $price)
<tr>
<td class="fixed_td">{{  $i++}}</td>
<input type="hidden" name="price_list[]" value="{{$price->id}}">
<td class="fixed_td">{{$price->type_name}}</td>
<td><input type="checkbox"  name="level_one[]" class="check" value="1"><input type="hidden"  name="level_one[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_two[]" class="check" value="1"><input type="hidden"  name="level_two[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_three[]" class="check" value="1"><input type="hidden"  name="level_three[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_four[]" class=" check" value="1"><input type="hidden"  name="level_four[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_five[]" class=" check" value="1"><input type="hidden"  name="level_five[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_six[]" class="check" value="1"><input type="hidden"  name="level_six[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_seven[]" class="check" value="1"><input type="hidden"  name="level_seven[]" class="check" value="0"></td>
<td><input type="checkbox"   name="level_eight[]" class=" check" value="1"><input type="hidden"  name="level_eight[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_nine[]" class="check" value="1"><input type="hidden"  name="level_nine[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_ten[]" class="check" value="1"><input type="hidden"  name="level_ten[]" class="check" value="0"></td>
<td>
<select id="country_id" name="country_id[{{$loop->index}}][]"  class="form-control country_id" multiple="multiple">
@foreach ($countrys as $country)
<option value="{{$country->id}}">{{$country->country_name}}</option>
@endforeach  
</select>
</td>
</tr>
@endforeach
</tbody>
</table>
</div>
</form>  
</div>

我想在 database.The 问题中得到如下所示的结果是获取每行的多个 select 值

<td><input type="checkbox"  name="level_one[]" class="check" value="1"><input type="hidden"  name="level_one[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_two[]" class="check" value="1"><input type="hidden"  name="level_two[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_three[]" class="check" value="1"><input type="hidden"  name="level_three[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_four[]" class=" check" value="1"><input type="hidden"  name="level_four[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_five[]" class=" check" value="1"><input type="hidden"  name="level_five[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_six[]" class="check" value="1"><input type="hidden"  name="level_six[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_seven[]" class="check" value="1"><input type="hidden"  name="level_seven[]" class="check" value="0"></td>
<td><input type="checkbox"   name="level_eight[]" class=" check" value="1"><input type="hidden"  name="level_eight[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_nine[]" class="check" value="1"><input type="hidden"  name="level_nine[]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_ten[]" class="check" value="1"><input type="hidden"  name="level_ten[]" class="check" value="0"></td>
<td>
<select id="country_id" name="country_id[]" class="form-control country_id" multiple="multiple">
@foreach ($countrys as $country)
<option value="{{$country->id}}">{{$country->country_name}}</option>
@endforeach  
</select>
</td>

Answer 1

使用 implode 将数组 [1, 2, 3, 4,] 转换为字符串 "1,2,3,4"


'country_id'=> implode(',', $request->input('country_id')[$i]??[]),

您的 select 输入需要以 [] 结尾的名称属性值才能作为数组发送。

例子

<select name="country_id[1][]">
    //.....
</select>

编辑：

将您的select输入设置为

@foreach ($pricing as $price)
<tr>
<td class="fixed_td">{{$loop->iteration}}</td>
<input type="hidden" name="price_list[{{$loop->index}}]" value="{{$price->id}}">
<td class="fixed_td">{{$price->type_name}}</td>
<td><input type="checkbox"  name="level_one[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_one[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_two[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_two[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_three[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_three[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_four[{{$loop->index}}]" class=" check" value="1"><input type="hidden"  name="level_four[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_five[{{$loop->index}}]" class=" check" value="1"><input type="hidden"  name="level_five[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_six[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_six[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_seven[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_seven[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"   name="level_eight[{{$loop->index}}]" class=" check" value="1"><input type="hidden"  name="level_eight[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_nine[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_nine[{{$loop->index}}]" class="check" value="0"></td>
<td><input type="checkbox"  name="level_ten[{{$loop->index}}]" class="check" value="1"><input type="hidden"  name="level_ten[{{$loop->index}}]" class="check" value="0"></td>
<td>
<select id="country_id" name="country_id[{{$loop->index}}][]"  class="form-control country_id" multiple="multiple">
@foreach ($countrys as $country)
<option value="{{$country->id}}">{{$country->country_name}}</option>
@endforeach  
</select>
</td>
</tr>
@endforeach

我能够解决这个问题，这对我有用

  $this-> validate($request,[
            'user_id'=>'required',
           
        ]); 
        $count = count($request->input('price_list',[]));
                     
       
        $permission = new Permission;
        for ($i=0; $i<$count; $i++){
        // $country_id =$request->input('country_id',[])[$i];
        
        // print_r(implode(',', $request->input('country_id')));
       
        
             
        $data[] = array(
        'user_id' =>$request->input('user_id'),
        'price_list'=>$request->input('price_list')[$i], 
        'level_one'=>$request->input('level_one')[$i], 
        'level_two'=>$request->input('level_two')[$i],
        'level_three'=>$request->input('level_three')[$i],
        'level_four'=>$request->input('level_four')[$i], 
        'level_five'=>$request->input('level_five')[$i],
        'level_six'=>$request->input('level_six')[$i],
        'level_seven'=>$request->input('level_seven')[$i], 
        'level_eight'=>$request->input('level_eight')[$i],  
        'level_nine'=>$request->input('level_nine')[$i],  
        'level_ten'=>$request->input('level_ten')[$i], 
        'country_id'=> implode(',', $request->input('country_id',[])[$i]),
        'created_at'=>Carbon::now(),     

         );
         }
           
        // dd($data);
           
        Permission::insert($data);
         return redirect()->back()->with('success', 'Permissions Created Successfully');

我在尝试更新复选框时遇到另一个问题

 <td><input type="checkbox"  name="level_one[]" class="check" value="1" {{($perm->level_one == 1 ? ' checked' : '') }}><input type="hidden"  name="level_one[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_two[]" class="check" value="1" {{($perm->level_two == 1 ? ' checked' : '') }}><input type="hidden"  name="level_two[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_three[]" class="check" value="1"{{($perm->level_three == 1 ? ' checked' : '') }}><input type="hidden"  name="level_three[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_four[]" class=" check" value="1"{{($perm->level_four == 1 ? ' checked' : '') }} ><input type="hidden"  name="level_four[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_five[]" class=" check" value="1" {{($perm->level_five == 1 ? ' checked' : '') }}><input type="hidden"  name="level_five[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_six[]" class="check" value="1" {{($perm->level_six == 1 ? ' checked' : '') }}><input type="hidden"  name="level_six[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_seven[]" class="check" value="1" {{($perm->level_seven == 1 ? ' checked' : '') }}><input type="hidden"  name="level_seven[]" class="check" value="0"></td>
    <td><input type="checkbox"   name="level_eight[]" class=" check" value="1" {{($perm->level_eight == 1 ? ' checked' : '') }}><input type="hidden"  name="level_eight[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_nine[]" class="check" value="1" {{($perm->level_nine == 1 ? ' checked' : '') }}><input type="hidden"  name="level_nine[]" class="check" value="0"></td>
    <td><input type="checkbox"  name="level_ten[]" class="check" value="1" {{($perm->level_ten == 1 ? ' checked' : '') }}><input type="hidden"  name="level_ten[]" class="check"  value="0" ></td>

隐藏输入不是工作问题我怎么能在没有隐藏输入的情况下工作，因为当我像检查一样编辑下面的十列[！[在此处输入图像描述] [1]] [1] 当该列的 dd($data) 我应该得到 111111111 但当我删除隐藏时我得到 0101010101 它工作正常但如果没有勾选一个复选框会给出偏移错误

我的更新控制器是这样的

public function update(Request $request, $id)
    {
    $this-> validate($request,[
        'user_id'=>'required',
        
    ]); 
    $ids = $request->input('id',[]);

    foreach($ids as $key => $value){ 

    $permission = Permission::find($request->id[$key]); 
    $permission->level_one = $request->level_one[$key]; 
    $permission->level_two = $request->level_two[$key];
    $permission->level_three = $request->level_three[$key];
    $permission->level_four = $request->level_four[$key];
    $permission->level_five = $request->level_five[$key];
    $permission->level_six = $request->level_six[$key];
    $permission->level_seven = $request->level_seven[$key];
    $permission->level_eight = $request->level_eight[$key];
    $permission->level_nine = $request->level_nine[$key];
    $permission->level_ten = $request->level_ten[$key];  
    $permission->country_id =implode(',', $request->input('country_id',[])[$key]??[]);

    // print($permission);

  
    $permission->save(); 
    }
    // return($permission);
    //  print($permission);

    return redirect()->back()->with('success', 'Permissions Updated Successfully');

我应该更改什么才能使更新正常工作 [1]: https://i.stack.imgur.com/L8vIb.png
