i did foreach to get the data in my view

我做了 foreach 来获取我认为的数据

<div class="row">
    <div class="col-lg-12">
        <div class="panel panel-default">
            @foreach($role2 as $role2s)
                <button class="btn btn-primary">{{$role2s->name}}</button>

             @endforeach

            <!-- /.panel-heading -->
            <div class="panel-body">
        @if(isset($success_alert))
            <div class="alert alert-success">{{$success_alert}}</div>
        @endif
        @if(isset($danger_alert))
            <div class="alert alert-danger">{{$danger_alert}}</div>
        @endif


            @foreach($data as $dat)


                <div class="col-lg-3">
                    <button class="btn btn-default">{{$dat->name}}</button>
                    <hr>
                </div>


              <!--      <td>
                        <a href='/role-permission-confirm-delete/{{$dat->role_id}}/{{$dat->permission_id}}' class='btn btn-danger'><i class='fa fa-close'></i> Delete</a>

                       <!-- <a href='/role-permission/{{$dat->role_id}}/{{$dat->permission_id}}' class='btn btn-warning confirm'> View </a>
                    </td>-->

            @endforeach


        <!-- /.table-responsive -->

The issue would be with this piece of code, $role2s is an object. Since you are trying to print the object it is throwing the error

问题在于这段代码， $role2s 是一个对象。由于您正在尝试打印对象，因此它引发了错误

<button class="btn btn-primary">{{$role2s}}</button>

Trying running var_dump on the particular variable.

尝试在特定变量上运行 var_dump。

回答by Dhaval

curly braces are equals to PHP's echo statement. In $role2s variable you are getting object/array so it'll not print but give you an error. So you can use below solution. and after that ->or [' ']get it's object or array.

花括号等于 PHP 的 echo 语句。在 $role2s 变量中，您正在获取对象/数组，因此它不会打印但会给您一个错误。所以你可以使用下面的解决方案。然后 ->或 [' ']获取它的对象或数组。

Try

尝试

{{dd($role2s)}}

{{dd($role2s)}}

or

或者

{{print_r({{$role2s}})}}

{{print_r({{$role2s}})}}

or

或者

{{var_dump({{$role2s}})}}

{{var_dump({{$role2s}})}}

You don't have specify your exact error. But May be error is in controller. check code below

您没有指定确切的错误。但可能是错误在控制器中。检查下面的代码

$notrolepermision =DB::table('permission_role')
        ->join('permissions', 'permissions.id', '=', 'permission_role.permission_id')
        ->whereNotIn('permission_role.role_id' ,$rolepermissiongetid->role_id) //<--------------check this line you need $rolepermissiongetid->role_id in stead of $rolepermissiongetid
        ->get();

回答by ilyés Tabessi

Try to do this: it works 100%

尝试这样做：它 100% 有效

$rolepermissiongetid =DB::table('permission_role')->select('role_id')
 ->where('permission_role.role_id' , $id)
    ->get();




$arrQuery = array();
foreach($rolepermissiongetid as $key => $rolepermissiongetid){
$arrQuery[$key] = rolepermissiongetid->role_id;
 }




$notrolepermision =DB::table('permission_role')
    ->join('permissions', 'permissions.id', '=', 'permission_role.permission_id')
    ->whereNotIn('permission_role.role_id' ,$arrQuery)
    ->get();
