Twitter bootstrap &引用；未定义变量"；搜索功能

我试图为从数据库获取和保存数据的表设置搜索功能。目前，我的表可以查看数据库中的数据，但无法搜索。 下面是我显示数据的表格

<table class="table">
                    <thead class=" text-primary">
                        <th>
                            Brand Name
                        </th>
                        <th>
                            Phone
                        </th>
                        <th>
                            Reg No.
                        </th>
                        <th>
                            Certificate
                        </th>
                        <th>
                            Email
                        </th>
                        <th>
                            User-Role
                        </th>
                        <th>
                            Edit
                        </th>
                        <th>
                            Delete

                    </thead>
                    <tbody>
                        @foreach($user as $receiver)
                        <tr>

                            <td>

                            </td>
                            <td>
                                {{$receiver->certificate}}
                            </td>
                            <td>
                                {{$receiver->email}}

                            </td>
                            <td>

                                    {{csrf_field()}}
                                    {{method_field('DELETE')}}
                                    <button class="delete btn btn-danger" type="submit">Delete</button>
                                </form>
                            </td>
                        </tr>
                        @endforeach

                        <script>
                            $(".delete").on("submit", function(){
                                return confirm("Are you sure?");
                            });
                        </script>
                    </tbody>
                </table>

路线呢

Route::any('/searchorg','Admin\OrganizationController@search');

每当我在搜索表单上搜索某个内容时，它都会出现错误“undefined variable:q1”

我将感谢任何帮助。谢谢

您应该更改控制器：

public function search(Request $request)
{
    $q1 = Input::get( 'q1' );

    if( !empty( $q1 ) ) {

        $user1 = User::where('name','LIKE','%'.$q1.'%')->orWhere('email','LIKE','%'.$q1.'%')->orWhere('phone','LIKE','%'.$q1.'%')->orWhere('usertype','LIKE','%'.$q1.'%')->orWhere('regno','LIKE','%'.$q1.'%')->orWhere('lat','LIKE','%'.$q1.'%')->orWhere('long','LIKE','%'.$q1.'%')->get();
        if(count($user1) > 0){
            return view('admin.register')->withDetails('user',$user1);
        } else { 
            return view ('admin.register')->withMessage('No Details found. Try to search again !');
        }
    } else { 
        $user = User::where('usertype', 'organization')->get();
        return view('admin/organization.organizations')->with('user',$user);
    }
}

您应该在控制器中进行更改：

public function search(Request $request)
{
    $q1 = Input::get( 'q1' );

    if( !empty( $q1 ) ) {

        $user1 = User::where('name','LIKE','%'.$q1.'%')->orWhere('email','LIKE','%'.$q1.'%')->orWhere('phone','LIKE','%'.$q1.'%')->orWhere('usertype','LIKE','%'.$q1.'%')->orWhere('regno','LIKE','%'.$q1.'%')->orWhere('lat','LIKE','%'.$q1.'%')->orWhere('long','LIKE','%'.$q1.'%')->get();
        if(count($user1) > 0){
            return view('admin.register')->withDetails('user',$user1);
        } else { 
            return view ('admin.register')->withMessage('No Details found. Try to search again !');
        }
    } else { 
        $user = User::where('usertype', 'organization')->get();
        return view('admin/organization.organizations')->with('user',$user);
    }
}

q1

取消定义，因为您在

$q

中分配了
