我想在表的每一行插入一个按钮，当我单击此按钮时，它将我重定向到使用Laravel的单个表行的数据的另一个页面我该怎么做呢?
这是我的表单:
<html>
<table class="table">
<thead>
<tr>
<th scope="col">ID</th>
<th scope="col">USERNAME</th>
<th scope="col">MAC ADDRESS</th>
</tr>
</thead>
<tbody>
@foreach ($data as $item)
<tr>
<th scope="row">{{$item->id}}</th>
<td>{{$item->username}}</td>
<td>{{$item->mac_addr}}</td>
<td>
<form action="{{url('singleDevice')}}" method="get">
<button class="btn btn-primary" type="submit">Select</button>
</form>
</td>
</tr>
@endforeach
</tbody>
</table>
</body>
</html>
这是我的控制器
class DeviceController extends Controller
{
public function index()
{
$data=Device::all();
return view('device', compact("data"));
}
public function create()
{
return view('registrationDevice');
}
public function store(Request $request)
{
$input = new Device;
//On left field name in DB and on right field name in Form/view
$input -> username = $request->username;
$input -> mac_addr = $request->mac_address;
$input->save();
return redirect('registrationDevice')->with('message', 'DATA SAVED');
}
public function show(Device $device)
{
return view('singleDevice');
}
}
Thanks in advance
把你的表单改成:
<tbody>
@foreach ($data as $item)
<tr>
<th scope="row">{{$item->id}}</th>
<td>{{$item->username}}</td>
<td>{{$item->mac_addr}}</td>
<td>
<a href="{{ url('/singleDevice/'.$item->id) }}" class="btn btn-primary">Select</a>
</td>
</tr>
@endforeach
</tbody>
如果你想使用路由名
<td>
<a href="{{ route('show', ['deviceID' => $item->id]) }}" class="btn btn-primary">Select</a>
</td>
改变你的路由:
Route::get('/singleDevice/{deviceID}', [DeviceController::class, 'show'])->name('show');
更改控制器的show功能，如:
public function show($deviceID)
{
$device = Device::firstWhere('id', $deviceID);
return view('singleDevice', compact("device"));
}
为什么需要表单?使用链接
<form action="{{url('singleDevice')}}" method="get">
<button class="btn btn-primary" type="submit">Select</button>
</form>
替换为
<a href="{{ route('show', ['device' => $item->id]) }}" class="btn btn-primary">Select</a>
，并在路由器中配置URL为/singleDevice/{device}
Route::get('/singleDevice/{device}', [DeviceController::class, 'show'])->name('show');
你也可以在你的代码中使用form
<form action="{{ route('show', $item->id) }}" method="get">
<button class="btn btn-primary" type="submit">Select</button>
</form>
public function show(Device $device)
{
return view('singleDevice');
}
For Route you can pass$device:
Route::get('/singleDevice/{$device}', [DeviceController::class, 'show'])->name('show');
