Question

我一直收到以下错误：

Missing required parameters for [Route: showtopic] [URI: theme/{id}/topics/{id}].

这就是我的Web.php的样子：

关于web.php中主题的所有内容

Route::get('/theme/{id}/topics/{id}', 'TopicsController@show')->name('showtopic');

Route::get('/theme/{id}/topics/{id}/edit', 'TopicsController@edit')->name('edittopic');
Route::patch('/theme/{id}/topics/{id}/edit', 'TopicsController@update')->name('updatetopic');

Route::get('/theme/{id}/topics/create', 'TopicsController@create')->name('createtopic');
Route::post('/theme/{id}/topics/create', 'TopicsController@save')->name('savetopic');

Route::delete('/theme/{id}/topics/{id}/delete', 'TopicsController@destroy')->name('deletetopic');

关于web.php中主题的所有内容

Route::get('/theme/{id}/topics', 'ThemesController@show')->name('showtheme');

Route::get('/theme/{id}/edit', 'ThemesController@edit')->name('edittheme');
Route::patch('/theme/{id}/edit', 'ThemesController@update')->name('updatetheme');

Route::get('/theme/create', 'ThemesController@create')->name('createtheme');
Route::post('/theme/create', 'ThemesController@save')->name('savetheme');

Route::delete('/theme/{id}/delete', 'ThemesController@destroy')->name('deletetheme');

我在这个问题上提出了关于这个主题的每条路线。所以当我点击我视图中的链接时：

<a href="{{ route('showtopic', ['id' => $topic->id]) }}"

我一直收到我在这个问题开头所显示的错误我希望我明白这一点，让你明白。如果我错过了这个问题所需的信息，请通知我。提前致谢

Answer 1

您必须为路线参数指定两个不同的参数名称

Route::get('/theme/{theme-id}/topics/{topic-id}', 'TopicsController@show')->name('showtopic');

然后将两个参数传递为

{{ route('showtopic', ['theme-id' => $theme->id, 'topic-id' => $topic->id]) }}

如果您只想使用一个参数调用路线，请在路线中将第二个参数作为选项

Route::get('/theme/{theme-id}/topics/{topic-id?}', 'TopicsController@show')->name('showtopic');

然后将两个参数传递为

{{ route('showtopic', ['theme-id' => $theme->id]) }}

Answer 2

要使用route()帮助程序，请将id重命名为：

Route::get('/theme/{themeId}/topics/{topicId}', 'TopicsController@show')->name('showtopic');

因为这条路线有两个参数，你需要传递两个参数：

{{ route('showtopic', ['themeId' => $theme->id, 'topicId' => $topic->id]) }}

Laravel 5.2缺少[Route：showtopic]所需的参数[URI：theme / {id} / topics / {id}]
