Question

我试图通过路线传递getMonth视图，但似乎正在工作，因为它在指定$ month时显示我的数据库的所有结果，而不是按月过滤结果。但是$ id确实有用，并且会转到匹配db中的$ id的单个帖子。

Route::get('blog', ['as' => 'blog', 'uses' => 'BlogController@BlogIndex']);
Route::get('blog/{Id}', ['as' => 'blog.id', 'uses' => 'BlogController@ShowbyId']);
Route::get('blog/month/{month}', ['as' => 'blog.month', 'uses' => 'BlogController@ShowbyMonth']);

class BlogController extends BaseController {

 public function BlogIndex()
{
 //get the posts from the database by asking the Active Record for "all"
$blogs = Blog::all();
$blogs = DB::table('blogs')->paginate(3);
// and create a view which we return - note dot syntax to go into folder
return View::make('pages.blog', array('blogs' => $blogs));
}
public function ShowbyId($Id)
{          
   $Ids = Blog::where('Id', '=', $Id)->get();
// show the view with blog posts (app/views/pages/blog.blade.php)
return View::make('pages.blog')
    ->with('Ids', $Ids)      
}
public function ShowbyMonth($month)
{
   $months = Blog::where('month', '=', $month)->get();
// show the view with blog posts (app/views/pages/blog.blade.php)
return View::make('pages.blog')
    ->with('months', $months)     
}
}

blog.blade.php

@if(isset($blogs)) 
@foreach ($blogs as $blog)
  <div class="blog-outer-wrap">
  <img src="images/blog/{{ $blog->img}}"> 
  <div class="blog-header">{{ $blog->header }}</div>
  <div class="blog-text">{{ $blog->content }}</div>
  <a href="{{ URL::route('blog.slug', [$blog->slug]) }}">
  </div>
@endforeach
@elseif(isset($Ids)) 
@foreach ($Ids as $Id)
  <div class="blog-outer-wrap">
  <img src="images/blog/{{ $Id->img}}"> 
  <div class="blog-header">{{ $Id->header }}</div>
  <div class="blog-text">{{ $Id->content }}</div>
  </div>
 @elseif(isset($months))
 @foreach ($months as $month) 
<div class="blog-outer-wrap">
<img src="images/blog/{{ $Month->img}}"> 
 <div class="blog-header">{{ $Month->header }}</div>
<div class="blog-text">{{ $Month->content }}</div>
</div>
@endif
@endforeach

Answer 1

我不确定它是否解决了问题但是在刀片文件中你有：

@elseif(isset($months))
 @foreach ($months as $month) 
<div class="blog-outer-wrap">
<img src="images/blog/{{ $Month->img}}"> 
 <div class="blog-header">{{ $Month->header }}</div>
<div class="blog-text">{{ $Month->content }}</div>
</div>
@endif

应该是：

@elseif(isset($months))
 @foreach ($months as $Month) 
<div class="blog-outer-wrap">
<img src="images/blog/{{ $Month->img}}"> 
 <div class="blog-header">{{ $Month->header }}</div>
<div class="blog-text">{{ $Month->content }}</div>
</div>
@endif

你应该关心变量案例。

我看到的问题是你的URI /路由结构，你现在有这个：

Route::get('blog/{Id}', ['as' => 'blog.id', 'uses' => 'BlogController@ShowbyId']);
Route::get('blog/month/{month}', ['as' => 'blog.month', 'uses' => 'BlogController@ShowbyMonth']);

每当您尝试访问blog.month路由blog.id时，都会收到month字样。将月份路线放在第一位可能会更好，以便在ID路线之前点击月份URI。

Route::get('blog/month/{month}', ['as' => 'blog.month', 'uses' => 'BlogController@ShowbyMonth']);
Route::get('blog/{id}', ['as' => 'blog.id', 'uses' => 'BlogController@ShowbyId']);

此外，要清理控制器，您可以考虑使用查询范围使您的逻辑更可重用且更易于调试。在你的模型中，你可以这样做：

class Blog extends Eloquent {
  public function scopeMonth($query, $month) {
    return $query->where('month', '=', $month);
  }
}

然后在你的控制器中你可以这样做：

class BlogController extends BaseController {

  //.. BlogIndex here

  public function ShowbyId($Id)
  {          
     $blog = Blog::find($id)->get();

    // show the view with blog posts (app/views/pages/blog.blade.php)
    return View::make('pages.blog')
      ->with('Ids', $blog);      
  }

  public function ShowbyMonth($month)
  {
    $months = Blog::month($month)->get();

    // show the view with blog posts (app/views/pages/blog.blade.php)
    return View::make('pages.blog')
      ->with('months', $months)     
  }
}

希望这有帮助！
