删除属于帖子的文件？

Question

我有两张名为'posts'和'photos'的表格。 “照片”表格存储“帖子”的图片。一篇文章可以有很多照片，所以这种关系是一对多的。我已经设法创建商店方法，我已经创建了视图以显示其照片的帖子。下面是函数：

public function show($titleslug) { 
     $post = Post::where('titleslug', '=', $titleslug)->first(); 
     $images = $post->photos; 
     return view('dashboard/posts/show', compact('post','images', $post, $images)); 
} 

显示视图：

<div class="contentpanel"> 
    <div class="row blog-content"> 
     <div class="col-sm-12"> 
      <div class="panel panel-default panel-blog"> 
       <div class="panel-body"> 
        <div class="panel-body"> 
         <h3 class="blogsingle-title">{{$post->title}}</h3> 
         <ul class="blog-meta"> 
          <li><i class="fa fa-clock-o"></i> Jan 02, 2014</li> 
         </ul> 
         <div class="mb20"></div> 
         {!! $post->content !!} 
        </div><!-- panel-body -->

        <div class="mb20"></div> 
        <?php foreach ($images as $i): ?> 
         <div class="col-xs-12 col-sm-4 col-md-3"> 
          <div class="blog-item">

我希望能够删除从展会查看图像，如何做到这一点？我需要为它创建一个函数吗？如果是这样，那么函数将如何？ 这一切和感谢，对不起，问太多

Answer 1

首先，通过添加编辑视图您delete form：

... 
<input type="hidden" name="image_id" value="{{ $images->id }}" /> // Assuming that photo id is in your $images object 
... 

然后，你可以从你的controller创建关联到delete功能POST路线image/delete删除预期的图像：

public function delete() { 
    $image_id = $request->only('image_id'); 

    $image = Photo::where('id', '=', $image_id)->delete(); // Assuming that you have a Photo model 

    return view('dashboard/posts/show'); 
}
