如何在Laravel博客应用中的刀片模板视图中登录用户显示帖子是否有书签？

Question

I'm currently working on Laravel blog App. I want to display posts is bookmarked by loggedin user or not on blade template view .

On Click of post's bookmark button , Im calling ajax function and that is working correctly.

but when i request to page /posts it shows all posts with same color bookmarks

but not showing bookmarked posts bookmark button with red color

i want to distinguish post on page render if it is bookmared by logged in user or not .

I have 3 tables in mysql database : users, posts, bookmarks table

structure users table : (id,name,email,password,...)

structure posts table : (id,title,body,user_id, ...)

structure bookmarks table : (user_id,post_id,created_at,updated_at)

here is code for showing bookmark icon in blade view

    <span class="desktop-post-read-later">                                                          
        @if(Auth::guest())

          <span class="post-read-later" data-type="add" data-id="{{$post->id}}" title="Please login to bookmark this post!">
               <i class="bookmark fa fa-bookmark-o" id="bookmark_{{$post->id}}"></i>
          </span>

        @else
         <span class="post-read-later" data-type="add" data-id="{{$post->id}}">

          @if( ?????   what condition here i have to put ??????)

          <i class="bookmark fa fa-bookmark-o" id="bookmark_{{$post->id}}" style="color:red"></i>

          @else
          <i class="bookmark fa fa-bookmark-o" id="bookmark_{{$post->id}}"></i>
          @endif 
        </span> 
  @endif                                                          

Answer 1

I have got my answer , by adding following method on my PostsController

function get_user_bookmark_postids(){
    $postsids=[];
    if(Auth::check()){
        $data = DB::table('posts')
        ->join('bookmarks', 'posts.id', '=', 'bookmarks.post_id')
        ->where('bookmarks.user_id', '=',Auth::user()->id)
        ->select('posts.id')
        ->get();
        $plucked = $data->pluck('id');
        $postsids=$plucked->all();
        return $postsids;
    }else{
        $postsids=[];
    }
}

 public function index()
{   
    $bookmarked_posts=$this->get_user_bookmark_postids();
    return view('user.posts.index',compact('bookmarked_posts'));   
}

and on blade view

<span class="desktop-post-read-later">
       @if(Auth::guest())
           <span class="post-read-later" data-type="add" data-id="{{$post->id}}" title="Please login to bookmark this post!">
           <i class="fa fa-bookmark-o"></i>
           </span>

        @else

         <span class="post-read-later" data-type="add" data-id="{{$post->id}}">                                                 
         @if(in_array($post->id,$bookmarked_posts))
         <i class="bookmark fa fa-bookmark-o" id="bookmark_{{$post->id}}" style="color:red"></i>
         @else 

         <i class="bookmark fa fa-bookmark-o" id="bookmark_{{$post->id}}"></i>
         @endif 
         </span> 
      @endif   
</span>
