How can i update post with old tags and new tags in laravel 8?

Time:10-03

When I want to edit the post with the post's existing tags it only shows one tag though there are more tags in the selected post. I also want to input new tags in the post-editing blade.

Post creating code

           //Store Post
            public function storeNewPost(Request $request){
                //return $request->all();
                $request->validate([
                    'post_title' => 'required',
                    'post_details' => 'required',
                    'category_id' => 'required',
                    'image' => 'image|max:15360|dimensions:max_width=4000,max_height=3000'
                ]);

                $image = $request->file('post_thumbnail');
                
                $name_gen=uniqid().'.'.$image->getClientOriginalExtension();
                Image::make($image)->resize(700,400)->save('frontend/assets/images/post/'.$name_gen);
                $save_url = 'frontend/assets/images/post/'.$name_gen;

                $post = Post::create([

** post editing blade's tags code **

         <div class="form-group">

             @foreach ($editPost->tags as $tags) value="{{$tags->name}}" @endforeach>
                                                    
       </div>

If you have manyToMany relation in your models use sync() method on update method.

Example: $post->tags()->sync($request->tags);

CodePudding user response:

 // try this 
 <input type="text" class="w-100" id="tagnames" name="tags[]" data-role="tagsinput"  value="@foreach($editPost->tags as $tags){{$tags->name.','}}@endforeach">
