Updating Database Record

at the our Controller (BlogController.php) we need add some function, that is "edit function" dan "update function"

Edit Function

public function edit($id)
    {
        // edit function here
        $blog = Blog::find($id);

        // return to 404 page
        if(!$blog){
          abort(404);
        }
        // display the article to single page
        return view('blog.edit')->with('blog',$blog);
    }

Update Function

public function update(Request $request, $id)
    {
      // we will create validation function here
      $this->validate($request,[
          'title'=> 'required',
          'description' => 'required',
      ]);

      $blog = Blog::find($id);
      $blog->title = $request->title;
      $blog->description = $request->description;
      // save all data
      $blog->save();
      //redirect page after save data
      return redirect('blog')->with('message','data hasbeen edited!');
    }

Next, add new views in the \resources\views\blog folder (edit.blade.php)

edit.blade.php

<h2>Edit Article Post</h2>
<form class="" action="/blog/{{ $blog->id }}" method="post">
  <input type="text" name="title" value="{{ $blog->title }}" placeholder="this is title"><br>
  {{ ($errors->has('title')) ? $errors->first('title') : '' }} <br>

  <textarea name="description" rows="8" cols="40" placeholder="this is description">{{ $blog->description }}</textarea><br>
  {{ ($errors->has('description')) ? $errors->first('description') : '' }} <br>

  <input type="hidden" name="_method" value="put">
  <input type="hidden" name="_token" value="{{ csrf_token() }}">
  <input type="submit" name="name" value="edit">
</form>

Next, to create a link to the edit pages, we need update our Index page (index.blade.php)

index.blade.php

{{ Session::get('message') }}

<h1>My First Blog</h1>
@foreach ($blogs as $blog)
  <h2><a href="/blog/{{ $blog->id }}">{{ $blog->title }}</a></h2>
  <p>{{ $blog->description }}</p>
  <a href="/blog/{{ $blog->id }}/edit">Edit this Post</a>
  <hr>
@endforeach
