After entering this is Command It takes some time depends on your internet speed. After creating a new Laravel Project Now move to the First Step.

Insert Data Into database in laravel 5.6

Step 1: Create a Model, Controller, and Migration

We Need Model, Migration, and Controller to Start CRUD operation in Laravel  5.6. First, go to the Project path and enter the Following Command in CMD.

php artisan make:model Blog -mcr

After that its generate 3 new files.

app-> Blog.php.

database->migrations-> create_blogs_table.php

app->http->controller-> BlogController.php.

Step 2: Create a Database Table

Open create_blogs_table.php and add some column title and body as follows.

public function up()
{
  Schema::create('blogs', function (Blueprint $table) {
         $table->increments('id');
         $table->string('title');
         $table->string('body');
         $table->timestamps();
        });
}

Before the migration, you should connect with your database. so open your .env file and add database, username and password field. (In my case my database name is "new blog" username is "root" and password is blank )

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=newblog
DB_USERNAME=root
DB_PASSWORD=

Now open CMD and enter a Command to migrate.

php artisan migrate

if you got some error like follows If not go to Step 3

In Connection.php line 647:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQ
  L: alter table `users` add unique `users_email_unique`(`email`))


In Connection.php line 449:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

Edit your app->providers->AppServiceProvider.php file 

use Illuminate\Support\Facades\Schema;

public function boot()
{
    Schema::defaultStringLength(191);
}

Step 3: Create a form

Create a View Page For insert into the database.

{!! Form::open(array('route' => 'blog.store', 'method'=>'post')) !!}
<div class="container">
<div class="row">
<div class="col-md-12">
  <form>
   <div class="form-group">
     <label for="exampleInputEmail1">Title</label>
     <input type="text" class="form-control" name="title" placeholder="Enter title">
   </div>
     
   <div class="form-group">
      <label for="exampleFormControlTextarea1">Blog Body</label>
      <textarea class="form-control" name="body"rows="3"></textarea>
   </div>

   <button type="submit" class="btn btn-primary">Submit</button>
    </form>
 {!! Form::close() !!}
</div>
</div>
</div>

After adding this is code may be Show Error "Class 'form' not found" so go to this link 

Now Open BlogController.php and Edit

public function store(Request $request)
    {
      $this->validate($request,array(
       'title'       => 'required|max:255',
       'body'         =>'required',
     ));
     $blog = new Blog;
     $blog->title = $request->title;
     $blog->body=$request->body;
     $blog->save();

    }
