public function my($data)
{
$save = new rahul;
$save->id = $data['id'];

database name is lara2 and table name display simple page design
but problem how to model be used

Answer 1

Route::get('first', 'ApiController#first')->name('first');
Route::post('store', 'ApiController#store')->name('store');
using the code in api.php
and next step model is create
php artisan make: model Article
model page
class Article extends Model{ protected $fillable = ['name', 'email'];}
next step create the controller
controller page (apicontroller)
public function first(){
return view('first');
}
public function store(Request $request)
{
$article = Article::create($request->all());
return response()->json($article, 201);
}
blade page web page design
<form method="POST" action="store">
{{csrf_field()}}
<input type="text" name="name">
<input type="email" name="email">
<input type="submit" name="submit"></form>
migration is create Article table name connection
public function up()
{
Schema::create('Articles', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('Articles');
}
