$student = new User();
$student->email =$email;
$student->name = $name;
$student->branch = $branch;
$student->course_name = $course_name;
$student->save();
return redirect()->back();
}
}
Route/web.php:
Route::group(['middleware' => ['web']], function(){
Route::get('/', function () {
return view('welcome');
});
Route::post('/submit_data',[
'uses' => 'UserController#postData',
'as' => 'submit_data'
]);
});
Migration:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('students', function (Blueprint $table) {
$table->increments('id');
$table->string('mail')->unique();
$table -> string('name');
$table -> string('branch');
$table -> string('course_name');
$table->rememberToken();
$table->timestamps();
});
}
public function down()
{
Schema::drop('students');
}
}
My migration's name is create_users_table. I don't understnad why this error is coming. It's an easy and simple form.Just a simple form to submit a students data, and save it in database.

Answer 1

You are posting to a get route
In your welcome.blade.php you forgot to set your action, so by default it will try to post to the same page / which is definded as a get route in your routes/web.php. Set the action to /submit_data like so in your welcome.blade.php:
<form action="{{ url('/submit_data') }}" method="post">

Answer 2

<form action="{{ url('submit_data') }}" method="post">

Answer 3

you can also use blade from like this
{{Form::open(array('url'=>'/submit_data','files'=>true,'class'=>'form-horizontal','file'=>'true'))}}
