in your controller, you can do it.

$newRow = new YourModelName;
$newRow->column1 = $requesst->value1;
$newRow->column2 = $requesst->value2;
$newRow->column3 = $requesst->value3;
$newRow->column4 = $requesst->value4;
$newRow->save();

these is not what im trying to do

Well,you could use the data coming from the request and do a raw DB query. To see more aboute raw query, check this link https://laravel.com/docs/5.2/queries

An than, perform an alter table on the table you would like. Search for add column table mysql and you will see how to do it.

<?php

namespace App\Http\Controllers;

use Schema;
use Illuminate\Database\Schema\Blueprint;

class DatabaseTableController extends Controller
{
    public function addColumn($sTable, $sColumn)
    {
		Schema::table($sTable, function(Blueprint $table) use ($sColumn, &$fluent)
        {
            $fluent = $table->string($sColumn);
        });

        return response()->json($fluent);     
    }
}

Route:

Route::get('table_add_column/{t}/{c}', 'DatabaseTableController@addColumn');

So URL like this: http://example.com/table_add_column/users/address2 produces:

{"type":"string","name":"address2","length":255}
