Answer 1

How to do via Controller

1- Set a Rought:
Route::get('foreignkeyforimg', "foreignkey@index"); 2- Create controller With Foreignkey Name.
3- Foreignkey Controller with extend from Migration class.
4- Go to database and delete old primary key manually from the table

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class Foreignkey extends Migration
{
    function index(){

        Schema::table('images', function (Blueprint $table) {


            $table->foreign('sub_cat_id')
               ->references('id')
                ->on('subcategories')
                ->onDelete('cascade');
        });
    }
}
