Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');
Route::post('booking','BookingController@store')->name('booking.store');

Event.php Model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Event extends Model
{
    use HasFactory;

    public function user(){
	     return $this->belongsTo('App\Models\User', 'user_id');
    }
}

Booking.php Model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Booking extends Model
{
    use HasFactory;

    public function client(){
	     return $this->belongsTo('App\Models\User', 'client_id');
    }

    public function approval(){
	    return $this->belongsTo('App\Models\User', 'approval_id');
    }

    public function event(){
      return $this->belongsTo('App\Models\Event');
    }
}

On my event-details.blade.php file, i have a form for booking eg. <form action="{{ route('booking.store') }}" method="post"> and what i want is that, when i click on the booking form, my code should insert user_id, event_id automatically. Any help on how to write my booking code in my BookingCotroller?
