How to make relationship between two models and update the database - php

Question

It's me again but now I need some more help from you, I have some version of shopping cart and the whole idea is when I click on the product button the database to be update with the informations which user(id) has order that product(id). First I make orders table with informations(id, product_name, price), other table is users table (id, user_name) and the final table user_order table(id, user_id, order_id);
After that I make two models, one is the Orders model for the products and the second one is the User model. The relationship that I want to make is between this two models.
User model function:
public function orders(){
return $this->belongsToMany('App\Orders', 'user_order', 'user_id', 'order_id');
// return $this->belongsToMany('App\Orders');
}
Orders model function:
public function users(){
return $this->belongsToMany('App\User', 'user_order', 'order_id', 'user_id');
//return $this->belongsToMany('App\User');
}
This is the main html where I show all products with the submit button:
<div class="row">
#foreach($orders as $order)
<div class="col-sm-4 col-lg-4 col-md-4">
<div class="thumbnail">
<img src="http://placehold.it/320x150" alt="">
<div class="caption">
<h4 class="pull-right">{{ $order->cena }}</h4>
<h4>{{ $order->order_name }}
</h4>

</p>
</div>
<div class="btn-group center">
Order this product!
</div>
<br>
</div>
</div>
#endforeach
Controller function:
public function makeOrder(Request $request, $id){
$user = User::where('email', $request['email'])->first();
$findorder = Orders::find($id);
//$user->orders()->detach();
$user->orders()->attach(Orders::where('id', $findorder))->first();
return redirect()->back();
}
And the route:
Route::get('/add-to-database/{id}',[
'uses' => 'AppController#makeOrder',
'as' => 'product.makeOrder'
]);
The whole idea is how to make function after submiting the button the table user_order to be updated with the id of the user, and id of the product.
Any help?

Answer 1

Your makeOrder() should be as:
public function makeOrder(Request $request, $id) {
$user = User::where('email', $request->get('email'))->first();
// this is to make sure that order is available in database
$order = Orders::findOrFail($id);
$user->orders()->attach($order->id);
return redirect()->back();
}
