Select * from a pivot table in laravel - php

Question

I have a many to many relation with table users,items and the pivot table user_item and i need to call the query : Select * from user_item where user_id=$user->id in laravel and return the results in json format. I try with
$user=User::find(session('user_id'))->items()->get();
return response ()->json($user);
But it doesn't work. How can I do that?
class User extends Authenticatable {
public function items (){
return $this->belongsToMany ("App\Models\Item", "user_item", "user", "item");
}
}
class Item extends Models {
public function users (){
return $this->belongsToMany ("App\Models\User", "user_item", "item", "user");
}
}

Answer 1

You can define columns in your pivote table using withpivot method
public function items (){
return $this->belongsToMany ("App\Models\Item", "user_item",
"user", "item")->withPivot(['column1', 'column2','another_column']);
}
to get relation instead of using get(), you should use like below:
$user=User::find(session('user_id'))->items;
return response ()->json($user);
above will give below json result:
[{
"id": 4,
"name": "PC",
"pivot": {
"column1": 1,
"column2": 4,
"another_column": "2016-03-03"
}
},
{
"id": 5,
"name": "Phone",
"pivot": {
"column1": 1,
"column2": 4,
"another_column": "2016-03-03"
}
}]
you can also include pivot in use user model using with():
$user=User::with('items')->find(session('user_id'));
return response ()->json($user);
give json result something like:
{
"id": 1,
"name": "User Name",
"email": "email#user.com",
"created_at": null,
"updated_at": null,
"items": [{
"id": 4,
"name": "PC",
"pivot": {
"column1": 1,
"column2": 4,
"another_column": "2016-03-03"
}
},
{
"id": 5,
"name": "Phone",
"pivot": {
"column1": 1,
"column2": 4,
"another_column": "2016-03-03"
}
}]
}]
