how to create a query with multiple tables in laravel - php

Question

i want to create a query with multiple tables
the query that i need is:
SELECT orders.user_id, orderitem.product_id, orderitem.orderItem_quantity, product.product_price, product.product_imgPath,product.product_name
FROM orderitem, orders, product, users
WHERE orders.user_id = '$_Session[user_id]'
AND orderitem.product_id = product.product_id
AND orderitem.order_id = orders.order_id
AND orders.order_status = 1
and i try these codes:
1:
$cartProducts = DB::table('orderitem')
->join('product','product.product_id','=','orderitem.product_id')
->join('orders','orders.order_id','=','orderitem.order_id')
->where('orders.order_status','=','Waiting')
->where('orders.user_id','=',$userId)
->select('orderitem.*','orders.*','product.*','users.*')
->get();
The error that i get is:
SQLSTATE[42S02]: Base table or view not found: 1051 Unknown table 'users'
2:
$cartProducts = DB::table('orderitem','orders','products','users')

->where('orderitem.product_id','=','product.product_id')
->where('orderitem.order_id','=','orders_id')
->where('order_status','=','Waiting')
->get();
The error that i get is:
SQLSTATE[42S02]: Base table or view not found: 1051 Unknown table 'orders'

Use laravel relationships https://laravel.com/docs/5.5/eloquent-relationships#one-to-many
First, in your User model do:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
public function images()
{
return $this->hasMany('App\Images'); //make sure your images table has user_id column
}
}
And then in your Image table model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Image extends Model
{
public function user()
{
return $this->belongsTo('App\User');
}
}
Now in your controller:
$data = App\Post::user(1)->with('images');
return view('view_name', ["data" => $data]);
Your view:
#foreach($data->images as $image)
<img src="{{ $image->url }}">
#endforeach
