How to insert data into multiple table in laravel from single Controller?

Question

[I am new in Laravel]

I am using Laravel 5.5

I have ProductController and model Product also I have two tables products and pcategories . I want to insert data into pcategories table from ProductController . How to do this properly? I have used DB::table('pcategories')-> enter code here insert($data); but it's not inserting created_at and updated_at value.

Another question: Can I call multiple models into a controller?

This is my controller

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use App\Product;
use Image;

class ProductController extends Controller {

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response

        $product->categorieslist = Product::table('pcategories')->get();
        return view('product.add')->with($data);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create() {
        $product->categorieslist = Product::table('pcategories')->get();
        return view('product.add')->with($data);
    }

    public function all() {
        $product->products = Product::table('products')->get();
        return view('product.all', $data);
    }

    /**

Answer 1

Use Eloquent Model instead of Query Builder . Fields created_at , updated_at are "part" of Eloquent . You either use Eloquent or insert manually those fields.

If you want to use Eloquent , then make two model Product and PCategory . And then insert with your model.

PCategory::create($data);

And you need to mass assigned your field on model class.If you don't want to mass assigned your fields, than do like this-

$pcategory = new PCategory();
//$pcategory->column1 = $data['column1'] or $data->column1;
$pcategory->save();

To learn more, follow this official doc.

And for your second part, Yes , You can.

Answer 2

First, create a proper relationship with your models ( one to many, etc. ) Second, you can use the DB::transact to insert data into multiple tables in DB. It has it's own advantages rather than just inserting Fk in tables to fill in the data. For further info you can search in google.
