how to get the products that have the incategory_id passed with the url ?

Answer 1

You could use the Request facade to get the id and then, use the where method to get the requested product like this:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Request;
use DB;
class productController extends Controller
{
public function getIndex()
{
$in=Request::get('id');
$product=DB::table('products')->where('incategory_id', $in)->get(['id','name','salary','sale','p_salary','n_salary','best','type','image_name','category_id','sub_id','incategory_id','new']);
return view('contents.products')->with('product',$product);
}
}
Also, you could type-hint the Illuminate\Http\Request:
public function getIndex(Request $request)
{
$in=$request->get('id');
// ...
}
