How to set condition in Query Builder?

Question

I'm trying to set a condition in my function where I need set my column role_id equal to 1 if it's true it will return me a view. First I retrieve all the column in my users table $result = DB::table('users')->get(); after that I set a if condition.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\User;
use App\Http\Requests;
use DB;

class DocumentController extends Controller
{
    public function getDocuments()
    {
        $result = DB::table('users')->get();


        if ('role_id' == 1)
        {
            return view ('document.create');
        }
    }
}

I tried to set my role_id == 1 but it says.

Use of undefined constant role_id - assumed 'role_id'

Answer 1

try this...

// if you want to fetch only user with role_id = 1
    $users = DB::table('users')->where('role_id', '=', 1)->get();

in your case you can use condition like

if( $users->role_id == 1 )
{

}

如果要检查当前用户，只需使用Auth::user() ：

 if(\Auth::user()->role_id == 1)
