couldn't filter request through middleware - database

Question

I am trying to filter my http request by using middleware.
I want to check if the "friends_id" that i am getting from http request and "my_id" that I am passing in through Auth already don't exists in the same row, If they do I wanna redirect to home page and if they don't I wanna execute the normal request which will eventually insert the data that I am checking for
The error is "Trying to get property 'friends_id' of non-object "
Here's my "Friends" middleware:-
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
class Friends
{
public function handle($request, Closure $next)
{ $auth = Auth()->user()->id;
$dost = $request->friends_id;
$ip = DB::table('friends')
->where('my_id', '=', $auth)
->where('friends_id', '=', $dost)
->get();
if($ip->friends_id != $dost){
return $next($request);
}
return redirect('/home');
}
}
Here's my friends Table:-
public function up()
{
Schema::create('friends', function (Blueprint $table) {
$table->id();
$table->string('my_id');
$table->string('friends_id');
$table->string('name');
$table->timestamps();
});
}
This is my Route:-
Route::post('/f', 'FriendsController#store')->middleware('friends');
-ThankYou

Answer 1

Try this
your query will be wrong use where instead of whereColumn and when you get first record use only first() not get()
use DB;
$ip = DB::table('friends')
->select('my_id', 'friends_id')
->where([['my_id', '=', '$auth'],['friends_id', '=', '$dost']])
->first();
EDIT
public function handle($request, Closure $next)
{
$auth = Auth()->user()->id;
$dost = $request->friends_id;
$ip = DB::table('friends')
->select('my_id', 'friends_id')
->where([['my_id', '=', '$auth'],['friends_id', '=', '$dost']])
->first();
if($ip->friends_id == $dost){
return redirect('/home');
} else {
return $next($request);
}
}

The Solution is:-
Friends Middleware:-
public function handle($request, Closure $next)
{
if (auth()->check()) {
$ip = DB::table('friends')->where('my_id', '=', auth()->id())->where('friends_id', '=', $request->friends_id)->first();
if ($ip && $ip->friends_id == $request->friends_id) {
return redirect('/home');
}
}
return $next($request);
}
}
