<?php

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index()
    {
        $users = User::all();
        return view('admin.user.index', compact('users'));
    }

    public function edit($user_id)
    {
        $user = User::find('$user_id');
        return view('admin.user.edit', compact('user'));
    }
}

CodePudding user response：

You are using ' in find section please remove it :

public function edit($user_id)
{
    $user = User::find($user_id);
    return view('admin.user.edit', compact('user'));
}

CodePudding user response：

In your UserController in edit() method you are using single quote (') that is converting your variable as string. After that your model is generating query like below

select * from users where id='user_id'

this is not correct at all. Remove single quote from your find() method inside edit() method. Hope that you will get correct result according to need.

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index()
    {
        $users = User::all();
        return view('admin.user.index', compact('users'));
    }

    public function edit($user_id)
    {
        $user = User::find($user_id'); //removed single quote(') from here
        return view('admin.user.edit', compact('user'));
    }
}
