@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row">

        <div class="col-md-10 offset-2">
            <div class="panel panel-default">
                <h2>Change password</h2>

                <div class="panel-body">
                    @if (session('error'))
                        <div class="alert alert-danger">
                            {{ session('error') }}
                        </div>
                    @endif
                    @if (session('success'))
                        <div class="alert alert-success">

Now, the user is logged in, and if you go to devnote.in/change-password then you should display the below page.

Create Controller

I create new HomeController and add the supporting controller method show_change_password_form in Controller. But you are free to put it in any other controller or create a separate controller for the change-password functionality. And we can make sure that only authenticated users can access the change password functionality.

Post Change Password Request

1. We check the following things.
2. The current password and the new password should not be same.
3. Current password provided by user it should match in the database. And we check this by
4. using Hash::check method.
5. New password Validate requirements, new password and confirm password should be same.
6. Change the password for the user account and redirect back with the success message.

<?php

#app\Http\Controllers\HomeController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\User;
use Hash;
use Auth;

class HomeController extends Controller
{
    public function showChangePasswordGet() {
        return view('auth.passwords.change-password');
    }

    public function changePasswordPost(Request $request) {
        if (!(Hash::check($request->get('current-password'), Auth::user()->password))) {
            // The passwords matches
            return redirect()->back()->with("error","Your current password does not matches with the password.");
        }

        if(strcmp($request->get('current-password'), $request->get('new-password')) == 0){
            // Current password and new password same
            return redirect()->back()->with("error","New Password cannot be same as your current password.");
        }

        $validatedData = $request->validate([
            'current-password' => 'required',
            'new-password' => 'required|string|min:8|confirmed',
        ]);

        //Change Password
        $user = Auth::user();
        $user->password = bcrypt($request->get('new-password'));
        $user->save();

        return redirect()->back()->with("success","Password successfully changed!");
    }
}

 

Add routes

Add the below code into your route file.

 

#routes/web.php

Route::get('/changePassword', [App\Http\Controllers\HomeController::class, 'showChangePasswordGet'])->name('changePasswordGet');
Route::post('/changePassword', [App\Http\Controllers\HomeController::class, 'changePasswordPost'])->name('changePasswordPost');

===== OR Authentication check =====

Route::group(['middleware' => 'auth'], function() {
    Route::get('/changePassword',[App\Http\Controllers\HomeController::class, 'showChangePasswordGet'])->name('changePasswordGet');
    Route::post('/changePassword',[App\Http\Controllers\HomeController::class, 'changePasswordPost'])->name('changePasswordPost');
});

 

Add link

We are looking to include the change Password link in the username top corner right side in the navigation bar. Include the below snippet in your resources/views/layouts/app.blade.php file:

 

#resources/views/layouts/app.blade.php

<div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">
    <a class="dropdown-item" href="{{ route('logout') }}"
        onclick="event.preventDefault();
                        document.getElementById('logout-form').submit();">
        {{ __('Logout') }}
    </a>
    <!-- Change password -->
    <a class="dropdown-item" href="{{ route('changePasswordGet') }}">Change Password </a>

    <form id="logout-form" action="{{ route('logout') }}" method="POST" class="d-none">
        @csrf
    </form>
</div>
