How to validate current, new, and new password confirmation in Laravel 5?

Question

I have created the password route, view and method in UserController@getProfilePassword and UserController@postProfilePassword

At the moment, if I fill out the new_password field, it gets hashed and submitted to the database correctly, then I can login with the new password.

But I need to be able to validate the new_password and new_password_confirm to make sure they're the same and validate the user's current password as well.

How can I do that?

EDIT: I added $this->validate to the method, but now I keep getting the error The password confirmation confirmation does not match. even though they do match as I am using a simple password. Also I think I need to check against the current password manually as validator won't do it for me.

public function getProfilePassword(Request $request) {
    return view('profile/password', ['user' => Auth::user()]);
}

public function postProfilePassword(Request $request) {
    $user = Auth::user();

    $this->validate($request, [
        'old_password'          => 'required',
        'password'              => 'required|min:4',
        'password_confirmation' => 'required|confirmed'
    ]);

    $user->password = Hash::make(Input::get('new_password'));
    $user->save();
}

And this is the view

<form action="{{ route('profile/updatepassword') }}" method="post" enctype="multipart/form-data">
    <div class="form-group">
          <label for="name">Current Password</label>
          <input type="password" name="old_password" class="form-control" id="old_password">
    </div>
    <div class="form-group">
          <label for="name">Password</label>
          <input type="password" name="password" class="form-control" id="password">
    </div>
    <div class="form-group">
          <label for="name">New Password</label>
          <input type="password" name="password_confirmation" class="form-control" id="password_confirmation">
    </div>
    <button type="submit" class="btn btn-primary">Change Password</button>
    <input type="hidden" value="{{ Session::token() }}" name="_token">
 </form>

Answer 1

There's a Hash::check() function which allows you to check whether the old password entered by user is correct or not.

usage

if (Hash::check("param1", "param2")) {
 //add logic here
}

param1 - user password that has been entered on the form
param2 - old password hash stored in database

it will return true if old password has been entered correctly and you can add your logic accordingly

for new_password and new_confirm_password to be same, you can add your validation in form request like

'new_password' => 'required',
'new_confirm_password' => 'required|same:new_password'

Answer 2

If you only need the functionality of a custom rule once throughout your application, you may use a Closure instead of a rule object. The Closure receives the attribute's name, the attribute's value, and a $fail callback that should be called if validation fails

$request->validate([
    'new_password' => 'required|confirmed|min:4',
    'current_password' => ['required', function ($attribute, $value, $fail) use ($user) {
        if (!\Hash::check($value, $user->password)) {
            return $fail(__('The current password is incorrect.'));
        }
    }],
]);

In Laravel 6 there is a new rule called password ,according to docs

The field under validation must match the authenticated user's password. You may specify an authentication guard using the rule's first parameter:
'password' => 'password:api'

so the validation rules can be as simple as :

'current_password' => 'required|password',
'password' => 'required|string|min:8|confirmed',

Answer 4

You can do this by creating a custom validation rule (for this example I'm using current_password and new_password as the input names).

Put this in AppServiceProvider::boot():

Validator::extend('current_password', function ($attribute, $value, $parameters, $validator) {
    $user = User::find($parameters[0]);

    return $user && Hash::check($value, $user->password);
});

Now you can use the following in your controller:

$user = auth()->user(); // or pass an actual user here

$this->validate($request, [
    'current_password' => 'required_with:new_password|current_password,'.$user->id,
]);

Using laravel 5.8/6.0, here is what i do(without much additional code)

Step 1: Validate

    $data = request()->validate([
        'firstname' => ['required', 'string', 'max:255'],
        'lastname' => ['required', 'string', 'max:255'],
        'username' => ['bail', 'nullable', 'string', 'max:255', 'unique:users'],
        'email' => ['bail', 'nullable', 'string', 'email:rfc,strict,dns,spoof,filter', 'max:255', 'unique:users'],
        'new_password' => ['nullable', 'string', 'min:8'],
        'confirm_new_password' => ['nullable', 'required_with:new_password', 'same:new_password'],
        'current_password' => ['required', function ($attribute, $value, $fail) {
            if (!\Hash::check($value, Auth::user()->password)) {
                return $fail(__('The current password is incorrect.'));
            }
        }]
    ]);

Step 2: If validation is passed

1. Create array , checking each input value (but not the ones with the required tag in validation) for presence or null OR do something that you want.

For example:

if(request(input)){
    $data += ['input' => request(input)];
}

2. Update database using the created array

For example:

Auth::user()->account->update($data);
