README

A tool for easy public token implementation in some common tasks: password reset, account activation, etc. In general, when need to send a token through mail (for example). We are developed with Laravel 5.x in mind.

Installation

Add in your composer.json:

{
    "require": {
        "malahierba-lab/token": "~1.0"
    }
}

Then you need run the composer update command.

How Work

The tokens are save using Laravel Cache Facade, so you don't need a table in your database (unless you are using the database cache as driver), so... you don't need alter your current database, and tokens expire automatically without headaches :)

Use

Important: For documentation purposes, in the examples below, always we assume than you import the library into your namespace using use Malahierba\Token\Token;

You can generate a token for any model (Eloquent/Model) in your project. In this examples below we are using the User Model, but you can use the Model than you need.

1.- Make a Token Instance

//Get a Model Instance... in this case, a User instance.
$user = User::find(1);

// Create a password reset token instance
// 'password reset' is just a example... you can use the string than you want :)
// so.. if you want a token named 'my token type' just use it as second parameter. No predefined types.
$token = new Token($user, 'password reset');

//You can define the duration, in minutes, until the token expire. Default is 60.
//This example set 15 minutes to expire the token
$token = new Token($user, 'password reset', 15);

//Also you can define the number of chars for token. Default is 48
//This example set token length in 32 chars (and use the default minutes to expire)
$token = new Token($user, 'password reset', null, 32);

//This example set 15 minutes to expire the token and token length in 32 chars
$token = new Token($user, 'password reset', 15, 32);

2.- Get the Token string

$token_str = $token->get();

If no previous token exists (or previous token is expired), then you will get a new randomly generated string. If previous token exists (and is not expired yet) then you get that token.

3.- Check the Token

You can validate a token entered by an user or when come from url (for example if you mail a link for password reset with the token as parameter):

if ($token->check($string))
    // code for token validated

4.- Delete the Token

When you don't need the token anymore (for example, your user already setup a new password in password reset lifecycle) you can delete it:

$token->delete();

The delete method no destroy the token instance, just delete the old token string. If you run $token->get() you will receive a new token for same user (and same type) because the instance is the same.
