Introduction

ZfcUser is a user registration and authentication module for Laminas. Out of the box, ZfcUser works with Laminas\Db, however alternative storage adapter modules are available (see below). ZfcUser provides the foundations for adding user authentication and registration to your Laminas site. It is designed to be very simple and easy to extend.

More information and examples are available on the ZfcUser Wiki

Versions

Please use below table to figure out what version of ZfcUser you should use.

ZfcUser version	Supported Zend Framework version	Status
1.x	<= 2.5	Security-fixes only
2.x	>= 2.6 < 3	bug-fixes, security-fixes
3.x	>= 3 / Laminas	New features, bug-fixes, security-fixes

Storage Adapter Modules

By default, ZfcUser ships with support for using Laminas\Db for persisting users. However, by installing an optional alternative storage adapter module, you can take advantage of other methods of persisting users:

ZfcUserDoctrineORM - Doctrine2 ORM
ZfcUserDoctrineMongoODM - Doctrine2 MongoDB ODM

Requirements

Laminas.

Installation

Main Setup

By cloning project

Install the ZfcBase ZF2 module by cloning it into ./vendor/.
Clone this project into your ./vendor/ directory.

With composer

Add this project and ZfcBase in your composer.json:

"require": {  
    "zf-commons/zfc-user": "^3.0"  
}

Now tell composer to download ZfcUser by running the command:
```
$ php composer.phar update
```

Post installation

Enabling it in your application.config.phpfile.

<?php
return array(
    'modules' => array(
        // ...
        'ZfcUser',
    ),
    // ...
);

Then Import the SQL schema located in ./vendor/zf-commons/zfc-user/data/schema.sql (if you installed using the Composer) or in ./vendor/ZfcUser/data/schema.sql.

Post-Install: Doctrine2 ORM

Coming soon...

Post-Install: Doctrine2 MongoDB ODM

Coming soon...

Post-Install: Laminas\Db

If you do not already have a valid Laminas\Db\Adapter\Adapter in your service manager configuration, put the following in ./config/autoload/database.local.php:

<?php
return array(
    'db' => array(
        'driver'    => 'PdoMysql',
        'hostname'  => 'changeme',
        'database'  => 'changeme',
        'username'  => 'changeme',
        'password'  => 'changeme',
    ),
    'service_manager' => array(
        'factories' => array(
            'Laminas\Db\Adapter\Adapter' => 'Laminas\Db\Adapter\AdapterServiceFactory',
        ),
    ),
);

Navigate to http://yourproject/user and you should land on a login page.

Password Security

DO NOT CHANGE THE PASSWORD HASH SETTINGS FROM THEIR DEFAULTS unless A) you have done sufficient research and fully understand exactly what you are changing, AND B) you have a very specific reason to deviate from the default settings.

If you are planning on changing the default password hash settings, please read the following:

The password hash settings may be changed at any time without invalidating existing user accounts. Existing user passwords will be re-hashed automatically on their next successful login.

WARNING: Changing the default password hash settings can cause serious problems such as making your hashed passwords more vulnerable to brute force attacks or making hashing so expensive that login and registration is unacceptably slow for users and produces a large burden on your server(s). The default settings provided are a very reasonable balance between the two, suitable for computing power in 2013.

Options

The ZfcUser module has some options to allow you to quickly customize the basic functionality. After installing ZfcUser, copy ./vendor/zf-commons/zfc-user/config/zfcuser.global.php.dist to ./config/autoload/zfcuser.global.php and change the values as desired.

The following options are available:

user_entity_class - Name of Entity class to use. Useful for using your own entity class instead of the default one provided. Default is ZfcUser\Entity\User.
enable_username - Boolean value, enables username field on the registration form. Default is false.
auth_identity_fields - Array value, specifies which fields a user can use as the 'identity' field when logging in. Acceptable values: username, email.
enable_display_name - Boolean value, enables a display name field on the registration form. Default value is false.
enable_registration - Boolean value, Determines if a user should be allowed to register. Default value is true.
login_after_registration - Boolean value, automatically logs the user in after they successfully register. Default value is false.
use_registration_form_captcha - Boolean value, determines if a captcha should be utilized on the user registration form. Default value is true. (Note, right now this only utilizes a weak Laminas\Text\Figlet CAPTCHA, but I have plans to make all Laminas\Captcha adapters work.)
login_form_timeout - Integer value, specify the timeout for the CSRF security field of the login form in seconds. Default value is 300 seconds.
user_form_timeout - Integer value, specify the timeout for the CSRF security field of the registration form in seconds. Default value is 300 seconds.
use_redirect_parameter_if_present - Boolean value, if a redirect GET parameter is specified, the user will be redirected to the specified URL if authentication is successful (if present, a GET parameter will override the login_redirect_route specified below).
login_redirect_route String value, name of a route in the application which the user will be redirected to after a successful login.
logout_redirect_route String value, name of a route in the application which the user will be redirected to after logging out.
password_cost - This should be an integer between 4 and 31. The number represents the base-2 logarithm of the iteration count used for hashing. Default is 10 (about 10 hashes per second on an i5).
enable_user_state - Boolean value, enable user state usage. Should user's state be used in the registration/login process?
default_user_state - Integer value, default user state upon registration. What state user should have upon registration?
allowed_login_states - Array value, states which are allowing user to login. When user tries to login, is his/her state one of the following? Include null if you want user's with no state to login as well.

Note: user_login_widget_view_template is currently not used. To override the view templates the module uses, please see this example.

Changing Registration Captcha Element

NOTICE These instructions are currently out of date.

By default, the user registration uses the Figlet captcha engine. This is because it's the only one that doesn't require API keys. It's possible to change out the captcha engine with DI. For example, to change to Recaptcha, you would add this to one of your configuration files (global.config.php, module.config.php, or a dedicated recaptcha.config.php):

<?php
// ./config/autoload/recaptcha.config.php
return array(
    'di'=> array(
        'instance'=>array(
            'alias'=>array(
                // OTHER ELEMENTS....
                'recaptcha_element' => 'Laminas\Form\Element\Captcha',
            ),
            'recaptcha_element' => array(
                'parameters' => array(
                    'spec' => 'captcha',
                    'options'=>array(
                        'label'      => '',
                        'required'   => true,
                        'order'      => 500,
                        'captcha'    => array(
                            'captcha' => 'ReCaptcha',
                            'privkey' => RECAPTCHA_PRIVATE_KEY,
                            'pubkey'  => RECAPTCHA_PUBLIC_KEY,
                        ),
                    ),
                ),
            ),
            'ZfcUser\Form\Register' => array(
                'parameters' => array(
                    'captcha_element'=>'recaptcha_element',
                ),
            ),
        ),
    ),
);
