Introduction
------------

This Bundle use [Mobile_Detect](https://github.com/serbanghita/Mobile-Detect) class and provides the following features:

* Detect the various mobile devices by Name, OS, browser User-Agent
* Manages site views for the variuos mobile devices (`mobile`, `tablet`, `full`)
* Redirects to mobile and tablet sites


Switch device view
------------------

For switch device view, use `device_view` GET parameter:

````
http://site.com?device_view={full/mobile/tablet}
````

Installation
------------

### Composer

Add to `composer.json` in your project to `require` section:

```json
{
    "suncat/mobile-detect-bundle": "0.10.*"
}
```

Run command:
`php composer.phar install`

### Add this bundle to your application's kernel

```php
//app/AppKernel.php
public function registerBundles()
{
    return array(
         // ...
        new SunCat\MobileDetectBundle\MobileDetectBundle(),
        // ...
    );
}
```
### Conﬁgure service in your YAML conﬁguration
```yaml
#app/conﬁg/conﬁg.yml
mobile_detect:
    redirect:
        mobile: ~
        tablet: ~
    switch_device_view: ~
```

### Full conﬁguration

You can change default behaviour of your redirects with action parameter:

- `redirect`: redirects to appropriate host with your current path
- `no_redirect`: no redirection (default behaviour)
- `redirect_without_path`: redirects to appropriate host index page

```yaml
#app/conﬁg/conﬁg.yml
mobile_detect:
    redirect:
        full:
            is_enabled: true            # default false
            host: http://site.com       # with scheme (http|https), default null, url validate
            status_code: 301            # default 302
            action: redirect            # redirect, no_redirect, redirect_without_path
        mobile:
            is_enabled: true            # default false
            host: http://m.site.com     # with scheme (http|https), default null, url validate
            status_code: 301            # default 302
            action: redirect            # redirect, no_redirect, redirect_without_path
        tablet:
            is_enabled: true            # default false
            host: http://t.site.com     # with scheme (http|https), default null, url validate
            status_code: 301            # default 302
            action: redirect            # redirect, no_redirect, redirect_without_path
        detect_tablet_as_mobile: true   # default false
    switch_device_view:
        save_referer_path: false        # default true
                                        # true  redirectUrl = http://site.com/current/path?currentQuery=string
                                        # false redirectUrl = http://site.com
    service:
        mobile_detector: mobile_detect.mobile_detector.default
    device_view_class: SunCat\MobileDetectBundle\Helper\DeviceView
    request_listener_class: SunCat\MobileDetectBundle\EventListener\RequestListener
    extension_class: SunCat\MobileDetectBundle\Twig\Extension\MobileDetectExtension
```

You can also create route specific rules for redirecting in your routing.yml.
Just put appropriate platform to options field and add it redirecting rule.

```yaml
#routing.yml
someaction:
    pattern:  /someaction
    defaults: { _controller: YourBundle:Index:someaction }
    options:  { mobile: redirect, tablet: no_redirect, full: redirect_without_path }         # redirect, no_redirect, redirect_without_path
```

Usage Example:
--------------

#### Setting up redirection to and from a mobile site that is the same Symfony 2 instance as your main site.

In this example, let's assume that you have a website http://site.com and you wish to activate
redirection to a mobile site http://m.site.com when the user is using a mobile device.

Additionally, when a user with a desktop browser reaches the mobile site http://m.site.com, he
should be redirected to the full version at http://site.com.

1. **Set up mobile redirection to your config.yml**

    ```yaml
    mobile_detect:
        redirect:
            mobile:
                is_enabled: true
                host: http://m.site.com
                status_code: 301
                action: redirect
            tablet: ~
        switch_device_view: ~
    ```

    Now when you hit http://site.com with a mobile device, you are redirected to http://m.site.com.
    At this point if the http://m.site.com is configured to point to your project, you will get circular reference error.
    To get rid of the circular reference error, we want to disable mobile redirecting when we land on our mobile site.

2. **Crete a new `app.php` file with a name like, for example, `app_mobile.php` and change the following:**
    ```php
    $kernel = new AppKernel('prod', false);
    ```
    to:
    ```php
    $kernel = new AppKernel('mobile', false);
    ```
    Now your mobile site has its own environment and we can nicely create some custom configuration for it, disable
    mobile redirecting and activate desktop redirection instead.


3. **Create `config_mobile.yml` next to your `config.yml` and disable mobile redirecting. This should take care of the circular
    reference errors. Adding the `full` configuration activates desktop redirection.**

    Also you might want to define your routing file as mobile specific. If you do, just create new `routing_mobile.yml`
    file and use it just like the default `routing.yml`. This gives you nice opportunity to route requests to
    custom mobile specific controllers that can render views that are designed for mobile. This way you don't need to write
    platform specific conditions to your view files.

    ```yaml
    framework:
        router:
            resource: "%kernel.root_dir%/config/routing_mobile.yml"


    mobile_detect:
        redirect:
            mobile:
                is_enabled: false
            tablet: ~
            full:
                is_enabled: true
                host: http://site.com
        switch_device_view: ~
    ```

4. **Configure your http server: Make sure that in your http server virtual host, you make http://m.site.com use `app_mobile.php` as its script file
    instead of `app.php`.**

    After you have restarted your http server everything should work.
    Also remember to clear the cache if you do changes to configs or you might end to get frustrated for nothing.



TODO
---------

* Write more tests
* Add twig function `url_for_switch_view('mobile')` for generating switch view url's
