= sfGoogleAnalyticsPlugin plugin =

Easily add [http://www.google.com/analytics Google Analytics] tracking code to your presentation layer.

''This documentation is a work in progress. Thank you for your patience.''

== Installation ==

=== 1. Install ===

You can install using the `plugin-install` task:

{{{
php symfony plugin-install sfGoogleAnalyticsPlugin
}}}

You can also pull the code directly from the [http://svn.symfony-project.org/plugins/sfGoogleAnalyticsPlugin/trunk Subversion repository] using a `svn checkout` or the `svn:externals` property on your project's `/plugins` directory.

Once the plugin code is accessible to your project, you need to add the `sfGoogleAnalyticsFilter` to your filter chain:

{{{
#!yaml
rendering: ~
security:  ~

# insert your own filters here
sf_google_analytics_plugin:
  class: sfGoogleAnalyticsFilter

cache:     ~
common:    ~
execution: ~
}}}

''NOTE: This is the symfony 1.1 `filters.yml` file. The equivalent symfony 1.0 file looks slightly different.''

=== 2. Configure ===

Basic configuration is done in your application's `app.yml` file:

{{{
#!yaml
all:
  sf_google_analytics_plugin:
    enabled:      on
    profile_id:   XX-XXXXX-X
    tracker:      google
}}}

You'll have to copy the `profile_id` value out of the tracking code Google supplies for your site profile. This value typically starts with the letter U and ends with a single digit.

This plugin defaults to using the older `urchin` tracker. To take advantage of the latest featureset of Google Analytics, change the `tracker` value to `google` for the older snippet or `asynchronous` for the more performant one. This will insert the new `ga.js` tracking code into your project.

== Advanced Usage ==

This plugin provides much more functionality than a simple insert of your tracking code. Here are some highlights:

=== How do I customize the name a page is tracked as? ===

If you would like to track a certain page as something other than what appears in the browser address bar, you can do so by modifying the `page_name` parameter in `module.yml`:

{{{
#!yaml
all:
  myAction:
    sf_google_analytics_plugin:
      params:
        page_name: something_else
}}}

For finer control over when the alternate page name is used, you can access the tracker object directly in your action. This also exposes additional funcionality. 

==== Option: `use_flash` ====

For example, if you want to track a successful form submission for a form that redirects to the same page on success and on error:

{{{
#!php
<?php

class mainActions extends sfActions
{
  public function executeContact()
  {
    // form submission logic...

    if ($success)
    {
      $this->getTracker()->setPageName('/contact/success', array(
        'use_flash' => true,
      ));

      $this->setFlash('feedback', 'Thank you!');

      $this->redirect('main/contact');
    }
  }
}
}}}

In this example, the request after the successful form post will be tracked as `/contact/success`.

==== Option: `is_route` ====

One more option available is the `is_route` option. When this flag is applied, the string provided for a page name will be passed through `sfRouting` before being added to the page. Using this option allows you to centralize all URLs, those real and for tracking purposes only, in your application's `routing.yml` file:

{{{
#!yaml
contact:
  url:    /contact
  param:  { module: main, action: contact }

# be sure the tracking rule comes AFTER the real rule so the application 
# doesn't use it for any url_for('main/contact') calls
track_contact:
  url:    /contact/success
  param:  { module: main, action: contact }
}}}

{{{
#!php
<?php

class mainActions extends sfActions
{
  public function executeContact()
  {
    // form submission logic...

    if ($success)
    {
      $this->getTracker()->setPageName('@track_contact', array(
        'use_flash' => true,
        'is_route'  => true,
      ));

      $this->setFlash('feedback', 'Thank you!');

      $this->redirect('@contact');
    }
  }
}
}}}

=== How do I selectively disable tracking? ===

You can easily configure the tracking code for a single module or even a single action by using the `module.yml` configuration file:

{{{
#!yaml
all:
  # disable tracking for this module...
  sf_google_analytics_plugin:
    params:
      enabled off
  
  # ...or for a single action
  index:
    sf_google_analytics_plugin:
      params:
        enabled off
}}}

Alternatively, you can access the tracker object directly from inside your action:

{{{
#!php
<?php

class mainActions extends sfActions
{
  public function executeIndex()
  {
    $this->getTracker()->setEnabled(false);
  }
}
}}}

=== Can I insert the tracking code at the top of my page? ===

You can configure this in `app.yml`:

{{{
#!yaml
all:
  sf_google_analytics_plugin:
    profile_id:   XX-XXXXX-X
    insertion:    top
}}}

=== Can I track demographic information? ===

You can expose whatever information you store on your users (that your privacy policy allows, of course) to Google Analytics. This is best done in your sign-in routine. For example, if you're using [wiki:sfGuardPlugin]:

{{{
#!php
<?php

class myUser extends sfGuardSecurityUser
{
  /**
   * Overload to add custom tracking variables to the current user.
   * 
   * Variables are added using flash, assuming sign in will be followed by a 
   * redirect.
   * 
   * @see sfGuardSecurityUser
   */
  public function signIn($user, $remember = false, $con = null)
  {
    parent::signIn($user, $remember, $con);

    // assign tracking variables
    if ($gender = $user->getProfile()->getGender())
    {
      $this->getTracker()->setVar('gender/'.$gender, array(
        'use_flash' => true,
      ));
    }
    if ($this->hasCredential('moderator'))
    {
      $this->getTracker()->setVar('userType/moderator', array(
        'use_flash' => true,
      ));
    }
  }
}
}}}
