In the settings page enter your Piwik website ID.
|

26
|

You will also need to define what user roles should be tracked.

Custom variables

|
|

One example for custom variables tracking is the "User roles" tracking. Enter
|
|
38
|
the below configuration data into the custom variables settings form under
|
|
39
|
admin/config/system/piwik.
|
|
40
|
|
|
41
|
Slot: 1
|
|
42
|
Name: User roles
|
|
43

Advanced Settings
|
|
56
|
=================
|
|
57
|
You can include additional JavaScript snippets in the advanced
|
|
58
|
textarea. These can be found on various blog posts, or on the
|
|
59
|
official Piwik pages. Support is not provided for any customisations
|
|
60
|
you include.
|
|
61
|
|
|
62
|
To speed up page loading you may also cache the piwik.js
|
|
63
|
file locally. You need to make sure the site file system is in public
|
|
64
|
download mode.

Known issues
|
|
68
|
============
|
|
69
|
Drupal requirements (http://drupal.org/requirements) tell you to configure
|
|
70
|
PHP with "session.save_handler = user", but your Piwik installation may
|
|
71
|
not work with this configuration and gives you a server error 500.
|
|
72
|
|
|
73
|
1. You are able to workaround with the PHP default in your php.ini:
|
|
74
|
|
|
75
|
[Session]
|
|
76
|
session.save_handler = files
|
|
77
|
|
|
78
|
2. With Apache you may overwrite the PHP setting for the Piwik directory only.
|
|
79
|
If Piwik is installed in /piwik you are able to create a .htaccess file in
|
|
80
|
this directory with the below code:
|
|
81
|
|
|
82
|
# PHP 4, Apache 1.
|
|
83
|
<IfModule mod_php4.c>
|
|
84
|
php_value session.save_handler files
|
|
85
|
</IfModule>
|
|
86
|
|
|
87
|
# PHP 4, Apache 2.
|
|
88
|
<IfModule sapi_apache2.c>
|
|
89
|
php_value session.save_handler files
|
|
90
|
</IfModule>
|
|
91
|
|
|
92
|
# PHP 5, Apache 1 and 2.
|
|
93
|
<IfModule mod_php5.c>
|
|
94
|
php_value session.save_handler files
|
|
95
|
</IfModule>
|
