Piwik lets you assign Custom Variables to visit and/or pageviews (and site searches, events, etc.). Users can then create Custom Segments to get reports for all visits and pages matching a particular Custom Variable.
The goal of this ticket is to make creating segments with custom variables more user friendly.
Why are segments hard to use with Custom variables?
To create a segment with a custom variable, user has to know which slot the custom variable was created in (slot is a number from 1 to N). A segment to select only page views tagged with a particular author would like this:
This is hard to use by users who may not know which slot was a given custom variable set.
customVariableNamePage==name_herewhich would automatically select any page view with a custom variable name set with
name_here. The generated SQL would look something like
custom_var_k1 == name_here OR custom_var_k2 == name_here OR custom_var_k3 == name_here OR custom_var_k4 == name_here OR custom_var_k5 == name_here
customVariableNamewould show all possible custom variable names for all slots.
Adding this new "magic segment" matching any slot should make the act of creating custom segments with custom variables much easier. Thoughts?
Added comment in https://github.com/piwik/piwik/pull/8754#issuecomment-139464546 also seeing it a bit dangerously as results can get inaccurate when using it right? Eg when a search term matches different custom variables. Eg
contains 2. may apply to a custom variable
Android version number but also
App version number
