The Piwik application (vsn 2.16.1-b2) is inserting the custom dimension data into the wrong columns. To reproduce
Configure a Web site with 15 visit dimension and 15 action dimensions. Create a Web site with 7 visit dimensions and 7 action dimensions . Run the following test program

The tracking url sent is:


The tracking url correctly matches the dimension and values.
On querying the database the log_link_visit_action_table has the misplaced values

Custom idcustomdimension Column Value
Column Name
1 1 dim%201%20Tue,%2015%20Mar%202016%2021:49:54%20GMT
2 3 dim%203%20Tue,%2015%20Mar%202016%2021:49:54%20GMT
3 5 dim%205%20Tue,%2015%20Mar%202016%2021:49:54%20GMT
4 7 dim%207%20Tue,%2015%20Mar%202016%2021:49:54%20GMT
5 9 null
6 11 null
7 13 null

The idcustomdimension value was obtained by querying the custom_dimensions table and matching the scope and index for this web site.
It appears that the problem is the dimension index value is not being used to place the data into the correct column, its more likely that the custom dimension idcustimdimension value is being used. This occurs for both visit and action scoped custom dimension data.

@tsteur commented on March 16th 2016 Owner

There is in general the idcustomdimension and there is an index for each custom dimension. The idcustomdimension is what you see in the API, eg dimension2. The index defines in which column it should actually go. For example dimension2 might be stored in custom_dimension_1 column.

Configure a Web site with 15 visit dimension and 15 action dimensions. Create a Web site with 7 visit dimensions and 7 action dimensions . Run the following test program

To reproduce this we'd need to know whether we're supposed to create first all visit dimensions or first all action dimensions or whether you created them in a specific order? Otherwise the mapping of idcustomdimension to an index will be different in our test.

This will ensure that the idcustomdimension value doesn't always match the dimension index. Then you can see if the custom dimension values a placed in the correct columns.

Didn't mean to close the issue. How does idcustomdimension map to the database columns? Surely for each dimension the index column value should determine how the value maps to each column custom_dimension_1, custom_dimension_2, .... ?

Not exactly. The id in custom_dimension_1 maps to idcustomdimension for the given idSite. The index column in custom_dimenions table actually references to the correct column in log_visit / log_link_visit_action.

Thanks for the clarification, please can you confirm the that you can reproduce the problem I'm seeing.

@tsteur commented on March 31st 2016 Owner

I will try to reproduce it now but looking at the screenshots you posted everything looks good

@tsteur commented on March 31st 2016 Owner

Works as expected for me.

Just to mention it again custom_dimension_7 doesn't mean it will be stored in db column custom_dimension_7 as it can reference to either log_visit table or log_link_visit_action table.

@3dmashup commented on March 31st 2016

Ok, thanks for the investigation. What decides where the value for custom_dimension_7 for an action scoped custom dimension is stored?

@tsteur commented on March 31st 2016 Owner

index column in custom dimensions table
