I searched the web for the solution to send multiple custom dimensions to google analytics.
the old tag ga was easy to configure like so :
ga('create', 'UA-ID', 'auto');
ga('set', 'dimension1', value1);
ga('set', 'dimension2', value2);
ga('set', 'dimension3', value3);
ga('send', 'pageview');
this would send all of the 3 custom dimensions.
the problem occurs with the new gtag.js I tried lots of ways to configure multiple custom dimensions. the documentation shows how to configure 1 custom dimension as so :
gtag('config', 'UA-ID', {
'custom_map': {'dimension1': 'value'}
});
gtag('event','eventname', {'valuename':value});
This works [for 1 dimension] but I can't figure out how to send multiple custom dimensions.
[tried sending the object with 2 fields of dimension , tried to duplicate the config custom map with different dimensions - it didn't work]
Any ideas ?
Custom dimensions and metrics are very similar, but there is one difference: A custom dimension either has an event scope or a user scope, and a custom metric always has an event scope.
There are four levels of scope: product, hit, session, and user: Product – value is applied to the product for which it has been set (Enhanced Ecommerce only).
You can still use the Legacy version of the code but you have to send it inside a JSON instead, as the example
--Option I--
-- Set Option --
gtag( 'set' , {'dimension1' : "yxz"} ); // Set a Single Element
gtag( 'set' , {'dimension2' : "abc",'dimension3' : "123"} ); // Set multiple Elements
gtag('config', 'UA-1-1'); // Pageview with 3 cd
--Option II--
-- Map Function--
gtag('config', 'UA-ID', {
'custom_map': {'dimension1': 'value',
'dimension2': 'value2',
'dimension3': 'value3'}
});
gtag('event','eventname', {'value1':"1",'value2':"2",'value3':"3"});
