Combining Map & Get (or First) functions to get Values from Arrays

The built-in functions map, get, first (or `last) allows you to access values within an array containing collections.

First, use the map function on an array, which returns another array of filtered values —
map(array; key; [key for filtering]; [csv-values for filtering])

Then, the built-in function get (or first/last) to get a specific, single item from the resulting array —
get(array; path)

You will get something that looks like these —

{{ get(map(array; "value"; "name"; "content-type"); 1) }}
{{ first(map(array; "value"; "name"; "content-type")) }}

Map Function Parameters: Step-by-Step

To easily remember how to use each of the parameters of the map function, think of it this way:

  1. From this array (of collections),
  2. I want to get all the the values for the property/key named _______,
  3. Where another property/key _______
  4. has the exact case-sensitive value _______

Example

1. From this array (of collections) user_column_data

2. I want to get all the the values for the property/key named string_value

3. Where another property/key column_id

4. has the exact case-sensitive value EMAIL

5. Output

make-map-get5
make-map-get5738×402 81.3 KB

e.g.:

{{ first(map(5.user_column_data; "string_value"; "column_id"; "EMAIL")) }}

Using Join Function to Transform an Array into a Single Text Variable

You can also combine map with join to join the values into a single text string —
{{ join(map( ... ); delimiter) }}

e.g.:

{{ join(map(array); ", ") }}

For more information, the documentation for the above functions can be found in the Help Centre and the “Mapping with Arrays” link below. You should also complete the tutorials in the Make Academy, especially Using get() and map() functions as this is the most important knowledge you need to understand so that you can successfully apply it when building scenarios using Make.
