How to create a key-value object/collection, and add to an associative array containing key-value pairs

How To

Hi,
With Make I can create an associative array based on a collection.
Also I can add to a “normal” array via the “add()” function.
But could not find in the documentation how to add a “key => value” entry to an associative array.

Is it possible, can you help me with that? Thank you.

Welcome to the Make community!

Could you provide examples of what you want to achieve?

When you say “normal”, did you mean an array containing primitive values? (i.e.: none of the items are collections or arrays)

If I understand your question, you have an array of collections:

You want to add a new collection in the same format to the array using the add function, is this correct?

{ 
  "key": "key4",
  "value": "value4"
}

I use the Parse JSON module in the JSON app to create a more complex data structure. This gives you complete control of the array, key/value structure. Then when it executes it will parse the JSON and create an array with the key value pairs you want. If you create multiple structues under the top array then those wil be generated as output bundles.

You can aggregate these outputs into one array using an array aggregator and get the structure you want then.

One way of doing that is use the Parse JSON module to create the new object (collection)

Then you can add the new collection to the array

No problem, glad I could help!

Quick tip: Did you know, you can convert a collection to key-value pairs using the built-in function toArray? The inverse of that is toCollection! These two advanced functions are not commonly known and you might find yourself using them especially if you are adding/modifying KVPs.
