My idea is: Let’s finally allow Mautic users to use calculated values in campaign steps. E.g. - “Update contact field with current time & date” or maybe even - “Update contact field with value from elsewhere (e.g. from a different field)” - and maybe beyond contact data Not sure if we should start with the most important flavours, “hard-coded” - or if we should come up with a sophisticated general framework. Maybe we can fid something in between. 🙂 I think these groups of people would benefit from this idea: Why I think they would benefit from this idea: Any code or resources to support this idea: Are you willing to work on this idea?: Yep What skills and resources do you need to explore this further? ---

This would be a great feature. Some of the use cases of calculated fields I can think about are as follows: 1. A formula field that could do a timestamp on a field when another field changes 2. A formula field that could follow a logic of if, then… 3. A formula that could do math operation (+,-,\*,/) as well as functions like SUM, AVG, MEAN, MEDIAN ---

I am in need of (+,-,\*,/) fields. Anyone have a solution for this? ---

This would be a very nice feature. ---

@ekke we discussed this in the release planning meeting - some of these features are implemented for forms: > > > | Q | A > | --------------------------------…------ | --- > | Bug fix?

Adding this (twig-like) suffix was done to prevent accidentally parsing meaningful strings as date.

Open this PR on Gitpod or pull down for testing locally (see docs on testing PRs \[here\](https://contribute.mautic.org/contributing-to-mautic/tester)) > 2. Create or edit a form > 3. Add date, datetime or hidden input fields > 4. Set the default value to any datetime parsable string. Append \`|date\` for hidden fields. > 5. Open the form and inspect the html code > 6. See that the default values are replaced by actual date time values So we could perhaps repurpose some of this. Is it still a feature you’re looking for Mautic to implement? ---

Absolutely, we’d still love to see it, but not invest time atm (other priorities like email builder and form types) @silavapi ---

OK thanks for responding, just wanted to check in as it was a long time back!
