A Server-Side Calculated Field For Laravel Nova
===============================================

[](#a-server-side-calculated-field-for-laravel-nova)

**Note from Qskousen:**

I've just updated this package to work for Nova 4, all the credit still belongs to codebykyle for their original work here:

**Changes:**

Removed dependency on outdated `numeral` package. Instead, it will format using [Intl.NumberFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat).

In light of that, the `->numberFormat()` function signature has changed to `->numberFormat($format, $locale = 'en-US')`, where `$format` is a valid format JSON string from `Intl.NumberFormat` (link above), for example, `->numberFormat("{style: 'currency', currency: 'usd'}")`. In this instance, the locale is left to default of `en-US`.

The formatting only works in some specific scenarios. Doesn't work very well except on a readonly listener field. I don't think this was fully implemented in codebykyle's version, which is probably why it wasn't in the readme. Results may vary.

**Original readme follows**

This package contains two Nova fields required to do server-side calculations from the Nova client. The user can optionally override the calculated value on the form.
