Checking if a field is hidden and making it required if not.

Last updated: Jun 1, 2022
Is there any way of checking whether a field is 
hidden
for making it required if it isn't?

document
doesn't seem to contain any value regarding the 
hidden
status of a field.

Considering you know the logic about the hidden field, do you need to check if it’s hidden at all? Can’t you apply the same logic for your validation?

Would a required hidden field still be required?

Pretty sure it would.

Then I would need to know if it is hidden. Or I could conditionally make it required if the other field is empty.
For context, this is basically about conditional fields for a link type: internalLink & externalLink

I could make both required if both are empty. And make the hidden one not required if the other one has content.

Ah I see. Yes that makes sense.

But that might lead to a bit of confusion as both would be shown as required if none is provided. Although that might be compensated with a custom validation message.

Seems they are staying required even if hidden.

Having a boolean exposed on children of 
document
would be awesome.

I can actually see a 
hidden
field there but I think it refers to something else?

ref => {
      var parent = _ref.parent;
      return (parent === null || parent === void 0 ? void 0 : parent.linkType) !== "external";

That should simply be my current hidden condition function. Hm. Could I execute this check as well in the validation function and get a boolean back?

As I would be working with 
refs
, I would need to use the 
sanity.client
, but this seems to be only the function, so I would still need to get access to it as well.

I think I will give the "isItEmpty" check a shot first.
Jun 1, 2022, 8:31 AM
Actually you are right. I can also check using the same logic for validation. I make it required depending on the selected linkType.
Thank you for the help,

Yay! Glad you got it. 😊

The solution for future generations:

validation: (Rule) =>
        Rule.custom((currentValue, { parent }) => {
          return parent?.linkType === "internal" && !currentValue
            ? "A link value is required."
            : true
        }),
