Input field required based on select

[ken]

Site: classic asp
Database: MSSQL

I have a form with a select and a hidden input as follows:

If select = x, the input is displayed and I want the input field required
if select <> x, the input will remain hidden and it can’t be required

Show and hide is working fine, just need help with validation only when the field is visible. Thanks!

@ben's solution might help you out.

Making a form field visible when a dropdown select is of a certain value

I put a select field in a form with text values as choices in the table with one of the choices being “Other”. I have another field which I’d like to have appear when a user selects “Other” in the select field. I tried a dynamic attribute of show to the value of the select field. That doesn’t seem to work for me. Is that the right way to do this? Thanks, Rick

Thanks Scott, I have the show and hide function working fine, just need help with the validation

@ken,

When you say validation, are you talking about the app connect side or the server action side?

[ken]

Just want it required on the app connect side, if select = x, then I want them to be required to fill out the input. Does that make sense?

Ken, have you tried making the form elements disabled (in addition to hiding them) ?
I’m struggling myself with my first form validation implementation.
This seems to do the trick for me and client side validation seems to work fine.

(But I still get “required” errors on the server side.
EDIT : fixed, the “import” form feature put variables in POST but my form was configured with GET variables.)

Great Idea, i will try that. Thanks
