How to achieve this in service portal widget

[VikramM1]

I need to create a catalog item with a variable which accepts date. When user requests an catalog item, it should check if the date entered in date variable is it from past. If yes, then it should display one alert message and clear the value from date field and abort the submission.

This is not about widget but just a  catalog item thing.

You need to create a variable on the catalog item(maintain items -> find your item -> New Variable)

then Add a UI policy that checks if the date ins i9n past and throw error -> EG here No Code date validations through (Catalog) UI Poli... - ServiceNow Community
