Hello, i have a couple of custom fields, that need validation:
1. How to restrict special characters in field (like è,é,ê,ě,ẽ,ē,ë,ů,ű,ũ,ǔ,ü,ú,ù,û)?
2. How to restrict parts or word in field? For example if any word in field contains "iene" or "yte" or "aite", etc. it should not allow
3. How to allow only 11 characters in field? And those 11 characters can be only numbers.

Hi,

You can do all that with the "Regular expression check" setting of your field if the "required" setting of the field is activated.
In it, you can provide a regular expression to restrict what can be provided by the user.
Here are the regular expressions ChatGPT proposes for each of your restrictions:
