= Validated Field Add-On =
The **Validated Field** add-on for [Advanced Custom Fields](
provides a wrapper for other input types which allows you to provide client side input masking using the jQuery
[Masked Input Plugin](, server side validation using either PHP regular expressions
or PHP code, the option of ensuring a field’s uniqueness for all posts by `post_type` and `meta_key`, `post_type`, or site wide, or a
single post by meta_key, as well as marking a field as read-only. Edit your fields in the ACF Field Group editor and update code using the ACE.js
IDE with autocomplete and syntax validation.
