Advanced Custom Fields: Validated Field

Description

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.

Features

1. Input Masking – easily set masks on text inputs to ensure data is properly formatted.
2. Server-Side Validation – validate the inputs using server side PHP code or regular expressions.
3. Uniqueness – ensure that the value being updated is not already in use.
4. Repeater Fields – validated fields within a Repeater Field.
5. Read Only – specify a field as read-only allowing it to be displayed but not updated.
6. WordPress Multi Language – compatible with multilingual sites using the WPML plugin.
7. Conditional Logic – show and hide validated fields based on the values of other “switch” fields.

Compatibility

Requires Advanced Custom Fields version 4.0 or greater.

Installation

FAQ

I’ve activated the Validated Field plugin, but nothing happens

Ensure that you have Advanced Custom Fields installed and that it is activated.
Validated Field will appear as a new input type in the field group editor.

Configuration Options

Global configurations for the Validated Field plugin can be found in the WordPress Admin under Custom Fields > Validated Field Settings.

Do NOT USE!! It will crash your site. Hasn’t been updated in six years! PHP Warning: Declaration of acf_field_validated_field::validate_field($valid, $value, $field, $input) should be compatible with acf_field::validate_field($field) in /[redacted]/wp-content/plugins/validated-field-for-acf/validated_field_v5.php on line 368
