ACF checkbox field not getting updated in wordPress rest API

[raguvaranrceo]

My user edit rest api call working fine with ACF version 6.1.4. From 6.1.5 the check box field not getting update.

Response: { "code": "rest_invalid_param", "message": "Invalid parameter(s): acf", "data": { "status": 400, "params": { "acf": "acf[test][0] is not one of 0, 0, and 0." }, "details": { "acf": { "code": "rest_not_in_enum", "message": "acf[test][0] is not one of 0, 0, and 0.", "data": null } } } }

Hey @raguvaranrceo,

Could you please send us a screenshot of your checkbox field configuration in the field group? We made some changes in ACF 6.1.5 to support folks who use values like:

0: Zero
1: One
2: Two

But it seems like it must be causing some issues with your configuration.

Hey @raguvaranrceo,

Thanks so much for your bug report here. We've confirmed this is an issue when the checkbox doesn't contain any keys in the field values.

Attached is a patched version of the file: includes/fields/class-acf-field-checkbox.php, if you unzip this and drop it into your ACF install that should get you back up and running until we release the fix for this in our next release.

Alternatively, you can manually update the get_rest_schema function in this file to:

        /**
         * Return the schema array for the REST API.
         *
         * @param array $field
         * @return array
         */
        public function get_rest_schema( array $field ) {
            $schema = array(
                'type'     => array( 'integer', 'string', 'array', 'null' ),
                'required' => isset( $field['required'] ) && $field['required'],
                'items'    => array(
                    'type' => array( 'string', 'integer' ),
                ),
            );

            if ( isset( $field['default_value'] ) && '' !== $field['default_value'] ) {
                $schema['default'] = $field['default_value'];
            }

            // If we allow custom values, nothing else to do here.
            if ( ! empty( $field['allow_custom'] ) ) {
                return $schema;
            }

            /**
             * If a user has defined keys for the checkboxes,
             * we should use the keys for the available options to POST to,
             * since they are what is displayed in GET requests.
             */
            $checkbox_keys = array_map(
                'strval',
                array_diff(
                    array_keys( $field['choices'] ),
                    array_values( $field['choices'] )
                )
            );

            // Support users passing integers for the keys as well.
            if ( empty( $checkbox_keys ) ) {
                $schema['items']['enum'] = $field['choices'];
            } else {
                $checkbox_keys           = array_merge( $checkbox_keys, array_map( 'intval', array_keys( $field['choices'] ) ) );
                $schema['items']['enum'] = $checkbox_keys;
            }

            return $schema;
        }

    }
