Wegmeister:
  Recaptcha:
    requestMethod: 'Wegmeister\Recaptcha\RequestMethod\CurlPostWithProxy'
    httpProxy: 'http://yourproxy.com:1234'

Usage with Neos.Form

type: 'Neos.Form:Form'
identifier: someIdentifier
label: Label

  -
    type: 'Neos.Form:Page'
    identifier: page-one

Usage with Neos.Form.Builder

Add a Captcha form element to your form

Configure reCaptcha site key, secret key and other settings from the Inspector

❗ The old ReCaptcha form element with an additional validator required will be removed in Version 3.x of this plugin. Please update to the new form element.

Global settings for Neos.Form and Neos.Form.Builder

This plugin will automatically load the required recaptcha/api.js file once. If you already load this file yourself, you can disable it in the settings. Furthermore, there is a polyfill for Element.prototype.closest. If you don't need it, you can disable this, too.

Neos:
  Form:
    presets:
      default:
        formElementTypes:
          'Wegmeister.Recaptcha:Captcha':
            renderingOptions:
              # If you have already included the ReCaptcha api.js file yourself, set this to false.
              includeAPIScript: true
              # If you don't need a closest polyfill in js, set this to false.
              includeClosestPolyfill: true
            # Set your siteKey and secretKey in your settings file globally (or if you want to keep it outside your git)
            properties:
              siteKey: 'your-public-key'
              secretKey: 'your-private-key'

Usage with Neos.Fusion.Form

❗ Currently, only reCaptcha v3 is supported with Fusion Forms. Feel free to provide a PR with support for v2.

Add a FieldContainer with the CaptchaV3 element to your form:

<Neos.Fusion.Form:FieldContainer field.name="captchaV3">
    <Wegmeister.Recaptcha:FusionForm.CaptchaV3 siteKey="your-site-key" action="your-action-name" includeApiScript={true} />
</Neos.Fusion.Form:FieldContainer>

Set the field name based on our needs, but make sure to use the same field name in the schema (see below).

Since an error message is rendered at the position of the form element, you should place it either at the beginning or at the end of the form.

The following options are available:

• siteKey (required): The reCaptcha v3 website key.
• action: For statistical purposes, use the action to group the captcha evaluations according to your usage, e.g. "contactForm". More information
• includeApiScript: Whether or not the reCaptcha API script should be included. If you already include it globally, set this to false.

Then, add the field to the schema and configure the Validator:

captchaV3 = ${Form.Schema.string().validator('Wegmeister.Recaptcha:IsValid', {secretKey: 'your-secret-key', errorMessage: 'The reCaptcha check failed. Try submitting the form again.'})}

Make sure that the key (e.g. captchaV3) matches the key in the FieldContainer (see above).

The following options are available:

• secretKey (required): The reCaptcha v3 secret key.
• errorMessage: Use this to override the error message in case of a failed captcha check.

i18n

Currently, the following languages are supported: English, German, French and Dutch Feel free to send us labels in other languages so we can add them to the plugin.
