You can build forms consisting of different fields in the Form Builder.
Existing Form fields¶
The Captcha Form field is based on Gregwar/CaptchaBundle.
You can customize the field by adding configuration to
1 2 3 4 5
The example configuration above resizes the Captcha image (line 3), changes the error message (line 4), and enables the user to reload the code (line 5).
For information about available options, see Gregwar/CaptchaBundle's documentation.
If your installation uses Varnish to manage content cache, you must modify the configuration to avoid issues with the Captcha field. For more information, see Ensure proper captcha behavior.
