reCAPTCHA link in online web2py book

[lucas]

hello one and all,

the link for reCAPTCHA, or, "http://web2py.com/books/default/reference/29/recaptcha", under the online web2py book, "http://web2py.com/books/default/chapter/29/09/access-control#CAPTCHA-and-reCAPTCHA", seems to by unreferenced.

is this feature still working in the latest version of web2py, 2.27.1?  is it still free?  is it still good to use?

thank you, lucas

[lucas]

anyone on this, at all?

Sorry, I haven't used recaptcha, but I think there was a recent thread about it in the py4web forum.

Good luck

Hello.

Recpatcha is still working like a charm. 

Here are some examples about how to use it.

if you want to have Recaptcha in login form, set it like this:

in models.py

#import recaptcha

from gluon.tools import Recaptcha2

#enable recaptcha in login form.

auth.settings.captcha = Recaptcha2(request, public_key='key1', private_key='key2', label='')

If you want to use it in SQLFORM.

define some functions for convenience in models.py or in other place

ex: 

#function to be used in a form without database

def captcha_field(request=request):
    w = lambda x, y: Recaptcha2(request,
                                'public_key',
                               'private_key',
                               )

    return Field('captcha', 'string', label='', widget=w, default='ok')


#function to be used in a sqlform
def captcha_sqlform():
    recaptcha2 = Recaptcha2(request, 'public_key', 'private_key', '')

    return DIV(LABEL("", _class="form-control-label col-sm-3"),DIV(recaptcha2, _class="col-sm-9"), _class="form-group row",_name="recaptcha_form")

#append the recaptcha to sqlform

form = SQLFORM(db.table, keep_values=True)
form[0].insert(-1, captcha_sqlform())

This will add the recpatcha validation to the form.

Greetings.

Chris.
