10 | Using quintagroup.z3cform.captcha in a z3c.form form is simple. |
---|
11 | Just add a Captcha field to your schema, use CaptchaWidgetFactory |
---|
12 | widget factory for this field and away you go: |
---|
13 | |
---|
14 | >>> from zope.interface import Interface |
---|
15 | >>> from z3c.form import form, field |
---|
16 | >>> from quintagroup.z3cform.captcha import Captcha |
---|
17 | >>> from quintagroup.z3cform.captcha import CaptchaWidgetFactory |
---|
18 | |
---|
19 | Now define form schema with Captch field |
---|
20 | |
---|
21 | >>> class ICaptchaSchema(Interface): |
---|
22 | ... captcha = Captcha( |
---|
23 | ... title=_(u'Type the code'), |
---|
24 | ... description=_(u'Type the code from the picture shown below.')) |
---|
25 | |
---|
26 | And set proper widget factory for the captcha field |
---|
27 | |
---|
28 | >>> class CaptchaForm(form.Form): |
---|
29 | ... fields = field.Fields(ICaptchaSchema) |
---|
30 | ... fields['captcha'].widgetFactory = CaptchaWidgetFactory |
---|
31 | |
---|
32 | |
---|
33 | and z3c.form will take care of the rest. The widget associated with this field |
---|
34 | will render the captcha and verify the use input automatically. |
