CAPTCHA is a simple test to determine if a user is a computer or
a human. It is used to prevent spam abuse on the websites. So if
you use CAPTCHA in your application, this can help in stopping some
bots and making life harder for other bots in accessing or using
your project. You can add CAPTCHA to the
Add/Edit/Login/Register/Password reminder pages.
To add CAPTCHA to a web page, follow the instructions below.
| 1.
|
Proceed to the Visual
Editor and select a page you wish to modify. |
| 2.
|
Right-click somewhere on the page, select Insert -> CAPTCHA. |
| 3.
|
On the event dialog opened click OK. |
| 4.
|
New page element labeled <Table name>_captcha will appear
on the page. You can drag this element to change its location. |
Example
 Note: when a
user types the CAPTCHA code correctly, the CAPTCHA will not be
shown next four times during one session.
