As it is known, the contact form in Joomla! can be used easily for automatic delivery of a spam (that is, instead of a e-mails database, it is quite enough to have a database of the sites created using Joomla!). To be protected from this, we’ll add CAPTCHA on contact form. As well as in previous article (CAPTCHA by own strength: Backend login form), we’ll use “kcaptcha” script, though it is possible to embed any other captcha-script in the same way.
Allow me to begin a series of articles devoted to embedding of CAPTCHA in Joomla. I know only one project, allowing such embedding, it is Security Images. But this component has some disadvantage, e.g. its size is 1.5Mb in zip-archive. I’ll tell how to embed such a protection by own strength.
For the present I plan following articles:
- CAPTCHA by own strength: Backend login form
- CAPTCHA by own strength: Contact form
- CAPTCHA by own strength: Registration form and Lost password form
- CAPTCHA by own strength: Frontend login form
