Description
This sample project shows the most basic source code required to protect an PHP form with BotDetect CAPTCHA and validate the user input.
It can be used as a starting point when you are first learning how to use BotDetect.
Beta Release Warning
BotDetect PHP Captcha Library Beta is a work in progress, and we need you to guide our efforts towards a polished product. Please let us know if you encounter any bugs, implementation issues, or a usage scenario you would like to discuss.
Free Version Limitations
- The free version of BotDetect includes a randomized
BotDetectâ˘
trademark in the background of 50% of all Captcha images generated.
- It also has limited sound functionality, replacing the CAPTCHA sound with "SOUND DEMO" for randomly selected 50% of all CAPTCHA codes.
- Lastly, the bottom 10 px of the CAPTCHA image are reserved for a link to the BotDetect website.
These limitations are removed if you upgrade your BotDetect license.
