AW: How does the captcha valid. in forms work?

[Christofer Dutz]

Hi Marco   As far as I understand it, the widget generates a string with the expected value and gives this an id. This is stored in the session. When rendering the widget to html an image with the name capcha-{id}.jpg is requested. Cocoon now takes this id to generate the image for that particular id containing the information in the session. All the Validator has to do now is to compare the value entered with the one stored in the session.   Hope I’m correct.   Chris   [ c h r i s t o f e r   d u t z ]   IT-Berater univativ GmbH & Co.

A description of the whole process would be great.... Thank you Marco
