HTML Forms generation and validation 2008.04.06 (Default branch)
04-07-2008
HTML Forms generation and validation is a PHP class that generates HTML forms supporting many built-in validation types on server and client sides. It prevents security attacks by discarding spoofed values, has multiple submit protection, outputs HTML for fields displayed as fully accessible or in read-only mode, and has field value filtering and reformatting. It can be extended with custom control plug-ins. AJAX based form submission, upload monitor progress bar, auto-complete text input, automatic layout renderer, calendar date, CAPTCHA, Google Maps world location selection, linked select, and animation effects plug-ins are available.
