Create Secure AJAX Forms with CAPTCHA, Realtime Validation & PHP Backend

Last updated on by Gabriel Livan

Back in the autumn of 2008, I have written a tutorial about how you can create a basic AJAX Contact Form that works with PHP Back-end. The post is one of the most popular here on BitRepository having over 8,000 monthly page views and over 440 comments so far.

Since many people asked me how they can do this and even hired me to offer them assistance with this application, I have decided to write a more advanced script with many features including CAPTCHA and Real-time Validation.

The script can be practically used to create any type of AJAXified, yet secure form that collects data and sends it to your email inbox including but not limited to:

  • Contact/Feedback Form
  • Support Form
  • Customer Survey Form
  • Online Product Order Form
  • Event Registration Form
  • Employment Form
  • Make a Room Reservation Online Form
  • Send Testimonial Form
  • Subscribe to Newsletter Form
  • Gift Order Form

Bumpbox – An Awesome Lightbox Clone with Support for PDF Files

Last updated on by Gabriel Livan

Bumpbox is a lightbox that besides the support for opening images, html files, FLV videos, and SWF files, can also be used to open PDF files. The integration of the script is quite simple: you add the scripts in the head section of the page, classes to the links that should use bumpbox and define a rel tag with the size that the lightbox should have. The nice thing about this lightbox is that it detects what kind of file you wish to show in the box, so you do not need to specify the type, easing the process of integration.
