PHP Captcha & AJAX Contact Form is a business-oriented contact form template designed to be integrated into existing HTML or PHP websites.

The form uses AJAX submission to avoid full page reloads and includes CAPTCHA protection to help reduce common spam-bot and unwanted email submissions.

It provides multiple validation options, automatic focus on incorrectly completed fields, SMTP support, and the ability to attach files to emails. The system also includes functionality for handling uploaded attachments before and after sending mail.

No database is required, making the form suitable for websites that need a lightweight contact solution without adding database dependencies.

The package includes AJAX submission, CAPTCHA anti-spam protection, client-side validation, SMTP support, attachment handling, commented code and documentation.
