Search form development with Ajax, PHP and MySQL

The client provided an already operating website, as well as the structure of an existing table in the MySQL DBMS. The task required building a form for searching across the fields of this table in the MySQL DBMS, and it was also necessary to ensure that data was sent and received via Ajax technology. A mandatory condition was also to validate the form data before submission for completeness, and to add a security image - a captcha.
