Multiple Dropdown Lists Using jQuery, Ajax, MySQL and PHP - Udemy

This is a short course designed to get you started using the jQuery AJAX method to post data to a PHP script and work with the retrieved database records. It is a follow along style course, not one to teach you every aspect of PHP, jQuery or MySQL...there are other courses for that. This course is quite specific in its focus.

In the course you will learn how to create the database tables and populate with CSV files before learning how to use the jQuery AJAX method to post data to a PHP script to retrieve database records and populate a dropdown list. This is commonly seen when completing HTML forms and you have to select the country and the state will auto-populate from the selection.
