The TutsPlus.com site has posted the next in their "Building Your Startup" series of tutorials covering the use of Yii2 to create a calendaring application. In this new part of the series they continue migrating some functionality over to use an Ajax-powered system, reducing the need for page reloads.

Last week, I delved deeper into Ajax to transform the meeting scheduling experience into a fully ajaxified model and eliminated the need for page refreshes. I got about halfway, focusing mostly on the straightforward elements.

In today's tutorial, I'll guide you through the more complex content panels that required a lot more troubleshooting, research, debugging, brainstorming, and recoding. [...] I'm also going to show you how I used Google's Chrome browser developer console to help me identify the broken areas—which can be especially difficult when working with Ajax between PHP and JavaScript. It's like light at the end of the tunnel of darkness.

The tutorial then walks through the updates needed to move over various pieces of functionality to the Ajax-driven model:

• adding meeting participants
• adding dates and times
• adding meeting places

There's also a few screenshots included of the Chrome developer console and what some of the example request/responses look like, helping you debug your own development work.
