Yii 2 FAQ

As part of our ongoing series to build a reusable template in Yii 2, we are going to do a tutorial on our FAQ model. We will focus mostly on our frontend implementation, but we will also be talking about the data structure, differences in the frontend and backend, and we will make use of Yii 2’s ArrayDataProvider, a very handy iterator for use in sending data to the views.

Ok, so if you are just joining the blog, and have not yet gotten started on the basics, I recommend my book, Yii 2 For Beginners, which is a step by step guide to get you installed, up and running, and into development. The book is oriented toward beginning programmers who are just making the transition into frameowrk development and in addition to explaining how things work, we take care to explain why things are done they way they are done.

This blog is meant to be an extension of the book, great for tips and tutorials, which will be included in the quarterly updates of the book. Anyone who purchases the book is entitled to the free quarterly updates for the entire life of the book, so hopefully you can take advantage of that.

One of the other big themes I like to explore is the idea of working for a client and keeping the client satisfied. I’m just going to assume that you will be building applications for a client who is difficult to please.

When we think of FAQs, we think of simplicity, just questions and answers, and simplicity typically serves us well. But if we think about our demanding client and things that are important to them, the order of the questions, for example, might be very important. And obviously, the order they want will most likely not match the ascending or descending timestamp for creation or alphabetical order.

In most cases, the client won’t even know what order they want the questions in until long after the project has been developed. So what we need is a way for them to determine the order via backend UI. Now this is really simple to do of course. We just add a faq_value field, with a data type of int, that we can sort either ascending or desceding depending on our preference.

For example, in an ascending sort, an FAQ with a value of 10 will be higher on the list than an FAQ with a value of 20. And as long as we give the client a method for changing the value of an FAQ from backend UI, the problem is anticipated and solved before it ever becomes an issue.
