Lesson 21 - E-shop in PHP - ProductHelper and JavaScript

In the previous lesson, E-shop in PHP - Product detail logic, we prepared the models and the controller for product details as well as user reviews. In today's tutorial, we'll prepare everything needed to add the product template to our project :)


Since we want to work with products in a serious manner, we'll need a ProductHelper class. Its main purpose will be price formatting and displaying star ratings. We'll need to use these things from several places in the application. Otherwise, we'd have to copy loops and conditions into the template, which would make things really confusing.


class ProductHelper



This method will generate empty and full stars as Bootstrap glyph icons, based on the sum of the product ratings and their count. If the number of ratings isn't included, it'll simply treat the sum as the number of stars that it needs to render.
