Theme Functionality

While the main code base is object-oriented, we still need simple functions for trivial things. This functionality is placed inside inc folder. There are 3 files inside be default:

• helpers.php
• hooks.php
• template-funcs.php

Helpers

Helpers are simple functions, which perform some simple data processing. They can be some data formatters, format adapters, or similar.

Example: we have a product catalogue on our site (no e-commerce), and we need to have a lot of product banners over the site. Each banner prints price along with all other information and you want to be sure it has the same format like "{currency} {amount with 2 digits}". You can create a simple helper function {prefix}_price(), and use it inside the templates

Hooks

Most hooks are registered inside the app. However, there are some hooks, which are not important or have a very generic definition. We place such hooks inside this file.

Example: Body class adjustment based on some logic.

Example: Excerpt length hook.

Template functions

The main part of Wordpress templates is The Loop. Functions, that generate some content for post/pages or custom post types, are added here.

Example: {prefix}_posted_on() printed formatted post date

Available functions by default:

Function	Description
{prefix}_posted_on()	Print formatted post date and post author
{prefix}_entry_footer()	Print formatted post categories, tags and other meta info
