If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

A simple adapter, extending WordPress' \WP_Query class while implementing PHP's core Iterator interface.

Built mainly for, but not limited to usage with the twig templating language for PHP.

Getting started

Prerequisites

Installation

Installation instructions, with examples like the one below.

Usage

Require the vendor/autoload.php file either in your main plugin file, or functions.php, depending on what you are building.

The most effective way to use it

The simplest and most effective way to use this package is by using the PostCollection class. It's based around Php's IteratorAggregate interface and inspired by (e.g.) Laravel's Collection class and Symfony's Finder and LazyIterator classes.

It provides three static methods to create instances from various types of arguments.

Examples using PostCollection

The point of this class is you are able to loop through it, like you would with an array, only it is more memory friendly than an actual array.

The main implementation

Adapter

If you want to create an iterator for an existing WP_Query instance use the PostIteratorAdapter class. It uses the PostIteratorTrait.

Alternative

If you want to use another class that implements this functionality without sacrificing an existing inheritance chain, you can use the PostIteratorTrait instead.

It provides all the Iterator methods as shown below, it only requires you to implement two methods as shown below:

Development

Below is some info on development, (so feel free to fork this repo).

Code style & Formatting
