DustPress supports Composer’s autoload feature. If you have it enabled, you don’t have to do anything else to use DustPress. If not, you need to require dustpress.php in your functions.php.

Usage

You need to call dustpress(); in your functions.php to enable DustPress. It must be naturally be done after requiring the library itself if you haven’t used Composer’s autoload feature.

Within your theme there must be two directories called models and partials to use DustPress. Their purpose will be explained later in this file.

The basics of using DustPress are very simple. Unlike traditional WordPress theme development, DustPress relies on MVVM, or Model View ViewModel architecture in which fetching data and displaying it to the user are separated into different modules.

Data models

Even though implementing an almost completely new development pattern to WordPress theme developers, DustPress still uses some of the WordPress core functions. The naming of the data models and view partials follow the naming conventions of traditional WordPress themes. The model for a single post should be named single.php etc.

In WordPress, your custom page templates could be named pretty much anything as long as you declare the name of the template in the comment section in the beginning of the file. This is the case in DustPress too, but the class name that you write for the model should follow a certain pattern. For example if you have a Frontpage template with a filename page-frontpage.php, your class should be named PageFrontpage. The class names are case sensitive. The same goes with custom content type singles, where a single person file should be named single-person.php and the class accordingly SinglePerson.

You still have to declare a name for the templates in the starting comment as you would have done in a traditional WordPress theme as well. This allows user to choose the template file to use with the page and points the DustPress core to load the correct model when loading the page.

The models must be located in the models directory. They could, however, be arranged in any kind of subdirectory tree, so feel free to keep them in whatever structure you like. Note that WordPress also needs to find your template file in order it to work.

Views

The Dust templates are the views of our design pattern. DustPress uses Geniem’s fork of DustPHP library for parsing the Dust templates.

All the data gathered and returned by the public functions of your models are automatically passed to the view. DustPress looks for the Dust templates in the partials directory under the root of the theme. Like models, they could be arranged in any kind of subdirectory hierarchy, so feel free to use whatever suits your needs.

By default the Dust template files follow the naming of the models. single.php should be paired with single.dust. This naming convention can be overwritten in your model by calling the set_template() function. In any of the public functions of the model write $this->set_template(“partial_name”) and it will be used instead of the default template. The .dust file extension is not needed.
