Shortcode Module

The Fulcrum Custom Shortcode Module makes your job easier for adding shortcodes to your project. Pass it a configuration, build your view file, and it handles the rest for you.

Features

• Registration is handled for you.
• Merges the user-defined atts with the defaults you specify, i.e. handles shortcode_atts for you.
• Renders the view file you specify in the configuration.
• Use the built-in Shortcode class or specify a custom one within your configuration file.
• Stores in Fulcrum's Container - when added, automatically stores it in the Container for global usage.

Installation

The best way to use this component is through Composer:

composer require wpfulcrum/shortcode

Dependencies

This module requires:

• at least PHP 5.6
• WordPress 4.8+

Configuring a Shortcode

This module, as with all Fulcrum modules, is configuration driven as part of the ModularConfig design pattern. In your theme/plugin's configuration folder, you will want to create a configuration file. Here is the basic structure of that file:

<?php

return [
    /**
     * Defines whether the shortcode should autoload when registering with Fulcrum.
     *
     * Default is true.
     */
    'autoload'  => true,
    
    /**
     * If you'd like to build your own shortcode class, specify the class name here, such as:
     *
     * Fulcrum\Custom\Shortcode\Shortcode
     *
     * By default, it will use the built-in Shortcode class.
     */
    'classname' => '',

    'config'    => [
        /**
         * Specify the name of the shortcode.  This is the "tag" which is used in the content as: [foo].
         */
        'shortcode' => 'foo',

        /**
         * Set this parameter to `true` when no view file is needed for this shortcode.
         */
        'noView' => false,

        /**
         * Specify the absolute path to this shortcode's view file.
         * The view file contains the HTML that is built for this shortcode.
         */
        'view'      => __DIR__ . '/views/foo.php',

        /**
         * Specify the default attributes for this shortcode.
         */
        'defaults'  => [
            'class' => 'foobar',
        ],
    ],
];

The View File

Shortcodes create HTML that is returned back for inclusion into the content that sent out to the browser. Create a view file for your shortcode.

Example: View File

<p class="<?php echo $this->getClass(); ?>"><?php echo $this->content; ?></p>

Properties Available

The following properties are available for you to use within your view file:

• $this->attributes - Array of attributes after merging the user-defined with the defaults using shortcode_atts.
• $this->content - The content passed into the shortcode, e.g. [foo]This is the content[/foo].

Methods Available

Some common shortcode attributes are id and class attributes. You can use the following methods to get either of these for your view:

• $this->getId() which escapes and returns id="the-id".
• $this->getClass() which escapes and returns the class attribute, e.g. foobar. You can pass a true to it to add a space in front of the class attribute, e.g. $this->getClass() returns foobar.

Making It Work

There are 2 ways to utilize this module:

1. With the full Fulcrum plugin.
2. Or on its own without Fulcrum.

With Fulcrum

In Fulcrum, your plugin is an Add-on. In your plugin's configuration file, you will have a parameter for the serviceProviders, where you list each of the service providers you want to use. In this case, you'll use the provider.post_type.

For example, using our Book configuration above, this would be the configuration:

	'serviceProviders' => [

		/****************************
		 * Custom Post Types
		 ****************************/
		'foo.shortcode' => array(
			'provider' => 'provider.shortcode', // this is the service provider to be used.
			'config'   => FOO_PLUGIN_DIR . 'config/shortcode/foo.php', // path to the shortcode's configuration file.
		),
	],

Without Fulcrum

Without Fulcrum, you'll need to instantiate each of the dependencies and Shortcode. For example, you would do:

new Shortcode(
    ConfigFactory::create(FOO_PLUGIN_DIR . 'config/shortcode/foo.php'), // path to the shortcode's configuration file.
);
