Diana GreenConnect

Diana GreenConnect is a WordPress plugin that provides a Gutenberg block to seamlessly integrate the powerful DianaWidget Activity Transit Planner into your WordPress pages and posts. It allows users to plan public transport to and from activities with specific time constraints like start times, end times, and duration.

This plugin acts as a wrapper for the DianaWidget, a sophisticated JavaScript library designed for activity-based transit planning. By using the “Diana GreenConnect Widget” block, you can easily embed this functionality into your content, allowing your site visitors to:

• Find transit connections to a predefined activity.
• Specify their starting location with autocomplete suggestions.
• Select a date for their travel using an adaptive calendar.
• View connection results with clear timelines and transport modes.

The plugin handles secure API authentication with Zuugle Services by allowing administrators to store Client ID and Client Secret in WordPress settings. These credentials are then used server-side to fetch an API token, which is passed to the widget. Each block instance can be configured with unique activity details directly within the WordPress editor.

Features

• Gutenberg Block & Shortcode: Easily add the widget anywhere using the block editor or a flexible shortcode for use in the Classic Editor, page builders, or theme files.
• Secure API Credential Management: Store your Zuugle Services Client ID and Client Secret securely in WordPress settings. API tokens are fetched and handled server-side.
• Customizable Activity Parameters: For each block instance, you can configure:
  • Activity Name and Type
  • Start and End Locations (coordinates or address)
  • Display Names for locations
  • Earliest and Latest Start/End Times for the activity
  • Activity Duration
  • Timezone and Language
  • Custom labels for start/end times
  • Multiday and date override settings
• Dynamic Widget Loading: The widget script is loaded from the official CDN.
• Sharing: Allows users to share their planned journey via a unique link.
• Multiple Widget Instances: Supports multiple Diana GreenConnect blocks on a single page, each with its own configuration.
• Responsive Design: Leverages the responsive capabilities of the core DianaWidget.

About the DianaWidget JavaScript Library

The core functionality is provided by the DianaWidget, a standalone JavaScript library. For more detailed information about the widget’s features, its own configuration options (which this plugin exposes), styling, and architecture, please refer to its GitHub repository:
https://github.com/zuugle-services/DianaWidget

Configuration

1. Getting Your API Credentials

To use the Diana GreenConnect widget, you first need a Client ID and Client Secret. These are used to securely connect to the Zuugle Services API.

1. Register on the Dashboard: Go to the zuugle-services.com dashboard and sign up for an account.
2. Application Creation: Once your registration is complete, an “Application” will be created for you in the Zuugle Services backend.
3. Find Your Credentials: Log in to your dashboard and navigate to the API credentials or application settings section. There you will find your unique Client ID and Client Secret.

The Client ID is a public identifier, but the Client Secret is confidential and must be kept secure. This plugin stores it safely in your WordPress database and never exposes it to the public.

2. Plugin Setup

Once you have your credentials:

1. Navigate to Settings > Diana GreenConnect in your WordPress admin area.
2. Enter your Client ID and Client Secret into the respective fields.
3. Save the settings. Your plugin is now ready to use.

How to Use

Using the Gutenberg Block

1. Add the Block:
   • Open a page or post in the WordPress block editor.
   • Click the + icon to add a new block.
   • Search for “Diana GreenConnect Widget” and select it.
2. Configure the Block:
   • With the block selected, use the Inspector Controls (sidebar on the right) to set the specific details for the activity.
3. Save and View: Save your page/post. The Diana GreenConnect Block will appear on the frontend.

Using the Shortcode

You can embed the widget using the [diana_greenconnect_widget] shortcode. This is ideal for the Classic Editor, page builders (like Elementor or Divi), or widget areas.

All attributes from the Gutenberg block are available. Convert the attribute name to all lowercase. For example, activityName becomes activityname.

Example:
[diana_greenconnect_widget activityname=”Museum Visit” activitydurationminutes=”120″ activitystartlocation=”Museum Address” activitystartlocationtype=”address”]

Important: For the user start location caching to work with a shortcode, you must provide a unique and stable widgetid.

Example with a stable ID:
[diana_greenconnect_widget widgetid=”main-museum-widget” activityname=”Museum Visit” …]

Example of how to use this function:

You can also render the Diana GreenConnect Widget block programmatically within your PHP code using the helper function diana_greenconnect_get_block_html().

Example:

 'main-sidebar-hiking-widget',

    // Required
    'activityName'                     => 'Marktschellenberger Eishöhle im Untersberg',
    'activityType'                     => 'Hiking',
    'activityStartLocation'            => '47.72620173410345, 13.042174020936743',
    'activityStartLocationType'        => 'coordinates',
    'activityEndLocation'              => '47.70487271915757, 13.038710343883247',
    'activityEndLocationType'          => 'coordinates',
    'activityEarliestStartTime'        => '08:00:00',
    'activityLatestStartTime'          => '14:00:00',
    'activityEarliestEndTime'          => '10:00:00',
    'activityLatestEndTime'            => '20:00:00',
    'activityDurationMinutes'          => '300',

    // Optional
    'activityStartLocationDisplayName' => 'Untersbergbahn Talstation',
    'activityEndLocationDisplayName'   => 'Eishöhle, Marktschellenberg',
    'timezone'                         => 'Europe/Vienna', // Set timezone in which all config times are given

    'overrideUserStartLocationType'    => 'address',
    'displayStartDate'                 => null,
    'displayEndDate'                   => null,
    'destinationInputName'             => 'Destination Input Placeholder',
    'containerMaxHeight'               => '650px',
    'hideOverriddenActivityStartDate'  => true,

    // Multiday parameters
    'multiday'                         => false,
    'overrideActivityStartDate'        => "2025-05-20", // Can also be used for single-day date
    'overrideActivityEndDate'          => "2025-05-25",
    'activityDurationDaysFixed'        => 2,

    // Caching & Sharing parameters
    'cacheUserStartLocation'           => true,
    'userStartLocationCacheTTLMinutes' => 15,
    'share'                            => true,
    'allowShareView'                   => true,
    'shareURLPrefix'                   => '',

    // ClientID and ClientSecret are typically managed by the plugin's settings page.
    // Only include them here if you need to override for a specific instance.
    // 'clientID' => 'your_client_id_override',
    // 'clientSecret' => 'your_client_secret_override',
];

$widget_info = diana_greenconnect_get_block_html( $my_widget_attributes );

// Output the HTML (e.g., in a template file or via a shortcode)
echo $widget_info['html'];
?>

When using this function, providing a stable widgetId is crucial for the caching feature to work correctly.

External Services

This plugin connects to external services provided by Zuugle Services GmbH to provide its transit planning functionality.

• DianaWidget JavaScript Library: The core functionality of this plugin is provided by the DianaWidget, a JavaScript library that is loaded from a Content Delivery Network (CDN) at https://diana.zuugle-services.net/dist/DianaWidget.bundle.js. This script is loaded on pages where the Diana GreenConnect block is used to display the transit planning widget.

• Zuugle Services API: To function, the widget needs to communicate with the Zuugle Services API, which has its main endpoint at https://api.zuugle-services.net. This plugin securely handles the authentication with this API.

  • What data is sent and when:
    • To obtain an access token, the plugin sends a Client ID and Client Secret (which are configured in the plugin’s settings) to the token endpoint at https://api.zuugle-services.net/o/token/. This happens on the server-side when a user visits a page containing the widget and a valid token is not already cached. No user data is sent in this step.
    • When a user interacts with the widget to find transit connections, the widget sends the user-specified starting location, the pre-defined activity location, and the selected date and time to the Zuugle Services API to retrieve transit information.
  • Terms and Privacy:
