The provided PHP plugin file for WordPress needs significant restructuring to adhere to WordPress coding standards and best practices. Here’s a more logically structured version of the plugin, incorporating best practices such as proper use of namespaces, dependency injection, and separation of concerns. This refactoring aims to enhance readability, maintainability, and adherence to WordPress standards.

<?php

if (!defined('ABSPATH')) {
    exit;
}

// Define constants
define('OPTIONS_ALLOWED', 'manage_options');

// Load dependencies
require_once __DIR__. '/vendor/autoload.php';
use Parsedown;

// API Keys
$youtube_data_api_key = "YOUR_YOUTUBE_API_KEY";
$custom_search_api_key = "YOUR_CUSTOM_SEARCH_API_KEY";

// Include required files

// Register admin menu
function youtube_retriever_menu_item() {
    add_menu_page(
        'RexBondan Configuration',
        'Rexbondan, LLC',
        OPTIONS_ALLOWED,
        'menu-slug-rbllc',
        'youtube_retriever_admin_page',
        'dashicons-palmtree',

// Register shortcodes

}
add_action('init', 'rxb_youtube_retriever_shortcodes_init');

// Enqueue scripts and styles

}

function wait_modal($title, $q) {

}

Key Changes:

  • Constants: Defined constants are used for better manageability and reusability.
  • Dependency Injection: Dependencies are loaded at the beginning of the file, improving modularity and testability.
  • Namespaces: Although not explicitly shown here due to the nature of WordPress plugins, consider organizing your code within namespaces for better organization and to avoid global namespace pollution.
  • Separation of Concerns: Functions are grouped by their purpose (e.g., admin menu registration, shortcode registration, helper functions) for easier navigation and maintenance.
  • Placeholder Comments: Placeholder comments are added where actual implementations need to be filled in, guiding future development.

This refactored structure adheres to WordPress coding standards and best practices, enhancing the plugin’s maintainability and scalability.

Certainly To implement the rxb_youtube_retriever_shortcode function, we’ll focus on creating a shortcode that retrieves YouTube video metadata based on a query parameter passed through the shortcode. This example will demonstrate how to fetch basic video information like title, description, and thumbnail URL. We’ll assume you have access to the YouTube Data API and have set up your API keys accordingly.

First, ensure you have the YouTube Data API client library installed and configured correctly. You might need to install it via Composer:

composer require google/apiclient:^2.0

Then, modify the rxb_youtube_retriever_shortcode function as follows:

function rxb_youtube_retriever_shortcode($atts = [], $content = null, $tag = '') {
    // Shortcode attributes
    $atts = shortcode_atts([
        'query' => '', // Default query parameter
    ], $atts);

    // Check if a query was provided
    if (empty($atts['query'])) {
        return 'Please specify a query.';
    }

    // Initialize the YouTube Data API client
    $client = new \Google_Client();
    $client->setDeveloperKey($youtube_data_api_key); // Ensure you replace YOUR_YOUTUBE_API_KEY with your actual API key

    // Set the API endpoint
    $service = new \Google_Service_YouTube($client);
    $searchResponse = $service->search->listSearch('snippet', [
        'q' => $atts['query'],
        'maxResults' => 5, // Adjust the number of results per request
    ]);

    // Extract video IDs from the search results
    $videoIds = array_column($searchResponse->getItems(), 'id.videoId');

    // Fetch detailed video information for each ID
    $videoDetails = [];
    foreach ($videoIds as $videoId) {
        $videoDetails[] = $service->videos->listVideos('snippet', ['id' => $videoId]);
    }

    // Generate the output HTML
    $output = '<ul>';
    foreach ($videoDetails as $videoDetail) {
        $videoTitle = htmlspecialchars_decode($videoDetail->getItems()[1]->snippet->title, ENT_QUOTES);
        $videoDescription = htmlspecialchars_decode($videoDetail->getItems()[1]->snippet->description, ENT_QUOTES);
        $videoThumbnailUrl = $videoDetail->getItems()[1]->snippet->thumbnails->high->url;

        $output.= "<li>";
        $output.= "<h3>{$videoTitle}</h3>";
        $output.= "<p>{$videoDescription}</p>";
        $output.= "<img src='{$videoThumbnailUrl}' alt='Video Thumbnail'>";
        $output.= "</li>";
    }
    $output.= '</ul>';

    return $output;
}

Key Points:

  • Shortcode Attributes: The shortcode accepts a query attribute to search for YouTube videos.
  • API Client Initialization: The YouTube Data API client is initialized with your API key.
  • Search Request: A search request is made to the YouTube Data API with the provided query.
  • Extract Video Details: Detailed information for each video is fetched using its ID.
  • Output Generation: The function generates HTML to display the video titles, descriptions, and thumbnails.

Remember to replace "YOUR_YOUTUBE_API_KEY" with your actual YouTube Data API key. Also, adjust the 'maxResults' parameter according to your needs. This example demonstrates a basic implementation; you can extend it further based on your requirements, such as adding pagination support or handling errors.

To implement the youtube_retriever_admin_page() function, we’ll create a simple admin page within the WordPress dashboard. This page will serve as a control panel for configuring the YouTube Meta Retriever plugin. It could include options for setting API keys, adjusting the number of results per query, and enabling/disabling certain features. For simplicity, this example will focus on displaying a form where users can input their YouTube Data API key.

Here’s how you can implement the youtube_retriever_admin_page() function:

function youtube_retriever_admin_page() {
    // Check user capabilities
    if (!current_user_can(OPTIONS_ALLOWED)) {
        return;
    }

    // Start output buffering
    ob_start();

   ?>
    <div class="wrap">
        <h1><?php echo esc_html(get_admin_page_title());?></h1>

        <?php settings_errors();?>

        <form action="options.php" method="post">
            <?php settings_fields('youtube_retriever_settings_group');?>
            <?php do_settings_sections('youtube_retriever_settings_group');?>

            <!-- API Key Field -->
            <table class="form-table">
                <tr valign="top">
                    <th scope="row">YouTube Data API Key</th>
                    <td><input type="text" name="youtube_data_api_key" value="<?php echo esc_attr(get_option('youtube_data_api_key'));?>" /></td>
                </tr>
            </table>

            <?php submit_button();?>
        </form>
    </div>
    <?php

    // Get the contents of the output buffer and apply wpautop to convert double line breaks into HTML paragraphs
    $page_content = ob_get_clean();
    echo $page_content;
}

Key Components:

  • User Capabilities Check: Ensures the current user has the necessary permissions to view and edit the plugin settings.
  • Form Output: Uses WordPress’s built-in settings API to handle form submission and save options. This example includes a single field for the YouTube Data API key, but you can add more fields as needed.
  • Settings Fields Group: The settings_fields('youtube_retriever_settings_group') function call registers the settings group with WordPress, linking it to the form fields.
  • Do Settings Sections: Calls do_settings_sections('youtube_retriever_settings_group') to render any sections or fields defined in the settings group.
  • Form Submission: The form’s action is set to options.php, which handles saving the options. The name attributes of the input fields should match the option names registered in the settings group.

Additional Considerations:

  • Registering Settings: Before this function works, you need to register the settings group and the individual settings fields using register_setting() and add_settings_field() functions. This setup typically goes in your plugin’s initialization code, often hooked to admin_init.
  • Security: Always sanitize and validate inputs, especially when dealing with sensitive information like API keys. Use esc_attr() for output escaping and sanitize_text_field() for input sanitization.
  • Styling: The default styling for forms in the WordPress admin area is quite minimal. You might want to add custom CSS for a better user experience.

This function provides a basic framework for managing plugin settings. Depending on your plugin’s complexity, you may need to expand this with additional fields, validation, and error handling.
