Practical Applications

Enhancing Website Functionality

Beyond basic edits, a savvy practitioner could employ Code Snippets to handle diverse tasks ranging from security enhancements to performance tuning and user-interaction improvements.

In the examples below, you'll see a few practical snippets: two prebuilt examples bundled with the plugin and some custom enhancements that extend core functionality.

Prebuilt Enhancements:

Disable Admin Bar: Remove the admin toolbar for logged-in users, streamlining the front-end layout.
Display Current Year: Use a ready-made shortcode that dynamically outputs the current year wherever you place it.

Advanced Customizations:

Dashboard Enhancements: Add a bespoke widget and a personalized notice on the Dashboard Home page that surfaces interesting metrics.
Access Control Measures: Restrict access to sensitive plugin menus based on specific user profiles rather than roles.
Branded Visuals: Inject custom CSS to tailor the look of the WordPress interface, providing the potential for limitless modifications to appearance.

Sidebar: Speaking of appearance and custom modifications, it is worth mentioning that the ever-popular CSS Hero plugin provides a dedicated styling solution for WordPress for those specifically interested in front-end manipulation.

1. Prebuilt Snippets

Disable Admin Bar

For a cleaner front-end experience, the following snippet will remove the WordPress admin bar for all logged-in users:

<?php

add_filter('show_admin_bar', '__return_false');

?>

Display Current Year

This snippet defines a shortcode, [current_year], which outputs the current year automatically—no future edits required:

<?php

function current_year_shortcode() {
 return date('Y');
}
add_shortcode('current_year', 'current_year_shortcode');

?>

2. Dashboard Enhancements

You can improve dashboard utility by injecting custom widgets and context-aware messages. The code below creates a Dashboard widget titled 'Case Status Overview' that displays a table with columns for Intake, Active, and Closed statuses. In addition, a dynamic notification greets users when they visit the Dashboard Home page.

Custom Dashboard Widget

Example of a WordPress Dashboard widget titled "Case Study Overview," displaying key metrics and insights.

As you can see from the above image, the following snippet displays a movable widget on the Dashboard>Home page of your WordPress website:

<?php

function custom_dashboard_widget() {

    echo '<style>

    table { width: 100%; border-collapse: collapse; }

    th, td { border: 1px solid #ddd; padding: 8px; text-align: center; }

    th { background-color: #f4f4f4; font-weight: bold; }

    </style>';

    echo '<table>';
    echo '<tr><th>Intake</th><th>Active</th><th>Closed</th></tr>';

    $entries = [
        ['2025-05-10 14:30', 'Yes', 'No'],
        ['2025-05-11 09:45', 'Yes', 'No'],
        ['2025-05-12 12:15', 'No', 'Yes'],
        ['2025-05-13 16:20', 'Yes', 'No'],
        ['2025-05-14 08:50', 'No', 'Yes'],
    ];

    foreach ($entries as $entry) {
        echo '<tr>';
        foreach ($entry as $value) {
            echo '<td>' . esc_html($value) . '</td>';
        }
        echo '</tr>';
    }

    echo '</table>';
}

function add_custom_dashboard_widget() {
    wp_add_dashboard_widget('custom_dashboard_widget', 'Case Status Overview', 'custom_dashboard_widget');
}

add_action('wp_dashboard_setup', 'add_custom_dashboard_widget');

?>

Custom Dashboard Notification

Example of a WordPress Dashboard notification message personalized to the user, showing tailored alerts or recommendations.

As you can see from the above image, the following snippet displays a dismissible success notice on the Dashboard>Home page of your WordPress website, addressing each user by their username:

<?php
function custom_dashboard_notification() {
    global $pagenow;
    // Show the notice only on the Dashboard > Home page
    if ($pagenow === 'index.php') {
        echo '<div class="notice notice-success is-dismissible">
        <p>Hello ' . esc_html(wp_get_current_user()->display_name) . ', this is a notification example.</p>
        </div>';
    }
}
add_action('admin_notices', 'custom_dashboard_notification');
?>

3. Access Control Measures

Use this snippet to compare the current visitor's username or email against an approved set; if there's no match, it removes the Code Snippets menu item from the WordPress Dashboard sidebar:

<?php

function restrict_code_snippets_access() { 
	$allowed_user = 'YOUR_USERNAME'; // Replace with actual username
	$allowed_email = 'YOUR_EMAIL@YOUR_SITE.COM'; // Replace with actual email

	$current_user = wp_get_current_user();

	// If user is NOT authorized, remove menu & prevent direct access
	if ($current_user->user_login !== $allowed_user || $current_user->user_email !== $allowed_email) {
		remove_menu_page('snippets'); // Hide main menu item
		remove_submenu_page('snippets', 'snippets'); // Hide submenu items (main page)
		remove_submenu_page('snippets', 'settings'); // Hide Settings page (adjust if needed)

		// Block direct URL access to the snippets page
		if (isset($_GET['page']) && $_GET['page'] === 'snippets') {
			wp_die('<h1>Access Denied</h1><p>You do not have permission to view this page.</p>', 'Access Denied', ['response' => 403]);
		}
	}
}

// Ensure it runs on admin load
add_action('admin_menu', 'restrict_code_snippets_access', 999);

?>

4. Branded Visuals

Finally, inject CSS to restyle your website or (in this case) the interface—for example, below we change the sidebar menu backgrounds to blue, indicating how you can use your brand's primary hue for consistent theming:

<?php
function custom_admin_sidebar_background() {
    echo '<style>
    #adminmenu li.menu-top {
        background-color: #005a9c !important; /* Medium Electric Blue */
    }
    </style>';
}
add_action('admin_head', 'custom_admin_sidebar_background');
?>

In reviewing these examples, you've seen how the Code Snippets plugin can enhance your WordPress site in multiple ways. Whether you use the prebuilt snippets for a quick solution or dive into custom dashboard enhancements and access control, each snippet demonstrates a unique opportunity to streamline and secure your site's functionality.

While these examples may be a foundation for inspiration, imagine taking this approach even further.

In our next section, we explore Code Snippets' abilities to build static and dynamic data tables—integrating external data sources to present live, actionable insights embedded on your site.

This advanced use case illustrates another creative application for the plugin, where simple PHP snippets unlock interesting data management capabilities.

Let's investigate how to deploy a dynamic solution for managing and displaying information on your WordPress site.

Getting the hang of the Code Snippets plugin can significantly impact WordPress developers who rely on custom code injections. It facilitates the efficient management of custom code snippets and can be particularly helpful for testing.

Advanced Intention

Ruminations of Explicit Expression

Having explored some of the plugin's prebuilt snippets and potential for custom enhancements earlier, let's pivot to a practical demonstration of data table integration(s) using:

A Static Data Table that displays the Canadian Provincial Tax Rates.
A Dynamic Data Table showcasing ad rates, which is updated based on user input via a form.

Static Data Table: Canadian Tax Rates

For an example of a table that might deserve manual updating, we begin with a static Canadian Tax Rate table. This table shows sales taxation information for every province with the following columns:

Province
Provincial Tax Rate
Federal Tax Rate
Total Tax Rate

Tables like this can be a useful quick reference when consulting tax rates while generating invoices. Since it is manually updated, its content remains consistent until an intentional change is applied. You can view the static table embedded below:

Key points about the static table:

Delivers a stable reference that changes only when you manually update it.
Ideal for information like tax rates or any data that changes infrequently.

Dynamic Data: Daily Bid Rate Table

Next, we introduce the dynamic bid rate table to present real-time informational updates. This scenario calls for user-tailored, creative price bids across various categories, advertisers, and payout models such as CPM, CPC, and CPL.

User inputs are provided via an associated Google Form, while the data is captured and stored in a Google Sheet. The dynamic table is embedded below to visualize your data changes after form submission.

Notice of Participation: This section is interactive (and entirely voluntary), so consider the following before proceeding. Do not click the refresh button on the Dynamic Data Table yet. First, input your changes in the associated Google Form by clicking the 'Open Form' button below and finalizing your submission. Once complete, close the modal (the form window) and refresh the table data to view the results of your amendments.

Clicking on the following button opens a modal window where the Google Form is embedded. This form allows you to modify advertiser bid rates, and the changes get reflected in the dynamic table below after clicking the table's refresh button:

Open Google Form

Instructions

1) First select the Category of advertisement you wish to make changes to.

2) Then select an Advertiser whose rates you would like to adjust.

3) Input your price changes in the CPM, CPC, and CPL fields (a valid number from 0-99 is required).

4) Once submitted, close this window and click the 'Refresh' button in the dynamic data table.

Note: The submission data from this form is captured purely for educational purposes.

Kindly note that the Google Form intake is completely anonymous for the intents of this exercise and thus does not request your consent for anything nor does it require you to login to your Google profile to complete submission.

Red Alert: The tables are embedded, and occasional caching on the parent site may delay updates. If the dynamic table data isn’t refreshed after clicking the button, try opening the page in a private tab and using the table's refresh button again to view the latest changes.

Highlights of the dynamic implementation:

Input & Updates: When refreshed, the table reflects changes based on data submitted through the form.
User Participation: A modal (triggered by the 'Open Form' button) provides an interface for entering updated bid rates.
Integration Complexity: While the basic concept is simple, implementing such a system requires API keys, adjustments in Google Cloud Console, and some work with Google App Script on the backend.

Wrapping Up Use Cases

These examples highlight two approaches to handling data tables with the Code Snippets plugin from within WordPress native:

The Static Table offers a controlled, manually updated set of data—ideal for scenarios where information such as reference data persists.
The Dynamic Table showcases a strategy for leveraging external data sources and user input to produce an interactive, real-time table. Doing this adds an element of responsive data presentation without extensive backend changes.

While the technical setup for the dynamic table involves external steps, it further illustrates the possibility of extending WordPress functionality beyond the basics of content display.

Ultimately, these use cases demonstrate that with ingenuity and targeted snippets, you can create robust data solutions that meet specific business needs.

Conclusion

Bringing It All Together

By now, you've seen how the Code Snippets plugin can fit into every stage of your WordPress workflow—from quick PHP tweaks in the Dashboard to full data integrations that pull in external sources. Rather than editing theme files or building a custom plugin, you can manage all your code fragments in one place, organize them with tags, and rely on built-in safeguards when something goes awry.

Before you go, here's a concise recap of the key ideas we've covered so far:

Core Functionality: Execute snippets in-dashboard, deploy across a Multisite network, and embed via shortcodes or builder widgets.
Efficiency Enhancements: Bundle snippets into external stylesheets, automate one-off tasks with run-once snippets, and synchronize your library through the Cloud.
Troubleshooting Support: Use Safe Mode to pause all snippets and isolate issues without impacting your live site.
Everyday Snippets: Disable the admin bar, generate a dynamic current-year shortcode, and add custom dashboard widgets or notices.
Access & Appearance: Control menu visibility based on user credentials and apply branded CSS to the admin interface.
Data Table Integrations: Embed static reference tables for manual updates and build dynamic tables that refresh via form submissions.

These examples illustrate the simplicity of small-scale modifications and the potential for more advanced, interactive features—no standalone plugin required. As you explore further, consider adapting one of the prebuilt snippets to your site, then move on to creating a custom widget or data table. Over time, this collection of snippets will evolve into a personalized toolkit, tailored precisely to your development needs.

Ultimately, this utility offers a clear path to cleaner, more maintainable customizations. With a structured approach—backing up in JSON, grouping by tags, and using Safe Mode—you can expand your site's capabilities confidently and efficiently.

We hope this guide sparks ideas for your next project and demonstrates how the Code Snippets plugin can enable complex, data-driven solutions within WordPress.
