Creating Administrative Panels on WordPress Using PHP

WordPress is a popular platform for creating and managing websites. One of the powerful tools it provides to developers is the ability to create custom administrative panels. In this article, we will explore how to use the PHP programming language to create custom administrative panels for managing your site’s content and settings.

Step 1: Getting Started

Before we begin, make sure you have WordPress installed and have basic knowledge of PHP.

Step 2: Creating a Plugin

To start, let’s create a new plugin that will contain our administrative panel. Create a new directory in the wp-content/plugins folder and name it, for example, custom-admin-panel.

Step 3: Main Plugin File

Inside the custom-admin-panel directory, create a file named custom-admin-panel.php. This file will be the main file of your plugin.

<?php
/*
Plugin Name: Custom Admin Panel
Description: Create a custom administrative panel for site management.
Version: 1.0
Author: Your Name
*/

// Your plugin code will go here
?>

Step 4: Adding the Administrative Panel

Next, let’s add a custom administrative panel to the WordPress admin page.

function custom_admin_panel_menu() {
    add_menu_page(
        'Custom Admin Panel',  // Page title
        'Custom Panel',        // Menu title
        'manage_options',      // Role that has access to the page
        'custom-admin-panel',  // Unique page identifier
        'custom_admin_panel_page', // Function to display content
        'dashicons-admin-generic', // Menu icon
        20 // Menu position
    );
}
add_action('admin_menu', 'custom_admin_panel_menu');

Step 5: Creating the Panel Page

Now, let’s create a function to display the content of our administrative panel.

function custom_admin_panel_page() {
    ?>
    <div class="wrap">
        <h2>Custom Administrative Panel</h2>
        <!-- Your HTML and forms will go here -->
    </div>
    <?php
}

Step 6: Adding Functionality

Let’s add an example of functionality, such as a form for changing settings.

function custom_admin_panel_page() {
    ?>
    <div class="wrap">
        <h2>Custom Administrative Panel</h2>
        <form method="post" action="">
            <?php wp_nonce_field('custom_admin_panel_nonce', 'custom_admin_panel_nonce'); ?>
            <table class="form-table">
                <tr valign="top">
                    <th scope="row">Setting 1</th>
                    <td><input type="text" name="setting_1" value="<?php echo esc_attr(get_option('setting_1')); ?>" /></td>
                </tr>
                <!-- Add additional settings here -->
            </table>
            <p class="submit"><input type="submit" class="button-primary" value="Save Changes" /></p>
        </form>
    </div>
    <?php
}

Step 7: Handling Form Data

Add a function to handle form data and save settings.

function custom_admin_panel_save_settings() {
    if (isset($_POST['custom_admin_panel_nonce']) && wp_verify_nonce($_POST['custom_admin_panel_nonce'], 'custom_admin_panel_nonce')) {
        update_option('setting_1', sanitize_text_field($_POST['setting_1']));
        // Handle other settings
    }
}
add_action('admin_init', 'custom_admin_panel_save_settings');
