💼 Career

Understanding deployment best practices is essential for WordPress developers and site administrators to maintain stable and secure websites.

1

Create the plugin main file with header

Create a PHP file named proper-deployment.php with the WordPress plugin header including Plugin Name: Proper Deployment and Version: 1.0.

Wordpress

<?php
// Your code here

Need a hint?

The plugin header must start with /** and include Plugin Name and Version.

2

Add a configuration variable for deployment mode

Add a variable called $deployment_mode and set it to the string 'safe' to control how the plugin updates.

Wordpress

<?php
/**
 * Plugin Name: Proper Deployment
 * Version: 1.0
 */

// Your code here

Need a hint?

Define $deployment_mode exactly as shown to control plugin behavior.

3

Write a function to perform safe update hooked to admin_init

Write a function named proper_deployment_update that checks if $deployment_mode equals 'safe'. If yes, it should run safely without errors. Hook this function to the WordPress admin_init action.

Wordpress

<?php
/**
 * Plugin Name: Proper Deployment
 * Version: 1.0
 */

$deployment_mode = 'safe';

// Your code here

Need a hint?

Use global $deployment_mode inside the function and hook it with add_action.

4

Add activation hook to complete setup

Add a function named proper_deployment_activate that runs on plugin activation. Hook it to register_activation_hook using __FILE__ and the function name.

Wordpress

<?php
/**
 * Plugin Name: Proper Deployment
 * Version: 1.0
 */

$deployment_mode = 'safe';

function proper_deployment_update() {
    global $deployment_mode;
    if ($deployment_mode === 'safe') {
        // Safe update logic here
    }
}
add_action('admin_init', 'proper_deployment_update');

// Your code here

Need a hint?

Use register_activation_hook with __FILE__ and your activation function.
