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

2

Add function to return daily bread message

Add a function named daily_bread_message() that returns the string 'Today\'s fresh bread: Sourdough'.

Wordpress

<?php
/**
 * Plugin Name: Daily Bread Message
 * Description: Shows a daily bread message
 */

// Add function daily_bread_message here

Define a function that returns the exact string with single quotes inside double quotes.

3

Register shortcode to display the message

Use add_shortcode to register a shortcode named dailybread that calls the function daily_bread_message.

Wordpress

<?php
/**
 * Plugin Name: Daily Bread Message
 * Description: Shows a daily bread message
 */

function daily_bread_message() {
    return "Today's fresh bread: Sourdough";
}

// Register shortcode dailybread here

Use add_shortcode with the shortcode name and function name as strings.

4

Complete plugin with closing PHP tag omitted

Ensure the plugin file ends without a closing ?> tag to follow WordPress best practices.

Wordpress

<?php
/**
 * Plugin Name: Daily Bread Message
 * Description: Shows a daily bread message
 */

function daily_bread_message() {
    return "Today's fresh bread: Sourdough";
}

add_shortcode('dailybread', 'daily_bread_message');

// No closing PHP tag

Do not add a closing ?> tag at the end of the plugin file.
