Purpose

The PHP code snippet you provided is a module that allows the insertion of messages for individual users or groups of users on the home page.

Functionality

  • Retrieves messages from the MESSAGES table where the expiry date is greater than or equal to the current date, the message is not retired, and the message content is not empty.
  • Sorts the messages in descending order of expiry date.
  • Displays the retrieved messages in a designated block on the home page.

Implementation

  • The code uses the db_query() function to query the MESSAGES table.
  • It checks if there are any results returned by the query.
  • If there are results, it iterates through each row and extracts the MESSAGE field.
  • The extracted messages are then displayed within a <div> with the class message_block_home_page.

Benefits

  • Separates the message display logic from the home page code, promoting modularity and maintainability.
  • Enables the administration of home page messages through the database.
  • Provides a designated area for displaying important announcements or new features.

Usage

This module can be included in the home.php file to display the retrieved messages.

Example

<?php
// Include the message module
include('message_module.php');
?>

Note

  • The MESSAGES table should have fields for MESSAGE, EXPIRY DATE, and RETIRED.
  • The message_block_home_page class can be customized to match the desired CSS style for the message block.
