What potential issue is the user facing with the PHP code provided for displaying the latest post in a forum board?

The potential issue the user is facing with the PHP code provided for displaying the latest post in a forum board is that the query is not ordering the posts by date in descending order, so it may not display the latest post correctly. To solve this issue, you can modify the SQL query to order the posts by date in descending order using the "ORDER BY" clause.

// Original code snippet
$query = "SELECT * FROM posts WHERE forum_id = $forum_id LIMIT 1";

// Modified code snippet to order posts by date in descending order
$query = "SELECT * FROM posts WHERE forum_id = $forum_id ORDER BY post_date DESC LIMIT 1";
