Why Does My Game Activity Table Have Duplicate Entries on Page Refresh?

Double Insertion During Page Load

On a specific gaming page featuring a playable game, a user encountered an unexpected issue. Upon refreshing the page, a MySQL query designed to insert user activity data into a database ("game_activity") was being submitted twice. The query in question was:

$insert_user_activity = mysql_query("INSERT INTO game_activity (user_id,user_full_name,game_id,game_name) values ('$user_id','$full_name','$browser_id','$game_title')");

The Reason for Double Insertion

The issue stemmed from a flawed front controller logic. The page executing the query was being invoked during both valid and invalid requests to the site, including calls to nonexistent resources. This resulted in the query being executed multiple times, causing duplicate insertions.

Resolving the Issue

To rectify the problem, it was necessary to modify the front controller logic. The goal was to prevent the application from running for invalid requests. By implementing this change, the unintended duplicate insertions during site operation would be eliminated.
