Page Load Query Firing Twice: An Investigation
Users accessing a game page experience an unintended duplication of data when they refresh the page. Upon investigation, they discover a query responsible for logging game activity:
$insert_user_activity = mysql_query("INSERT INTO game_activity (user_id,user_full_name,game_id,game_name) values ('$user_id','$full_name','$browser_id','$game_title')");
Cause:
The root cause of this issue lies in the flawed logic of the front controller. This controller handles all requests to the website, including valid and invalid ones.
Explanation:
When executing the query, the front controller erroneously triggers it for both valid and invalid requests. This results in multiple unnecessary insertions into the database. For example, when the site goes live, this behavior could lead to thousands of false data insertions.
Solution:
To resolve this issue, the front controller's logic must be redesigned. It should now differentiate between valid and invalid requests and execute the query only when appropriate. This ensures that the query is invoked at the correct time and prevents data duplication.
