How Can I Ensure Successful MySQL Data Modification and Return Appropriate Feedback in PHP?

Determining Successful MySQL Query Execution for Database Table Data Modification

When performing database operations, it is crucial to verify whether a query has successfully modified table data. In this case, PHP code executes a query to delete an article from a database and returns a string response to a JavaScript function that updates the page via AJAX. The goal is to return "false" if the query fails.

Incorrect Attempt: Checking Query Preparation Only

The provided PHP code segment attempts to check if the SQL statement is prepared correctly but does not determine if the record is successfully deleted. To address this issue, the code should be updated to check the number of affected rows by the query.

Correct Approach: Verifying Affected Rows

The corrected code segment below checks whether any rows were affected by the query and returns "true" if at least one row was deleted, or "false" otherwise:

...
echo ($delRecord->affected_rows > 0) ? 'true' : 'false';
$delRecord->close();

Note: This approach assumes the JavaScript code correctly handles the string response. If issues arise in the JavaScript portion, more details would be required for assistance.
