How Can I Verify Successful PDO Inserts in PHP Using Query Feedback?

Checking PDO Insert Success with Query Feedback

When performing an insert operation using PHP Data Objects (PDO), it's crucial to determine whether or not the operation was successful. PDO offers several methods to retrieve feedback regarding the insert.

The PDOStatement->execute() method is used to execute a prepared statement. Upon successful execution, it returns true, indicating that the insert was executed without any errors.

Programmatic Feedback

If you want programmatic feedback beyond the true return value, you can utilize the PDOStatement->errorCode() method. This method returns an error code, or NULL if there are no errors.

By checking the error code, you can determine whether the insert encountered any issues. For example, if the insert failed due to a duplicate record, the error code would indicate a constraint violation or a similar error.

Here's how you can use these methods to check for insert success:

$stmt = $pdo->prepare('INSERT INTO table (field1, field2) VALUES (:field1, :field2)');
$stmt->bindParam(':field1', $field1, PDO::PARAM_STR);
$stmt->bindParam(':field2', $field2, PDO::PARAM_STR);

if ($stmt->execute()) {
    // Insert was successful
} else {
    $errorCode = $stmt->errorCode();
    // Check the error code for specific error details
}
