How can error handling be improved when using checkboxes to update database records in PHP?

When using checkboxes to update database records in PHP, error handling can be improved by checking if the checkbox is checked before updating the database record. This can prevent errors from occurring if the checkbox is not selected. Additionally, using try-catch blocks can help catch any exceptions that may occur during the database update process. 

// Check if the checkbox is checked before updating the database record
if(isset($_POST['checkbox_name']) && $_POST['checkbox_name'] == 'on') {
    try {
        // Update the database record
        $query = "UPDATE table_name SET column_name = 'value' WHERE id = 'record_id'";
        $result = mysqli_query($connection, $query);
        if(!$result) {
            throw new Exception("Error updating database record");
        }
        echo "Database record updated successfully";
    } catch(Exception $e) {
        echo "Error: " . $e->getMessage();
    }
} else {
    echo "Checkbox not selected";
}
