Aktualisieren/Hinzufügen neuer Datensatz funktioniert nicht

Ich benutze dieses Tutorial (http://www.killersites.com/community/index.php?/topic/3064-basic-php-system-view-edit-add-delete-records-with-mysqli/) und ich folgte jedem Schritt erforderlich, um neue Datensätze in die Datenbank zu erstellen, aber ich kann nicht aktualisieren/bearbeiten meine Datenbank erfolgreich zu aktualisieren. Ich weiß, dass der Code nicht für html5 ist, aber ich werde das später beheben. Zusätzlich können Sie & löschen löschen.Aktualisieren/Hinzufügen neuer Datensatz funktioniert nicht

Was mache ich falsch? Warum funktioniert es nicht? Jede Hilfe wird sehr geschätzt.

Auch ist meine Tabelle wie folgt strukturiert,

Table: supplyDetails 
Columns: 
id int(11) AI PK 
localAuthority varchar(50) 
supplyRef varchar(50) 
supplyName varchar(50) 
estimatedDailyWater varchar(10) 
numberOfConsumers varchar(45) 
dateOfAssessment date 
mitigatedRating varchar(2) 
finalRating varchar(2)

Hier ist meine records.php

<?php 
/* 
Allows the user to both create new records and edit existing records 
*/ 

// connect to the database 
include("connect-db.php"); 

// creates the new/edit record form 
// since this form is used multiple times in this file, I have made it a function that is easily reusable 
function renderForm($localauth = '', $supref = '', $supname = '', $waterusage = '', $numofconsum = '', $dateofassess = '', $mitrating = '', $frating = '', $error = '', $id = '') {

LÖSUNG für zukünftige Referenzen.

OK, ich schaffte es, eine Antwort zu finden. Ich implementierte eine richtige Fehlerbehandlung, dank der oben genannten Vorschläge, in meine connect-db.php Datei

mysqli_report(MYSQLI_REPORT_ALL) ; 
try { 
$mysqli = new mysqli($server, $user, $pass, $db); 

// show errors (remove this line if on a live site) 

} catch (Exception $e) { 
    echo $e->getMessage(); 
}

Nach Hantieren einen Datensatz mit der Bearbeitung, war ich einen Fehler in Bezug auf den Zeitpunkt empfangen, also habe ich das Datum Geben Sie meine MySQL-Tabelle und von Datum -> Varchar (30). (30 kann eine Menge für ein Datum, aber meh)

Dann änderte ich meinen Code ein wenig, jene Änderungen zu reflektieren,

$dateOfAssessment = htmlentities($_POST['dateOfAssessment'], ENT_QUOTES); 
$displaydate = date("D d M Y", strtotime($dateOfAssessment));

Und änderte auch die $stmt zu

if ($stmt = $mysqli->prepare("UPDATE supplyDetails SET localAuthority = ?, supplyRef = ?, supplyName = ?, estimatedDailyWater = ?, numberOfConsumers = ?, dateOfAssessment = ?, mitigatedRating = ?, finalRating = ? WHERE id=?")) { 
$stmt->bind_param("ssssssssi", $localAuthority, $supplyRef, $supplyName, $estimatedDailyWater, $numberOfConsumers, $displaydate, $mitigatedRating, $finalRating, $id); 
$stmt->execute(); 
$stmt->close(); 
}

Und die Ausgabe ist so etwas wie folgt:
