Daten werden nicht in meiner Datenbank gespeichert

Question

Ich hoffe, es geht dir gut. Ich habe ein Problem, bei dem ich keine Daten in meine Datenbank einfügen kann. Es gibt mehrere Gründe, warum das passiert, also halte es bitte nicht für eine doppelte Frage. Ich habe meinen Code überprüft. Für eine Tabelle speichert es die Daten aber für diese Tabelle. Es wird angezeigt, dass dieselbe Seite nicht gefunden wurde und keine Daten in der lokalen Datenbank gespeichert sind. Ich hoffe du kannst mir helfen Jungs. Danke im Voraus. :) Hier sind einige nützliche Stücke von Code:

<?php 
include 'Header.php'; 
?> 
<style> 
    #first { 
     //margin-right: 100%; 
     //clear: both; 

    } 
    #first > img { 
     display: inline-block; 
     //float: left; 
    } 
    #first > p { 
     //float: left; 
     display: inline-block; 
     //margin-left: 60px; 
     //margin-bottom: 120px; 
    } 

</style>

Answer 1

Ich stieß auf diese Art von Problem beim Arbeiten auf einer Staging-Site, weil Webhosting verschiedene Arten von Einschränkungen und streng haben kann. Nun ändere ich den Dateinamen zum Beispiel:

Klassenname sollte mit dem Dateinamen übereinstimmen, denn es ist Groß-und Kleinschreibung.

comment.php

class Comment extends DBConn { 

function __construct() { 
parent::__construct(); 
} 

//code here.. 

}
