Probleme Data in Date-Bank zu einsetzen

[liebewinter]

Hallo, Ich habe diese PHP Datei um Form zu Verwalter…

<?php


class ClassProveContakt3 
{

      private $Name;
      private $Email;
      private $Message;
      private $PostOK;
      private $DateTime;
      private $items;
      

 
    function __construct() 
    {

         $this -> ips = $_SERVER['REMOTE_ADDR'];
         $this -> DateTime = date('m/d/Y h:i:s a');  
         $this -> items = ['Name', 'Email', 'Message']; 
          
         $flag = true;
          foreach ( $this -> items as $key ) {  
			           if ( empty ( $_POST[$key] ) )  {
			             $flag = false;    
			           } else {    
			             $this -> $key = trim( filter_var( $_POST[$key], FILTER_SANITIZE_STRING ) );
			            }    
		   }	     
         $this -> PostOk = $flag; 
    }

 
    

  
    function ShowForm() 
    {
?>
      <form  method="POST">
        <label for="name"><b>Name * </b></label>
        <input type="text" id="name" name="Name" value="">
        <label for="email"><b>E-mail * </b></label>
