Probleme mit captcha und Internet Explorer

sugar · 8. August 2011

Ich habe das Problem das folgendes Formular eigentlich sehr gut funktioniert. Nur bei manchen Anmeldungen die anscheinend über Internet Explorer ausgeführt werden, funktioniert das Captcha nicht. Ich habe schon verschiedenen Captcha Scripte eingebaut, also denke ich nicht, dass es direkt dran liegt. Das Formular läuft über eine SSL Verbindung. Fehlermeldungen gibt es sonst keine. Bei den Anmeldungen wo es nicht funktioniert erscheint eben immer wieder die Aufforderung den richtigen Sicherheitscode einzugeben. Ich habe es in verschiedenen Versionen von IE getestet nur lustigerweise kann ich den Fehler nicht rekonstruieren! Hier mal der Code:

PHP:

session_start(); 
include "lang/english.php"; 
require_once "includes/capya.php";
$date = date("d.m.y"); 


foreach($_POST as $k=>$v){
	htmlentities($v);
}

//Auslesen der Dateien
				$price=$_POST['price'];
				$_SESSION['price'] = $price;
				$Titel=$_POST['Titel'];
				$_SESSION['Titel'] = $Titel;
				$datum=$_POST['date'];
				$_SESSION['date'] = $date;
				$Anrede=$_POST['Anrede'];
				$_SESSION['Anrede'] = $Anrede;
				$Firma=$_POST['Firma'];
				$_SESSION['Firma'] = $Firma;
				$Institut=$_POST['Institut'];
				$_SESSION['Institut'] = $Institut;
				$Vorname=$_POST['Vorname'];
				$_SESSION['Vorname'] = $Vorname;
				$Nachname=$_POST['Nachname'];
				$_SESSION['Nachname'] = $Nachname;
				$initials=$_POST['initials'];
				$_SESSION['initials'] = $initials;
				$Strasse=$_POST['Strasse'];
				$_SESSION['Strasse'] = $Strasse;
				$Strasse2=$_POST['Strasse2'];
				$_SESSION['Strasse2'] = $Strasse2;
				$PLZ=$_POST['PLZ'];
				$_SESSION['PLZ'] = $PLZ;
				$Ort=$_POST['Ort'];
				$_SESSION['Ort'] = $Ort;
				$Land=$_POST['Land'];
				$_SESSION['Land'] = $Land;
				$Telefon=$_POST['Telefon'];
				$_SESSION['Telefon'] = $Telefon;
				$Fax=$_POST['Fax'];
				$_SESSION['Fax'] = $Fax;
				$Type=$_POST['Type'];
				$_SESSION['Type'] = $Type;
				$Remarks=$_POST['Remarks'];
				$_SESSION['Remarks'] = $Remarks;
				$Zahlungsweise=$_POST['Zahlungsweise'];
				$_SESSION['Zahlungsweise'] = $Zahlungsweise;
				$Kreditkarte=$_POST['Kreditkarte'];
				$_SESSION['Kreditkarte'] = $Kreditkarte;
				$Kartennummer=$_POST['Kartennummer'];
				$_SESSION['Kartennummer'] = $Kartennummer;
				$Expiration_date=$_POST['Expiration_date'];
				$_SESSION['Expiration_date'] = $Expiration_date;
				$Datenschutz=$_POST['Datenschutz'];
				$_SESSION['Datenschutz'] = $Datenschutz;
				$Event=$_POST['Event'];
				$_SESSION['Event'] = $Event;
				$Kopie=$_POST['Kopie'];
				$_SESSION['Kopie'] = $Kopie;
				$capya=$_POST['capya'];
				$guests=$_POST['guests'];
				$_SESSION['guests'] = $guests;
				$E_Mail=$_POST['E_Mail'];
				$_SESSION['E_Mail'] = $E_Mail;

Frag oder schau doch als erstes mal beim Autor des Scripts nach.
Woher weißt du denn von den Fehlern?

SE · 8. August 2011

Und woher weist du das diese Fehler NUR beim IE auftreten ?

sugar · 8. August 2011

Weil sich verschiedene Leute versucht haben zu registrieren weiß ich das mit dem IE. Diese haben angegeben, Sie haben versucht sich mit dem IE zu registrieren. Wie gesagt, grundsätzlich geht es, nur bei manchen nicht.

Könnte es etwas mit den Sicherheitseinstellungen im IE zu tun haben?

erik s. · 9. August 2011

Dann frag doch mal die Leute, welche IE Version sie benutzt haben und ob sie Cookies akzeptieren oder nicht.
Wenn die Session-ID per Cookie übergeben wird und keine Cookies akzeptiert werden, dann weiß die aufgerufene Seite auch nicht, welche Session sie fortsetzen soll und beginnt eine neue. Damit fliegen auch deine Daten (wie z.B. der korrekte Captcha-Code, der mitgegeben werden sollte) raus.
