Variablen werden nicht eingelesen, wenn Anweisung in PHP

Ich versuche, ein Formular zu generieren, in einem XML-Dokument, aber der Code nimmt weiterhin die sonst Option "Bitte stellen Sie sicher, dass Sie die Felder korrekt ausgefüllt." in der Datei registration.php, wenn ich die Variablen richtig geliefert habe. Es gibt 3 Abschnitte: HTML, Javascript und PHP. Der Ausgang Ich erhalte istVariablen werden nicht eingelesen, wenn Anweisung in PHP

JAVASCRIPT müssen innen '' Tags und sollte eigentlich auch in der ' ....' Tags sein – RiggsFolly

Sie können mehrere Felder platzieren innerhalb eines 'isset' zu testen, ob sie alle UND testet 'isset ($ _ GET [" Vorname "], $ _GET [" Nachname "], $ _GET [" Passwort "], $ _GET [" E-Mail "])' – RiggsFolly

Ich glaube, Sie einen Schlüssel Gleichen sind vermisst hier anmelden (innen registerCustomer()-Funktion):

"...firstname=" + firstname + "&lastname" + lastname + "&password="

Kontrast mit:

"...firstname=" + firstname + "&lastname=" + lastname + "&password="

Dies bedeutet, Der GET-Index lastname wird niemals festgelegt.
