Hilfe für Fehlerabfang gesucht

Hi @ all!

Ich hab ein LogIn-Script gebastelt was auch hervorragend funktioniert, die Eingabefehler des Users fängt er auch wunderbar ab (also bis jetzt, ob er überhaupt was eingegeben hat). Nur möchte ich, das er die Fehler-Strings (also z.B. "Passwort nicht eingegeben" oder "Nick nicht eingegeben") auf einer neuen Seite ausgibt, und nicht unter dem LogIn-Formular. Anbei hab ich mal das Script angehängt. Wär schön, wenn da einer helfen könnte!

Achso, das ist jetzt nicht direkt der LogIn, das ist die Registrierung eines neuen Users...

Dann musst Du den PHP-Code zur Überprüfung der Daten über die Ausgabe des HTML-Codes setzen und im Fehlerfall anderen HTML-Code ausgeben und danach abbrechen. Somit wird der HTML-Code für das Formular nicht gesendet und es sieht so aus, als ob die Fehlermeldung auf "einer neuen Seite" erscheint.

Ja, wie jetzt?!
Wie wärs, wenn du einfach nur den Fehler ausgibst und nicht noch das ganze Formular:

ja, fiel mir grad noch ne frage ein:

Ich speicher die registrierung ja in ner datenbank. Jetzt hab ich noch was gecoded, womit der eingeloggte User seine eigenen daten verändern kann. dafür hab ich das Registrierungsformular nur etwas umgebaut. Jetzt hab ich aber das Problem das er die neuen daten in nem neuen datensatz speichert. ich hab 'id' als primärschlüssel gesetzt und dachte dann an folgendes, damit er es in die richtige ID einspeichert:
