So aktualisieren Sie PHP-Formular, wenn der Benutzer klicken Sie auf submit-button?
Ich habe ein Formular, dass Daten aktualisiert. Wenn ich auf die Schaltfläche "aktualisieren" aktualisiert die Daten in der Datenbank, zeigt aber die alten Daten in das Formular ein, und ich muss die Seite aktualisieren wieder die aktuellen Daten. Wenn ich die action von der Seite, es hält die Aktualisierung der Daten.
Ich soll die update-Seite um die Daten zu aktualisieren, wenn der Benutzer klickt auf Button "Einreichen".
Bitte sagen Sie mir den Weg, um dieses problem zu überwinden.
Dank
