Fout afhandeling registratie formulier werkt niet.
Ik ben bezig met een login/registratie formulier. Het is een bestaand script maar er was bijna geen controle op de invoer.
Hiervoor heb ik een ander script gebruikt. Aan de voorkant gaat alles goed ook de controle of het ingevoerde email adres al bestaat.
Maar aan de achterkant werkt het niet. De velden die zijn ingevuld of ze nou fout of goed zijn die worden gelijk ingevoerd in de database. Ik zelf denk dat het met het aller laatste stukje code te maken heeft.
Dit is het registratie formulier met de toegevoegde controle:

Bij het origineel staat dit stukje
Code (php)
Helemaal boven aan. Als ik dat hier doe dan krijg ik gelijk de melding dat het email adres al bestaat nog voor ik iets heb ingevuld. Heeft iemand een idee waarom het gelijk de datbase ingeschreven wordt of waarom er gelijk de melding komt dat het email adres al bestaat als dit stukje boven aan staat?

Gelieve in het vervolg bij code de [code][/code]-tags gebruiken.
Hier kan je meer lezen over de mogelijke opmaakcodes.
Alvast bedankt!

Gebruik gewoon de php functie filter_input() met het juiste filter om een email adres te herkennen.
verder wemelt je code van de stripslashes() waar je htmlspecialchars() bedoelt.
Je preg_match functies zijn raar: ik denk dan je ~[<>]~ bedoelt? (al blijft het matigjes)
En tenslotte:
vermoedelijk wil je alleen register.php includen als !isset($errors)
