Undefined index
Tot nu toe lijkt het me allemaal nog heel moeilijk.
1 van de problemen die ik echt niet snap (OOK AL heb ik een handboek gevolgd!) is het volgende:
Notice: Undefined index: firstname in C:\xampp\htdocs\contact.php on line 14
Notice: Undefined index: sent in C:\xampp\htdocs\contact.php on line 16
Notice: Undefined index: sent in C:\xampp\htdocs\contact.php on line 21
Notice: Undefined index: sent in C:\xampp\htdocs\contact.php on line 28
Notice: Undefined index: sent in C:\xampp\htdocs\contact.php on line 35
Notice: Undefined index: sent in C:\xampp\htdocs\contact.php on line 42
Deze error krijg ik in verband met mijn contact formulier (en mijn excuse, ik weet niet hoe ik de lijn-nummers erbij kopieer):

Probeer de dingen die daar aangegeven worden aan te passen. Lukt het dan nog niet dan kunnen we je vast verder helpen.
Niet meer gebruiken dus.
Zie de preg_match() op php.net.

Waarom zou je dat willen?
Kijken of iets is gePOST doe je met:
if($_SERVER['REQUEST_METHOD'] == 'post')
En nutteloos nieuwe variabelen aanmaken kost alleen maar extra geheugen.
