Login form werkt niet
Ik gebruik nu net het DreamWeaver login script maar krijg de melding headers already send.... Heeft iemand een idee hoe dit komt?
Groeten Donny

Over "headers already sent" komt zeer regelmatig een vraag voorbij.
Je loopt al een tijdje rond op dit forum: plaats code aub tussen code-tags.
Heb je in je script echt een php sluiten direct gevolgd door php openen?
$_SERVER['PHP_SELF']; schijnt onveilig te zijn (in formulieren). Laat dan liever leeg.
Code (php)

$loginUsername=$_POST['username'];
$password=$_POST['password'];
$password=$_POST['password'];
is zinloos: waarom zou je dit willen kopiëren? Daarnaast: je controleert nergens of $_POST['password'] wel bestaat.
Verder mis ik nette foutafhandeling bij je query (or die is in ieder geval niet de oplossing).
Donny van Grondelle op 19/12/2012 15:31:06:
Dit is een standaard script van Dreamweaver.
Dreamweaver blijkbaar niet meer gebruiken want de html is niet okee.
<input type="text" id="login" value="" />
Waar is name="..."?
En waar is </form>?
