ik ben bezig met een inlog systeem maar ik krijg steeds de zelfde fout en
weet niet wat er mis is heeft iemand er verstand van en kan die mij
helpen dit is de fout -->
Warning: mysql_error(): supplied argument is not a valid MySQL-Link resource in ******mijn-site******** on line 9

en volgens mij klopt er iets in de code niet:

Code:
$query = "SELECT Wachtwoord FROM members WHERE Gebruikersnaam = '$test_gebruikersnaam'";
$result_id = mysql_query($query) or die(mysql_error($query));
$row = mysql_fetch_row($result_id);


Zelf dacht ik dat die middelste fout was maar kan iemand me aub helpen

je hoeft idd niet de query aan te geven in een mysql_error(); mysql_error weergeeft namelijk automatisch de laatste error!

Die error geeft over het algemeen aan dat er niks geselecteerd is met de query. Is de tabel wel gevuld? Alle variabelen goed ingevuld/opgegeven?

ik moest dus alleen die query weglaten

Ik gok dat je die foutmelding dan nog steeds krijgt, zie mijn post.

Kan ook, maar meestal is de query dan zodanig fout dat hij niks selecteerd, dan geeft hij ook een error.
