Geachte PHP'ers
Ik heb een fout in mijn script.
Maar ik weet maar niet wat ik fout doe!! :S
De foutmelding is die ik krijg:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in c:\wamp\www\paginas\forum\handlers\handle_selecttopic.php on line 39
Kan iemand mij de uitleg geven wat ik fout doe ?
<?php
session_start();
?>
<link href="/paginas/css/lettertypen.css" rel="stylesheet" type="text/css" />
<?php
if ($_SESSION['user_ID'] == "")
{
print("<div align=\"center\"><span class=\"xbig\">Je bent niet ingelogd!</span><br /> <br /><span class=\"style4\"><a href=\"/paginas/login.php\">Hier</a> kun je je inloggen</span></div>");
exit;
}
//Informatie uit GET halen.
$topic_name = $_GET['topic'];
$topic_id = $_GET['id'];
$parent1 = $_GET['parent1'];
//verbinding maken met da database!
$dbc = mysql_connect('localhost', '****', '******);
mysql_select_db('knorfski', $dbc);
//Query's aanmaken
$query2 = "select * from forum_inhoud WHERE parent2='$topic_name' order by id DESC";
//Query's uitvoeren
$result2 = mysql_query($query2, $dbc);
