Cant get past IF statement to connect to database


Recommended Posts

Hello I am creating a simple Discussion Forum, and I cant get past my IF Statement to verify topics exist? Please help?




//check for required info from the query string

if (!$_GET[topic_id]) {

header("Location: topiclist.php");




//connect to server and select database

$link = mysql_connect('votpservicescom.ipagemysql.com', 'mantest', 'testman')

    or die(mysql_error());

mysql_select_db("learn2db",$link) or die(mysql_error());

You should also put quotes around the array index.

if (!isset($_GET['topic_id'])) {


If you are still not getting past that if() statement, then put this before the if statement for debugging purposes to see what, if any, values are present in the global $_GET array

echo "Get Vars:<pre>" . print_r($_GET) . "</pre>";
