I have a pretty basic forum template I am working on for testing purposes
When I create a topic, and press submit, the proccess updates the database but doesn't output on the screen. Why is this? and Why am I getting a Resource id #4 when I echo the $result from this code below:
<?php
$host="server"; // Host name
$username="usernamehere"; // Mysql username
$password=""; // Mysql password
$db_name="forum"; // Database name
$tbl_name="question"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$sql="SELECT * FROM $tbl_name ORDER BY id DESC";
// OREDER BY id DESC is order result by descending
$result=mysql_query($sql);
echo $result;
?>

<table width="90%" border="0" align="center" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<td width="6%" align="center" bgcolor="#E6E6E6"><strong>#</strong></td>
<td width="53%" align="center" bgcolor="#E6E6E6"><strong>Topic</strong></td>

<td width="13%" align="center" bgcolor="#E6E6E6"><strong>Replies</strong></td>
<td width="13%" align="center" bgcolor="#E6E6E6"><strong>Date/Time</strong></td>
</tr>
<?php
// Start looping table row
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td>
<td bgcolor="#FFFFFF"><a href="view_topic.php?id=<? echo $rows['id']; ?>"><? echo $rows['topic']; ?></a><BR></td>
<td align="center" bgcolor="#FFFFFF"><? echo $rows['view']; ?></td>
<td align="center" bgcolor="#FFFFFF"><? echo $rows['reply']; ?></td>
<td align="center" bgcolor="#FFFFFF"><? echo $rows['datetime']; ?></td>
</tr>
<?php
// Exit looping and close connection
}
mysql_close();
?>
<tr>
<td colspan="5" align="right" bgcolor="#E6E6E6"><a href="create_topic.php"><strong>Create New Topic</strong> </a></td>
</tr>
</table>

You are getting resource id #4 because $result is an resource,you must extract the values contained in it by this way,
$result=mysql_query($sql);
$values = mysql_fetch_array($result);
var_dump($values);
More about resource variable
Update 2(From OP comments)
You are printing values using field name,In that case you will have to change to
while($rows=mysql_fetch_array($result,MYSQL_ASSOC))
Or you can directly use mysql_fetch_assoc(),which in your case will be
while($rows=mysql_fetch_assoc($result)){
echo $rows['id'];
}
