Andre,
The @ operator is used for error catching statements. When you put:
@mysql_connect('localhost', 'username', 'password') or die('Could not
connect.');
If PHP fails to make a connection, the script execution is stopped, and the
error message between the apostrophes is given.
And, I found out what the problem was; I should have put:
if (mysql_num_rows($result))
rather than just
if ($result)
Thanks!

Hello Parham,
Adding to Ash's question, why to use the @ operator before
mysql_query?

Subject: MySQL query not working!
Hi there,
Here is a snippet of code... that doesn't work for some reason. Please
note
that I have put some
@mysql_query($query) or die(mysql_error());
statements, to see if MySQL gives an error. I receive nothing other than
the
file starting to download. This is supposed to be a file download counter:
[code]
<?php
//connect to the DB
mysql_connect() //There is no problem with the connection so I didn't
include the complete code.
//The table where the hits are stored.
$table = "files";
$query = "select * from " . $table . " where filename = '" . $_GET['file']
.
"'";
$result = mysql_query($query);
if ($result) //Has the file previously been added?
{
$query = "update " . $table . " set hits = hits + 1 where filename = '" .
$_GET['file'] . "'";
@mysql_query($query) or die(mysql_error());
header('location:http://www.qwitter-client.net/' . $_GET['file']);
}
else //it's the first time we're adding this file to the DB.
{
$query = "insert into " . $table . " (filename, hits) values ('" .
$_GET['file'] . "', 1)";
@mysql_query($query) or die(mysql_error());
header('location:http://www.qwitter-client.net/' . $_GET['file']);
}
?>
