mysql_fetch_array() returns 'supplied argument is not a valid MySQL result resource'

Question

I am trying the following code:

Answer 1

Your MySQL query possibly does not match any rows in the database.

Check the return value of mysql_query(), which returns "resource" on success and "false" on failure.

$query = "SELECT * FROM Auctions"; 
$result = mysql_query($query);

if ($result !== false) {
    while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { 
        foreach ($row as $field=>$value) { 
            echo $field . ':' . $value
        }
    }
} else {
    // query returned 0 rows
}

As others also suggested, you can use mysql_error() to look if the query returns any mySQL errors
