This may help you. Add a check to make sure that your query is right, so if it is then it will run the code, else it will generate an error:
$query = "SELECT nickname FROM members WHERE fraction = 3";
if ($result = $mysqli->query($query))
{
if ($result->num_rows > 0)
{
while($row = $result->fetch_assoc())
{
echo "<p class='monitoring-name'>" . $row['nickname'] . "</p><br>";
}
}
else
{
echo "No results found"; // pretty clear?
}
}
else
{
// if there's an error with your query it will display this message:
echo "There was a problem with your query";
}
