PHP mysqli_fetch_array() OOP style

I want to run a SELECT query and fetch data as associative array and echo the fetched data. In procedural style I would use mysqli_fetch_array(). But I am now trying OOP style.

I have tried this code:

$con=  new mysqli('localhost','root','','afiliate');
$query="SELECT * FROM product WHERE ID=? ";
$stmt->bind_param("i",$ID); /* $ID has a value, it's ok */
$stmt->execute();
$result=$con->query($query);
while($row=$result->fetch_row()){
    echo $row['name'];
}

And the error I get is:

Fatal error: Call to a member function fetch_row() on boolean in /opt/lampp/htdocs/afiliate/product_details_individual.php on line 18

How can I fetch data and echo them?

You're doing two conflicting things

$con=  new mysqli('localhost','root','','afiliate');
$query="SELECT * FROM product WHERE ID=? ";
$stmt->bind_param("i",$ID); /* $ID has a value, it's ok */
$stmt->execute();

So at this point $stmt is a mysql_stmt object. If you have mysqlnd installed you can do this

$result = $stmt->get_result();
while($row=$result->fetch_row()){
    echo $row['name'];
}

This line can't work in this code block

$result=$con->query($query);

The SQL you are passing is for a prepared statement and cannot be executed directly using query(). Your query will fail (returns false when there is an execution error) and, as a result, you get the error you mentioned
