Question

I’m having trouble getting any information to display from this query. Anyone know where I’m going wrong?

Thank you!

 $query =   "SELECT * ".
            "FROM comments, users ".
            "WHERE comments.user_id = users.user_id ".
            "ORDER BY comments.date DESC ".
            "LIMIT 10";

$result = mysql_query($query) or die(mysql_error());

   while ($row = mysql_fetch_array($result)) {


  echo $row['users.user_id'];
  echo $row['comments.comment'];


 }

You’re probably getting the error because you are sorting (ORDER BY) on a field that does not exist in your query.

It would be best practice to not use the “SELECT *” querying. If all you need are specific values, specify them. This also helps when retrieving the data…

$query =   "SELECT users.user_id, comments.comment, comments.date ".
                        "FROM comments, users ".
                        "WHERE comments.user_id = users.user_id ".
                        "ORDER BY comments.date DESC ".
                        "LIMIT 10";

$result = mysql_query($query) or die(mysql_error());

   while ($row = mysql_fetch_array($result)) {


  echo $row['user_id'];
  echo $row['comment'];
  echo $row['date'];
