Question

I have a script which prints out messages from within a database.

Each message is written by a different user.

What I would like is for only users who are friends with the message creator, be able to view the message.

The script I have is:

foreach($updatesarray as $data)
 {
 $qu=mysql_query("SELECT frid FROM friends WHERE usid='$uid'")or die(mysql_error());
 $dataq=array();
 $qurow=mysql_fetch_array($qu);
 $dataq[]=$qurow['frid'];
foreach($dataq as $value){
  if($value!=$data['uid_fk'])
    continue;
}

/ Continues the output of the message

The first foreach takes the data from the mysql query array.
Then within that foreach I perform another mysql query to identify the list of friends for the currently logged in user. I put the results into an array and create a new foreach. If any of the loops are found NOT to be a user, it will then continue… But it isn’t continuing how I would like it to. I need it to skip the whole output of the message, instead of continuing the second foreach.

The variable $data[‘uid_fk’] is the message creator stored in the database.

Database query:

if($viewtype=="friends"){
         $viewquery="M.uid_fk=U.uid";
         $query = mysql_query("SELECT M.msg_id, M.uid_fk, M.message, M.created,       U.username, U.firstname, U.middlename, U.surname, M.uploads FROM messages M, users U  WHERE     $viewquery $morequery order by M.msg_id desc limit " .$this->perpage) or     die(mysql_error());

        }

You have to join messages and friends tables in query, and in one shot you have both.
