Question

i fetch two table result in one query. now i have in each table one row with name = userid. when i print id of table one, this not worked and printed id of table two . in i.e i select * from product and then voteid,userid form voteproduct where userid = $userid ; now i need print userid from product table but my result print userid from voteproduct . how to fix this ? thanks

my code :

$sql = 'SELECT * FROM ' . PREFIX  . '_product,' . PREFIX  . '_voteproduct WHERE ' . PREFIX  . '_voteproduct.voteid = ' . PREFIX  . '_product.id AND ' . PREFIX  . '_voteproduct.userid =  "' . $userid . '" ORDER BY name ' . $pages->limit .' ';

    $db->query($sql) or error ('ERROR', mysql_error ());
          $result = $db->query ( $sql ); 
          if($db->numrows($result)>0){ 
          while ($row = $db->fetcharray($result))
       {

    echo $row['userid']; // PROBELM THIS PRINTED USERID FROM VOTEPRODUCT I NEED PRINT USER ID FROM PRODUCT
       }

EDIT : If I selected * from my product table, realy i need to all. ( name, price, date, category, …)

You can select each userid with AS in order to use them separately like below

$sql = 'SELECT p.userid as pid, vp.userid as vpid, ... FROM ' . PREFIX  . '_product AS p,' . PREFIX  . '_voteproduct AS vp WHERE vp.voteid = p.id AND vp.userid =  "' . $userid . '" ORDER BY name ' . $pages->limit .' ';

And use ;

echo $row['pid'];
