Question

$query="select * from messages where client_id='$client_id' ORDER BY `id` DESC";

the script above doesn’t seems to work, i want to select all data equal to the useer input while posting it in descending order

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

                                        while ($row = $result->fetch_object())
                                        {
                                                $mes_agent_id = $row->poster_id;
                                                $id = $row->msg_id;
                                                $mes = $row->message;
                                                $mes = nl2br($mes);
                                                $cdate = $row->date_post;
                                                $msg ="{$mes} <br> . {$cdate}";

                                                $query_agnt ="select * from agent_info where id='$mes_agent_id'";
                                                $result_agnt = $mysqli->query( $query_agnt );
                                                $row_agnt = $result_agnt->fetch_object();
                                                        $mes_agent_first = $row_agnt->first;
                                                        $mes_agent_last = $row_agnt->last;

Please change this statement :

$query="select * from messages where client_id='" . $client_id ."' ORDER BYidDESC";
