通过php中的链接显示来自另一个表的数据

Question

我有2个数据库表1是用户表，其他是market_offer表。我想用户显示优惠。就像用户发送报价时只更新当前报价一样，所有报价必须在更多报价页面上，该页面应该只包含特定的用户数据。

这是一段代码：

//Market_offer.php where I have displayed offers according to users_id
<div class="panel panel-body">  
                        <?php 
                        $output = '';  
                        $query =    "SELECT u.*,t.* 
                                    FROM users u
                                    JOIN add_offer t ON t.user_id = u.id
                                    GROUP BY u.id, u.name ORDER BY t.id DESC";  
                        $res = mysqli_query($connect, $query);  
                        while($row = mysqli_fetch_array($res))  
                        {  
                            $output .= '<div class="col-md-3 col-sm-4 col-lg-6">';  
                            $output .= '<div class="panel panel-default">';  
                            $output .= '<div class="panel-heading">'.preg_replace("/(?!^)./", "*", $row["name"]).'</div>';
                            $output .= '<div class="panel-body">'; 
                            $output .= '<div style="padding:3px;float:left;font-weight:bold;">'.$row["part_no"].'</div>'; 
                            $output .= '<div style="padding:3px;float:left;">'.$row["make"].'</div>'; 
                            $output .= '<div style="padding:3px;float:left;">'.$row["date_code"].'</div>'; 
                            $output .= '<div style="padding:3px;float:left;">'.$row["qty"].'</div>';  
                            $output .= '<br>';  
                            $output .= '<div style="float:left;font-size:9px;">'; 
                            $output .= '<a href="user.php?id='.$row["user_id"].'">More Offers>>';           
                            $output .= '</a>';
                            $output .= '</div>';
                            $output .= '<div style="float:right;font-size:9px;">'.date('d-m-Y H:i:s',strtotime($row["time"])).'</div>';

                            $output .= '</div>';  
                        }  
                        echo $output;
                        ?>  
                    </div>
