php - 如何仅显示请求 ID？

Question

我想请教这里的前辈。我可以只显示 1 个 ID 吗？

当我单击第一行的查看时。我只想显示第一行。

+----+--------------+-------------+----------+---------+-----------------+---------------+-----------+---------------------+-----------+---------------+--------+------+--------+
| Id | username     | Peralatan   | Kuantiti | Tujuan  | Tarikh Pinjaman | Tarikh Pulang | Masa Guna |  Masa Terima        | Keputusan | KuantitiLulus | Respon | View | Delete |

+----+--------------+-------------+----------+---------+-----------------+---------------+-----------+---------------------+-----------+---------------+--------+------+--------+

但是，在我首先单击查看后，我得到了这个。

-----------------------------------------------------------

Tarikh Pinjam: 10/03/2013

这是我在上面显示数据的编码

$id =$_REQUEST['Id'];

            $query = "SELECT * FROM pinjaman ";

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

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

              {

              $id = $row['Id'];
              echo "----------------------------------------------------------- " ."<br/>";
              echo " Username: " . $row['username'] ."<br/>";
              echo " Peralatan: " . $row['BarangPinjaman']."<br/>" ;
              echo " Kuantiti: " . $row['Kuantiti']."<br/>" ;                 
              echo " Tarikh Pinjam: " . $row['tarikhpinjam'] ."<br/>";
              echo " Tarikh Pulang: " . $row['tarikhpulang']."<br/>";
              echo " Masa untuk di ambil: " . $row['masaguna']."<br/>";
              echo "----------------------------------------------------------- " ."<br/>";
              echo " Kepututsan: " . $row['keputusan']."<br/>";
              echo " Kuantiti yang di luluskan: ". $row['kuantitilulus']."<br/>";
              echo "----------------------------------------------------------- " ."<br/>";


              echo "</tr>";

              }

有什么建议吗？

更改您的查询以包含用户 ID

"SELECT * FROM pinjaman where id = ".intval(mysql_real_escape_string($id));
