Question

我已经提到过这篇文章How to get row ID in button click?，但仍然无法使其加载值，我不知道为什么。我很确定id已经在profile.php中被正确捕获。以下是我的代码：

hanj.php

  style type="text/css">
      .buttonize {
        text-decoration: none;
        border: 1px solid #ccc;
        background-color: #efefef;
        padding: 10px 15px;
        -moz-border-radius: 11px;
        -webkit-border-radius: 11px;
        border-radius: 11px;
        text-shadow: 0 1px 0 #FFFFFF;
      }
     <?php require_once('Connections/conn.php');?>
    </style>
    <table border="1" cellpadding="5" cellspacing="2" width="600">
    <tr>
      <th>Vendor Id</th>
        <th>Kategori</th>
        <th>Nama Vendor</th>
        <th>Alamat</th>
        <th>Poskod</th>
        <th>Bandar</th>
         <th>Negeri</th>
         <th>No</th>
         <th>Email</th>
    </tr>



     <?php
     session_start();
     $_SESSION['profile']= $row ['v_id'];
    mysql_select_db ($database_conn,$conn);
    $query="SELECT v_id,type,companyName,address,code,city,state,contact,email FROM vendor";
    $result=mysql_query($query) or die(mysql_error());

    while($row=mysql_fetch_array($result))
    {
         echo "</td><td>";
        echo $row['v_id'];
        echo "</td><td>";
        echo $row['type'];
        echo "</td><td>";
        echo $row['companyName'];
        echo "</td><td>";
        echo $row['address'];
        echo "</td><td>";
        echo $row['code'];
        echo "</td><td>";
         echo $row['city'];
        echo "</td><td>";
         echo $row['state'];
        echo "</td><td>";
        echo $row['contact'];
        echo "</td><td>";
        echo $row['email'];
        echo "</td><td>";
        print '<center><a href="profile.php?id='.$row['v_id'].'" class="buttonize">View</a></center>';
        echo "</td></tr>";
    }
    ?>

                </div>
                </div>

    </body>
    </html>

btw没有语法错误

Answer 1

在profile.php中使用$ _GET来引用传入的'id'。即替换以下行

$vid = $_SESSION['profile'];

这个。

$vid = $_GET['id'];

希望这有帮助。

Answer 2

这个问题由Bikash Paul回答，他建议将$ _SESSION [＆＃39;个人资料＆＃39;]更改为$ _REQUEST [＆＃39; id＆＃39;]

Answer 3

而不是$vid = $_SESSION['profile'];尝试$vid = $_GET['profile'];，如果不起作用，则print_r（$ _ GET）或print_r（$ _ REQUEST）＆amp;向我们展示详细信息

Answer 4

而不是$_SESSION['profile']在您的$_REQUEST['id']中使用profile.php而应该有效。
