嗨，这是我的php文件的一部分。

include_once 'dbconnect.php';
$query  = "SELECT * FROM promoter";
$result = mysql_query($query);
echo "<table border='"2'">'n"; 
echo "   <tr>'n"; 
echo "      <th>Id</th>'n"; 
echo "      <th>User Id</th>'n"; 
echo "      <th>Full Name</th>'n"; 
echo "      <th>Qualification</th>'n";
echo "      <th>Locality</th>'n";
echo "      <th>Description</th>'n";
echo "      <th>Language</th>'n";
echo "      <th>Bank Details</th>'n";
echo "      <th>Change</th>'n";

echo "    </tr>'n";
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{   
print "<tr> <td>";
    echo $row['id']; 
    print "</td> <td>";
    echo $row['user_id']; 
    print "</td> <td>";
    echo $row['full_name']; 
    print "</td> <td>";
    echo $row['qualification'];
    print "</td> <td>";
    echo $row['locality'];
    print "</td> <td>";
    echo $row['description'];
    print "</td> <td>";
    echo $row['language'];
    print "</td> <td>";
    echo $row['bank_details'];
    print "</td> <td>";
     //echo '<a href="update.php" >Modi</a>';
    echo '<a href="update.php" id= "<?php echo $row['id'];?>">Modify</a>';
    print "</td> </tr>";
}

echo " </table>'n";
include 'closedb.php';

我想在单击链接按钮时获得表行的行id。我怎么能拿到？表中的每一行都有一个链接，因此当单击链接时，它应该将行['id']作为id值，因此每个链接都有其行id的id值。

试试这个，

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{   
    print "<tr> <td>";
    echo $row['id']; 
    print "</td> <td>";
    echo $row['user_id']; 
    print "</td> <td>";
    echo $row['full_name']; 
    print "</td> <td>";
    echo $row['qualification'];
    print "</td> <td>";
    echo $row['locality'];
    print "</td> <td>";
    echo $row['description'];
    print "</td> <td>";
    echo $row['language'];
    print "</td> <td>";
    echo $row['bank_details'];
    print "</td> <td>";
     //echo '<a href="update.php" >Modi</a>';
    echo '<a href="update.php?id= "'.$row['id'].'">Modify</a>';
    print "</td> </tr>";
}

试试这个，

(in your php file)
echo '<a href="update.php" id= ".$row['id']." onclick="getId(this)">Modify</a>';
<script>
function getId(link){
    alert(link.id);
}
</script>

PHP可以使用多种类型的requests。两种最常见的请求是POST和GET请求。

GET请求是在您通常单击链接时对服务器执行的请求。

示例

<a href="index.php?id=1">Click me</a>
<?php if (isset($_GET['id'])): ?>
    The requested id is <?= $_GET['id']; ?>
<?php endif; ?>

在上面的示例中，我们请求具有GET参数id的index.php。PHP将这些参数存储在超全局CCD_ 8中。

在您的情况下：

while (...) {
    echo "<a href='modify.php?id='".$row['id']."'>Modify</a>";
}
