这个程序现在允许我连续更新记录，有人可以解决这个问题吗？

这是代码：我为此使用 Dreamweaver

PHP 代码：需要更多答案

<?php require_once('Connections/tlsc_conn.php');
 mysql_select_db($database_tlsc_conn, $tlsc_conn);
  $query_Recordset1 = "SELECT * FROM tbl_name";
 $Recordset1 = mysql_query($query_Recordset1, $tlsc_conn) or die(mysql_error());

  $totalRows_Recordset1 = mysql_num_rows($Recordset1);


 if(isset($_POST['submit'])) {

//    $count = count($_POST['id']);
//  $count=mysql_num_rows($Recordset1);
    $submit = $_GET['submit'];
$i = ($_POST['count']);
$name = ($_POST['name']);
$lastname = ($_POST['lastname']);
$email = ($_POST['email']);
$id = ($_POST['id']);

    for($i=0;$i<$count;$i++){

        $sql1="UPDATE $tbl_name SET name='$name[$i]', lastname='$lastname[$i]', email='$email[$i]' WHERE id='$id[$i]'";

        $row_Recordset1=mysql_query($sql1);
    }

    if($row_Recordset1){
            header("location:lulu.php");
            exit;
    }   
 }


?>

HTML 代码：我不认为它是否已修复，但我认为它是...

    <tr>
      <td><?php $id[]=$row_Recordset1['id']; ?><?php echo $row_Recordset1['id']; ?>

$sql1="UPDATE $tbl_name

没有名为 的变量$tbl_name，因此您的查询失败：它不知道要更新哪个表，这是语法错误。

上面的代码中没有带有 $tbl_name 的变量。正确使用这个变量，它就会起作用。

<?php
$i = ($_POST['count']);
$name = ($_POST['name']);
$lastname = ($_POST['lastname']);
$email = ($_POST['email']);
$id = ($_POST['id']);
$tbl_name = ???

$sql1="UPDATE $tbl_name SET name='$name[$i]', lastname='$lastname[$i]', email='$email[$i]' WHERE id='$id[$i]'";

?>
