首先,我使用 PHP Dreamweaver 制作了一个带有 phpMyAdmin 数据库的程序。这个程序在我提交按钮时将我的第一行记录留空,并且一行中的剩余记录仍然存在,即第二行及以下,但第一行中的记录仍在数据库中,为什么会发生? 对我来说解决这个程序的任何想法,它也不会更新我的记录。这让我生病了,我需要帮助!:( tnx...

这是代码:

<?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());
  $row_Recordset1 = mysql_fetch_assoc($Recordset1);
  $totalRows_Recordset1 = mysql_num_rows($Recordset1);

  if(isset($_POST['submit'])) {
      $count = count($_POST['id']);
      $submit = $_GET['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;
    }   
 }
?>

你需要把:

$name = array_map('mysql_real_escape_string', $_POST['name']);
$lastname = array_map('mysql_real_escape_string', $_POST['lastname']);
$email = array_map('mysql_real_escape_string', $_POST['email']);
$id = array_map('mysql_real_escape_string', $_POST['id']);

在你的for循环之前。您正在使用这些变量,但从未从表单输入中填写它们。
