【中文标题】使用jquery sql插入多行并且php不起作用【英文标题】：Insert multiple rows using jquery sql and php is not working 【发布时间】：2021-04-16 22:06:34 【问题描述】：我正在使用以下脚本尝试将新行插入我的数据库。由于某种原因，只插入了第一行，就像没有发布其他行一样。我找不到问题所在，我没有收到错误日志，也看不到任何拼写错误或差异。
有人知道我做错了什么吗？
php 和 SQL：
if(isset($_POST['submitnewacc']))
for($i=0;$i<count($_POST['slno']);$i++)
$name = $_POST['name'][$i];
$email = $_POST['accmail'][$i];
$password = $_POST['password'][$i];
$bullets = $_POST['bullets'][$i];
$notes = $_POST['notes'][$i];
$rang = $_POST['rang'][$i];
$betaald = $_POST['betaald'][$i];
$paydate = $_POST['paydate'][$i];
if ( trim($name) != '') $nameacc = trim($name);
if ( trim($email) != '') $emailacc = trim($email);
if ( trim($password) != '') $passwordacc = trim($password);
if($betaald =='') $betaald = 'No';
if($nameacc != '' && $emailacc != '' && $passwordacc != '' && $bullets >= '0')
$stmt16 = $mysqli->prepare("
INSERT INTO account (name,email,password,bullets,rang,betaald,testpay,door,group_name,notes)
VALUES (trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?))");
$stmt16->bind_param('ssssssssss',$nameacc,$emailacc,$passwordacc,$bullets,$rang,$betaald,$paydate,$usernamesession,$groupname,$notes);
$stmt16->execute();
$stmt16->close();
if($stmt16 == TRUE)
$log_page = "Newaccount";
$log_account = filter_var($name, FILTER_SANITIZE_STRING);
$datum = filter_var(date ("Y-m-d H:i:s"), FILTER_SANITIZE_STRING);
$message = filter_var($usernamesession." added a new account: ".$log_account." (rang: ".$rang.", bullets: ".$bullets.",
, paying: ".$betaald.", notes: ".$notes.")", FILTER_SANITIZE_STRING);
$userip = htmlspecialchars(filter_input(INPUT_SERVER, 'REMOTE_ADDR', FILTER_SANITIZE_STRING));
$stmt12 = $mysqli->prepare("INSERT INTO logs (user_ID, log_action, log_time, log_ip, log_account, log_page,
log_owner, log_group) VALUES (trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?),trim(?))");
$stmt12->bind_param('isssssss',$userid,$message,$datum,$userip,$log_account,$log_page,$usernamesession,$groupname);
$stmt12->execute();
$stmt12->close();
$_SESSION['addacc'] = '<p><b><font color="orange">You have succesfully added the accounts to the database!</p>

【问题讨论】：
" 就像其他行没有发布"...您需要再调试一下，可以肯定的是。使用浏览器的开发者工具查看实际发布的。并在你的 PHP 中添加一些日志以查看 $_POST 数据是什么样的，代码采用什么路径，实际执行了多少插入查询，是否有任何失败，等等。 只是为了清楚。我不是专业的开发人员。我是新手，正在尝试边做边学。我以检查控制台而闻名，但我不知道在哪里可以找到发布的内容。发布的行是脚本不适应创建更多行的行。 这些说明适用于 Chrome，但大多数其他浏览器的工具类似：加载您的表单。打开开发者工具。转到网络选项卡。确保勾选“保留日志”框。然后添加一些行，填写一些数据，然后提交表单。您应该会看到对 .php 脚本的 POST 请求。点击请求。在出现的信息的“标题”选项卡中，向右滚动到底部，您应该会看到“表单数据”部分。进去看看。 在 PHP 端，您可以使用var_dump($_POST); 使 PHP 输出它接收到的数据的视图（它应该与浏览器显示的数据相同已提交）。
谢谢。照你说的做了。两者都显示了我发布的实际帖子..现在该怎么办..
【参考方案1】：
这段代码：
header('Location: ' . 'lijst_myaccounts.php');
exit();
需要在您的for 循环结束后移至。否则它将在循环的第一次迭代期间退出脚本。
【讨论】：
我删除了 exit();。现在它起作用了！谢谢，没想到！ 不，不要删除它，这是一个错误。按照我的建议移动它。 像这样移动它。 ` else echo '错误提交数据'; header('位置：' . 'lijst_myaccounts.php');出口（）; ` 我明白了。是的，这就是我想要你做的。以上是关于使用jquery sql插入多行并且php不起作用的主要内容，如果未能解决你的问题，请参考以下文章
