我使用的方法是jquery Ajax

$.ajax({
        url: 'http://localhost/myfolder/attendence_submit.php',
        data: $('#mySpan4').serialize(), 
        success: function(data) {


            tosmsphpdate ();
        }
    });

我的 PHP

$servername = "localhost";
$username = "root";
$password = "0000";

$dbname = "s_cool_age";
$conn = new mysqli($servername, $username, $password, $dbname);
// ** insert data in to data base ** //
$sql = "INSERT INTO attendance_master (StudentFirstName,AttendanceStatus,StudentRegID,SchoolID,Section,Standard,Subjects,AttendanceDate,UserType,Attendence_taken_by,Attendence_taken_date) VALUES ";
// **hear the data or is calculated using student as a string the number of student names are passed the same number of data is inserted in to data base ** //
foreach($_GET['student']  as $i=>$student) {

    // ** so the data is inserted in to data base   ** //
    $sql .= sprintf("%s ('%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s')"
    , ($i==0 ? '' : ',')  
    // **  data from Ajax   ** //
    , mysqli_real_escape_string($conn, trim($_GET['student'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['present'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['Reg'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['schoolid'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['section'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['standard'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['Subject'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['date1'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['UserType'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['Userid'][$i]))
    , mysqli_real_escape_string($conn, trim($_GET['date_user_submitted'][$i]))

    );
}
// ** on success full function   ** //
if ($conn->query($sql)) {
    // **can do any thing to recognise if the data is inserted if this gives the out put then the data is shorly inserted in to data base  ** //
}

【问题讨论】：

不同浏览器对查询字符串长度有不同的限制..
如何检查并作为移动应用执行此操作
为什么要在查询字符串中传递数据？？...查询字符串应尽可能小而简单。这将对您有所帮助boutell.com/newfaq/misc/urllength.html
使用哪种方法来传递请求？我建议使用 post 方法
ajax `$.ajax({ url: 'localhost/myfolder/attendence_submit.php', data: $('#mySpan4').serialize(), 成功: function(data) { tosmsphpdate (); } } );`

标签： javascript php ajax iis

【解决方案1】：

这肯定是 post 请求，而不是 get 请求。
普通表单处理和 ajax 的 GET/POST 选择是一样的。

应该使用GET：仅从服务器读取数据。 SQL 查询是“SELECT”查询。

POST 是更改服务器上的数据。 INSERT、UPDATE、DELETE 数据应始终使用 POST 完成

注意：URL 的长度是有限制的。这就是给你错误的原因。所以只使用 POST 应该可以解决问题。（但即使仅靠这个不能解决问题，还是照做）

这行得通。我跳过了数据库部分，因为我没有那个表。但我认为它应该有效。

我的 Ajax 返回是 echo $sql;

你可以使用更有趣的东西。

喜欢

<?php
if ($conn->query($sql)) {
  echo 1;
}
else  {
  echo 0;
}
?>

然后你可以在javascript的进一步处理中使用那个1/0（使用'success'/'error'）。

喜欢

success: function(data) {
  if(data == 1) {
    // success!
    // empty the form
    $('#myform').find("input[type=text], textarea").val("");  
    //  ...      
  }
}

没问题。顺便说一句，使用你看到的最新代码。我更新了我的答案几次
您好，需要您的帮助，帖子工作正常，但只插入了 97 行

【解决方案2】：

试试这个...

$.ajax({
            url: 'http://localhost/myfolder/attendence_submit.php',
            data: $('#mySpan4').serialize(),
            dataType: 'json' ,
            type: 'GET',
            success: function(data) {


                tosmsphpdate ();
            }
        });
