Question

每日问候!!!

我在使用ajax URL传递参数时遇到问题。我正在尝试使用jquery $ .ajax方法将多个数据发送到我的php脚本，但是当我连接多个数据时，我只能传递单个数据。当我尝试更新另一个字段但该字段未更新并且第一个更新时。只有第一次现场更新。遗留字段不更新。我正面临更新其他字段的问题。我也尝试在ajax URL中传递多个参数但是收到错误。不更新任何字段。
请检查我的代码并给我解决方案。

我希望你们都明白。

谢谢!!!

这是我的代码：

include("connect.php");

这是我的另一个档案：

<?php
include("connect.php");
if($_GET['id'])
{
    $id = $_GET['id'];
    $fname = $_GET['fname'];
    $lname=$_GET['lname'];
    $email=$_GET['email'];

    $gender=$_GET['gender'];
    $address=$_GET['address'];
    $city=$_GET['city'];
    $course=$_GET['course'];
    $hobby = explode(',', $_GET['hobby']);
    if(mysql_query("UPDATE student_data SET fname='$fname', lname = '$lname', email = '$email', gender='$gender', address='$address', city='$city', course='$course', hobby='$hobby' where id='$id'"));
    echo 'success';
}
?>

这里是Ajax代码：

<script type="text/javascript">
    jQuery(document).ready(function() {  
        $.fn.editable.defaults.mode = 'popup';
        $('.xedit').editable();     
        $(document).on('click','.editable-submit',function(){
         var x = $(this).parents('td').children('span').attr('id');
         var y = $('.input-sm').val();
         var z = $(this).parents('td').children('span');
         alert(x);
         alert(y);
         alert(z);
         $.ajax({
            url:"process.php?id="+x+"&fname="+y,
            type: 'GET',
            success: function(s){
               if(s == 'city'){
                   $(z).html(y);}
                   if(s == 'error') {
                       alert('Error Processing your Request!');}
                   },
                   error: function(e){
                       alert('Error Processing your Request!!');
                   }
               });
     });
    });
</script>

Answer 1

问题在于：

csv

在这里，您只发送url:"process.php?id="+x+"&fname="+y,和id，并在PHP脚本中尝试获取：

fname

ans这么多参数，这是错误的。

发送多个参数的正确方法是：

$id = $_GET['id'];
$fname = $_GET['fname'];
$lname=$_GET['lname'];

或通过在其中附加所有data: { key1: value1, key2: value2, key3: value3, and so on }：key来格式化正确的网址，如：

value

Answer 2

发送单个参数

data: "id="+id,

发送多个参数

data: {
    id: id,
    fname: fname
},
