www.mysite.com/index.php?order_by=id asc

我想送$name和$_GET[order_by]到autoload_process.php，我该怎么办？

。

的index.php

<!DOCTYPE html>

<?php 
include("connect.php"); 
$items_per_group = 5; 
$mysqli = new mysqli($DB_HOST, $DB_USER, $DB_PASSWORD, $DB_NAME); 

$results = $mysqli->query("SELECT COUNT(*) as t_records FROM product_details"); 
$total_records = $results->fetch_object(); 
$total_groups = ceil($total_records->t_records/$items_per_group); 
$results->close(); 
?> 

<script type="text/javascript"> 
$(document).ready(function() { 
    var track_load = 0; //total loaded record group(s) 
    var loading = false; //to prevents multipal ajax loads 
    var total_groups = <?php echo $total_groups; ?>; //total record group(s) 

    $('#results').load("autoload_process.php", {'group_no':track_load}, function() {track_load++;}); //load first group 

    $(window).scroll(function() { //detect page scroll 

     if($(window).scrollTop() + $(window).height() == $(document).height()) //user scrolled to bottom of the page? 
     { 

      if(track_load <= total_groups && loading==false) //there's more data to load 
      { 
       loading = true; //prevent further ajax loading 
       $('.animation_image').show(); //show loading image 

       //load data from the server using a HTTP POST request 
       $.post('autoload_process.php',{'group_no': track_load}, function(data){ 

        $("#results").append(data); //append received data into the element 

        //hide loading image 
        $('.animation_image').hide(); //hide loading image once data is received 

        track_load++; //loaded group increment 
        loading = false; 

       }).fail(function(xhr, ajaxOptions, thrownError) { //any errors? 

        alert(thrownError); //alert with HTTP error 
        $('.animation_image').hide(); //hide loading image 
        loading = false; 

       }); 

      } 
     }

'$ name'未在'index.php'中声明或定义 – krishna

$ name is php available '$ name = session（Username ）' – user3282833

首先url参数值保存到一个隐藏的输入框，这样

<input type="hidden" id="orderby" value="<?php echo $_GET['orderby']; ?>"/>

和会话varaible像

<input type="hidden" id="name" value="<?php echo $_SESSION['Username']; ?>"/>

然后通过在$值。 POST这样

var orderby = $("#orderby").val(); 

var name = $("#name").val(); 

$.post('autoload_process.php',{'group_no': track_load, 'order_by':orderby, 'name':name} , function(data){

以及如何发送$ name到autoload_process.php – user3282833

使用相同的进程将其保存在单独的'input'框中，将值存储在jquery变量中并将其传递到'$ .POST'中 – krishna

的$ .POST第二个参数是 “数据”。您可以将您的变量作为对象发送。

例如：{ 'group_no': track_load, name: 'John Smith', order_by: 'id asc' }
