我m buissy for two day想知道我能对这个问题做些什么
第一页加载正常 我的问题如何获得加载其他页面$id？
第一个页面加载时 ？id=1 但在下一页上我收到一个错误
注意：未定义的索引：id in C： \ xampp \ htdocs \ 注释 \ 用户 \ 2 \ ajax.php 在第 5 行
这是我的阿贾克斯.php
<?php
include('../connection.php');
$id = (int) $_GET['id'];
$sql=mysqli_query($conn,"SELECT * FROM `user` WHERE id='" . $id . "' ");
$users=mysqli_fetch_assoc($sql);
?>
<?php
// Simulate slow server just to see loading indicator
sleep(2);
$type = isset($_GET['type']) ? $_GET['type'] : 'images';
switch ($type)
{
case 'data':
foreach (range(0,2) as $i)
{
?>
<div class="row-item">
</div>
<?php
}
break;
case 'images':
default:
$arr = array();
$dir = '../../images/'. $users['email'] .'/';
if ($handle = opendir($dir))
{
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != "..")
{
$arr[] = $dir.$entry;
}
}
closedir($handle);
}
$cnt = count($arr);
$items = array();
foreach (range(1,9) as $i)
{
$items[] = $arr[rand(0, $cnt-1)];
}
foreach (range(0,2) as $i)
{
?>
<div class="row-item">
<img src="<?php echo $items[3*$i]; ?>" class="img-responsive" alt="" />
<img src="<?php echo $items[3*$i+1]; ?>" class="img-responsive" alt="" />
<img src="<?php echo $items[3*$i+2]; ?>" class="img-responsive" alt="" />
</div>

在您的代码中，您使用的是没有任何参数的无限滚动。
<script> $(function () { $(document).pjInfiniteScroll(); }); </script>
把它改成这样。设置url
<script>
$(function () {
$(".container").pjInfiniteScroll({
// set the id here in the url
url: 'ajax.php?id=1'
});
});
</script>
