帝國(guó)CMS無(wú)限加載是借鑒別的CMS插件更改的?，F(xiàn)在還在制作樣式中，完成后會(huì)以插件分享給大家！

無(wú)限加載常見的原理是利用PHP文件調(diào)用數(shù)據(jù)庫(kù)信息，在用JS讀取PHP信息，最后插入顯示到頁(yè)面。

PHP文件代碼

<?php
require_once('../../e/class/connect.php'); //引入數(shù)據(jù)庫(kù)配置文件和公共函數(shù)文件
require('../../e/class/db_sql.php'); //引入數(shù)據(jù)庫(kù)操作文件
$link=db_connect(); //連接MYSQL
$empire=new mysqlquery(); //聲明數(shù)據(jù)庫(kù)操作類
$editor=1; //聲明目錄層次

$last = $_POST['last'];
$amount = $_POST['amount'];

$user = array('demo1','demo2','demo3','demo3','demo4');
$sql=$empire->query("select * from ceshi_ecms_news order by id desc limit $last,$amount");

while ($row=$empire->fetch($sql)) {
	$addurl="<a href=".$row['titleurl'].">".$row['title']."</a>";
	$sayList[] = array(
		'content'=>$row['username'],
		'author'=>$addurl,
		'url'=>$row['titleurl'],
		'date'=>date('m-d H:i',$row['newstime'])
      );
}
echo json_encode($sayList);

db_close(); //關(guān)閉MYSQL鏈接
$empire=null; //注消操作類變量
?>
