php+jQuery implements news tag classification and refresh-free paging_PHP tutorial

Nowadays, jquery is used more and more widely, and the effect of tag classification + non-refresh paging has been implemented in the news section of many websites.

I also tried to write one myself, and the rendering is as follows (the style can be customized according to user needs):

The implementation process will be introduced in detail below:

I have always tried to solve the problem by seeing the tricks. Three things need to be used here - tab effect plug-in and paging plug-in, and jquery's getJson request.

So I used the jquery-ui plug-in and jquery-page plug-in. Please click on the file name below to download.

It contains 3 JS script files and 2 style sheets:

jquery-1.3.2.min.js

jquery.pager.js

jquery-ui-1.7.2.custom.min.js

jquery-ui-1.7.2.custom.css

page.css

The html page code is as follows:

Copy to Clipboard引用的内容：[www.bkjia.com]

• 2009年


• 2008年


• 2007年

The page makes getJson requests for three pages: ajax4.php, ajax5.php, and ajax6.php.

The codes of these three pages are similar. They are just the classification of years. I have not done the code here. It has been optimized.

can actually be processed on the same page. Just add a parameter to the request address.

Ajax.php code is as follows:

Copy to ClipboardQuoted content: [www.bkjia.com]
header("content-type:text/html;charset:utf-8");
$db = @ mysql_connect("Server host address", "Database account"," Database password");
mysql_select_db("database name");
$rs=mysql_query("set names utf8");
//If the pager parameter is passed
if(isset($_GET ['pager']) && isset($_GET['count']))
{
echo GetPager($_GET['count'],$_GET['pager']);
}
else
{
echo "No parameters passed in!";
}


function GetPager($count,$pager)
{

$begin = start time;
$end = end time;

$rs=mysql_query("SELECT * FROM data table WHERE (pubdate BETWEEN $begin AND $end) ORDER BY pubdate DESC limit ". ($pager-1)*$count.",".$count);

while ($r=mysql_fetch_assoc($rs))
{
$temp[]=$r;
}

$html_string="";
foreach($temp as $k=>$v)
{
//Assume that the url field is the link address, title is the news title, and pubdate is the publication time

$html_string.=" ";
}


$html_string.="

".$v['title']. "

".$v["pubdate"]."

";
//This is the number of news reads, it is not recommended to read too much
$num=40 ;
//The total number of news pages is rounded
$num_string=ceil($num/$count);

//The data in JSON format is returned here in the form of key-value pairs, 0 is the total number of news pages, 1 is the spliced ​​HTML news page
$arr=array("0"=>$num_string, "1"=>$html_string);
$jarr=json_encode($arr );
echo $jarr;

}

?>
