3.016版本添加文章点击量功能

这个教程以及相关代码是在3.0.1.6版本基础上写的，如果后面的版本，可能有些代码或者路径写法不一样，需要自己参考相关文件代码修改。

此教程分两个部分，第一部分是教程，第二部分是相关文件的代码。

第一部分：

1、数据库jtbc_news添加n_count字段，类型INT，长度11

2、头部模板引入main.js文件

<script type="text/javascript" src="{$=$global.assetspath}/js/jquery-3.3.1.min.js"></script>
<script type="text/javascript" src="{$=$global.assetspath}/js/main.js"></script>
<script type="text/javascript" src="{$=$global.assetspath}/js/jtbc.js"></script>

3、news模块详情页模板修改

3.1底部添加js代码

<script type="text/javascript">
function innerCOUNT(strers)
{
if (strers != "$error$") get_id("count").innerHTML = strers;
};
igets("../universal/count/?type=action&action=count&genre={$>genre}&id={$id}", innerCOUNT);
</script>
{$=take('.public.footer')}

3.2需要显示点击量的位置添加标签
<span id="count">0</span>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

第二部分

1、增加universal/count/index.php文件，代码如下

<?php
header('content-type: text/html; charset=utf-8');
function p($p){return is_file($p)? $p: p('../' . $p);}
require_once(p('common/incfiles/jtbc.php'));
echo require_inc_and_get_result(__FILE__);
?>

2、增加universal/count/common/incfiles/index.inc.php文件，代码如下

<?php
namespace jtbc;
class ui extends page {
public static function moduleActionCount()
{
$id = base::getNum(request::getHTTPPara('id', 'get'), 0);
$genre = request::getHTTPPara('genre', 'get');
$db = self::db();
if (!is_null($db))
{
$table = tpl::take('global.' . $genre . ':config.db_table', 'cfg');
$prefix = tpl::take('global.' . $genre . ':config.db_prefix', 'cfg');
$sqlstr = "select " . $prefix . "count from " . $table . " where " . $prefix . "delete=0 and " . $prefix . "publish=1 and " . $prefix . "id=" . $id;
$rq = $db -> query($sqlstr);
$rs = $rq -> fetch();
if (is_array($rs))
{
$sqlstr = "update " . $table . " set " . $prefix . "count=" . $prefix . "count +1 where " . $prefix . "id=" . $id;
$rq = $db -> query($sqlstr);
echo $rs[0];
}
}
}
}
?>

3、增加common/assets/js/main.js文件，代码如下

var agt = navigator.userAgent.toLowerCase();
var isie = (agt.indexOf("msie")!= -1 && document.all);
var client_test;

if (document.getElementById)
{ client_test = "a"; }
else if (document.all)

var request = new function()
{
var iname,ivalue,icount;
var urlstr = location.href;
var inum = urlstr.indexOf("?")
urlstr = urlstr.substr(inum + 1);
var arrtmp = urlstr.split("&");
for(icount = 0; icount < arrtmp.length; icount++)
{
inum = arrtmp[icount].indexOf("=");
if(inum > 0)
