Phpcms grouping

array_chunk($data（数组）,10（每组有几个数）)

<p>
    {pc:content action="lists" moreinfo="1" catid="17" num="20" order="id ASC"}
    {php $da=array_chunk($data,4（每组显示几个）);}

//Intercept the number of words

{str_cut($r[description],102,'...')} 

{str_cut(strip_tags($r[content]),300,"...")}  //截取文字  strip_tags() 函数剥去字符串中的 HTML、XML 以及 PHP 的标签。

Add to favorites and set the homepage

<a>加入收藏</a>
<a>设为首页</a>

Add anchor

{$r[url]}#n{$r[id]}  {$rs[url]}area{$n}

Time difference

{php $now = strtotime("now")}
{date('d',$now-$r[inputtime])}天前

Get the current column

{php $arrid=$r[catid]}   {$CATEGORYS[$arrid][catname]}

Get the parent column of the current column

{$CATEGORYS[$CATEGORYS[$arrid][parentid]][catname]}

Current position call:

{catpos($catid)}

phpcms starts calling from the specified number

{pc:content action="lists" catid="10" order="id DESC LIMIT 1,4--" num="4"}
//这样就可以从第二条开始调用数据。



其中的order="id DESC LIMIT 1,4--"里的两个数字，第1个数字1表示从第2条开始调用，第2个数字4表示共调用4条。

如果改成order="id DESC LIMIT 0,4--"那么就表示从第1条开始调用，共调用4条。

如果改成order="id DESC LIMIT 2,4--"那么就表示从第3条开始调用，共调用4条。


栏目指定第几个显示（phpcms从指定第几条开始调用 ）
1--->      从第二个开始显示
{php $data = array_slice($data,1);}


     {pc:content action="category" catid="$catid" num="5" siteid="$siteid" order="listorder ASC,id ASC"}
    {php $data = array_slice($data,1);}
        {loop $data $r}
             {if $cat==$catid}
            <span>{$r[catname]}</span>
             {else}
            <span>{$r[catname]}</span>                        {/if}
             {/loop}
        {/pc}

Return to the previous level

{$CATEGORYS[$catid][url]}
<a>返回上一级</a>

Calling friendly links

图片链接：
{pc:link action="lists" typeid="0" siteid="$siteid" linktype="1" order="desc" num="6" return="dat"}

Judge whether the array contains a certain number

if(in_array("29",$xmlx)){
    //array_push($xmlx,$qt);
    $qt=$_POST['qita'];
}

Column page calling source:

{php list($copyfrom) = explode('|', $r['copyfrom'])}  {$copyfrom}

Call verification code:

前台
{php pc_base::load_sys_class('form', '', 0);$setting = getcache('formguide', 'commons');} 
{form::checkcode('code_img', '4', 90, 30)}
 {form::checkcode('code_img','4','14',110,30)}
后台开始session配置
//启动session
$session_storage = 'session_'.pc_base::load_config('system','session_storage');
pc_base::load_sys_class($session_storage);

在其下面添加
//上一篇
$previous_page = $this->db->get_one("`catid` = '$catid' AND `id`db->get_one("`catid`= '$catid' AND `id`>'$id' AND `status`=99");
