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）);}
{loop $da $d}

//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>
Related articles
{pc:content action="relation" relation="$relation" catid="$catid" num="5" keywords="$rs[keywords]"}
{loop $data $r}
Calling multiple pictures
{loop string2array($r['pics']) $v}
Calling ads
{php $banner=getads(11);$i=1;}
Calling friendly links
图片链接：
{pc:link action="lists" typeid="0" siteid="$siteid" linktype="1" order="desc" num="6" return="dat"}
{loop $dat $v}
<a></a>
{/loop}
{/pc}
文字链接：
{pc:link action="lists" typeid="0" siteid="$siteid" linktype="0" order="desc" num="10" return="dat"}
{loop $dat $v}
<a>{$v[name]} </a>
{/loop}
{/pc}
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);
Mysql search how to determine whether a field contains a certain string
利用mysql 字符串函数 find_in_set();
SELECT * FROM users WHERE find_in_set('aa@email.com', emails);
Calling the model drop-down box
{php $ks=filtersele('dertment',12);}
Path jump (without a tag):
<script>
function urls(obj){
var url = $(obj).attr('data-url');
window.location.href = url;
}
</script>
<span>返回</span>
Jump to the home page
{siteurl($siteid)}
Column picture call
{$CATEGORYS[$catid][image]}
Mobile site previous articleNext article
PHP源码修改：
打开 phpcms\modules\wap\index.php 文件
找到
if(!$r || $r['status'] != 99) showmessage(L('info_does_not_exists'),'blank');
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");
//当前页为第一篇时：再点击上一篇仍然显示第一篇
if(empty($previous_page)) {
$previous_page = $this->db->get_one("`catid` = '$catid' AND `id`='$id' AND `status`=99",'*','id DESC');
}
//当前页为最后一篇时：再点击下一篇仍然显示最后一篇
if(empty($next_page)) {
$next_page = $this->db->get_one("`catid`= '$catid' AND `id`='$id' AND `status`=99");
}
调用：
<a>上一条：{$previous_page[title]}</a>
<a>下一条： {$next_page[title]}</a>
