随着虚拟化，Redis,BDB内存数据库等应用的普及，现在越来越多的服务器配置了大容量内存，拿DELL的R620来说在配置双路CPU下，其24个内存插槽，支持的内存高达960GB。对于ECC,REG这些带有纠错功能的内存故障检测是一件很头疼的事情，出现故障，还是可以连续运行几个月甚至几年，但如果运气不好，随时都会挂掉，好在linux中提供了一个edac-utils 内存纠错诊断工具，可以用来检查服务器内存潜在的故障。
下面以CentOS为例，介绍下edac-utils 工具的使用.
在使用edac-utils 工具之前，需要先了解服务器的硬件架构，以DELL R620为例，(其它如HP DL360P G8，IBM X3650 M4 机型都使用了 E5-2600 系列CPU，C600 系列芯片组.大致相同)  其CPU内存控制器对应通道，内存槽关系，如下所示。

处理器0 (对应一个内存控制器)
通道0：内存插槽A1、A5 和A9
通道1：内存插槽A2、A6 和A10
通道2：内存插槽A3、A7 和A11
通道3：内存插槽A4、A8 和A12

处理器1 (对应一个内存控制器)
通道0：内存插槽B1、B5 和B9
通道1：内存插槽B2、B6 和B10
通道2：内存插槽B3、B7 和B11
通道3：内存插槽B4、B8 和B12

1.安装 edac-utils 工具

yum install -y libsysfs edac-utils
2.执行检测命令，可查看纠错提示如下

> edac-util -v

其中 mc0 表示 表示内存控制器0,  CPU_Src_ID#0表示源CPU0 , Channel#0 表示通道0
DIMM#0 标示内存槽0，Corrected Errors 代表已经纠错的次数，根据前面列出的CPU通
道和内存槽对应关系即可给edac-utils 返回的信息进行编号。
即可得出 A1槽 6312 次纠错，B1槽 6459次纠错，B3槽 535次纠错. 3条内存出现潜在故障，接下来联系供应商进行更换即可。

使用方法：

覆盖到\phpcms\libs\functions这个目录下

后台添加字段（类型只能是联动菜单，和下拉列表）、然后选择作为筛选字段。

模板使用
===============================
 您已选择:
 {loop get_parent_url($modelid,'diqu') $r}
 <a href="{$r['url']}">{$r['name']}</a>
 {/loop}

==============================
联动菜单使用：

{php $zones = show_linkage(1,0,$modelid,'diqu')}
 {if !empty($zones)}
 <dl class="clearfix">
 <dt>地区：</dt>
 <dd class="more">全部展开</dd>
 <dd class="item_list">
 {loop $zones $r}
 {$r['menu']}
 {/loop}
 </dd>
 </dl>
 {/if}

或
{php $zones = show_linkage(3360,0,3,'bzfl', array('catid'=>9))}
                    {if !empty($zones)}
                                    {loop $zones $r}
                                {$r['menu']}
                            {/loop}
                    {/if}        
==========================
下拉列表使用

{loop filters('xz',$modelid) $r}
                {$r[menu]}
        {/loop}
==========================
配合列表标签使用：

{php $sql = structure_filters_sql($modelid);}
        {pc:content action="lists" where="$sql" catid="$catid" modelid="$modelid" num="10" page="$page"}

伪静态：
.ht  : RewriteRule ^.*list-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)\.html$ /index.php?m=content&c=index&a=lists&catid=$1&bzcolor=$2&bzfl=$3&pbsize=$4&pcsize=$5&sjsize=$6&page=$7

.is : <rule name="rD">
 <match url="^.*list-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)\.html$" />
 <action type="Rewrite" url="/index.php?m=content&c=index&a=lists&catid={R:1}&bzcolor={R:2}&bzfl={R:3}&pbsize={R:4}&pcsize={R:5}&sjsize={R:6}&page={R:7}" />
 </rule>

PHPCMS v9最实用的23个调用代码

作者: cokll 时间: 2014-10-16 评论: 暂无评论

今天给大家分享的是phpcms的一些最实用的调用代码。这也是我用phpcms以来觉得，这一套几乎能够解决到我很多问题，喜欢就做个评论，或者直接转走吧！
1、调用最新文章，带所在版块；
{pc:get sql="SELECT a.title, a.catid, b.catid, b.catname, a.url as turl ,b.url as curl,a.id FROM `v9_news` a, `v9_category` b WHERE a.catid = b.catid ORDER BY `a`.`id` DESC "num="15" cache="300"}
{loop $data $r}
[{$r[catname]}] {str_cut($r['title'],26)}
{/loop}
{/pc}
2、截取调用标题长度；
{str_cut($v['title'],34)} －－－－－超出用 ... 代替
{str_cut($v['title'],34, '???')}－－－－－超出用 ???代替
{str_cut($v['title'],34,'')}－－－－－超出不用任何字符代替
3、格式化时间调用；
{date('Y-m-d H:i:s',$r[inputtime])}－－－－－2013-07-25：11:22:33
{date('m-d',$v['inputtime'])}－－－－－－07-25
4、多栏目调用&多推荐位调用调用需求：文章范围为59 60 61三个栏目，并且推送到了27 和28两个推荐位；从第三条开始，连续调用7篇文章。
{pc:get sql="SELECT * FROM v9_news WHERE id IN (SELECT id FROM v9_position_data WHERE posidin(27,28) and catid in(59,60,61)) order by listorder DESC" cache="3600" start="3" num="7"return="data" }
{loop $data $n $r}
·{str_cut($r[title],22,'')}
{/loop}
{/pc}
5、显示栏目名称；
{$catname}－－－－－只显示名称不带链接
{$CATEGORYS[$r['catid']]['catname']}－－－－－显示栏目名称和链接
6、获取父栏目id/获取父栏目名称；
{$CATEGORY[$catid][parentid]}－－－－－父栏目ID
{$CATEGORYS[$CAT[parentid]][catname]}－－－－－父栏目名称
7、外部数据源调用dedecmsdb 在后台数据源处添加；
{pc:get sql="SELECT * FROM cq_member where mtype='企业' " cache="3600" dbsource="dedecmsdb"num="7" return="data"}
{loop $data $r}
{str_cut($r[uname],28,'')}
{/loop}
{/pc}
8、调用子栏目（在栏目首页模板需要用到）；
{pc:content action="category" catid="$catid" num="25" siteid="$siteid" order="listorderASC"}
{loop $data $r}
{$r[catname]} |{/loop}
{/pc}
9、显示指定id的栏目名称；
{$CATEGORYS[22]['catname']}
10、在文章面前显示文章类别；
{pc:content action="lists" catid="79" order="listorder DESC" num="14" }
{loop $data $n $r}
{if $TYPE[$r[typeid]][name]}[ {$TYPE[$r[typeid]][name]}]
{/if}{str_cut($r[title],33,'')}
{/loop}
{/pc}
11、指定变量循环增长（幻灯片经常用到）；
{pc:content action="lists" catid="66" order="listorder DESC" thumb="1" num="5" }
{php $num = 0}
{loop $data $r}
linkarr[{$num}] = "{$r[url]}";picarr[{$num}] = "{$r[thumb]}";textarr[{$num}] = "{str_cut($r[title],36,'')}";
{php $num++}
{/loop}
{/pc}
12、文章调用使用limit；
{pc:content action="position" posid="31" order="listorder DESC"  limit='1,8--'}
{loop $data $r}
{str_cut($r[title],36,'')}
{/loop}
{/pc}
13、文章从指定位置开始调用起始位置为5，调用3条；
{pc:content action="position" posid="27" order="listorder DESC" num="3" start="5"}
{loop $data $r}
{str_cut($r[description],115)}...
{/loop}
{/pc}
[page]
14、文章列表页调用关键字，或者首页调用关键字注意：explode(‘,’,$r[keywords]);是将文章关键词通过英文逗号分离，也就是说每一篇文章都要以逗号间隔关键字，否则调用出来会 是全部作为一个关键字。如果是空格间隔关键字，将explode(‘,’,$r[keywords]);改成explode(‘ ‘,$r[keywords]);
{pc:content action="lists" catid="$catid" num="10" order="id DESC" page="$page"}
{loop $data $r}
{$r[title]}
{php $keywords = explode(',',$r[keywords]);}
文章标签:
{loop $keywords $keyword}
{$keyword}
{/loop}
{/pc}
15、每当列表几行的时候出现一次某些符号(比如首页里面的文章推荐，一行显示两条，在这两条中间想加一条竖线 | 就用到这个代码了)数量大的话就容易出错，因为模运算嘛~~呵呵 不过一般也就4个标题以下；
{pc:content action="position" posid="8" order="listorder DESC" num="2"}
{loop $data $r}
{str_cut($r[title],26,'')}{if $n%2==1} |{/if}
{/loop}
{/pc}
16、v9 列表页完美支持自定义段调用；
{pc:content action="lists" catid="$catid" num="25" order="id DESC" page="$page"moreinfo="1"}
{loop $data $r}
[{$r['字段名']}]> {$r[title]}
{/loop}
{$pages}
{/pc}
[page]
17、当前栏目调用父级及以下栏目信息方法其他代码；
{php $arrchildid = $CATEGORYS[$CAT[parentid]][arrchildid]}
{pc:get sql="SELECT * FROM v9_news where catid in($arrchildid) cache="3600" page="$page"num="12" return="data"}
18、V9表单功能 提交之后如何返回当前页面，而不是默认的首页文件地址；
找到 phpcms\modules\formguide\index.php文件第73行

showmessage(L('thanks'), APP_PATH);

修改成 如下代码即可实现自动返回前一页

showmessage(L('thanks'), HTTP_REFERER);
19、v9 首页或分页自定义字段调用和15差不多第一普通列表或栏目调用自定义字段在{pc:content action=”lists” 后加上副表moreinfo=1 (等于1时显示，0时不显示)例子：
{pc:content action="lists" moreinfo=1 catid="2" order="id DESC" num="4"}
{loop $data $key $val}
{$val['title']}
价格：{str_cut($v['自定义段'],100)} //100 是字数
{/loop}
{/pc}
20、第二种推荐位调用自定义字段在模型里加好自定义字段后，必须把“在推荐位标签中调用”点击“是“然后用同一样的方法去调节数据就OK了，记住，如果你加了文章，必须去更新文章才会显示，自定义段在推荐中只显示你选择后，选择前加的加文章不显示，更新一下文章就显示了例子：
{pc:content action="position" posid="推荐位id" num="30" thumb="1" moreinfo="1"order="listorder DESC"}
{loop $data $key $val}
{str_cut($val['title'],20)}
{/loop}
{/pc}
21、编辑器上传图片自动使用标题作为alt参数；
一： 修改 statics/js/ckeditor/plugins/image/dialogs/image.js找到accessKey:'T','default':''
替换成accessKey:'T','default'('#title').val()
