标签说明:灵动标签是无需做标签模板,且模板内容为PHP代码,因而更灵活,可以使用php所有处理函数。使用本标签,需开启模板支持程序代码(参数设置)。

参数:

  • 栏目ID/专题ID:查看栏目ID点这里,查看专题ID点这里,当前ID='selfinfo',多个栏目ID与专题ID可用,号格开,如'1,2'。
  • 显示条数:显示前几条记录。
  • 操作类型:具体看操作类型说明。
  • 只显示有标题图片:0为不限制,1为只显示有标题图片的信息。
  • 附加SQL条件:附加调用条件,如:"title='帝国'"。
  • 显示排序:可指定按相应的字段排序,如:"id desc"。

变量说明:

  • $bqr:$bqr[字段名]:显示字段的内容
  • $bqsr:$bqsr[titleurl]:标题链接,$bqsr[classname]:栏目名称,$bqsr[classurl]:栏目链接
  • $bqno:$bqno:为调用序号
  • $public_r:$public_r[newsurl]:网站地址

常用函数介绍:

文字截取:esub(字符串,截取长度),例子:esub($bqr[title],30)截取标题前30个字符。

时间格式:date('格式字串',时间字段),例子:date('Y-m-d',$bqr[newstime])时间显示格式为"2008-10-01"。

实例1:如果信息为当天就加New标志

<ul>

[e:loop={栏目ID,显示条数,操作类型,只显示有标题图片}]

<?

$newimg="";

if(date("m-d",$bqr[truetime]) == date("m-d"))

{

    $newimg = "<img  src='New图片地址' alt="如何使用帝国CMS的灵动标签e:loop" >";

}

?>

<li>

<a href="<?=$bqsr[titleurl]?>" target="_blank"><?=sub($bqr[title],0,10,false)?></a><?=$newimg?>

</li>

[/e:loop]

</ul>

Copy after login

说明:首先定义newimg为空如果日期=当天则显示New图片,用在您想要的适当位置调用。

实例2:在灵动标签内使用SQL

[e:loop={'select * from phome_ecms_news where classid=72 order by id DESC limit 6',6,24,0}],注意倒数第二个参数为24,才可以使用SQL。

}

?>

                    <tr class="even">

                        <td class="title">

                            <h1><a href="<?=$bqsr[titleurl]?>" target="_blank"><?=sub($bqr[title],0,24,false)?></a> <?=$newimg?></h1>

                            <p class="intro">

                                <?=$bqr[smalltext]?>[<a title="阅读全文" href="<?=$bqsr[titleurl]?>" target="_blank">详细内容</a>]

                            </p>

                        </td>

                        <td><?=$bqr[myarea]?></td>

                        <td><?=date('Y-m-d H:i:s', $bqr[newstime])?></td>

                    </tr>
