灵动标签 (e:loop)
格式:
[e:loop={栏目ID/专题ID,显示条数,操作类型,只显示有标题图片,附加SQL条件,显示排序}]
模板代码内容
[/e:loop]
例子:
<
table
width
="100%"
border
="0"
cellspacing
="1"
cellpadding
="3"
>
[e:loop={栏目ID/专题ID,显示条数,操作类型,只显示有标题图片,附加SQL条件,显示排序}]
<
tr
><
td
>
<
a
href
="<?=$bqsr[titleurl]?>"
target
="_blank"
>
<?
=$bqr[title]
?>
</
a
>
(
<?
=date('Y-m-d',$bqr[newstime])
?>
)
</
td
></
tr
>
[/e:loop]
</
table
>
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
本功能实现调用信息时候如果是当天发布的最新信息显示New标志图片。
<
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"))
{
$newimg = "<img src='New图片地址'>";
}
?>
<
li
>
<
a
href
="<?=$bqsr[titleurl]?>"
target
="_blank"
>
<?
=sub($bqr[title],0,10,false)
?>
</
a
>
<?
=$newimg
?>
</
li
>
[/e:loop]
</
ul
>
说明:首先定义newimg为空如果日期=当天则显示New图片,用<?=$newimg?>在您想要的适当位置调用。
实例2:在灵动标签内使用SQL
[e:loop={'select * from phome_ecms_news where classid=72 order by id DESC limit 6',6,24,0}],注意倒数第二个参数为24,才可以使用SQL。
[e:loop={'select * from [!db.pre!]ecms_news where classid=72 and type='开发商' order by id DESC limit 6',6,24,0}]
<
li
class
="class1"
>
<
a
href
='http://www.hkqipilang.acafa.com/'
target
=_blank
title
='<?=$bqr[title]?>'
>
<?
=$bqr[title]
?>
</
a
>
<
div
class
="top_div_myAcafa_u"
>
<?
=$bqr[address]
?>
<
br
/>
业务范围:
<?
=$bqr[smalltext]
?>
</
div
>
</
li
>
[/e:loop]
实例3:如果信息带有图片信息,则标题上带有图片标志
[e:loop={'selfinfo',20,0,0}]
<?
$newimg="";
if(!empty($bqr[titlepic]))
{
$newimg="<img src='http://bbs.zhnews.net/bbs/static/image/filetype/image_s.gif' />";
}
?>
<tr class="even">
<td class="title">
<h1><a href="<?=$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', $bqr[newstime])?></td>
</tr>
[/e:loop]
显示字段用<?=$bqr[字段]?>,$bqsr就几个变量:
- $bqsr[titleurl]:标题链接
- $bqsr[classname]:栏目名称
- $bqsr[classurl]:栏目链接
- $bqsr[titleurl]:标题链接
- $bqsr[classname]:栏目名称
- $bqsr[classurl]:栏目链接
- 除了这几个其他的都用$bqr。
