Introduction to commonly used functions:

Text interception: esub (string, interception length), example: esub($bqr[title],30) intercepts the first 30 characters of the title.

Time format: date('format string', time field), example: date('Y-m-d',$bqr[newstime]) The time display format is "2008-10-01".

Example 1: If the information is for the current day, add the New logo

This function implements the display of the New logo image if it is the latest information released that day when calling information.

The code is as follows:

<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>

Instructions: First define newimg as empty. If the date = today, then the New picture will be displayed. Use <?=$newimg?> to call it at the appropriate position you want. .

Example 2: Use SQL in the smart tag

[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。

Copy the code The code is as follows:

[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"><?=$bqr[address]?>
业务范围: <?=$bqr[smalltext]?></div>
</li>
[/e:loop]  

Example 3: If the information has image information, the title will have the image The code for the sign

is as follows:

[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]

To display the field, use <?=$bqr[field]?>, $bqsr has only a few variables:

$bqsr[titleurl ]: Title link

$bqsr[classname]: Column name

$bqsr[classurl]: Column link

$bqsr[titleurl]: Title link

$bqsr[classname]: Column name
