在Dede中使用PHP

一、基本用法：

{dede:field.descriptionrunphp=‘yes‘}

if(@me<>‘‘ )

@me = ‘<div class="intro">‘[email protected]‘</div>‘;

{/dede:field.description}

{dede:field name=‘imgurls‘ alt=‘图片输出区‘}

[field:pagestylerunphp=‘yes‘] @me= (@me==3 ? ‘<li>‘ : ‘‘);[/field:pagestyle]

<a href=‘[field:linkurl/]‘ [field:pagestyle runphp=‘yes‘] @me= (@me==3 ? ‘class="pic"‘ : ‘‘); [/field:pagestyle]>

<img src=‘[field:imgsrc/]‘ id=‘bigimg‘ [field:imgwidth /] alt=‘[field:alttext /]‘ border=‘0‘ />

</a>

<a href=‘[field:linkurl/]‘ [field:pagestyle runphp=‘yes‘]@me = (@me==3 ? ‘class="title"‘ : ‘‘);[/field:pagestyle]>

[field:title /]

</a>

[field:pagestyle runphp=‘yes‘] @me = (@me==3 ? ‘</li>‘ : ‘‘); [/field:pagestyle]

{/dede:field}

二、高级用法：

1、dede后台->系统->系统设置->系统基本参数->其它选项->把“模板引擎禁用标签”中的"php"标签去掉，保存

2、使用：

{dede:php}

echo ‘php‘;

{/dede:php}

{dede:php}

$result = mysql_query("select * from bbs_forum_forum t1 left join bbs_forum_forumfield t2 on t1.fid=t2.fid where status=1 and type=‘forum‘ order by t1.displayorder asc");

while($row = mysql_fetch_assoc($result)){

echo ‘<table cellpadding="0" cellspacing="0" width="100%" border="0" class="pbw_bbsTable">‘;

echo ‘<tr>‘;

echo ‘<td width="64">‘;

echo ‘<a href="/bbs/forum.php?mod=forumdisplay&fid=‘.$row[‘fid‘].‘"><img src="/bbs/data/attachment/common/‘.$row[‘icon‘].‘" width="46" height="46" style="border:1px solid #000;" /></a>‘;

echo ‘</td>‘;

echo ‘<td width="465">‘;

echo ‘<div class="pbw_bbsTitle"><a href="/bbs/forum.php?mod=forumdisplay&fid=‘.$row[‘fid‘].‘">‘.$row[‘name‘].‘</a><span>(‘.$row[‘threads‘].‘)</span></div>‘;

echo ‘<div class="pbw_bbsBrief">‘.$row[‘description‘].‘</div>‘;

echo ‘<div style="color:red;">‘.$row[‘rules‘].‘</div>‘;

$moderators = explode("    ", $row[‘moderators‘]);

$moderators = implode(",", $moderators);

echo ‘<div class="pbw_bbsBanzhu">版主：‘.$moderators.‘</div>‘;

echo ‘</td>‘;

echo ‘<td width="90">&nbsp;</td>‘;

echo ‘<td width="120" align="center">‘;

echo $row[‘threads‘].‘/‘.$row[‘posts‘];

echo ‘</td>‘;

echo ‘<td>‘;

$lastpost = explode("    ", $row[‘lastpost‘]);

echo ‘<a href="/bbs/forum.php?mod=viewthread&tid=‘.$lastpost[0].‘#lastpost">‘.$lastpost[1].‘</a>(<a href="/bbs/home.php?mod=space&username=‘.$lastpost[3].‘" style="color:#369">‘.$lastpost[3].‘</a>)<br />‘;

echo date("Y-m-d H:i:s", $lastpost[2]);

echo ‘</td>‘;

echo ‘</tr>‘;

echo ‘</table>‘;

}
