dede模板中直接写sql语句,关联sql调用

<div>{dede:php}$row = $GLOBALS['dsql']->GetOne("select id from dede_archives where typeid=4  order by rand() LIMIT 1"); 
 $row2 = $GLOBALS['dsql']->GetOne("select body from dede_addonarticle where aid=".$row['id']);
  $pattern='/key=(.*?)"/';
  $arr = preg_match($pattern, $row2['body'],$mc);
  $str = $mc[1];
  preg_replace("/\s/", "",$str);
  print_r('<iframe width="700" height="400" src="'.$str.'" frameborder="0" border="0" marginwidth="0" marginheight="0" scrolling="no" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>');{/dede:php}
</div>

上图匹配一个网址如图key的部分:

 

若dede:php标签不管用,下图(或dede:php  runphp='yes' )

模板引擎禁用标签中,去掉“php”即可;

另:plus下模板中可直接写php代码,如下:
