一、安装了扩展
二、在index 应用了写了自定义标签库的实例
namespace app\index\common\taglib;
use think\template\TagLib;
use think\facade\Db;
class Qdcms extends TagLib
{
protected $tags = [
'myppt' => ['attr'=>'title,big_img,small_img,limit,id,typeid,link,des,order,status','close'=>1],
];
// 幻灯片调用
public function tagMyppt($tag,$content) {
$limit=isset($tag['limit']) ? $tag['limit']:'';
$typeid=isset($tag['typeid']) ? $tag['typeid']:'';
$order = empty($tag['order']) ? "'sort ASC'" : '"'.$tag['order'].'"';
$big_img=isset($tag['big_img']) ? $tag['big_img']:'';
$small_img=isset($tag['small_img']) ? $tag['small_img']:'';
$link=isset($tag['link']) ? $tag['link']:'';
$des=isset($tag['des']) ? $tag['des']:'';
$status=isset($tag['status']) ? $tag['status']:'';
$str='<?php ';
if($limit) {
$str .='$myppt=Db::name("hdad")
->where(array("hdadpos_id"=>'.$typeid.'))
->where(array("status"=>1))
->limit('.$limit.')
->order('.$order.')
->select();';
} else {
$str .='$myppt=Db::name("hdad")->select();';
}
$str .='foreach($myppt as $k=>$v):?>';
$str .=$content;
$str .="<?php endforeach; ?>";
return $str;
}
}三、在index应用里，建立了config 配置，view.php 'taglib_pre_load' => 'app\index\common\taglib\Qdcms',四、模板中调用。 {qdcms:myppt limit='8' typeid='1' order='sort asc'}
<li><a href="{$v.link}"><img src="{$v.big_img}" alt="{$v.title}"/></a></li>
{/qdcms:myppt} 然后就报错了：Class 'Db' not found
请教大家了 ！谢谢
