学着写了一下,终于搞定了,顺便分享一下!
taglib是tp框架自定义标签功能,如果你用过cms,肯定见过类似:
{dede:arclist typeid='' row='' col='' titlelen='' infolen='' orderby='' keyword=''} ssss... {/dede:arclist}
或者:
{pc:content action="lists" cache="3600" num="20" page="$page"} {/pc}
这样的操作,这对于开发工作是挺方便的,所以觉得有必要看下tp的taglib,教程如下:
1 、在common(我是在common,你自己看,反正是用命名空间载入)里新建目录taglib
2、在taglib里新建Cc.php 继承think的Tglib,代码如下:
<?php /** * Created by PhpStorm. * User: lichenchen * Date: 2018/3/25 * Time: 下午8:34 */ namespace app\common\taglib; use think\template\TagLib; use app\common\model\Article; class Cc extends TagLib { protected $tags = [ 'articles' => ['attr'=> 'field,id,limit,cid,order,returnname', 'close'=>1] ]; /** * 文章标签 */ public function tagArticles($tag, $content) { $id = $tag['id']?$tag['id']:'vo'; $order = empty($tag['order']) ? "'id DESC'" : '"'.$tag['order'].'"'; $returnname = 'article_data'; $field = "''"; if (!empty($tag['field'])) { if (strpos($tag['field'], '$') === 0) { $field = $tag['field']; $this->autoBuildVar($field); } else { $field = "'{$tag['field']}'"; } } $cid = "''"; if (!empty($tag['cid'])) { if (strpos($tag['cid'], '$') === 0) { $cid = $tag['cid']; $this->autoBuildVar($cid); } else { $cid = "'{$tag['cid']}'"; } } $limit = "''"; if (!empty($tag['limit'])) { if (strpos($tag['limit'], '$') === 0) { $limit = $tag['limit']; $this->autoBuildVar($limit); } else { $limit = "'{$tag['limit']}'"; } }else{ $limit = '0,5'; } $parse = <<<parse <?php \$$returnname = \app\common\model\Article::taglib_articles([ 'field' => {$field}, 'cid'=>{$cid}, 'limit'=>{$limit}, 'order'=>{$order} ]); ?> {volist name="{$returnname}" id="{$id}"} {$content} {/volist} parse; return $parse; } }
这里演示的是一个文章标签 articles里面调用了Article模型的静态方法taglib_articles , 顺便也贴下代码吧,就是根据条件查询的
public static function taglib_articles($param) { $field = $param['field']; $cid = $param['cid']; $limit = $param['limit']; $order = $param['order']; $result = Article::where('cid', 'in',$cid)->field($field)->limit($limit)->order($order)->select(); return $result; }
之后,在tp的配置文件里,加一条配置载入自定义标签文件的
// +---------------------------------------------------------------------- // | 模板设置 // +---------------------------------------------------------------------- 'template' => [ // 模板引擎类型 支持 php think 支持扩展 'type' => 'Think', // 模板路径 'view_path' => '', // 模板后缀 'view_suffix' => 'html', // 模板文件名分隔符 'view_depr' => DS, // 模板引擎普通标签开始标记 'tpl_begin' => '{', // 模板引擎普通标签结束标记 'tpl_end' => '}', // 标签库标签开始标记 'taglib_begin' => '{', // 标签库标签结束标记 'taglib_end' => '}', 'taglib_pre_load' => 'app\common\taglib\Cc', ],
就是:'taglib_pre_load' => 'app\common\taglib\Cc', 这条 。
之后就可以在模版里使用了
{cc:articles cid="1" field='id,title' limit="2" order="id asc" id="vo"}25edfb22a4f469ecb59f1190150159c6f1b3ba8846c179e65eb68da95b01a812{$vo.title}5db79b134e9f6b82c0b36e0489ee08edbed06894275b65c1ab86501b08a632eb{/cc:articles}
很方便吧,整了两个小时,才写好,特此记录一下,希望也能帮助到需要的朋友们!
