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 $tags = [
        &#39;articles&#39; => [&#39;attr&#39;=> &#39;field,id,limit,cid,order,returnname&#39;, &#39;close&#39;=>1]
    ];
    /**
     * 文章标签
     */
    public function tagArticles($tag, $content)
    {
        $id = $tag[&#39;id&#39;]?$tag[&#39;id&#39;]:&#39;vo&#39;;
        $order         = empty($tag[&#39;order&#39;]) ? "&#39;id DESC&#39;" : &#39;"&#39;.$tag[&#39;order&#39;].&#39;"&#39;;
        $returnname = &#39;article_data&#39;;
        $field = "&#39;&#39;";
        if (!empty($tag[&#39;field&#39;])) {
            if (strpos($tag[&#39;field&#39;], &#39;$&#39;) === 0) {
                $field = $tag[&#39;field&#39;];
                $this->autoBuildVar($field);
            } else {
                $field = "&#39;{$tag[&#39;field&#39;]}&#39;";
            }
        }
        $cid = "&#39;&#39;";
        if (!empty($tag[&#39;cid&#39;])) {
            if (strpos($tag[&#39;cid&#39;], &#39;$&#39;) === 0) {
                $cid = $tag[&#39;cid&#39;];
                $this->autoBuildVar($cid);
            } else {
                $cid = "&#39;{$tag[&#39;cid&#39;]}&#39;";
            }
        }
        $limit = "&#39;&#39;";
        if (!empty($tag[&#39;limit&#39;])) {
            if (strpos($tag[&#39;limit&#39;], &#39;$&#39;) === 0) {
                $limit = $tag[&#39;limit&#39;];
                $this->autoBuildVar($limit);
            } else {
                $limit = "&#39;{$tag[&#39;limit&#39;]}&#39;";
            }
        }else{
            $limit = &#39;0,5&#39;;
        }
        $parse = <<<parse
<?php
    \$$returnname = \app\common\model\Article::taglib_articles([
    &#39;field&#39;   => {$field},
    &#39;cid&#39;=>{$cid},
    &#39;limit&#39;=>{$limit},
    &#39;order&#39;=>{$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[&#39;field&#39;];
        $cid = $param[&#39;cid&#39;];
        $limit = $param[&#39;limit&#39;];
        $order = $param[&#39;order&#39;];
        $result = Article::where(&#39;cid&#39;, &#39;in&#39;,$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
    // +----------------------------------------------------------------------
    &#39;template&#39;               => [
        // 模板引擎类型 支持 php think 支持扩展
        &#39;type&#39;         => &#39;Think&#39;,
        // 模板路径
        &#39;view_path&#39;    => &#39;&#39;,
        // 模板后缀
        &#39;view_suffix&#39;  => &#39;html&#39;,
        // 模板文件名分隔符
        &#39;view_depr&#39;    => DS,
        // 模板引擎普通标签开始标记
        &#39;tpl_begin&#39;    => &#39;{&#39;,
        // 模板引擎普通标签结束标记
        &#39;tpl_end&#39;      => &#39;}&#39;,
        // 标签库标签开始标记
        &#39;taglib_begin&#39; => &#39;{&#39;,
        // 标签库标签结束标记
        &#39;taglib_end&#39;   => &#39;}&#39;,
        &#39;taglib_pre_load&#39;     =>    &#39;app\common\taglib\Cc&#39;, 
    ],

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!
