Instance of Custom Tag Library under ThinkPHP Grouping

This paper describes the implementation method of custom tag library under ThinkPHP grouping. Share it for your reference. The details are as follows:

The custom tag library should be located in the ThinkPHP\\ Extend\\ Driver\\ TagLib directory

1 The new tag class library file name is TagLibBlog. class. php.

2 Edit the newly created class library file just now, create a new class, and inherit the parent class of TagLib

import('TagLib');

class TagLibBlog extends TagLib {

}

3 Declare 1 protected member variable $tags in the class

class TagLibBlog extends TagLib {

   protected $tags =array(

       'mynav'=>array('attr'=>'limit,order','close'=>1)

       /* www.ofstack.com

        Here $tags Within an array , Every unit is also every 1 Bank representative 1 Tags , For example {dede:article}, We also define it here 1 A mynav,

        And then every 1 The key name of the row label is the label name , The key value is 1 Array of numbers , The array contains two cells , No. 1 1 One is attr Is the attribute in the tag , Separated by commas ,

        Such as num,typeid Wait ,close If the value of is 0 It is a non-closed label ,1 The word is closed, which means to use </mynav> To end 

       */

   );

}

After defining the label, we need to realize the function of the label. Here, we declare a function directly under the class file, which starts with _ and ends with the label name mynav

public function _mynav($attr,$content){

   $attr=$this->parseXmlAttr($attr);

   

   import('@.Class.Tool');

   $categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();

   $categories=Tool::formatMultiArray($categories);

   

   $str='';

   for($i=0;$i<count($categories);$i++){

       $model=array(

           '/[field.id]/',

           '/[field.name]/'

       );

       $replace=array(

           $categories[$i]['id'],

           $categories[$i]['name']

       );

       $str.=preg_replace($model,$replace,$content);

   }

   

   return $str;

}

After defining the label, you need to load the tag library in the project public configuration file
config.php

// Load Tag Library 

'APP_AUTOLOAD_PATH'=>'@.TagLib',

'TAGLIB_BUILD_IN'=>'Cx,Blog',

 The complete source code of tag library is as follows: 

<?php

import('TagLib');

class TagLibBlog extends TagLib {

   

   protected $tags=array(

       'mynav'=>array('attr'=>'limit,order','close'=>1)

   );

   

   public function _mynav($attr,$content){

       $attr=$this->parseXmlAttr($attr);

       

       import('@.Class.Tool');

       $categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();

       $categories=Tool::formatMultiArray($categories);

       

       $str='';

       for($i=0;$i<count($categories);$i++){

           $model=array(

               '/[field.id]/',

               '/[field.name]/'

           );

           $replace=array(

               $categories[$i]['id'],

               $categories[$i]['name']

           );

           $str.=preg_replace($model,$replace,$content);

       }

       

       return $str;

   }

   

}

?>

Tests in templates:

<mynav limit="0,10" order="sort asc">

   <a href="[field.id]">[field.name]</a><br/>

</mynav>

I hope this article is helpful to everyone's ThinkPHP framework programming.
