Example analysis of widget extension usages under thinkphp,

This example describes the use of widget extensions under thinkphp. Share to everyone for your reference, as follows:

The widget extension is used to output different content on the page as needed, and the widget extension is defined as the Widget class library defined under the project's Lib\widget directory, for example, a widget that shows the most recent comment is defined below:

Located in lib\widget\showcommentwidget.class.php

The Widget class library needs to inherit the widget class and must define the Render method implementation, for example:

The Render method must return the string information to be output using return instead of the direct output.

Widgets can also invoke the RenderFile method of the Widget class, rendering the template and outputting it.

Build the widget directory in the project's Lib directory, with the action directory sibling.

Establish TestWidget.class.php:

Class Testwidget extends widget{public  function render ($data) {    //print_r ($data);    $data [' id ']= $data [' id '];    $data [' Info ']= $data [' info '];    $content = $this->renderfile (' index ', $data);    Print_r ($content);    return $content;  }}

Set up the corresponding test folder under this directory, and put the HTML page of the $this->rendfile call below.

index.html information for displaying data by using loops

  This is the template page for the widget call  
 
   
  
   //NOTE: The ID corresponds to the key value of the $data    {$VO}  
 
    
  
 
   
  
   //info The key value    
  corresponding to the $data 
   
    
         {$v}    
  
     
 
  

Action method:

IndexAction.class.php

The code is as follows:

Class Testaction extends action{public  function Index () {    $info =array (Array ("1", "AA", "title"), Array ("2", " BB "," Title2 "));    $this->assign ("info", $info);    $this->display ();  }}

Action is called by the index.html of the HTML page in the TPL

The code is as follows:

This is the action of the Test call.
Arguments passed to TestWidget.class.php, to be passed in array format

Run IndexAction.class.php

The page appears as follows:

So we're going to include the contents of the show.html.
