Yii 1.1: metadata

Getting names of controllers/actions/modules/models in your app


Yii Metadata component helps to get information about models,controllers and actions from your application

Installation & Usage

1. Place Metadata.php to directory with components of your application (your_app_dir/protected/components/) or to extensions (your_app_dir/protected/extensions/)

2. Add 'metadata' element to 'components' in your application config (your_app_dir/protected/config/main.php):


If you place Metadata.php to extensions, then you should write 'class'=>'ext.Metadata' instead of 'class'=>'Metadata'

3. Use:

$user_actions = Yii::app()->metadata->getActions('UserController');
   var_dump($user_actions); #Get actions of 'UserController'
   $controllers = Yii::app()->metadata->getControllers(); #You can specify module name as parameter
   var_dump($controllers); #Get list of application controllers
   $controllersWithActions = Yii::app()->metadata->getControllersActions('user'); #if no $module param, controllers&actions of application will returned
   var_dump($controllers); #Get controllers and their actions of module 'user'
   $models = Yii::app()->metadata->getModels(); #You can specify module name as parameter
   var_dump($models); #Get list of models application 
   $modules = Yii::app()->metadata->getModules();



  1. If some modules in your app have controllers with same names, MetaData will raise fatal error, when you will try to get information about controllers of both this modules.

  2. getModules method can not find modules inside other modules. (will fixed in next ver.)

  3. MetaData cannot find information about controller actions, specified by actions() method (will fixed in next ver.)

Issue Fix

You wont get that fatal error every time if you parse the .php file as text instead of including it and reflecting it. Replace the getActions function with this:

public function getActions($controller, $module=null)
    if ($module!=null){

        throw new Exception('no file found at '.$path.DIRECTORY_SEPARATOR.$controller.'.php');

        $actions = array();
        $file = fopen($path.DIRECTORY_SEPARATOR.$controller.'.php', 'r');
        $lineNumber = 0;
    while( feof($file)===false ){
        $line = fgets($file);
        preg_match('/public[ \t]+function[ \t]+action([A-Z]{1}[a-zA-Z0-9]+)[ \t]*\(/', $line, $matches);
        if( $matches!==array() ){
            $name = $matches[1];
            $actions[] =  $matches[1];

    return $actions;

nested module may not support

great job! useful for auth system , auto list all available actions , controllers ,modules , and then assign it to some role ,you don't need input it manually anymore and can choice it from a tree list view under this extension helping .:)

and............ any one test it on nested modules circumstance? the nest version should support the nested module situation . i roughly read the code and found that it doesn't support nested modules .

designation of this exstension

For example you can use it in your Yii based CMS to get list of available modules/controllers/actions and actions dinamically. p.s.: Sorry for my english, it isn't good. Usually i speak russian. Correct me please if you see stange text in documentation :)
