Yii::$app->plugin->render('Hook_Name');   # Name the Hook Position and told it to your plugin developers. 

Plugin Develop

Create A Plugin

For Create a plugin, you need to inherit the class Plugin.

And the class name and class file name should end with the word Plugin. For expamle, file ExamplePlugin.php:

class ExamplePlugin extends Plugin {
    //codes here
}

The word Example (without word Plugin) is the plugin's identify (case sensitive).

Implement The Plugin

To implement the plugin and makes it work, you should inherit these method and initialize some properties.

class ExamplePlugin extends Plugin {

    public function init() {                    #initialize,config plugin's info, required
        // set plugin's info
        $this->identify = 'Example';            #required, the Unique id for this plugin.
        $this->name = 'Example Plugin';         #required, plugin's name for display.
        $this->version = '1.0';
        $this->description = 'description here';
        $this->copyright = '© Robin <[email protected]>';
        $this->website = 'http://example.com';   
        $this->icon = 'icon.png'; #max to 72*72, if not set a default icon will display in the admin cp;
    }

    // return hooks array which this plugin want to hook, the value is the method's name
    // for the hook.
    public function hooks(){
        return array(
            //'Hook Position Name' => 'hook method';
            'Hook_Index_Header' => 'header',
        );
    }

    // method for hook
    public function header(){
        // some codes here
        echo 'This will echo a sting at position Hook_Index_Header';
    }

    // If you want to display a page with an url instead of render as a widget,
    // you need to write a method begin with the word "action", the word after 
    // "action" is the action's name.
    // e.g.:
    public function actionPage() {
        echo "This action have a url like this (with url rewrite):";
        # domain/plugin<Module>/plugin<controller name>/index<router action name>
        # ?id=xx<plugin identify>&action=xxx<action name>
        echo "You_Domain.com/plugin/plugin/index?id=example&action=page";

        #You can create this url by call method 'createUrl'
        echo $this->createUrl('page',array('param'=>'test'));
    }

    public function actionExample(){
        # this action is named with plugin's identify,
        # param $action could be empty or false value
        echo $this->createUrl();
    }      

    // If your plugin allow to set configs at the admin control panel
    // You need to inherit this:

    public function admincp() {
        // You can put codes here.
        // Like some inputs
        $this->setSetting('key','value');   # write setting
        echo $this->getSetting('key');      # read setting
    }

    // Here you can put some code at the Installation and Uninstallation
    public function install() {
        //codes here
        $sql = "create `tbl_xxxxxx` .....";     # write sql with a table prefix 
        $this->query($sql,'tbl_');              # and pass it at method query
                                                # as default, it is 'tbl_'
        return true; #This method need to return true, or the installation will fail.
    }

    public function uninstall() {
        // just like the method install.
        return true; #This method need to return true, or the uninstallation will fail.
    }

    // Then, you created a simple plugin
    // For advanced usage, see demos
}
