Yii框架将变量从控制器传递到视图

Question

To pass variable to login view I use:

$this->render('login', array('model' => $model));

But I also need acces this variable in template part footer.php:

I try this:

$this->render('footer', array('model' => $model));

But when in footer.php I try acces variable I get error "undefined variable"

What is wrong ?

Answer 1

You can use controller class to pass variables in view template, for example

Controller :

 SomeController extends Controller { public function actionIndex() { $var1 = 'abc'; $var2 = '123'; $this->render('view', array('var1' => $var1, 'var2' => $var2, )); } } 

In view template file you can access these 2 variables ( $var1 & $var2) with its name :

 echo $var1; echo $var2 

Answer 2

Templates in yii are getting data from controller by $this reference.

<?php
SomeController extends Controller {
    public $something;

    public function init() {
        $this->something = 'qwerty';
    }
    public function actionA() {
        $this->render('view', array('model' => $model));
    }
}

In template:

<?php echo $this->something; ?>

Please take a look on default templates of yii. Breadcrimbs are displayed using property from controller, so this is propably the best way to achieve it.

mvc structure not redirect direct page.

you create first footer action and after redirect to page.

you see demo show login action in site_controller.php
