Style admin page in Yii

Im here again with a question about yii framework.

I've got a page under views/myviewname/admin.php. I've got a page under views/myotherviewname/admin.php. Now i want to give those pages another style. But how do i do that?

I've created a page under themes/classis/views/myviewname/admin.php and in that file i got this:

<?php /* @var $this Controller */ ?>
<?php echo $content; ?>

But i get an error. Because $content is not defined.

How do i style those pages? Would be nice if i can style all admin pages at once.

First of all, this is undeniable that $content variable will be known as undefined, since it can only be used in Layouts, not Views.

As you probably know, if you already have set a theme for your application(in main config file by 'theme'=>'myTheme'), Yii looks for that into themes/myTheme and all views will be rendered in themes/myTheme/views/x/y.php instead of views/x/y.php. Also, your layouts will be overridden by layouts located into themes/myTheme/layouts.

Now, lets assume that we want to create 2 themes:

  1. DarkTheme
  2. LightTheme

We should create structures like below:

+themes
    +darkTheme
        +views    
             +layouts
                 +main.php
                 +myLayout1.php
                 +myLayout2.php
             +myController
                 +myView1.php
    +lightTheme
        +views    
             +layouts
                 +main.php
                 +myLayout1.php
                 +myLayout2.php
             +myController
                 +myView1.php

We have a main.php which holds our base theme structure(skeleton), and 2 layouts named myLayout1.php and myLayout2.php respectively. Also we already defined a default layout into our base controller(Usually Controller.php) like below:

public $layout='//layouts/myLayout1';

Now, we have a main layout which shows everything inside myLayout1 by default. We can change layout in out action like below:

$this->layout="myLayout2";

Also we can change application theme like below:

Yii::app()->theme="lightTheme";

Note: Theme name is case-sensitive. If you attempt to activate a theme that does not exist, Yii::app()->theme will return null.

Above codes can be written into beforeAction() method or every action. Please note that, if you render myView1($this->render('myView1')) and if the theme is set to darkTheme, Yii will render themes/darkTheme/views/myController/myView1.php instead of views/myConteoller/myView1.php.

To be more clear, $content will be used in layouts. Also, this is remarkable that, $content will be replaced by everything inside a view. So if you want to modify the whole page's schema, you must modify main.php layout. In front, if you want to modify the style of a view's content, you need to modify your layout.
