Linking to a controller action inside the actual controller

(Suppose you are in the PostController/view and wants to link to PostController/create)
Just remove the 'controller' part from the string If you are linking to an action from another controller, use the syntax of the former examples.

Linking to a controller action from the site root

(Suppose you are inside a module and wants to make the link from a controller of the root application) In this case, add an slash "/" at the start of the string url This makes more sense if you are working with modules.

Linking to a controller action from another module

Replace below the module-id with desired module id .

Linking to a controller action from the same module

This is useful when you want to make absolute paths avoiding to use static module names.

Linking to a controller action via POST with confirmation dialog

Delete actions created using gii require the delete request be sent via POST to help prevent deleting objects by accident. Below is an example how to create a link that sends the request via POST and also asks for confirmation. Where you are redirected after the delete depends on your delete action. Note that the id link parameter below is a GET type parameter (submit URL will be something like http://example.com/post/delete/id/100). If you are using CSRF protection in your application do not forget to add csrf parameter to the htmlOptions array.

Linking to a controller action via POST with POST parameters

If you need to make POST request with arbitary link with additional POST parameters you should use following code (submit URL will be something like http://example.com/blog/deletePost/param/100).
CHtml::link(
            "<img src='".Yii::app()->baseUrl."/images/userimage.png"."' />",
            Yii::app()->createAbsoluteUrl("user/image",array("id"=>$this->user_id))
            );
