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

<?php echo CHtml::link('Link Text',array('action')); ?>

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

<?php echo CHtml::link('Link Text',array('/controller/action')); ?>

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 .

<?php echo CHtml::link('Link Text',array('/module-id/controller/action')); ?>

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.

<?php echo CHtml::link('Link Text',
                           array('/{$this->module->id}/controller/action')); 
?>

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).

<?php echo CHtml::link('Delete',"#", 
                    array("submit"=>array('delete', 'id'=>$data->ID), 
                   'confirm' => 'Are you sure?')); 
?>

If you are using CSRF protection in your application do not forget to add csrf parameter
to the htmlOptions array.

<?php echo CHtml::link('Delete',"#", 
                          array("submit"=>array('delete', 'id'=>$data->ID),
                          'confirm' => 'Are you sure?', 'csrf'=>true)); 
?>

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).

<p><?php echo CHtml:link('Delete blog post', '#', array(
    'submit'=>array('blog/deletePost', 'param'=>100),
    'params'=>array('id'=>$post->id, 'status'=>Post::STATUS_DELETED_BY_OWNER),
    'csrf'=>true,
)); ?></p>

CHtml::button() method 
CHtml::link(
            "<img src='".Yii::app()->baseUrl."/images/userimage.png"."' />",
            Yii::app()->createAbsoluteUrl("user/image",array("id"=>$this->user_id))
            );
