Question

I have urls like this

example.com/model/id

example.com/image/123 (default rules)

I would rewrite it to:

example.com/category/123-this_is_encoded_title.html

My image model have following attributes:

• id
• title
• category
  …

I need to add category from model to url.
How can i add category name dynamic to the url?

Answer 1

it seems that you already using some default CUrlManager rules.

Add below rule at top of your rule list. (I am assuming your controller id is image)

'<category:\w+>/<id:\d+>-<title:\w+>.html'=>'image/view',

besides this, you have to change url creation in all places. You have to pass title and category values as the url params.

ex:

//Cleanup the title and category
$model->title = preg_replace("/[^\w+]/", '_', $model->title);
$model->category = preg_replace("/[^\w+]/", '_', $model->category);

//ex 1:
$this->redirect(array('view',
         'id'=>$model->id, 
         'title'=>$model->title, 
         'category' => $model->category
));

//ex 2:
echo CHtml::link('Title', array('view',
         'id'=>$data->id,
         'title' => $data->title, 
         'category' => $data->category
 ));

//ex 3:
$this->createUrl('image/view', array(
         'id'=>$image->id, 
         'title'=>$image->title, 
         'category' => $image->category
));

This answer explains what you need to do.
