YII framework user friendly URL - php

Question

My yii PHP project has UserController and it has an action called actionView. I can access user view page using following URL
mysite.com/user/view/id/1
I want to change that one to
mysite.com/username
How Can I do it.
I know that i can simply create rule to be more user friendly to get url such as
mysite.com/user/username
But url scheme with database resource name as direct param (mysite.com/username) is whole different story.

Answer 1

Url rule:
array(
'<username:\w+>'=>'user/view',
)
Note that in such scheme, you must also create rules for all your controllers and place above rule at the end, so better prefix it with user:
array(
'user/<username:\w+>'=>'user/view',
)
Resulting url will be example.com/user/username
In action:
public function actionView($username) ...
Update:
To make rule which reacts on any input variable create custom url rule class, here is some example, modify to your needs:
class PageUrlRule extends CBaseUrlRule
{
public function createUrl($manager, $route, $params, $ampersand)
{
// Ignore this rule for creating urls
return false;
}
public function parseUrl($manager, $request, $pathInfo, $rawPathInfo)
{
// Ignore / url or any controller name - which could conflict with username
if($pathInfo == '/')
{
return true;
}
// Search for username or any resource in db
// This is for mongo so it should be tuned to your db,
// just check if username exists
$criteria = new EMongoCriteria();
$criteria->url->$lang = $url;
$criteria->select(['_id']);
$criteria->limit(1);
$model = PageItem::model();
$cursor = $model->findAll($criteria);
// Create route, instead of $url id can be used
$route = sprintf('content/page/view/url/%s', urlencode($url));
// If found return route or false if not found
return $cursor->count() ? $route : false;
}
}
Then place this rule in beginning of urlmanager config
'rules' => [
[
'class' => 'application.modules.content.components.PageUrlRule'
],
// Other rules here
Important: If user has username same as your controller, it will match username and controller will be inaccessible. You must forbid registering users with same names as controllers.
