Yii2 URL manager doesn't parse the rule - php

Question

I'm trying to use Yii URL manager to rewrite URLs like /site/about?tab=value to site/about/value or site/value.
My rule /<tab:\w+>' => 'site/about doesn't work. Here is the full URL manager code:
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' =>
[
'/' => 'site/index',
'/deals' => '/deal/deals',
'/<tab:\w+>' => 'site/about', //my rule
'/about' => 'site/about',
'/<action:[\-\w]+>' => 'site/<action>',
'/<module:\w+>' => '<module>/default/index',
'/<module:\w+>/<controller:\w+>/<id:\d+>' => '/<module>/<controller>/view',
'/<module:\w+>/<controller:\w+>/<id:\d+>/<action:[\-\w]+>/<entity_id:\d+>' => '/<module>/<controller>/<action>',
'/<module:\w+>/<controller:\w+>/<id:\d+>/<action:[\-\w]+>' => '/<module>/<controller>/<action>',
'/<controller:\w+>/<id:\d+>' => '<controller>/view',
'/<controller:\w+>/<id:\d+>/<action:[\-\w]+>/<entity_id:\d+>' => '<controller>/<action>',
'/<controller:\w+>/<id:\d+>/<action:[\-\w]+>' => '<controller>/<action>',
'/<controller:\w+>/<action:[\-\w]+>' => '<controller>/<action>',
'/<module:\w+>/<action:[\-\w]+>' => '<module>/default/<action>',
'/<module:\w+>/<controller:\w+>' => '<module>/<controller>/index',
],
And here is the widget code:
echo Nav::widget([
'items' => [
['label' => '1', 'url' => ['/site/about', 'tab' => '']],
['label' => '2', 'url' => ['/site/about', 'tab' => 'value']],
['label' => '3', 'url' => ['site/about', 'tab' => 'tariffs']],
['label' => '4', 'url' => ['site/about', 'tab' => 'team']],
['label' => '5', 'url' => ['site/about', 'tab' => 'documents']],
],
'options' => ['class' =>'nav-pills nav-stacked c-nav'],
]);

Answer 1

You should use named parameters, but you are naming the module/controller part.
You can only use these 3 reserved words:
module, controller, action
like the docs examples:
[
'<controller:(post|comment)>/<id:\d+>/<action:(create|update|delete)>' => '<controller>/<action>',
'<controller:(post|comment)>/<id:\d+>' => '<controller>/view',
'<controller:(post|comment)>s' => '<controller>/index',
]
But you are using <tab:\w+> that doesn't means anything for the rules section
Probably you could use:
'/site/about/<tab:\w+>' => 'site/about',
to catch URLs like:
web.com/site/about/bla
And then in the controller you could use the $tab variable like
namespace app\controllers;
class SiteController extends \yii\web\Controller {
public function actionAbout($tab)
{
return $this->renderContent("Hello $tab");
}
}
Hope this helps.

The problem was that some rules like /<controller:\w+>/<action:[\-\w]+>' => '<controller>/<action> and /<action:[\-\w]+>' => 'site/<action> were parsed earlier than mine, so I changed them.
Here is my solution:
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' =>
[
'/' => 'site/index',
'<tab:(about)>' => 'site/about',
'/about/<tab:(about|value|documents|tariffs|team)>' => 'site/about',
'/<action:(index|login|logout|contact|signup|request-password-reset|reset-password|thank-for-register|connect-inviteduser)>' => 'site/<action>',
'/<controller:(deal)>/<action:\w>' => 'deal/<action>',
'/<module:(trades)>' => '<module>/default/index',
'/<module:(trades)>/<controller:\w+>/<id:\d+>' => '/<module>/<controller>/view',
'/<module:(trades)>/<controller:\w+>/<id:\d+>/<action:[\-\w]+>/<entity_id:\d+>' => '/<module>/<controller>/<action>',
'/<module:(trades)>/<controller:\w+>/<id:\d+>/<action:[\-\w]+>' => '/<module>/<controller>/<action>',
'/<controller:\w+>/<id:\d+>' => '<controller>/view',
'/<controller:\w+>/<id:\d+>/<action:[\-\w]+>/<entity_id:\d+>' => '<controller>/<action>',
'/<controller:\w+>/<id:\d+>/<action:[\-\w]+>' => '<controller>/<action>',
'/<module:(trades)>/<action:[\-\w]+>' => '<module>/default/<action>',
'/<module:(trades)>/<controller:\w+>' => '<module>/<controller>/index',
],
],
The widget code:
<?php
echo Nav::widget([
'items' => [
['label' => 'О проекте', 'url' => ['/site/about', 'tab' => 'about']],
['label' => '5 причин работать через портал', 'url' => ['/site/about', 'tab' => 'value']],
['label' => 'Продвижение и тарификация', 'url' => ['site/about', 'tab' => 'tariffs']],
['label' => 'Проектная команда', 'url' => ['site/about', 'tab' => 'team']],
['label' => 'Документы', 'url' => ['site/about', 'tab' => 'documents']],
],
'options' => ['class' =>'nav-pills nav-stacked c-nav'],
]);
?>
And the action code:
public function actionAbout($tab = 'about')
{
$this->layout = '/about';
$tab = $tab == 'about' ? 'index' : $tab;
if (Yii::$app->request->isAjax)
return $this->renderPartial('about/' . $tab);
else
return $this->render('about/' .$tab);
}
