I've created a view in views/sites/example.php
<?php
use yii\helpers\Html;
?>
<?= Html::encode($message) ?>
Then in SiteController.php I have added
public function actionExample($message = 'Hello')
{
return $this->render('example', ['message' => $message]);
}
In main.php, the urlManager is configured
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => array(
'<controller:\w+>/<id:\d+>' => '<controller>/view',
'<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
'<controller:\w+>/<action:\w+>' => '<controller>/<action>',
),
],
when I try to access the page at localhost/example, I get a 404. What have I missed??
In rules section of urlManager part of code there are rules for which URL is checked to determine controller, action etc.
Because your action is in SiteController it can be accessed by //localhost/site/example/ url (rule'<controller:\w+>/<action:\w+>' => '<controller>/<action>'
).
So to make your action accessible via //localhost/example/ url another rule should be added to rules section.
If you add'example' => 'site/example',
to rules your action will be accessible on desired URL.
