I have a rule in urlManager
'rules' => [
'products/<whatever:[-_0-9a-zA-Z]+>' => 'products/show',
],
and I have controller Products with actionShow()
public function actionShow($name)
{
var_dump($name);
echo 'actionShow is work';
}
But a have an Error: Bad Request (#400) Missing required parameters: name
How to transfer a product's $name to the controller, or how it can be obtained from the URL in the controller?
The CORRECT and COMPLETE answer is that you have to use the rule like below.
'rules' => [
'products/<name:[\-\w]+>' => 'products/show',
],
then in your products controller you don't need to pass $name in the parameter anymore that is why we defined in the rule and you have to use the
Yii::$app->request->queryParams['name']; or Yii::$app->request->get('name') to get the name of the product, your action will look like below
public function actionShow()
{
echo Yii::$app->request->get('name');
}
after doing all the settings above open brower and type
http://yourdomain.com/products/some-product
and it will show you
some-product
When you have to create a link to that page lets say in menu you have under products all products listed and you have to create a link to detail page for all of them i.e actionShow you would do it like below.
<?=Html::a($model->name,
Yii::$app->urlManager->createUrl([
'products/show',
'name'=>$model->slug
])
);
?>
I guess you should specify the name of your variable in the rule. You are calling it whatever, change it to name:
'rules' => [
'products/<name:[-_0-9a-zA-Z]+>' => 'products/show',
],
