Yii2 UrlManager rules

Question

What would be the Urlmanager rule for changing a url like site/product?name=[name] to product/[name]?

I tried

'<action:\w+>' => 'site/<action>',
'product/<id:\d+>' => 'product',

But it gives me a 404

Answer 1

Before answering to your question a short explain what is wrong. You try to pass alpha chars to an action that handles only integers. The rule 'product/<id:\d+>' indicate that the url should be like:

product/1
product/777
product/8888

The regular expression \d+ limits this url part to an integer.

Answer

For url like product/[name], you should add this pattern:

//...
'product/<name:[\w]+>' => 'product/item',
//...

Where 'product/<name:[\w]+>' will match any url like:

product/any
product/alpha
product/productname

The <name:[\w]+> will be the parameter that will hold matched url part and and creates a variable named $name that will contain only the alpha chars, due the regular expression [\w]+. This variable will be passed to controller action.

And 'product/item' is the controller / action that will handle request, in this example is ProductController and actionItem with parameter $name.

Now in ProductController you need to add an action:

//...
/**
 * Handle products by name
 * @param string $name
 */
public function actionItem($name) {
   // ... do stuff here
}
//...
