How to use wildcard in Symfony's url_for helper?

Given in routing.yml:

products:
url:   /products/*
param: { module: products, action: index }

How to fill wildcard part using url_for helper?开发者_如何学JAVA I mean somthing like:

<?= url_for('products/index?wildcard=somthingRandom') ?>

that generates URL:

/products/somethingRandom

Change your routing.yml to have a parameter in the matched URL:

products:
url:   /products/:wildcard
param: { module: products, action: index }

Then you can invoke url_for eg:

<?php echo url_for("@products?wildcard=somethingRandom"); ?>

(using @products means use the route named products in your routing.yml.)
