Symfony Redirect Bundle

Configure redirections after a migration or structural changes to your app/website.

It catches exception events, if they are of type NotFoundHttpException it will look for a configured rule and return a RedirectResponse response to redirect the user.

Works for Symfony ^4.2 or ^5.0 with PHP >= 7.1.3 and <8.2

It's been designed to be as unobtrusive as possible since the need to do this sort of thing is often temporary - Google recommends leaving them in place for a year. Just include the bundle and add a block of configuration for your redirect rules.

Installation

Install via Composer

$ composer require smirnov-tk/redirect-bundle

Include the bundle in bundles.php

# config/bundles.php

return [
    // All your bundles
    
    Autologic\Bundle\RedirectBundle\AutologicRedirectBundle::class => ['all' => true],
];

Configuration

Basic Usage

# app/config/packages/autologic_redirect.yaml

autologic_redirect:
  rules:
    - { pattern: '/old-route/', redirect: 'domain.com/new-route' }

pattern (string, required)

Use regular expressions to match the full URI being requested. The service catches 404 exceptions, uses preg_match to find a rule matching the missing page's URI before throwing the 404 in the event it cannot match.

redirect (string, required)

The fully qualified redirect URI. The bundle will set the protocol (http/https) based on the incoming original request so it ports from dev to prod easily.

full_url (bool, optional)

Defines whether to match pattern on full URL (with scheme, domain, path and query) or only path and query (_default: false)

status (int, optional)

Set the status code (default: 301) for the redirection. Tip: use 302 while debugging to avoid 301 permanent redirects from being cached in the browser.

forwarding (bool, optional)

Append the original route to the redirection (default: false). Useful in the case that other services/applications have their own redirect logic in place or route structure is the same on a different domain or path.

absolute (bool, optional)

Force absolute or relative redirects (default: null/auto). If left unset, it will detect a hostname in the redirect and either use the original request host if the redirect does not contain a host or use the redirect verbatim if it does.

protocol (string, optional)

Force the redirect protocol (default: null/auto). If left unset, it will detect the protocol from the original request and use that.

Other Examples

# app/config.yml

autologic_redirect:
  rules:
    # custom status code
    - { pattern: '/old-route/', redirect: 'domain.com/new-route', status: 302 }
    # forwarding: this will redirect to domain.com/new-route/old-route
    - { pattern: '/old-route/', redirect: 'domain.com/new-route', forwarding: true }
    # absolute: will force relative or absolute redirects
    # if false it will redirect to the route on the current host
    - { pattern: '/old-route/', redirect: '/new-route', absolute: false }
    # protocol: will force the protocol
    - { pattern: '/old-route/', redirect: '/new-route', protocol: 'ftp://' }
    # priority: this first rule will match first when a user visits /old-route/sub-route, the second acting as a fallback
    - { pattern: '/.*old-route\/sub-route', redirect: 'domain.com/new-route/sub-route' }
    - { pattern: '/.*old-route/', redirect: 'domain.com/new-route' }
    # match subdomains and more complex patterns and use parameters
    - { pattern: '/au\..+?\.[^\/]+.*blog\/old-australian-blog-post-on-any-domain-of-subdomain/',
        redirect: 'au.%base_domain%/news/new-australian-news-article',
        full_url: true
      }

Logging

To enable logging of unmatched 404 errors, just inject a logger into the listener service in your services.yml:

# app/services.yml

services:
  autologic_redirect.event.redirect_listener:
    class: Autologic\Bundle\RedirectBundle\Event\RedirectListener
    arguments:
      - '@autologic_redirect.service.redirect_service'
      - '@logger'
    tags:
      - { name: kernel.event_listener, event: kernel.exception }

This will log at notice level to help sniff out 404s that don't have any redirection rules in place.
