HTTP header via annotations.
Installation
Download the Bundle
Open a command console, enter your project directory and execute the following command to download the latest version of this bundle:
$ composer require fourlabs/robots-bundle dev-master
This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Then, enable the bundle by adding the following line in the app/AppKernel.php file of your project:
<?php // app/AppKernel.php public function registerBundles() { $bundles = array( // ... new FourLabs\RobotsBundle\FourLabsRobotsBundle(), ); }
Usage
For more details see: https://developers.google.com/webmasters/control-crawl-index/docs/robots_meta_tag#using-the-x-robots-tag-http-header
Examples:
use FourLabs\RobotsBundle\Configuration\Robots; /** * @Robots(directive="index") */ public function showAction() { }
use FourLabs\RobotsBundle\Configuration\Robots; /** * @Robots(directive="nofollow", userAgent="googlebot") * @Robots(directive="noindex, nofollow" userAgent="otherbot") */ public function showAction() { }
use FourLabs\RobotsBundle\Configuration\Robots; /** * @Robots(directive="noarchive") * @Robots(directive="unavailable_after" value="25 Jun 2010 15:00:00 PST") */ public function showAction() { }
Configuration
Set block_all
to true to always set the X-Robots-Tag
header to none
. This will block all indexing and serving. Default: false
This is helpful to set an environment specific robots header so as to prevent search engines from indexing dev and test environments. Simple place the following configuration in your config_dev.yml and/or config_test.yml.
four_labs_robots: block_all: true
