This extension helps to prevent unwanted parameters in the canonical URL. ### Extension plugin namespaces [](#extension-plugin-namespaces) By default parameters within the namespaces from active extensions (e.g. `tx_news_pi1`) using Extbase are allowed. This still allows parameters not used by these extensions like `tx_news_pi1[wtf]=seo`. If you need to include third-party parameters or parameters for extensions based on `\TYPO3\CMS\Frontend\Plugin\AbstractPlugin` (aka *pi based*) or need to be very strict, disable the setting and/or use the explicit whitelist. ### Explicit whitelist [](#explicit-whitelist) In addition to or as replacement for the allowed namespaces from active extension Extbase plugins (see above), you can set a whitelist if you need to allow additional parameters or want to specify exactly which parameters are allowed. Go to Admin Tools > Settings > Extension Configuration and select *seo\_canonical\_guard* and set the allowed parameters or parameter namespaces as follows: ``` parameter1, parameter2, namespace_xy\[(.*?)\], namespace_yz\[(explicit1|explicit2)\] ``` You can add a list of single parameters or use regular expressions (you can omit the `/…/` around, but you have to escape special characters). Requirements ------------ [](#requirements) The extension depends on the TYPO3 core *seo* extension. Installation ------------ [](#installation) Require the latest package: ``` composer require wazum/seo-canonical-guard ``` Inspiration ----------- [](#inspiration) The extension is inspired by which definitely should be installed too if you use the `addQueryString` when creating links with TypoScript!
