Extend existing models

To extend an already existing extbase model with a detail view, e.g. news or job offers, and offer the evaluation of this records, easily complete the following two steps.

If the hreflang tag is enabled in TypoScript, the hreflang tag is set for all existing languages of the extended extbase item (not for the languages of the detail page). It checks the languages for the extbase item, which is given by the get parameter from the page Yaml config in step 2. If a fallback item is displayed because of sys_language_mode content_fallback, the hrefang tag will be removed and the canonical tag points to the url of the displayed fallback item.

1. Add a Yaml Config File

Add the following yaml content to a file EXT:myext/Configuration/CsSeo/config.yaml.


   # new index and table name of the model

      # if the get parameter is set in the URL the cs_seo properties will be shown
      enable: 'GP:tx_myext_pi1|mymod'

      # if the model already has fields like title etc. define them as fallback

         # cs_seo title field fallback = mymod title field
         title: title

         # cs_seo description field fallback = mymod description field
         # also more fields possible within curly brackets, e.g. description: {teaser} - {company}
         description: description

      # enable evaluation for mymod

         # additional params to initialize the detail view, the pipe will be replaced by the uid
         getParams: >-

         # detail pid for the current records, only if set the table will be available
         detailPid: 100

You have the possibility to merge multiple config files via imports.

2. Register the config file

Register the config file in your ext_localconf.php.

// Copy the current file
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['cs_seo']['yamlConfigFile'] = 'EXT:myext/Configuration/CsSeo/config.yaml';

Clear the system cache and done. A new tab is in the backend visible called SEO.

3. Update the database

You need to update the database in install tool afterwards. We will automatically insert the following SQL.

CREATE TABLE tx_myext_domain_model_mymod (
        tx_csseo int(11) DEFAULT '0' NOT NULL
