Why does this pibase extension not get loaded?

Question

i'm updating a project from TYPO3

• 6.x to 7.x
• 7.x to 8.7

im already on 8.7 and now working on the extensions. we have a pibase extension were the support should be still available in 8.7

i've refactored a few things already:

• i replaced the old classes with the new namespaces based on the ClassAliasMap.php
• i've adapted the new TCA approach with Configuration/TCA/Overrides
• changed from $TCA to $GLOBALS['TCA']

another task will be to rework the templates from css_styled_content to fluid_styled_content. but i'm not right there because im stuck to get the plugin be available in Template>RootPage>Info/Modify>Edit-whole-template>Includes. its just not in the "available items" list.

i thought there are 2 steps do get this done

register the plugin for frontend rendering with

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPItoST43($_EXTKEY, 'pi1/class.tx_rxextkey_pi1.php', '_pi1', 'list_type', FALSE);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPItoST43($_EXTKEY, 'pi2/class.tx_rxextkey_pi2.php', '_pi1', 'list_type', FALSE);

and make the plugin selectable in the backend with

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPlugin(
array('LLL:EXT:rx_extkey/Resources/Private/Language/locallang_db.xml:tt_content.list_type_pi1',
     'rx_extkey_pi1',
     \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath('rx_extkey') . 'ext_icon.png'
     ),
     'list_type',
     'rx_extkey'
    );

heres how the extension/plugin is structured generally:

myextension
- configuration/
  - TCA/
   - Overrides/
     tt_content.php
- doc/
  wizard_form.dat
  wizard_form.html
- eId/
  classX.php
  classO.php
  classL.php
- pi1/
  class.tx_myextension_pi1.php
  flexform_ds.xml
  locallang.xml
- pi2/
  class.tx_myextension_pi1.php
  flexform_ds.xml
  locallang.xml
- res/
  something.html
  somethingelse.html
ext_emconf.php
ext_icon.gif
ext_localconf.php
ext_tables.php
locallang_db.xml

so inside the ext_localconf i call addPItoST43 from the ExtensionManagementUtility to actually add the class files

the emconf is just "default" so to speak and a description of the plugin

the file ext_tables.php is empty now because all the stuff from in there moved to the Configuration/ part

the parts i moved to tt_content.php inside the Configuration/ directory contain 2 TCA Overrides with $GLOBALS['TCA']['tt_content']['types'] and $GLOBALS['TCA']['tt_content']['columns'] followed by 3 addPlugin calls also from the ExtensionManagementUtility

so with all this done i still cant include the plugin within the root page to get the actual functionality - i have no idea how to further process to get this to work - any help is much appreciated, if any further information or code is needed just drop a comment

further investigation: so i have debugged like every part of the extension and the part for the backend seems to work just fine, i see the plugin content and can select pieces out of the database to theoretically display in the frontend. the only thing is that TYPO3 never comes into my class tx_extkey_pi1 to actually fill the template with content - i have var_dumps() with exit() in both main() and renderTemplate() but they get never triggered.

Answer 1

Ich think this part

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPlugin(
array('LLL:EXT:rx_extkey/Resources/Private/Language/locallang_db.xml:tt_content.list_type_pi1',
     'rx_extkey_pi1',
     \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath('rx_extkey') . 'ext_icon.png'
     ),
     'list_type',
     'rx_extkey'
    );

belongs in ext_tables.php
