Typoscript: sys_categories der Seite auslesen.

UID der sys_category auslesen

Seit TYPO3 8 LTS hat sich scheinbar etwas geändert. Meine bisherigen Scripte zum Auslesen der sys_categories funktionieren nicht mehr. Nun habe ich ein neues:

 

lib {
    categories = CONTENT
    categories {
        table = sys_category
        select {
            pidInList = 1
            selectFields = description
            join = sys_category_record_mm ON sys_category_record_mm.uid_local = sys_category.uid
            where.data =field:recordUid
            where.intval = 1
            where.wrap = uid_foreign=|
        }
        renderObj = COA
        renderObj {
            1 = TEXT
            1.field = description
        }
    }
}

 

Der Wert für die „where“-Abfrage kommt aus dem Fluid über den data-Parameter:  

 

<f:cObject typoscriptObjectPath=„lib.categories“ data=„{recordUid: data.uid}“ />
{f:cObject(typoscriptObjectPath: 'lib.categories', data:'{recordUid: data.uid}')}

 

ACHTUNG: Das Ganze funktioniert nur, wenn die Kategorien auf der Root-Seite liegen. Ich hoffe, dass sich das in Version 9 ändert.

Category UID: Alle Informationen der Kategorie abrufen

Der oben beschrieben Weg gibt die ID der Kategorie aus. Möchte man aber Informationen wie Beschreibung oder Titel kommt man so nicht weiter. Hierzu habe ich eine Viewhelper-Bastelanleitung gesfunden:

Viewhelper:

    public function render($uid = null, $byParentId = false) {
        $queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable('sys_category');
        $query = $queryBuilder
            ->select('*')
            ->from('sys_category');

        if ($uid !== null) {
            $uid = is_array($uid) ? $uid : [$uid];

            $query->where(
                $queryBuilder->expr()->in(
                    $byParentId ? 'parent' : 'uid',
                    $uid
                )
            );
        }

        $result = $query->execute();
        $res = [];
        while ($row = $result->fetch()) {
            $res[] = $row;
        }

        $this->templateVariableContainer->add('sysCategoryDetailArray', $res);
    }

}

 

Dataprocessing Angaben im SETUP:

 

lib.contentElement.dataProcessing {
   999 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
   999 {
      if.isTrue.field = categories
      table = sys_category
      selectFields = sys_category.*
      pidInList = this
      recursive = 999
      join = sys_category_record_mm ON sys_category.uid = sys_category_record_mm.uid_local
      where.data = field:uid
      where.wrap = sys_category_record_mm.tablenames = 'tt_content' and sys_category_record_mm.uid_foreign='|'
      orderBy = sys_category.sorting
      as = categories
   }
}

 

Im Fluid wird es dann so verwendet. Der Viehelper verwendet die lib.category von oben. Achtung: Ihr müsst im RenderObj den Wrap entfernen. Nun kommt ein Array heraus, dass Ihr verwenden könnt:

 

<fh:SysCategory uid=„{f:cObject(typoscriptObjectPath:'lib.categories', data:{recordUid: data.uid})}“ />
<div class=„logo {sysCategoryDetailArray.0.description}“></div>
