TYPO3 8 中显示当前页面的类别名称

Question

我正在尝试在 TYPO3 8 安装中显示当前页面的类别名称。在 TYPO3 7 中，它曾经像这样工作（见下文），但现在我只收到一个随机错误代码，没有文本输出。有什么想法吗？

lib.catclass = CONTENT
lib.catclass {

wrap = <div class="categories">|</div>

table = sys_category
select {
  pidInList = 35 // UiD of your category_page
  join = sys_category_record_mm ON(sys_category_record_mm.uid_local=sys_category.uid)
  where = sys_category_record_mm.tablenames='pages'
  andWhere.dataWrap = sys_category_record_mm.uid_foreign = {TSFE:id}
}

renderObj = TEXT
renderObj.field = title
renderObj.wrap = <li class="category {field:title}">|</li>
renderObj.insertData = 1

}

对应的错误输出如下：

    An exception occurred while executing 'SELECT * FROM `sys_category` INNER JOIN `sys_category_record_mm`
    `ON(sys_category_record_mm`.`uid_local=sys_category`.`uid)` ON WHERE 
    (`sys_category`.`pid` IN (35)) AND 
    (sys_category_record_mm.tablenames='pages') AND (`sys_category`.`sys_language_uid` IN (0, -1)) AND 
((`sys_category`.`deleted` = 0) AND (`sys_category`.`t3ver_state` <= 0) AND (`sys_category`.`pid` <> -1) AND (`sys_category`.`hidden` = 0) AND (`sys_category`.`starttime` <= 1546204860) AND
 ((`sys_category`.`endtime` = 0) OR (`sys_category`.`endtime` > 1546204860)))': You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version

尝试在 ON 之后添加一个 space，因此：

join = sys_category_record_mm ON (sys_category_record_mm.uid_local=sys_category.uid)

此外，andWhere 自 TYPO3 7.1 以来已被弃用，并已在 8 中删除。您需要将其添加到 where 并使用 markers 添加页面 uid。从我的头顶来看，那就是：

lib.catclass = CONTENT
lib.catclass {
  wrap = <div class="categories">|</div>

  table = sys_category
  select {
    pidInList = 35 // UiD of your category_page
    join = sys_category_record_mm ON (sys_category_record_mm.uid_local=sys_category.uid)
    where = sys_category_record_mm.tablenames='pages' AND sys_category_record_mm.uid_foreign = ###pageuid###
    markers {
      pageuid.data = TSFE:id
    }
  }

  renderObj = TEXT
  renderObj.field = title
  renderObj.wrap = <li class="category {field:title}">|</li>
  renderObj.insertData = 1
}
