Question

我使用项目表构建扩展，这些扩展可以是项目或对象，项目是多个对象的容器。

为了区分，使用复选框将项目标记为项目，勾选此复选框时，将显示可选字段。该字段是项目与其包含的对象（相同表）之间的关系（m：n）。多个并排选择仅显示尚未通过foreign_table_where分配给项目的非项目和对象。

此字段具有以下TCA：

'objects' => [
  'displayCond' => 'FIELD:isproject:=:1',
  'exclude' => 0,
  'label' => $ll . 'tx_myext_domain_model_item.objects',
  'config' => [
    'type' => 'select',
    'renderType' => 'selectMultipleSideBySide',
    'foreign_table' => 'tx_myext_domain_model_item',
    'foreign_table_where' => 'AND isproject = 0 AND tx_myext_domain_model_item.uid NOT IN (SELECT uid_foreign FROM tx_myext_item_object_mm WHERE uid_local != ###THIS_UID###)',
    'MM' => 'tx_myext_item_object_mm',
    'size' => 10,
    'autoSizeMax' => 30,
    'maxitems' => 9999,
    'multiple' => 0
  ],
],

使用我的插件我提供选项（通过flexform）来选择仅显示对象，仅显示项目或两者，使用存储库中的以下代码完成：

public function findList($entryInclude = 'objects_only') {

 /** @var \TYPO3\CMS\Extbase\Persistence\Generic\Query $query */
 $query = $this->createQuery();

 switch ($entryInclude) {
   case 'projects_objects':
     $foreign_uids = $this->createQuery()
       ->statement('SELECT uid_foreign FROM tx_myext_item_object_mm')
       ->execute();
     $constraints = [
       $query->equals('isproject', 1),
       $query->logicalNot($query->in('uid', $foreign_uids))
     ];
     break;
   case 'projects_only':
     $constraints = $query->equals('isproject', 1);
     break;
   default:
     $constraints = $query->equals('isproject', 0);
     break;
 }

 $query->matching($query->logicalAnd($constraints));

 return $query->execute();
}

构建uid_foreign表中找到的所有tx_myext_item_object_mm数组的工作会导致错误......

在我看来，这是一个自定义查询的案例。以下内容应该为您提供mm-table中未引用的对象：
