ZF2表单集合 - 过滤空记录

Question

我正在尝试研究如何从表单集合中过滤空记录.在我的应用程序中,我有2个实体,Competition和League.比赛可能有零个或多个联赛.

所以我创建了一个竞赛表单(CompetitionForm),一个竞赛字段集(CompetitionFieldset)和一个联盟字段集(LeagueFieldset).

将CompetitionFieldset被添加到CompetitionForm和CompetitionFieldset用途Zend\Form\Element\Collection,以允许用户添加1个或多个联盟.我已经为下面的每个类添加了当前代码.

默认情况下,我想在比赛中显示3个联赛的输入字段,因此在CompetitionFieldset我添加Zend\Form\Element\Collection项目时,我将计数选项设置为3.

但如果用户没有为联盟提供任何数据,我想忽略它们.目前,我的数据库中创建了三个空的关联联盟.

如果我设置InputFilter上LeagueFieldset,使name例如必填字段,则表单不会验证.

我也许应该提一下,我正在使用Doctrine2来模拟我的实体并为我的表格补水等.

我敢肯定,我可以把它与一些额外的代码在我的模型在我的控制,我处理的形式工作,甚至,但我敢肯定,有可能使用的过滤器更为整洁的解决方案.

如果有人能指出我正确的方向,我将不胜感激.

非常感谢您提供的任何帮助.

        $fieldset = new CompetitionFieldset($objectManager);
        $fieldset->setUseAsBaseFieldset(true);
        $this->add($fieldset);

        $this->add(array(

在将请求传递给 EntityManager 之前，您需要从请求中获取数据，这是肯定的。只需添加您自己的验证即可过滤空记录。您还可以提供 javascript 过滤器，该过滤器将捕获提交表单事件并在提交之前删除空字段。
