ZF 2.3 不同模块的显示形式

【中文标题】ZF 2.3 不同模块的显示形式【英文标题】：ZF 2.3 displaying form in different modules 【发布时间】：2015-02-01 14:52:49 【问题描述】：我正在尝试使用 Zend Framework 2 创建一个简单的应用程序，现在在添加 cmets 表单时进行堆叠。 我有两个模块“书”和“评论”。我想显示一个用于添加 cmets 的表单，该表单位于“Books”模块控制器的模块“Comment”中。 当我尝试打开表单标签时出现问题。 我遇到了这个错误：" 致命错误：调用未定义的方法 Comment\Form\CommentForm::openTag()"。 我尝试使用 var_dump 检查 $this->addComment - 一切看起来都很棒。 有人可以帮我解决这个问题吗？
<div class="row">
<div class="col-xs-12 commentBlock">
<?php
if($this->addComment)
$this->addComment->prepare();
$commentFieldset = $this->addComment->get('comment');
print $this->addComment()->openTag($this->addComment);
?>
</div>
</div>
这里是“评论”模块文件： Comment\Form\CommentFieldset

【问题讨论】：
【参考方案1】：openTag() 是来自表单视图助手的方法，而不是来自您的助手。在您的视图脚本中更改这一行：print $this->addComment()->openTag($this->addComment); 到这一行 print $this->form()->openTag($this->addComment);
