我尝试使用Zend Framework 2创建一个简单的应用程序，现在堆叠在添加注释表单的位置。
我有两个模块＆＃34; Book＆＃34;和＆＃34;评论＆＃34;。我想显示一个表单，用于添加在模块中放置的注释＆＃34; Comment＆＃34;来自＆＃34; Books＆＃34;模块控制器。
当我尝试打开表单标记时出现问题。
我有这个错误：＆＃34;致命错误：调用未定义的方法Comment \ Form \ CommentForm :: openTag（）＆＃34; 。
我尝试检查$ this-＆gt; addComment - 使用var_dump，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>

答案 0 :(得分：1)
openTag()是来自表单视图助手的方法，而不是来自助手的方法。在您的视图脚本中，将此行print $this->addComment()->openTag($this->addComment);更改为此print $this->form()->openTag($this->addComment);
