我在使用 ZF2 渲染视图中的表单时遇到问题。我正在关注"Zend Framework 2.0 by Example"一书。问题是，在相应的视图中呈现表单时，会弹出以下错误：
A plugin by the name "form" was not found in the plugin manager Zend'View'HelperPluginManager
我在这里和采埃孚论坛上都遇到了所有类型的错误，但我找不到问题的答案，所以我没有选择。

视图的表单插件似乎没有加载，但我不知道如何加载它或任何其他方法来克服这个问题。
编辑文件 modules.config.php可以在 config/ 目录下找到并添加以下行：
'Zend'Form'
喜欢这个：
return [
'Zend'Form',
'Zend'Db',
'Zend'Router',
'Zend'Validator',
'Application',
];
Edit modules.config.php
实际路径（在我的项目中）/var/www/html/zf2-tutorial/config/modules.config.php
加Zend''Form'， 在返回数组（)
我的文件如下所示
返回数组（
'Zend'Form',
'Zend'Router',
'Zend'Validator',
'Application',
'BookList'
）;
Viewhelper 需要更新以下内容：
$formHelper = new Zend'Form'View'Helper'Form();
$labelHelper = new Zend'Form'View'Helper'FormLabel();
$elementHelper = new Zend'Form'View'Helper'FormElement();
$inputHelper = new Zend'Form'View'Helper'FormInput();
$textareaHelper = new Zend'Form'View'Helper'FormTextarea();
$errorHelper = new Zend'Form'View'Helper'FormElementErrors();
echo $formHelper->openTag($form);
?>
<dl class="zend_form">
<dt><?php
$name = $form->get('name');
echo $labelHelper->openTag($name) . $name->getLabel();
echo $labelHelper->closeTag($name);
?>
</dt>
<dd><?php
echo $inputHelper($name);
echo $errorHelper($name);
?></dd>
它将显示您想要的内容。
