Question

我在使用ZF2在视图中呈现表单时遇到问题。我正在按照“Zend Framework 2.0 by Example”一书的说法。问题是，在对应视图中渲染表单时，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ZF论坛都遇到了所有类型的错误，但是我找不到我的问题的答案，所以我都选择了。

以下是相关文件：

// Module.php
namespace Users;

use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
use Zend\ModuleManager\Feature\ConfigProviderInterface;

class Module implements AutoloaderProviderInterface, ConfigProviderInterface {

    public function getAutoloaderConfig() {
        return [
            'Zend\Loader\ClassMapAutoloader' => [
                __DIR__ . '/autoload_classmap.php',

    }

    }

    <?php echo $this->form()->closeTag(); ?>

看起来视图的表单插件没有加载，但我不知道如何加载它或任何其他方式来超越这个问题。

Answer 1

编辑文件 modules.config.php ，可以在 config / 目录下找到并添加以下行：

'Zend\Form'

像这样：

return [
  'Zend\Form',
  'Zend\Db',
  'Zend\Router',
  'Zend\Validator',
  'Application',
];

Answer 2

修改 modules.config.php

实际路径（在我的项目中）/var/www/html/zf2-tutorial/config/modules.config.php

添加 Zend的\表”，在返回数组（）

我的档案看起来像这样

返回数组（

'Zend\Form',
'Zend\Router',
'Zend\Validator',
'Application',
'BookList'

）;

Answer 3

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>

它会显示你想要的东西。
