zend-framework - 仅渲染 <form> 标签

Question

有什么方法可以只渲染开始<form> Zend_Form 对象的标签？

print $this->registerForm->renderForm();

渲染 <form></form> ，我只需要<form>

编辑:

在 Asleys 可能的解决方案之后，我为 My_Form 类编写了这个

public function renderFormOpen() {
    return str_replace('</form>', '', $this->renderForm());
}

public function renderFormClose() {
    return '</form>';
}

在查看 ZF 库中的代码之后，我仍然在寻找 ZF 的瘦身方式，尽管我认为没有任何方法。

您可以编写一个自定义表单装饰器，它使用仅呈现打开表单标签的自定义 View 助手。但我认为这有点矫枉过正。
只需“硬编码”表单标签并使用 View 中表单变量提供的数据填充属性。

<!--in your view-template -->
<form action="<?php echo $this->form->getAction() ?>"
      enctype="<?php echo $this->form->getEnctype() ?>"
      method="<?php echo $this->form->getMethod() ?>"
      id="<?php echo $this->form->getId() ?>"
      class="<?php echo $this->form->getAttrib('class') ?>" >

    <!--in case your products are represented as elements -->
    <?php foreach ($this->form->getElements() as $element): ?>
       <?php echo $element ?>
    <?php endforeach; ?>

    <!--in case your products are represented as displayGroups -->
    <?php foreach ($this->form->getDisplayGroups() as $displayGroup): ?>
       <?php echo $displayGroup ?>
    <?php endforeach; ?>

    <!--in case your products are represented as subforms -->
    <?php foreach ($this->form->getSubforms() as $subform): ?>
       <?php echo $subform ?>
    <?php endforeach; ?>

    <!--in case your products are rendered by a view helper -->
    <?php foreach ($this->products as $product): ?>
       <?php echo $this->renderProduct($product) ?>
    <?php endforeach; ?>
</form>

只是为了好玩，矫枉过正

// Get your products form
$form = new Form_Products();
// Add custom prefix path
$form->addPrefixPath('Foobar_Form_Decorator', 'Foobar/Form/Decorator', 'decorator');
// Set OnlyOpenTagForm-ViewHelper for FormDecorator
$form->getDecorator('Form')->setHelper('OnlyOpenTagForm');

// copy Zend/View/Helper/Form to Foobar/Form/Decorato/OnlyOpenTagForm.php
// In OnlyOpenTagForm.php
//   replace Zend_View_Helper_Form with Foobar_View_Helper_OnlyOpenTagForm
//   replace method "form" with onlyOpenTagForm"
//   replace
if (false !== $content) {
    $xhtml .= $content
           .  '</form>';
}
//   with:        
if (false !== $content) {
    $xhtml .= $content;
}

完成! - Java-Guys 会喜欢的 ;)
