php – Zend setElementsBelongTo()对子表单元素的影响

我在子表单($requestSubform)中有一个子表单($fileUploadSubform).我在父子窗体($requestSubform)上调用了setElementsBelongTo(“requestRow [$rowNumber]”).

$requestSubform= new Zend_Form_Subform();
    $requestSubform->setElementsBelongTo("requestRow[$rowNumber]");

    // add elements to $requestSubform

    // Now create the file upload subform
    $fileUploadSubform= new Zend_Form_SubForm();
    $fileUploadSubform->addElement('file','fileName')
            ->setLabel('File'); 

    $fileUploadSubform->addElement('text','fileDesc')
            ->setLabel('File Description'); 

    $requestSubform->addSubForm($fileUploadSubform,'fileUpload');

    $this->view->field = $requestSubform->__toString();

    // pass it as json via ajax back to javascript

当呈现表单时,$fileUploadSubform fileDesc元素的名称和id如下所示

name="requestRow[1][requestRow][1][fileUpload][fileDesc]"
id="requestRow-1-fileUpload-fileDesc"

为什么我在setElementsBelongTo()函数中设置的值重复两次？

先谢谢你！

作为临时解决方法,我刚从子子窗体($fileUploadSubform)而不是父子窗体($requestSubform)调用setElementsBelongTo()

我已经尝试了从http://zend-framework-community.634137.n4.nabble.com/Improved-array-support-for-Zend-Form-td667215.html获得的以下代码,因为它表示子表单元素正在正常工作.

$form = new Zend_Form();
    $form->setElementsBelongTo('foobar');

    $form->addElement('text','firstName')
    ->getElement('firstName')
    ->setLabel('First Name')
    ->setrequired(true);

    $form->addElement('text','lastName')
    ->getElement('lastName')
    ->setLabel('Last Name')
    ->setrequired(true);

    $subForm = new Zend_Form_SubForm();
    $subForm->setElementsBelongTo('foobar[baz]');
    $subForm->addElement('text','email')
    ->getElement('email')
    ->setLabel('Email Address');

    $subSubForm = new Zend_Form_SubForm();
    $subSubForm->setElementsBelongTo('foobar[baz][bat]');
    $subSubForm->addElement('checkBox','home')
    ->getElement('home')
    ->setLabel('Home address?');
    $subForm->addSubForm($subSubForm,'subSub');

    $form->addSubForm($subForm,'sub')
    ->addElement('submit','save',array('value' => 'submit'));
    print_r($form->__toString());

但是这是我得到的$subForm和$subFubForm的元素.

<input id="foobar-foobar-baz-email" type="text" value="" name="foobar[foobar][foobar][baz][email]">

<input id="foobar-foobar-baz-foobar-baz-bat-home" type="checkBox" value="1" name="foobar[foobar][foobar][baz][foobar][foobar][baz][foobar][baz][bat][home]">

我终于想出了这个问题.

这是这条线

$this->view->field = $additionalInfoSubform->__toString();

之前有一些元素没有显示,所以我补充说.只有现在我明白那些没有出现的元素是没有ViewHelper装饰器的元素.所以,当我将ViewHelper设置为装饰器,并删除上述字段并调用子表单的setElementsBelongTo(),而不必从该子表单的层次结构的根目录开始.

$form = new Zend_Form();
$form->setElementsBelongTo('foo');

$subForm = new Zend_Form_SubForm();
$subForm->setElementsBelongTo('bar');
$subForm->addElement('text','email')

$form->addSubForm($subForm,'sub');

name="foo[bar][email]"
