我有一个Zend Form，其中包含一个文件元素。
$this->addElement('file', 'image', array(
'label' => 'Upload Image:',
'destination' => APPLICATION_PATH . '/tmp/',
'validators' => array(
array('count', true, array(
'min' => 1,
'max' => 1,
'messages' => array(
Zend_Validate_File_Count::TOO_FEW =>
'You must upload an image file',
Zend_Validate_File_Count::TOO_MANY =>
'You can only upload one image file'))),
array('extension', true, array(
'extention' => 'jpg,png,gif',
'messages' => array(
Zend_Validate_File_Extension::NOT_FOUND =>
'The file has an invalid extention (jpg,png,gif only)',
Zend_Validate_File_Extension::FALSE_EXTENSION =>
'The file has an invalid extention (jpg,png,gif only)'))),
array('imageSize', true, array(
'minheight' => self::IMAGEHEIGHT,
'minwidth' => self::IMAGEWIDTH,
'maxheight' => self::IMAGEHEIGHT,
'maxwidth' => self::IMAGEWIDTH,
'messages' => array(
Zend_Validate_File_ImageSize::HEIGHT_TOO_BIG =>
'The image must be exactly ' . self::IMAGEHEIGHT . ' pixels tall',
Zend_Validate_File_ImageSize::HEIGHT_TOO_SMALL =>
'The image must be exactly ' . self::IMAGEHEIGHT . ' pixels tall',
Zend_Validate_File_ImageSize::WIDTH_TOO_BIG =>
'The image must be exactly ' . self::IMAGEWIDTH . ' pixels wide',
Zend_Validate_File_ImageSize::WIDTH_TOO_SMALL =>
'The image must be exactly ' . self::IMAGEWIDTH . ' pixels wide',
Zend_Validate_File_ImageSize::NOT_DETECTED =>
'The image dimensions cannot be detected',
Zend_Validate_File_ImageSize::NOT_READABLE =>
'The image dimensions cannot be read'))))
));
在以后的代码中，此文件元素设置为不需要。当我提交不带文件的表单时，表单验证将返回false，同样，当我使用getErrors（）方法查找表单错误时，也不会报告任何错误。如果我提交带有附件的表格，则一切正常。
我已经在Google上搜索了一段时间，但找不到答案。我希望有人可以阐明为什么会发生这种情况，我正在使用ZF 1.11.11。
提前致谢。

以下是根据要求提供的更多代码示例。
这些是我用来验证表格的方法。我已经标记了用作验证错误解决方法的代码。
public function formValid(Array $params)
{
if (is_null($this->_form))
throw new Zend_Exception('You must first initialize the form');
$formValid = $this->_validateForm($this->_form, $params);
// Workaround for bug in validating file elements
if (!$formValid) {
if (!$this->_form->getMessages()) {
$formValid = true;
$this->_validValues = $this->_form->getValidValues($params);
}
}
if ($formValid) {
if ($this->_form instanceof Admin_Form_AddDirectSite ||
$this->_form instanceof Admin_Form_EditDirectSite) {
if (isset($this->_validValues['replaceImage'])) {
return $this->_form->getElement('image')->receive();
} else {
return true;
}
} elseif ($this->_form instanceof Admin_Form_PromoteDirectSite) {
$today = new Zend_Date();
$expires = new zend_date($this->_validValues['DirectSitesHighlighted']['toDate']);
if ($expires->isEarlier($today)) {
$this->_form->getSubForm('DirectSitesHighlighted')
->getElement('toDate')
->addError('The date must be in the future');
return false;
} else {
return true;
}
} else {
return true;
}
} else {
return false;
}
}
protected function _validateForm(Zend_Form $form, Array $params)
{
if ($form->isValid($params)) {
$this->_validValues = $form->getValidValues($params);
return true;
} else {
$this->_validValues = null;
return false;
}
}
这些是我用来初始化表单的函数，有两个表单类共享一个抽象类。
public function initAddForm()
{
$this->_form = new Admin_Form_AddDirectSite();
return $this;
}
public function initEditForm()
{
$this->_form = new Admin_Form_EditDirectSite();
return $this;
}
这些是三个表单类。

{
parent::init();
$this->setAction('/admin/direct-sites/add');
$this->setDecorators(array(
array('ViewScript', array('viewScript' => 'forms/addDirectSites.phtml'))
));
$this->getElement('image')->setRequired(true);
$this->addElement('hidden', 'replaceImage', array(
'required' => true,
'label' => 'Replace Image:',
'value' => 1,
'filters' => array('Int'),
));
}
}
class Admin_Form_EditDirectSite extends Admin_Form_DirectSites_Abstract
{

我所看到的是，您的'count'验证器看起来有点奇怪，看起来您始终需要至少 1 个文件。至于为什么没有错误信息，我不知道。
可以尝试设置一下'min' => 0
array('count', true, array(
'min' => 1,
'max' => 1,
'messages' => array(
Zend_Validate_File_Count::TOO_FEW =>
'You must upload an image file',
Zend_Validate_File_Count::TOO_MANY =>
'You can only upload one image file'))),
下面是 Zend_Validate_File_Count 构造函数的 API，请参阅ZF 1.11 API中的完整 API
__construct(integer|array|\Zend_Config $options ) : void 设置验证器选项
Min 限制文件计数，当与 max=null 一起使用时，它是最大文件计数 它也接受带有键 'min' 和 'max' 的数组 如果 $options 是整数，它将用作最大文件计数 As Array接受以下键： 'min'：最小文件计数 'max'：最大文件计数 参数 名称 类型 描述 $options integer|array|\Zend_Config 适配器的选项
