我有一个Zend表单，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'))))
));
此文件元素设置为以后的代码段中不需要。当我提交没有附加文件的表单时，表单validtion返回false，当我使用getErrors（）方法查找表单错误时，也没有报告错误。如果我提交带附件的表格，一切正常。
我一直在谷歌这个，但找不到答案。我希望有人可以解释为什么会这样，我正在使用ZF 1.11.11。
提前致谢。

以下是请求的更多代码示例。
这些是我用来验证表单的方法。我已将我用作验证错误的解决方法的代码标记为。
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。

我只能看到你的'count'验证器看起来有点不稳定，看起来你总是需要至少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'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'))),
以下是Zend_Validate_File_Count构造函数的API，请参阅ZF 1.11 API处的整个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，它是最大值 文件计数它还接受一个键为'min'和'max'的数组 $ options是一个整数，它将被用作最大文件数As Array 接受以下键：'min'：最小文件数'max'：最大值 filecount参数名称类型描述 $ options integer | array | \ Zend_Config适配器选项

仔细检查以确保
enctype='multipart/form-data'
包含在html表单元素中。我花了两个小时同样的问题。事实证明这是我的问题。
答案 2 :(得分：0)
RockyFord是正确的，您应该将min验证程序的Count值设置为0。
即使不需要元素，当值不为空时，仍会处理其验证器。文件元素与计数验证器的工作方式略有不同。如果指定min大于0，则仍需要上传许多文件。
请在关闭所需标志的位置尝试以下代码。另外，我们将Count验证器设置为至少需要0个文件。
$form->getElement('image')
->setRequired(false)
->getValidator('count')
->setMin(0);
我对此进行了测试并且有效。如果我没有将min设置为0，表单将无法验证，但是，我会看到一条错误消息，显示You must upload an image file。也许您的装饰器没有在File元素上显示错误？
答案 3 :(得分：0)
ZF 1.11 一个更简单的解决方案是在提交表单时删除元素：
$upload = new Zend_File_Transfer();
$files = $upload->getFileInfo();
if(empty($files))
{
$form->removeElement('image_name');
}
else
{
$form->image_name->receive();
}
if($form->isValid($_POST))
{
$formData = $form->getValues();
}

在类isValid派生的类中覆盖方法Zend_Form。
/**
* Class Custom_Form
*/
class Custom_Form extends Zend_Form
{
// [...]
/**
* Validate the form
*
* @param array $data
* @throws Zend_Form_Exception
* @return bool
*/
public function isValid($data)
{
/** @var Zend_Form_Element_File $file */
$file = $this->getElement('file');
/**
* Remember the validators we set before
*/
$validators = $file->getValidators();
/**
* Remove validators if field is empty
*/
if (empty($_FILES['file']['name'])) {
$file->removeValidator('Extension');
}
/**
* Run validation
*/
$isValid = parent::isValid($data);
/**
* Set back the original validators after validation

$file->setValidators($validators);
return $isValid;
