问题：Zend_Form_Element_File重命名文件保存扩展名

答案：

要在使用Zend_Form_Element_File上传文件时重命名文件并更改扩展名，您可以使用以下方法：

在表单中创建一个文件元素：

$fileElement = new Zend_Form_Element_File('file');
$fileElement->setLabel('Upload File')
            ->setDestination(APPLICATION_PATH . '/uploads')
            ->addValidator('Count', false, 1)
            ->addValidator('Size', false, 102400)
            ->addValidator('Extension', false, 'jpg,png,gif');

在表单提交时，使用事件监听器来重命名文件：

$form->addElement($fileElement);

$form->addElement(new Zend_Form_Element_Submit('submit'));

$form->submit->setLabel('Upload');

$form->addPrefixPath('My_Form_Element', 'My/Form/Element', 'element');
