Question

上传名称中包含空格的图像时会出现错误消息：

An unknown error has occurred.

这是表单的代码：

    $resizeRename = new Zend_Form_Element_File('renameResize');
    $resizeRename->setDestination('images/fbAppLogo');
    $resizeRename->setLabel('Upload App Logo');
    $resizeRename->addFilter(new Skoch_Filter_File_Resize(array(
        'width' => 111,
        'height' => 74,
        'keepRatio' => true,
    )));  
    $resizeRename->setAttrib('class','tooltip');
    $resizeRename->setAttrib('title','Upload file');   
    $this->addElement($resizeRename);

        here is the code of my controller:-
           if ($form->isValid($data)) {
                             $file=pathinfo($form->renameResize->getFileName());
                             if($form->renameResize->receive()) {
               $this->view->renameResize=pathinfo($form->renameResize->getFileName());
                             }
                       }

如果图像名称不包含空格，上述代码工作正常。
