phpthumb zend框架

Question

我可以上传图片并使用phpthumb调整大小,但我怎样才能上传原始图片？

     if ($this->getRequest()->isPost()) {
        $formData = $this->getRequest()->getPost();
            if ($form->isValid($formData)) {

            // upload the image
            if ($form->station_image->isUploaded()) {
                $form->station_image->receive();
                $station_image = '/upload/images/radio/' . basename($form->station_image->getFileName());
                //upload thumb
                include_once '../library/PhpThumb/ThumbLib.inc.php'; 
                    $thumb = PhpThumbFactory::create($form->station_image->getFileName());                                    
                    $thumb->resize(50, 50)->save($form->station_image->getFileName()); 
                  //thumb ends



            }else{
                echo 'cannot upload'. exit;
            }

我的表格看起来像这样

$station_image->setLabel('Upload File: ')
                        ->setDestination(APPLICATION_PATH.'/../public/upload/images/radio')
                        ->addValidator('Extension', false, 'jpg,png,gif')
                        ->addValidator('Size', false, 902400)
                        ->addValidator('Count', false, 1)
                        ->setRequired(false);

请帮我如何上传多个缩略图或如何上传原始文件？谢谢

您正在将原始图像传递给PHPThumb的构造函数:

$thumb = PhpThumbFactory::create($form->station_image->getFileName());

$form->station_image->getFileName()原始文件也是如此.问题是您使用调整大小的文件名覆盖原始文件名,请尝试以下操作:

$thumb = PhpThumbFactory::create($form->station_image->getFileName());                                    
$thumb->resize(50, 50)->save('/path/where/you/want/resized/image/to/go.png');

尝试一下:

if ($form->station_image->isUploaded()) {

    $form->station_image->receive();
    $station_image = '/upload/images/radio/' . basename($form->station_image->getFileName());
    //upload thumb
    include_once '../library/PhpThumb/ThumbLib.inc.php'; 
    $thumb = PhpThumbFactory::create($form->station_image->getFileName());

    // Notice this is using $station_image, which I assume is an accessible path
    // by your webserver                                    
    $thumb->resize(50, 50)->save($station_image); 
    //thumb ends

 }else{

尝试改变这个:

 $station_image = '/upload/images/radio/' . basename($form->station_image->getFileName());

对此:

 $station_image = '/upload/images/radio/thumb_' . basename($form->station_image->getFileName());
