忽略文件上传的空实例与Zend框架?文件因此无法上传

我试图在ZF1中上传几个文件

有两个上传选项;音频或图像。当我试图上传图像时，只有file_audio的空实例有问题。

这是我的print $_FILES

Array
(
    [image_file] => Array
        (
            [name] => boss.jpg
            [type] => image/jpeg
            [tmp_name] => C:'WINDOWS'Temp'phpA01.tmp
            [error] => 0
            [size] => 37246
            [options] => Array
                (
                    [ignoreNoFile] => 
                    [useByteString] => 1
                    [magicFile] => 
                    [detectInfos] => 1
                )
            [validated] => 
            [received] => 
            [filtered] => 
            [validators] => Array
                (
                    [0] => Zend_Validate_File_Upload
                )
        )
    [audio_file] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 
            [options] => Array
                (
                    [ignoreNoFile] => 
                    [useByteString] => 1
                    [magicFile] => 
                    [detectInfos] => 1
                )
            [validated] => 
            [received] => 
            [filtered] => 
            [validators] => Array
                (
                    [0] => Zend_Validate_File_Upload
                )
        )
)

这是我的Zend代码它只在两个文件都被选中的情况下工作

if (! empty ( $post ['type'] )) {
    $adapter = new Zend_File_Transfer ();
//  echo "<pre>"; print_r($_FILES);   "</pre>"; exit;
    if ($post ['type'] == 'Image' && ! empty ( $_FILES ['image_file'] ['name'] )) {
        $files = $adapter->getFileInfo();

        echo "<pre>"; print_r($files);   "</pre>"; exit;
        $files = $adapter->getFileInfo();
        $files_path = $config->topic_images->path; 
        // Limit the MIME type of all given files to gif and jpeg images
//      $adapter->addValidator ( 'MimeType', false, array ('image/jpeg', 'image/png', 'image/jpg' ) );
//      $adapter->addValidator ( 'Extension', false, 'png,jpeg,jpg' );
//      $adapter->addValidator ( 'FilesSize', false, array ('min' => '1kB', 'max' => '5MB' ) );
//      $adapter->addValidator ( 'ImageSize', false, array ('minwidth' => 0, 'maxwidth' => 800, 'minheight' => 0, 'maxheight' => 800 ) );
// Limit the size of a image to a height of 100-200 and a width of 40-80 pixel

    }elseif($post ['type'] == 'Audio' && ! empty ( $_FILES ['audio_file'] ['name'] )) {
        $files_path = $config->topic_audio->path;
    }elseif($post ['type'] == 'Video' && ! empty ( $post ['video_file'] )) {
    }

$files = $adapter->getFileInfo ();
$file_name = null;
$tmpArr = null;
$fname = null;
$fext = null;

        foreach ( $files['image_file'] as $file => $info ) {
    if (! empty ( $info ['name'] )) {
        $fname = substr ( $info ['name'], 0, strrpos ( $info ['name'], "." ) );
        $fext = substr ( $info ['name'], strrpos ( $info ['name'], "." ) );
    }
}

    if (! empty ( $fname )) {
    $file_name = $fname . "-" . $post ['topic_id'] . $fext;
    $horrible_chars = array ("~", "@", "#", "$", "%", "^", "&", "*", "(", ")", " " );
echo     $cleanfilename = str_replace ( $horrible_chars, "", $file_name );

    $adapter->setDestination ( $files_path );
//  $adapter->addFilter ( 'Rename', array ('target' => $files_path . DS . $cleanfilename, 'overwrite' => true ) );

    if ($adapter->receive ()) {
    //  echo "xxx"; exit;
        $post ['filename'] = $cleanfilename;
        $result = $TopicModel->updateTopicassociation ( $post );
        $old_file = $files_path . DS . $post ['existing_file'];
        if (file_exists ( $old_file )) {
            if ($file_name != $post ['existing_file']) {
                @unlink ( $old_file );
            }
        }
        $this->_flashMessenger->addMessage ( 'Topic '.$post['type'].'added successfully' );
    } else {

    $errors = $adapter->getErrors();
    print_r($errors); exit;
        $post ['filename'] = null;
        $res_delete = $TopicModel->updateTopicassociation ( $post ['topic_id'] );
        $this->_flashMessenger->addMessage ( 'Error(s) encountered. File Association not updated.' );
    }
}
//    else {
//      if (! empty ( $post ['chkDelete'] ) && $post ['chkDelete'] == 1) {
//          $post ['filename'] = null;
//          $result = $jobModel->updateJobLogo ( $post );
//          $old_file = $files_path . DS . $post ['c_image_name'];
//          
//          if (file_exists ( $old_file )) {
//              @unlink ( $old_file );
//          }
//      }
//    }
}

我花了一整天的时间试图上传一个图像或音频文件。有人知道是什么问题吗?
