上传文件上传

Question

我正在尝试使用uploadify，上传pdf或txt文件，但没有成功。 Uploadify 2.1.4只上传图片文件。我试图重命名文件扩展名，试图允许。，试图允许pdf或其他格式，但Uploadify上传只是F ****** g图像，我不知道为什么...

请帮我。

我使用这些设置：

public function show()
{
        if(!$this->dir) throw new exception("Upload dir is not set");
        if(!$this->url) throw new exception("Upload url is not set");

        $rem=(isset($_POST[$this->name."-rem"]))?$_POST[$this->name."-rem"]:"";
        $tpl='<div id="'.$this->name.'-queue" class="upload-queue">'.$this->fillQueue().'</div>';
        $tpl.='<input id="'.$this->name.'-uploadify" name="'.$this->name.'-uploadify" type="file" />';
        $tpl.='<input id="'.$this->name.'-files" name="'.$this->name.'-files" type="hidden" />';
        $tpl.='<input id="'.$this->name.'-rem" name="'.$this->name.'-rem" type="hidden" value="'.$rem.'"/>';
        //$tpl.='<link rel="stylesheet" type="text/css" href="/uploadify/uploadify.css" />';
        $tpl.="<script type=\"text/javascript\"><!--
        var ".$this->name."Files=".$this->currentCount.";
        function ".$this->name."DeleteFile(where)
        {
            var rem=$('#".$this->name."-rem').val();
            if(rem!='') rem+=',';
            $('#".$this->name."-rem').val(rem+$(where).parent().attr('id'));
            $(where).parent().remove();
            ".$this->name."Files--;
            if(".$this->name."Files<".$this->count.") $(\"#".$this->name."-uploadifyUploader\").show();
        }
        $(document).ready(function() {
        $(\"#".$this->name."-uploadify\").uploadify({
            'uploader'       : '/uploadify/uploadify.swf',

var settingObject = {
    'uploader'  : '/uploadify/uploadify.swf',   // set your path
    'checkScript':'/uploadify/check.php',    // set your path
    'script'    : '/uploadify/uploadify.php',   // set your path
    'cancelImg' : '/uploadify/cancel.png',   // set your path
    'folder'    : '/files/useruploads',
    'auto'      : true,
    'fileExt'   : '*.jpg;*.gif;*.png;*.txt;*.pdf;*.doc;*.docx',   // any extension you want to allow
    'fileDesc'  : 'Upload Files (.JPG, .GIF, .PNG, .TXT, .PDF, .DOC, .DOCX)',
    'removeCompleted': false
  };

$("#file-1").uploadify(settingObject);

参考:(文件扩展名）http://www.uploadify.com/documentation/options/fileext/

这对你有用..

Answer 2

每个文件可能存在大小限制问题。尝试添加以下内容

'sizeLimit': 500000

Answer 3

尝试在你的upload_max_filesize中编辑php.ini

Answer 4

将您当前的选项更改为：

$('#file_upload').uploadify({
    'uploader'    : '/uploadify/uploadify.swf',
    'script'      : '/uploadify/uploadify.php',
    'cancelImg'   : '/uploadify/cancel.png',
    'folder'      : '/uploads',
    'fileTypeExt'     : '*.jpg;*.gif;*.png',  <== this line
    'fileTypeDesc'    : 'Image Files'
});

供参考：http://www.uploadify.com/documentation/uploadify/filetypeexts/

Answer 5

改变这些行：

'fileTypeExt'        : '*.txt;*.pdf;',
'fileTypeDesc'       : '*.txt and *.pdf',

Answer 6

使用'fileExt' : '*.pdf;*.jpg;*.jpeg;*.png',而不是读取它的文件名。
