PHP文件上傳不允許格式在allowed_types

Question

我有一個音頻上傳功能，可以上傳用戶選擇的音樂。 但是，有些文件顯示它們的格式正確，但上傳者說我試圖上傳的文件不正確。

我笨的配置如下：

$config['allowed_types'] = 'mp3|wav|m4a|wma'; 

我使用以下方法來獲取音頻格式：

$ext = end(explode(".", $_FILES["userfile"]["name"])); 

當我回聲$轉出，它顯示的MP3，但上傳帶有此錯誤的退貨：

The filetype you are attempting to upload is not allowed.

當我使用音頻轉換器（我使用Freemake）將fi再次mp3，上傳者允許該文件，所以我不知道該文件是否顯示MP3，但仍然是文件系統上的舊格式。

任何信息/幫助將不勝感激。

Thanx提前。

UPDATE

我的PHP上傳代碼如下所示：

$entry_num = $this -> input -> post('entry_num'); 
    $location = $this -> input -> post('location'); 

    $foldername = "./music/$location"; 

    if (!file_exists($foldername)) 
    { 
     mkdir($foldername, 0777, true); 
    } 

    $ext = end(explode(".", $_FILES["userfile"]["name"])); 

    $config['upload_path'] = $foldername.'/'; 
    $config['allowed_types'] = 'mp3|wav|m4a|wma'; 
    $config['file_name'] = $entry_num.'.'.$ext; 
    $config['overwrite'] = TRUE; 

    $this -> load -> library('upload', $config); 

    if (!$this -> upload -> do_upload('userfile')) 
    { 
     $errors = array('error' => $this -> upload -> display_errors()); 
     $return = implode(" ",$errors); 
    } 

我的視圖看起來是這樣的： HTML

 <div class="control-group" id="load-music"> 
      <label for="grouping_style" class="control-label">Load MP3 Music</label> 
      <div class="controls"> 
       <input type="file" name="userfile"> 
      </div> 
     </div> 

的JavaScript

(function() 
    { 
     var bar = $('.bar'); 
     var percent = $('.percent'); 
     var status = $('#status'); 
     var progressbar = $('#progressbar'); 

     $('#mp3form').ajaxForm({ 
      beforeSubmit : function(data) { 
       check = data[1].value; 
      }, 
      beforeSend: function() { 
       progressbar.show(); 
       status.empty(); 
       var percentVal = '0%'; 
       bar.width(percentVal) 
       percent.html(percentVal); 
      }, 
      uploadProgress: function(event, position, total, percentComplete) { 
       var percentVal = percentComplete + '%'; 
       bar.width(percentVal) 
       percent.html(percentVal); 

       if (percentComplete > 10) 
       { 
        percent.show(); 
       } 
      }, 
      complete: function(xhr) {        
       if (xhr.responseText == '"success"') 
       {          
        $('#modal-footer-content').html("<button class='btn btn-default' onclick='cancel()'>Close</button>"); 
        $('#modal-text').html('Music sucessfully uploaded, thank you.'); 

        //Insert code to update table row with music play back

雖然在codeigniter打開，mimes.php 並添加此。

'mp3' => array('audio/mpeg', 'audio/mpg', 'audio/mpeg3', 'audio/mp3', 'application/octet-stream') 

application/octet-stream means binary stream. A MIME attachment with the content type "application/octet-stream" is a binary file. Typically, it will be an application or a document that must be opened in an application, such as a spreadsheet or word processor
