Question

我有一个音频上传功能，可以上传用户选择的音乐。但是，有些文件显示格式正确，但上传者说我尝试上传的文件不正确。

我的CodeIgniter配置如下：

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

我使用以下内容来获取音频格式：

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

当我回显$ ext时，它显示mp3，但上传的返回时出现此错误：

不允许您尝试上传的文件类型。

当我使用音频转换器（我使用Freemake）将文件再次转换为mp3时，上传器允许该文件，所以我不确定该文件是否显示mp3，但仍然是文件系统上的旧格式。 / p>

非常感谢任何信息/帮助。

提前完成。

更新

我的PHP上传代码如下所示：

    $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);
    }

我的视图如下所示： 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();
                }
            },

                {

Answer 1

在codeigniter打开时，mimes.php 并加上这个。

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

application / octet-stream表示二进制流。带有MIME的附件内容类型“application / octet-stream”是二进制文件。通常，它将是必须打开的应用程序或文档在应用程序中，例如电子表格或文字处理器

PHP文件上传不允许使用allowed_types
