CodeIgniter：不允许您尝试上传的文件类型。 isset($this->_mimes[$ext]) 总是空的
CodeIgniter: The filetype you are attempting to upload is not allowed. isset($this->_mimes[$ext]) is always null
我已经为这个问题花了几个小时，但我不知道如何解决它。我在尝试上传图片时收到一条错误消息。错误信息是 "The filetype you are attempting to upload is not allowed." 但我不认为文件类型导致了这个问题。我发现 ! $this->upload->do_upload('image') 总是错误的。我发现这是因为 $this->_mimes[$ext])（在 "system/libraries/Upload.php" 文件中。）总是给我带来 NULL。
当我测试我的功能时，我尝试 var_dump($this->file_type); 并得到 "image/jpeg"。
我也试过 var_dump($ext); 得到了 "jpg"。
这是 Image.php 文件的一部分。
<?php echo form_open_multipart('/image/index');?>
<fieldset>
<legend>Upload Image</legend>
<div><label>File: </label><input id="image" type="file" name="image" /></div>
<div><label>Title: </label><input id="title" type="text" name="title" /></div>
<div class="error">
<?php echo $error; ?>
</div>
</fieldset>
<div class="form_line"><input id="image_submit" type="submit" value="Upload Picture" class="submit" /></div>
</form>
这是 Picture.php 文件的一部分。
function index()

$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = 40960000;
$config['max_width'] = 0;
$config['max_height'] = 0;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('image'))
{
$page_data = array('files' => $file_send, 'error' => $this->upload->display_errors());
$this->load->view('media/image_upload', $page_data);
}
else {...}
}
这是我找到空值的地方。这是 CodeIgniter 代码。
public function is_allowed_filetype($ignore_mime = FALSE)
{
if ($this->allowed_types === '*')
{
return TRUE;
}
if (empty($this->allowed_types) OR ! is_array($this->allowed_types))
{
$this->set_error('upload_no_file_types', 'debug');
return FALSE;
}
$ext = strtolower(ltrim($this->file_ext, '.'));
if ( ! in_array($ext, $this->allowed_types, TRUE))
{
return FALSE;
}
// Images get some additional checks
if (in_array($ext, array('gif', 'jpg', 'jpeg', 'jpe', 'png'), TRUE) && @getimagesize($this->file_temp) === FALSE)

我想通了。这是因为 mimes.php 文件。以前，CodeIgniter 提供 mimes.php 这种格式。 $mimes = array( 'hqx' => 'application/mac-binhex40',...。但是，当前的 CodeIgniter 将格式更改为 return array(
'hqx' => array('application/mac-binhex40', ...。当我更新框架时，我没有更新 mimes.php 文件。非常感谢 Alex 给我提示！
修改后的mimes.php.

我想通了。这是因为 mimes.php 文件。以前，CodeIgniter 提供 mimes.php 这种格式。 $mimes = array( 'hqx' => 'application/mac-binhex40',...。但是，当前的 CodeIgniter 将格式更改为 return array(
'hqx' => array('application/mac-binhex40', ...。当我更新框架时，我没有更新 mimes.php 文件。非常感谢 Alex 给我提示！
修改后的mimes.php.
