CodeIgniter "The filetype you are attempting to upload is not allowed."
提问by Cyclone
I was searching a lot and found many questions regarding this problem, unfortunately none of answers did help me.
我搜索了很多，发现了很多关于这个问题的问题，不幸的是没有一个答案对我有帮助。
I'm trying to upload a png image, and I'm receiving the following error:
我正在尝试上传 png 图像，但收到以下错误：
The filetype you are attempting to upload is not allowed.
不允许您尝试上传的文件类型。
I was following this CI guide to build my code: http://codeigniter.com/user_guide/libraries/file_uploading.html
我按照这个 CI 指南来构建我的代码：http: //codeigniter.com/user_guide/libraries/file_uploading.html
Here is what I got:
这是我得到的：
view file:
查看文件：
[..]
<?= form_open_multipart() ?>
<input type="file" name="userfile" size="20" />
<br /><br />
<input type="submit" value="upload" />
<?= form_close() ?>
[..]
My controller:
我的控制器：
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$xx = array('upload_data' => $this->upload->data());
$mimetype= $xx['upload_data']['file_type'];
var_dump('Mime: ' . $mimetype);
var_dump($_FILES);
if ( !$this->upload->do_upload())
{
Notice::add($this->upload->display_errors(), 'error');
}
else
{
$data['upload_data'] = $this->upload->data();
}
As you can see I'm tryin to var_dumpthe mime type and result is empty.
如您所见，我正在尝试var_dump使用 mime 类型，结果为空。
When I do var_dump($_FILES)it looks like everything is fine:
当我这样做时var_dump($_FILES)，看起来一切都很好：
array(1) { ["userfile"]=> array(5) { ["name"]=> string(14) "imageofm.png" ["type"]=> string(9) "image/png" ["tmp_name"]=> string(18) "/var/tmp/php5cDAZJ" ["error"]=> int(0) ["size"]=> int(358) } }
Also, I got 'png' => array('image/png', 'image/x-png'),line, in my config/mimes.php.
另外，我'png' => array('image/png', 'image/x-png'),在我的config/mimes.php.
However, it does happend for all images (haven't tried yet other extensions).
但是，它确实发生在所有图像上（还没有尝试过其他扩展）。
I'd appreciate every help attempt.
我很感激每一次帮助尝试。

只需编辑application/config/mimes.php 中的mimes.php文件，并将csv的行替换为：

Actually, in my case, I created a blob object from a canvas by void canvas.toBlob(callback, mimeType, qualityArgument)method So the blob file does NOT have its real name (which has an extension), it's just only 'blob'. So I have to use the legacy way to upload the file, instead of an 'upload' library:
实际上，就我而言，我通过void canvas.toBlob(callback, mimeType, qualityArgument)方法从画布创建了一个 blob 对象，因此 blob 文件没有其真实名称（具有扩展名），它只是“blob”。所以我必须使用传统方式上传文件，而不是“上传”库：
move_uploaded_file ( $file["tmp_name"], $target_file )
