i use the yii 1.1.14

It could be many things. First of all, check if your php.ini is configured properly:

1. max_file_uploads should be more or equal to the number of files you’re uploading.

2. upload_max_filesize should be enough to accept your file.

3. post_max_size should be more than upload_max_filesize since it will contain both upload and form data.

Thank you for your answer,every thing in my php.ini is correct, when the form is submitted, $files is empty and $model->attributes has one element and $_POST has 3 element, according to your code in the book, this is the result.

There were some changes in CFileValidator and CUploadedFile in recent versions which aren’t covered by the book. I guess it could be one of these:

CFileValidator now clears attribute after validation in case attribute is marked as safe in rules() which is default. The reason is that file uploads were often handled incorrectly by using real database attribute which lead to ability to write arbitrary data into database column.

If you’ve followed wiki article about uploading files, you need to mark attribute as unsafe:

public function rules()

{

    return array(

       array('image', 'file', 'types'=>'jpg, gif, png', 'safe' => false), // <--- here

    );

}

CUploadedFile::getInstancesByName() now cannot handle a single file upload. Either change your upload field name to be something like ImageUpload[] or, to keep backwards compatibility in your app, handle it like the following:

$this->ImageUpload = CUploadedFile::getInstancesByName('ImageUpload');

if (empty($this->ImageUpload)) {

    $this->ImageUpload = array(CUploadedFile::getInstanceByName('ImageUpload'));

}

Thank you again, but nothing changed, i don’t know what to do, i tested all of the cases that I knew, for two or more files, $files is empty.

In your code you have “file” not marked as “unsafe” as I’ve mentioned so you need to change rules() method to the following:

public function rules()

{

    return [

        ['file', 'file', 'types'=>'jpg', 'safe' => false],

    ];

}
