Question

wanna check my uploaded images for right mime type:

 $user->image = CUploadedFile::getInstance($user, 'image');

in my Validation i check mime type with:

print_r(CFileHelper::getMimeType($this->image));

well, i uploaded a pdf and mime type was application/pdf.
i renamed the pdf to test.jpg, and mime type is now image/jpg which is a problem. i just wanna accept images.

i use the newest versions:
yii-1.1.12.b600af; XAMPP Windows 1.8.0; PHP Version 5.4.4

Answer 1

Because Yii by default defines mime type according to extension.

You can see the code

public static function getMimeType($file,$magicFile=null,$checkExtension=true){//code}

As you see $checkExtension=true.

You can try like that:

print_r(CFileHelper::getMimeType($this->image, null, false));

So It will not decide by extension.

For validation purpose:

class Item extends CActiveRecord
{
    public $image;

    public function rules()
    {
        return array(
            array('image', 'file', 'mimeTypes'=>'image/gif, image/jpeg'),
        );
    }
}

Alway use existing things, do not try to re-create.
