thanks.

to save uploaded image in selected folder: (keep in mind $image in both examples uploadform instance https://github.com/yiisoft/yii2/blob/master/docs/guide/input-file-upload.md)

    $image->file = uploadedfile::getinstance( $image, 'file' );      if ($image->file && $image->validate())     {     $tmp = '/anyfolder/' . array_pop( explode( '/', $image->file->tempname ) );     $user->image = $tmp;     $user->save();     $image->file->saveas( yii::getalias( '@webroot' ) . $tmp . '.' . $image->file->extension );      }

tempname helps save image unique name given system. code above saves relational path of $image in image( string keep address) field of $user.

now save uploaded image blob in database:

    $image->file = uploadedfile::getinstance( $image, 'file' );      if ($image->file)     {     $user->image_blob = file_get_contents( $image->file->tempname );     $user->save();      }
