hello

1. I don't understand.. you already have the file and the code you need... just put it there and it will work.

2. well that requires a bit more coding.. we can do it through our Custom Coding Service if you're interested.

1. I'm newbie in PHP. I understand, what I must replace this code (58-67), but I don't know how. I need to disable the ability to select artists.
2. What are conditions of your Custom Coding Service?

Hello.
1. I don't understand meaning of this term (62):

if($row->id == $this->album->artist_id)

I replace it so:

if($row->artist_name == $this->album->artist_id)

And I add 'disabled' attribut for 'select' form.

The name of current user display only now. As I wanted.

2. What are conditions of your Custom Coding Service?

Hello
If I want a user to upload his mp3-files in his folder ( / ),
I must to modify \components\com_muscol\helpers\helpers.php (397): static function create_file_link($song) and $dirname or $file_link?

Do I understand right?

Hello!

1. No.. this replacement you put makes no sense, it won't serve you.

2. For Custom Coding Service, please contact us directly at support@ joomlathat.com. You can email us your requirements and we can make a quote for you.

3. No... that's not the file to modify, this only "gives back" the link, it does not create anything...

1. No.. this replacement you put makes no sense, it won't serve you.

However, before the replacement the condition didn`t work, and after the replacement - worked. But I don`t understand the meaning of the condition.

1. No.. this replacement you put makes no sense, it won't serve you.

yes, you're right.
I modify this code:

if($row->artist_name == JFactory::getUser()->name) $selected = "selected" ;?>

And it worked correctly.
