Hi @udapud
I can see from your code that the repeater field is called add_audio_file.
Why then do you have the code:
$attachment_id = get_field('add_audio_file');
This is not the attachment id, it is the repeater field array…
The attachment ID is found WITHIN the loop via:
$attachment_id = get_sub_field('add_audio_file_repeater');
But, now looking at your field names, I think you have them around the wrong way. Please read the documentation before coding and asking questions, it is very simple to understand. I think you have just copied / pasted without looking at the actual code.
Thanks
