When designing the music page for my site iHipHopMusic.com, I had hit a road block. When users uploaded music to the site, I was using the update_post_meta function to pass the audio to a custom field so I could call the URL directly.
But for some reason I didn't want to stream my files from a custom field anymore, instead I wanted to call the the audio URL directly as an attachment the way you would with images attached to a pot.
I took to Google and I was surprised to find that it wasn't as easy to find as I thought it would be, after trolling for a few hours and asking some questions on a few boards I was able to peace together a working way of getting it done. It's works similar to calling image src of a featured image for a post.
Check out the code below.
It's quite a bit of code, more than I thought I would need for such a simple task, if you guys have a better method please suggest it below.
I'm still very much a noob when it comes to PHP, Web Designer by trade not a Programmer.
Thanks, hope this was helpful.
