Filter auto enclosure links before processing
|Reported by:||niallkennedy||Owned by:|
The do_enclose() function looks through post content for enclosure-worthy URLs, requests the URLs it finds, and stores in post meta.
I use sample code and dummy URLs in my posts: e.g. http://example.com/song.mp3. Right now do_enclose() finds the mention of the MP3, adds it to post meta, which later outputs in rss_enclosure() or atom_enclosure(). If I want to remove the enclosure from final markup I can attach to the added_postmeta action to remove a value after it was requested and inserted or act on the markup generated by rss_enclosure() or atom_enclosure() by emptying the string.
I would like to filter out the auto-discovered enclosure link before it is processed by WordPress, looked up in the database, and HEAD requested. If a filter existed on the parsed enclosure links I could remove links from dummy domains such as "example.com."
