This rectified that issue. =)

Cheers!

I’m trying to implement your code in my theme’s function page, but it doesn’t seem to do what I was hoping for – namely, change the permalink for a post IF a custom field called ‘postURL’ exists. I think that’s what you were trying to explain to @Sumesh, but somehow I don’t understand to how implement what you’ve described as:

post->ID, ‘url’, true);
if($url) { // if URL custom field exists, use that URL: ?>

Our code cleaner-upper doesn’t seem to be working with comments. Basically inside this if() statement you echo $url for the link, and after } else { it just links to the regular permalink.

What would the full code look like including this addition?

As it is now the title links to the source, but there’s no way for the reader to jump to the respective article on my site, when consumed in an RSS reader. So I guess visually something like this for the RSS article:

-TITLE (link to source)
-CONTENT
-PERMALINK

Where the permalink is either the word or a symbol. Believe Mr. Gruber has it set up this way. Hope this makes sense. I’d try to figure it out myself, but fear I’d totally destroy my site in the process.

Again, much thanks for sharing this information.

Under the line add_filter('the_permalink_rss', 'mp_permalink');, just add another filter to change the post’s permalink:

add_filter('post_link', 'mp_permalink');

However I wouldn’t recommend changing the actual permalink to your post. Then there’s no way to reference the post after it’s gone from your homepage. In the theme, instead of linking the posts’s title to its permalink, just link it to the custom field URL.

post->ID, 'url', true);
if($url) { // if URL custom field exists, use that URL: ?>

Our code cleaner-upper doesn’t seem to be working with comments. Basically inside this if() statement you echo $url for the link, and after } else { it just links to the regular permalink.

This would go in your theme’s file. Hopefully this helps. Let me know if anything isn’t clear.

On a side note, what would site visitors do? If you do not link to the source in post (and do it through custom field only), we need a hack to change the permalink for the posts too. I hope you’ll have a tutorial on that sometime later. Until then, I’m holding off deployment on my blog.
