For some odd reason, I'm convinced that there exists a plugin that'll do what I'm after. But I've yet to find it in my links or with searches. Hopefully it's just a case of my search-fu being weak...
I'd like to be able to add a custom field to some posts.
Then, in the single.php I'd like to check for the field.
If the field exists (or has a value of "True"?) I'd like to display some additional code at the end of the content.
Does this ring any bells? Any ideas?
My first question would be to what would be the determiner of which posts? Certain category?
Not category. The determiner would be me remembering to add the custom field to the applicable posts.
Elaboration of original post: Long story short, I want to manually/periodically add a custom field to some of my more popular posts. If that field is set or of a certain value (aka "True") I want to add some code to the post.
What code? The new tagometer!
So, the idea is that I'd add a custom field to the applicable posts. Then, in single.php, I'd check for the tag and add code as necessary.

For my plugin posts (to display download and source view links) I currently test off $post_meta_cache, like so:
if( $post_meta_cache[$post->ID]['wp'] ) :
With 'wp' the key for the desired custom field. Your mileage may vary...
Ah, there we go. Don't need a plugin, just need a kick in the rear. Thanks guys!
Here's what I ended up with:
<?php if( $post_meta_cache[$post->ID]['ShowDtag'] ) { ?>
<script src="http://images.del.icio.us/static/js/blogbadge.js"></script>
<?php } ?>
ShowDtag is my custom field. Only exists on posts that I want to show the del.icio.us thingy on.
That little code snippet no longer works since I've upgraded to 2.1.
Can I not use $post_meta_cache[$post->ID]['ShowDtag'] in that fashion any more?

Use the API function get_post_meta($post_id, $key, $single = false)
e.g.
<?php if( get_post_meta($post->ID, 'ShowDtag', true) ) { ?>
<script src="http://images.del.icio.us/static/js/blogbadge.js"></script>
<?php } ?>
The third param just tells it that you're expecting a single result... otherwise you get an array of results.
Thank you, Mark. Will give that a shot soon. :-)
[Update] Worked great. Thanks!
