This is probably the case because if the post is the first post in the
list of posts that are displayed on the home page, it also sets the
$post variable to that first post. What you could do is either post a
new entry (lame solution, but will probably work) or add an if()
statement that checks if you've requested that page specifically:
if($theme->request->display_entry) { /* show the link */ }
I was also thinking about a more generic solution. Here's what I would
do for that, although it's probably much more than one might want to
undertake if just thinking of a one-off solution:
Create a plugin that adds the jetpack link tag to any post that includes
post info for a jetpack plugin.
This will give your solution a bit more flexibility, since you'll be
able to add a jetpack extension to any post you want. You'd do this by
adding a field (from your plugin) to the post publishing page. Save
this field in the post info table, like this:
$post->info->jetpack = 'whatever';
And then provide that same theme_header() function you mentioned, but
from your theme, and have it check for the requisite post info in the
post. Something like:
public function theme_header($theme) {
if(isset($theme->post) && isset($theme->post->info->jetpack)) {
return '<link rel="jetpack" href="' .
$theme->post->info->jetpack .
. '">';
}
}
For hints on how to accomplish the parts I didn't describe, look at some
of the other plugins in the extras repo that add fields to the publish
page, and how they save their data. If you're so-inclined.
