Well, you could modify the query in
wp-content/plugins/montharchive.php
on or about line 33 (I have v 0.1):
$query = mysql_query(“SELECT *, year(post_date) as year, month(post_date) as month FROM $tableposts WHERE year(post_date)=’$year’ AND month(post_date)=’$date[month]’ ORDER BY id desc”) or die(mysql_error());
You can add
AND post_category=#
where post_category is the number of the category, which you can find in the wp_categories table. So, for instance, if you want only the category “General” you’d do the following in your database to find the #:
select cat_ID from wp_categories where cat_name=”General”;
The result, in my case, is 1. (not surprising)
So I’d change the query to:
$query = mysql_query(“SELECT *, year(post_date) as year, month(post_date) as month FROM $tableposts WHERE year(post_date)=’$year’ AND month(post_date)=’$date[month]’ AND post_category=1 ORDER BY id desc”) or die(mysql_error());
Hope this is helpful, I was looking for a different question/answer and found this one.
