How to organise via Custom Fields on Category Page

Question

I have a custom field named: eventdate The posts are all in the standard post type. I want to order by this field ascending. I have tried over 15 different solutions but no joy . Every post simply gets turned into a list of all posts.

I have tried all solutions both before and after the following.

if(have_posts()){
 while (have_posts()) : the_post();

Please help, I have been trying to sort this for at least 14 hours.

Answer 1

you can use query_posts to sort the post by you custom field, Add this before you loop

query_posts( $query_string . 'meta_key=eventdate&order=ASC&orderby=meta_value');
