add_filter query_post

Depends. Did you look at some of the arguments you can use with query_posts/new WP_Query?

query_posts()

actually in query_post, in can’t have operators like “>” only “=” so i can’t have post with date>today…am i wrong ?

If it is date range your are looking at, then follow the link provide above (query_posts) and look at the examples in the Time parameters section.

that’s the problem, that’s what i’ve done but this works:
query_posts(‘category_name=test&monthnum=03’);
if ( have_posts() ) : while ( have_posts() ) : the_post();

BUT NOT THIS (is is a syntax problem ?):
function filter_where($where = ”) {
//posts for March 1 to March 15, 2009
$where .= ” AND post_date >= ‘2009-03-01’ AND post_date < ‘2009-03-16′”;
return $where;
}
add_filter(‘posts_where’, ‘filter_where’);
query_posts($query_string);
if ( have_posts() ) : while ( have_posts() ) : the_post();

thanks a lot!!!!

I’m not somewhere I can test this code, but I would try something like:

$where .= " AND (wp_posts.post_date >= '2009-03-01') AND (wp_posts.post_date < '2009-03-16')";

…where wp_posts is the name of your WordPress Posts table.

thanks but i’ve still “not found” with this…
$query_string seems to be url of page ? it should be parameters of a query, should not it ?

i’ve been running into a similar issue for the past few days and i get really confused

to me it seems that

add_filter(‘posts_where’, ‘filter_where’);
doesn’t apply to
query_posts($query_string);
where $query_string would be a part of a larger MySql query

it only works with query_posts using the url like structure; but with the url like structure there’s no possibility to establish a date range
so maybe there’s another filter to be used that would affect the query at the right place/moment…

pipoulito: did you get any chance overcoming this problem?
