php - Wordpress custom post type categories -

-

hey. using custom post type in wordpress. register custom post type this:

        register_post_type("lifestream", array(             'label' => 'lifestream',             'public' => true,             'hierarchical' => true,             'menu_position' => 5,             'supports' => array('title','editor','author','thumbnail','comments','custom-fields'),             'taxonomies' => array('category','post_tag'),             'query_var' => true,             'publicly_queryable' => true,             'exclude_from_search' => false,             'caller_get_posts' => 1          ));         register_taxonomy_for_object_type('category', 'lifestream');         register_taxonomy_for_object_type('post_tag', 'lifestream');

in theme (the loop template) combine posts , custom post type, using query_posts() these parameters:

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; $args = array(     'post_type' => array('post', 'lifestream'),     'paged' => $paged,     'cat' => $wp_query->get('cat'),     'tag' => $wp_query->get('tag'),     'year' => $wp_query->get('year'),     'monthnum' => $wp_query->get('monthnum'),     'post_status' => 'publish',     'showposts' => 3 ); query_posts($args);    # loop      while ( have_posts() ) : the_post();  # markup endwhile;   if($wp_query->max_num_pages > 1):  # next_posts_link / previous_posts_link endif;  wp_reset_query();

this working far. but, got problems category , tags pages. if call frontpage fine , can paginate through pages getting correct results.

and, if call paged url, e.g. /category/mycat/page/2 404 thrown. there definitly should posts. no matter if there custom type posts or normale posts in category. suppose parameters query_posts() aren´t correct, don´t know ...

it seems $wp_query->max_num_pages has wrong value. why? register taxonomies (i use categories , tags custom post types) correctly?

do have idea do? lot!

i have encountered exact same problem , couldn't find solution anywhere! internets full of resources topic none provided correct answer issue.

here's correct answer searching. put below code in functions.php in theme's root directory.

function init_category($request) {     $vars = $request->query_vars;     if (is_category() && !is_category('blog') && !array_key_exists('post_type', $vars)) :         $vars = array_merge(             $vars,             array('post_type' => 'any')         );         $request->query_vars = $vars;     endif;     return $request; } add_filter('pre_get_posts', 'init_category');

all credits go mike posted on wordpress.com. cheers!

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
