Sorry the question might not make sense. I basically have a custom post type called “Projects” and I need to create a way to filter attributes of the project like “name”, “type”, etc.
For example if I have a project type called airplane, and another project type called airplane. I would want to be able to search for all projects with the name airplane, and display those in the loop.
I have looked into Taxonomies, but I do not know how to use them effectively.
This is how I did it. If you have your custom post type as “projects”, and your category as “airplane”.
If you’re not planning on using the pre-build loop you would make another one called loop-projects.php. However, it’s not necessary.
<?php $args = array( 'numberposts' => 5, 'post_type' => 'projects', 'category_name' => 'airplane'); query_posts( $args ); get_template_part( 'loop', 'projects' ); wp_reset_query(); ?>
If I understand your description right, structure goes like this:
custom post typeProject;
taxonomyassociated with Project
In current WP version you can query for this like (but will get changed in WP 3.1):
query_posts( array( 'post_type' => 'project','type' => 'airplane' ) );
See Taxonomy Parameters in Codex.
Simple as this:
// default filter: apply_filters( 'your_filter_name', $val_to_filter ); // or, make it more specific: apply_filters( 'your_filter_name_'.$val_to_filter, $val_to_filter );
You can add this somewhere before your register_post_type call, so it would look like this:
// assuming, you got an $args array to make it easy to handle: $args['name'] = apply_filters('your_name_filter', $args['name'] ); $args['name'] = apply_filters('your_name_filter_'.$args['name'], $args['name']); $args['type'] = apply_filters('your_type_filter', $args['type']); $args['type'] = apply_filters('your_type_filter_'.$args['type'], $args['type']); $name = $args['name']; unset($args['name']); register_post_type( $name, $args );
