WordPress does this automatically if you do http://yoursite.com/?cat=1+2 (where 1 and 2 is category ids) OR http://yoursite.com/?category_name=apples+oranges (where apples and oranges is the slugs) OR something like http://yoursite.com/category/apples+oranges
Try referencing the cat query variable like so: $custom_query = new WP_Query( array( ‘cat’ => get_query_var(‘cat’) ) );
The article on Ghacks is actually a pretty silly way to do it as well. The get_header() function is actually a pretty smart function. You can do some neat things with it. For example, you can do this: get_header(‘category’); That will cause it to load the header-category.php file, if such a file exists, or the … Read more
You can use the WooCommerce hook woocommerce_after_add_to_cart_button. This hook will add content after the “Add To Cart” button. If the customer clicks on this button, the product should get added to the cart, and the customer should be send to the checkout page. Add the below code in your child theme functions.php /* Create Buy … Read more
To get the child categories of a given parent category slug, use a combination of get_category_by_slug() and get_categories(). The latter function will return an array of category objects matching the specified query arguments array; the former will return the ID of a category, given its slug. So, for example: <?php $motorbike_child_cat_args = array( ‘child_of’ => … Read more
Instead of excluding child categories, try to get only categories that have no parents (0) $cats = wp_list_categories( array( ‘parent’ => 0 ) ); That should work with no issues. EDIT: get_the_category_list() does not support advanced arguments. Your best bet is wp_get_post_categories($post_id, array(‘parent=>0’)). That will return an array of objects, you have to do the … Read more
Does your theme have a search.php to display the results? And if not then create one based on the codex examples or default theme or post the source to your index.php for troubleshooting. Edit: Your search.php is difficult to debug, try following the structure of a default theme, and put something like this in your … Read more
It’s been broken since 3.1, see: http://core.trac.wordpress.org/ticket/16622 and also http://wordpress.org/support/topic/wp-31-breaks-rss-customization-via-exclude_category NOTE: Otto’s suggested fix in that thread doesn’t work for me. Ticket suggests patch will go in for 3.1.1 and i can confirm that currently filters on pre_get_posts or parse_query fail for feeds(unfortunately).
wp_list_pages has limited functionality, and would be difficult to inject Categories into the mix without rewriting the function itself. Using the built in Menu functionality is likely the best way to go, because you can at least set individual item classes, allowing you to create Menu headers for your top level categories (having the header … Read more
