As wp_list_pages() has an argument of walker, you can use that to replace what is being used by walk_page_tree() as walker class internally. @Brady has left a nice example in this answer. class WPSE113482PageWalker extends Walker_Page { function start_el( &$output, $page, $depth, $args, $current_page ) { // Build $output here and apply your class for … Read more
Note – I recommend using the hook suggested by @Chip Bennett in another answer Here’s the modified version of that filter – function wpse_filter_post_class( $classes ) { $my_post_class = get_post_meta($post->ID, “your_meta_name”); if( $my_post_class != ” ) $classes[] = $my_post_class; return $classes; } add_filter( ‘post_class’, ‘wpse_filter_post_class’ ); You can setup a Custom fileds for that – … Read more
The my_custom_class() function is using the class name my-custom-class, but the CSS is targeting the class my_custom_class. These two strings should be exactly the same: .my-custom-class { margin-top: 350px !important; } Also, it would be a little cleaner to handle all of the body_class stuff in a single callback function: add_action( ‘body_class’, ‘my_custom_class’); function my_custom_class( … Read more
Perhaps something like: function mytheme_get_post_class_parent_cats() { $parent_cat_classes = array(); // Get parent categories $post_cats = wp_get_post_categories(); // Loop through post categories foreach ( $post_cats as $post_cat ) { $cat_parents = get_category_parents( $post_cat , false, ‘,’, true ); // if there are any parent categories if ( $cat_parents ) { // create an array $cat_array = … Read more
Here’s a solution that adds additional sticky classes, one for the post ID and one for the sticky post counter. /** * Adds .featured-{$post_id} and .featured-{$sticky_counter} * class names to sticky posts. * * @param array $classes An array of post classes. * @param array $class An array of additional classes added to the post. … Read more
The post_class() function just is a wrapper for get_post_class(). Keep in mind that the latter does not echo, but returns an Array so you have to do something like what post_class() does: $classes = join( ‘ ‘, get_post_class() ); Your code (could) would look like the following. I changed the if check as well to … Read more
The ID can/should be given without quotes (otherwise if you a page with ‘38034’ as slug/post_name, this will be used instead of the page with the ID 38034). And you want to return $classes no matter if you added your own or not. add_filter(‘body_class’, ‘custom_body_class’); function custom_body_class($classes) { if (is_page(38034)) $classes[] = ‘new-class’; return $classes; … Read more
This is expected (or at least: designed) behavior. Here is a portion of the Codex on that: The post_class CSS classes appear based upon the post pageview Conditional Tags as follows. Category Category template files and pageviews displaying posts feature the class selectors: post post-id category-ID category-name Of course, you can hook a custom filter … Read more
The post_class function does also accept an array of classes. You can pass them to the function as follows: $classes = [ ‘card’, ‘grid-item’, ‘wow’, ‘fadeInUp’, $termsString ]; <div <?php post_class ( $classes ); ?>> … </div> You can store the custom field’s value inside a variable, and then pass it to the function just … Read more
I’m fairly certain the problem is that some template tags rely on the global $post variable. Using setup_postdata() as you are now, will not alter $post. If you replace all the instances of $pageChild with $post, everything should work. However, I would strongly recommend using the WP_Query class and setting up your post data with … Read more
