It just take a little bit more complicated logic: function alternating_post_class($classes) { static $counter = 1; switch ($counter) { case 1: $classes[] = ‘full-width’; break; case 2: case 3; $classes[] = ‘half-width’; break; } $counter = ($counter == 3) ? 1 : $counter + 1; return $classes; } add_filter(‘post_class’, ‘alternating_post_class’);
For each extra functionality, you are going to pay for How much would depend on the function or action. It is like @TomJNowell said, even a simple echo statement costs time and memory although it is really minute and insignificant. The real issue here is db calls as they can get very expensive depending on … Read more
Several classes have been added since WordPress 2.8 (when the WPEngineer post was written). I would refer directly to the body_class() Codex entry, which currently lists the following: rtl home blog archive date search paged attachment error404 single postid-(id) page-id-(page_id) attachmentid-(id) attachment-(mime-type) author author-(user_nicename) category category-(slug) tag tag-(slug) page-parent page-child parent-pageid-(id) page-template page-template-(template file name) … Read more
That is because the get_the_tags() function returns an array with the tag id as the key value. You could use array_values( get_the_tags( $post->ID ) ). That should do the trick.
What it does post_class adds classes to the posts on a post by post basis, usually adding them to some kind of post “wrapper”. This allows for the targeting of posts with CSS rules according to various criteria– category, tag, sticky, format, etc. That is, theme authors, plugin authors, and individual users can write CSS … Read more
You can add custom class to post thumbnails. the_post_thumbnail accepts array of attribute $attr where you can specify image class. So your code will be. <div class=”home-featured-img”> <?php if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it. the_post_thumbnail( ‘full’, array( ‘class’ => ‘responsive-class’ ) ); // show … Read more
Use the post_class filter to test multiple conditions: function wpa_post_class( $classes ) { global $post; if( ! has_post_thumbnail() ) $classes[] = “no-image”; if( get_the_content() == “” ) $classes[] = “no-content”; return $classes; } add_filter( ‘post_class’, ‘wpa_post_class’ ); Then your html will just be: <li id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>
Simple fix: <div <?php post_class(“clearfix”); ?>> See post_class() for more details
I usually include the following parent variable, filter and method in my plugins to account for this case. I’ve never been sure if this is the “right” way of going about it, but feels better than applying it with javascript. class Plugin_Name { private $parent=”services”; // ideally this is a setting in your plugin, not … Read more
If “line 45” is the one that starts with $element->classes[] in your display_element method then try something like this: public function display_element( $element, &$children_elements, $max_depth, $depth = 0, $args, &$output ) { $element->has_children = ! empty( $children_elements[ $element->ID ] ); if ( ! isset( $element->classes ) ) { $element->classes = array(); } $element->classes[] = ( … Read more
