如何添加特殊类（如" japan japan_index" ) 适用于日本类别的车身等级。php和类别。php之类的" archive archive_index " 我还用这段代码把类别名称放在单条上。php和索引。php主体类
// Adding categories name to body class
add_filter(\'body_class\',\'add_category_to_single\');
function add_category_to_single($classes) {
if (is_single() ) {
global $post;
foreach((get_the_category($post->ID)) as $category) {
// add category slug to the $classes array
$classes[] = $category->category_nicename;
}
}
else{
$classes[] = \'index\';
}
// return the $classes array
return $classes;
}
// Allowed classes
add_filter( \'body_class\', \'remove_some\', 10, 2 );
function remove_some( $wp_classes, $extra_classes ) {
// List of the only WP generated classes allowed
$whitelist = array( \'index\', \'japanese\', \'japan\', \'interviews\', \'travel\', \'reviews\', \'series\', \'archive\' );
// Filter the body classes
$wp_classes = array_intersect( $wp_classes, $whitelist );
// Add the extra classes back untouched
return array_merge( $wp_classes, (array) $extra_classes );
}

如果我理解你在寻找什么，这应该会起作用，它使用get_queried_object()功能：
// Adding categories name to body class on archives
add_filter(\'body_class\',\'add_category_to_body_class\');
function add_category_to_body_class( $classes ) {
// check if in category
if ( is_category() ) {
// get the queried object, in this case, a category object, and assigns to a variable
// see https://codex.wordpress.org/Function_Reference/get_queried_object
$category_object = get_queried_object();
// get the slug
$classes[] = $category_object->slug;
$classes[] = $category_object->slug . \'_index\';
}
// return the $classes array
return $classes;
}
但您可以将其混合到单个功能中：
// Adding categories name to body class on archives
add_filter(\'body_class\',\'add_category_to_body_class\');
function add_category_to_body_class( $classes ) {
if ( is_single() ) {
global $post;
// assigns post it to variable to avoid reading an array for every loop iteration
// maybe a micro optmization? Guilty as charged!
$post_id = $post->ID;
foreach( ( get_the_category( $post_id ) ) as $category ) {
// add category slug to the $classes array
$classes[] = $category->category_nicename;
$classes[] = $category->category_nicename . \'_index\';
}
}
// check if in category
else if ( is_category() ) {
// get the queried object, in this case, a category object, and assigns to a variable
// see https://codex.wordpress.org/Function_Reference/get_queried_object
$category_object = get_queried_object();
// get the slug
$classes[] = $category_object->slug;
$classes[] = $category_object->slug . \'_index\';
}
else {
$classes[] = \'index\';
}
// return the $classes array
return $classes;
}
我希望这有帮助。
