我正在使用Hybrid core framework尝试添加我的类item 在…上hybrid_post_attributes 使用此代码的筛选器生成的类。

add_filter( \'hybrid_post_attributes\', \'my_post_atributes\');
function my_post_atributes($attributes){
return  $attributes[\'class\'] = substr_replace($attributes[\'class\'], \' item\', -1);
}

我希望将我的“item”类添加为“hybrid\\u post\\u attributes”类中的最后一个类。这是hybrid_post_attributes 作用

function hybrid_post_attributes() {

    $attributes = array();
    $output     = \'\';

    $attributes[\'id\']    = \'post-\' . get_the_ID();
    $attributes[\'class\'] = join( \' \', hybrid_get_post_class() );
    $attributes = apply_atomic( \'post_attributes\', $attributes );

    foreach( $attributes as $attr => $value )
        $output .= " {$attr}=\'{$value}\'";

    echo $output;
}

这里是hybrid\\u get\\u post\\u类函数。

function hybrid_get_post_class( $class = \'\', $post_id = null ) {
    static $post_alt;

    $post = get_post( $post_id );

/* Make sure we have a real post first. */
if ( !empty( $post ) ) {

    $post_id = $post->ID;

    /* Add hentry for microformats compliance, the post type, and post status. */
    $classes = array( \'hentry\', $post->post_type, $post->post_status );

    /* Post alt class. */
    $classes[] = \'post-\' . ++$post_alt;
    $classes[] = ( $post_alt % 2 ) ? \'odd\' : \'even alt\';

    /* Author class. */
    $classes[] = \'author-\' . sanitize_html_class( get_the_author_meta( \'user_nicename\' ), get_the_author_meta( \'ID\' ) );

    /* Sticky class (only on home/blog page). */
    if ( is_home() && is_sticky() && !is_paged() )
        $classes[] = \'sticky\';

    /* Password-protected posts. */
    if ( post_password_required() )
        $classes[] = \'protected\';

    /* Has excerpt. */
    if ( post_type_supports( $post->post_type, \'excerpt\' ) && has_excerpt() )
        $classes[] = \'has-excerpt\';

    /* Has <!--more--> link. */
    if ( !is_singular() && false !== strpos( $post->post_content, \'<!--more-->\' ) )
        $classes[] = \'has-more-link\';

    /* Post format. */
    if ( current_theme_supports( \'post-formats\' ) && post_type_supports( $post->post_type, \'post-formats\' ) ) {
        $post_format = get_post_format( $post_id );
        $classes[] = ( ( empty( $post_format ) || is_wp_error( $post_format ) ) ? \'format-standard\' : "format-{$post_format}" );
    }

    /* Add category and post tag terms as classes. */
    if ( \'post\' == $post->post_type ) {

        foreach ( array( \'category\', \'post_tag\' ) as $tax ) {

            foreach ( (array)get_the_terms( $post->ID, $tax ) as $term ) {
                if ( !empty( $term->slug ) )
                    $classes[] = $tax . \'-\' . sanitize_html_class( $term->slug, $term->term_id );
            }
}

我使用过滤器的方式是否错误<谢谢。

add_filter(\'post_class\', \'my_post_attributes\');
function my_post_attributes($classes){
  $classes[] = \' item\';
  return $classes;
}

add_filter(\'post_class\', \'my_post_attributes\');
function my_post_attributes($classes){
  return array_merge($classes,array(\'item\'));
}

add_filter( \'hybrid_post_attributes\', \'my_post_atributes\');
function my_post_atributes($attributes){
    return  $attributes[\'class\'] = substr_replace($attributes[\'class\'], \' item\', -1);
}

add_filter( \'hybrid_post_attributes\', \'my_post_atributes\');
function my_post_atributes($attributes){
    // Modify
    $attributes[\'class\'] = substr_replace($attributes[\'class\'], \' item\', -1);
    // Return
    return $attributes;
}
