下面是一个如何更新kses和TinyMCE以允许在WordPress中选择data-*属性的示例。Reference

add_action( \'after_setup_theme\', \'x_kses_allow_data_attributes_on_links\' );
function x_kses_allow_data_attributes_on_links() {
  global $allowedposttags;

    $tags = array( \'a\' );
    $new_attributes = array(
        \'data-foo\' => array(),
        \'data-bar\' => array(),
    );

    foreach ( $tags as $tag ) {
        if ( isset( $allowedposttags[ $tag ] ) && is_array( $allowedposttags[ $tag ] ) )
            $allowedposttags[ $tag ] = array_merge( $allowedposttags[ $tag ], $new_attributes );
    }
}

add_filter( \'tiny_mce_before_init\', \'x_tinymce_allow_data_attributes_on_links\' );
function x_tinymce_allow_data_attributes_on_links( $options ) { 
    if ( ! isset( $options[\'extended_valid_elements\'] ) ) 
        $options[\'extended_valid_elements\'] = \'\'; 

    $options[\'extended_valid_elements\'] .= \',a[data-foo|data-bar|class|id|style|href]\';

    return $options; 
}
