README

HM_Rewrite and HM_Rewrite_Rule are wrappers for the WordPress rewrite / wp_query system.

The goal of HM_Rewrite and associated fuctions / classes is to make it very easy to add new routing points with new pages (as in dynamic pages, post_type_archive etc). It basically wraps a few tasks into a nice API. Everything (almost) you need for setting up a new routing page can be done all at once, relying heavily on PHP Closures. It essentially wraps adding to the rewrite_rules, adding your template file to template_redirect, wp_title hook, body_class hook, parse_query hook etc. Also also provides some callbacks for conveniance. Each rewrite rule is an instance of HM_Rewrite_Rule. Here you add the regex / wp_query vars and any other options for the "page". For example a callback function to parse_request to add additional query vars, or a callback * body_class. There is also a wrapper function for all of this in one call hm_add_rewrite_rule(). hm_add_rewrite_rule() is generally the recommended interface, you can interact with the underlying objects for more advanced stuff (and also tacking onto other rewrite rules)Simple use case example:

hm_add_rewrite_rule( array(
  'regex'     => '^users/([^/]+)/?',
  'query'     => 'author_name=$matches[1]',
  'template'  => 'user-archive.php',
  'body_class_callback' => function( $classes ) {
    $classes[] = 'user-archive';
    $classes[] = 'user-' . get_query_var( 'author_name' );

    return $classes;
  },
  'title_callback' => function( $title, $seperator ) {
    return get_query_var( 'author_name' ) . ' ' . $seperator . ' ' . $title;
  }
) );

A more advanced example using more callbacks:

hm_add_rewrite_rule( array(
  'regex'    => '^reviews/([^/]+)/?', // a review category page
  'query'    => 'review_category=$matches[1]',
  'template' => 'review-category.php',
  'request_callback' => function( WP $wp ) {
    // if the review category is "laptops" then only show items in draft
    if ( $wp->query_vars['review_category'] == 'laptops' )
      $wp->query_vars['post_status'] = 'draft';
  },
  'query_callback' => function( WP_Query $query ) {
    //overwrite is_home because WordPress gets it wrong here
    $query->is_home = false;
  },
  'body_class_callback' => function( $classes ) {
    $classes[] = get_query_var( 'review_category' );
    return $classes;
  },
  'title_callback' => function( $title, $seperator ) {
    return review_category . ' ' . $seperator . ' ' . $title;
  },
  'rewrite_tests_callback' => function() {
    return array(
      'Review Category' => array(
        '/reviews/foo/',
        '/reviews/bar/',
      ),
    );
  }
) );
