drupal 7 设置SEO函数

　　drupal 7 设置SEO主要利用drupal_add_html_head和drupal_set_title两个函数

 

/**
  * set seo
  * $data = array('title' => ,'keywords' =>, 'description' => );
  *
  */
  function set_seo($data = array()) {
    if($data['description']) {
      $meta_description = array(
            '#type' => 'html_tag',
            '#tag' => 'meta',
            '#attributes' => array(
                'name' => 'description',
                'content' => $data['description'],
            )
      );
      drupal_add_html_head($meta_description,'meta_description');


    }
  if($data['keywords']) {
    $meta_keywords = array(
            '#type' => 'html_tag',
            '#tag' => 'meta',
            '#attributes' => array(
                'name' => 'keywords',
                'content' => $data['keywords'],
            )
    );
      drupal_add_html_head($meta_keywords,'meta_keywords');
    
  }
  if($data['title']) {
    drupal_set_title($data['title']);
 
  }

  }
