firefox not showing vertical scrollbars in blog

jaredh123 (Jared Henderson) — Thu, 21 Feb 2008 20:40:24 GMT

hey everyone,

I'm new here and wondering if someone can help me out. i have a couple wordpress blogs i've built for clients, and i'm occasionally getting a wierd behavior in Firefox Win/Mac: sometimes even though there is plenty of content below the fold, no vertical scrollbar will show at all. it only does this on firefox.

here's an example (must view in firefox):

http://www.lorihedrickphotography.com/blog/

and i've tried adding this:

html {
height:101%;
overflow-y:scroll;
}

i looked at it with firebug, it validates. i'm stumped! any help would be greatly appreciated.

MetaWeblog API in PHP

danielsanII (Daniel Lorch) — Sun, 25 Nov 2007 18:34:43 GMT

Implementation of the MetaWeblog API http://www.xmlrpc.com/metaWeblogApi in PHP.



/**

 * Skeleton file for MetaWeblog API http://www.xmlrpc.com/metaWeblogApi in PHP

 * Requires Keith Deven's XML-RPC Library http://keithdevens.com/software/xmlrpc and store it as xmlrpc.php in the same folder

 * Written by Daniel Lorch, based heavily on Keith Deven's examples on the Blogger API.

 */



require_once dirname(__FILE__) . '/xmlrpc.php';



function metaWeblog_newPost($params) {

  list($blogid, $username, $password, $struct, $publish) = $params;

  $title = $struct['title'];

  $description = $struct['description'];





  // YOUR CODE:

  $post_id = 0; // id of the post you just created





  XMLRPC_response(XMLRPC_prepare((string)$post_id), WEBLOG_XMLRPC_USERAGENT);

}



function metaWeblog_editPost($params) {

  list($postid, $username, $password, $struct, $publish) = $params;





  // YOUR CODE:

  $result = false; // whether or not the action succeeded





  XMLRPC_response(XMLRPC_prepare((boolean)$result), WEBLOG_XMLRPC_USERAGENT);

}

I've Googled this about 20 times - documenting it here for convenience.



curl -d url=TRACKBACK_URL -d title=TRACKBACK_TITLE -d blog_name=TRACKBACK_BLOG_NAME -d excerpt=TRACKBACK_EXCERPT URL

Use the contents of a WordPress database in your Rails app

jazzido (Manuel Aristarán) — Mon, 30 Jan 2006 04:10:02 GMT

These two models can be used to access the posts and associated comments of a WordPress database.



class WpBlogComment < ActiveRecord::Base



  # if wordpress tables live in a different database (i.e. 'wordpress') change the following

  # line to set_table_name "wordpress.wp_comments"

  # don't forget to give the db user permissions to access the wordpress db

  set_table_name "wp_comments"

  set_primary_key "comment_ID"



  belongs_to :post , :class_name => "WpBlogPost", :foreign_key => "comment_post_ID"



  validates_presence_of :comment_post_ID, :comment_author, :comment_content, :comment_author_email

  

  def validate_on_create

    if WpBlogPost.find(comment_post_ID).comment_status != 'open'

      errors.add_to_base('Sorry, comments are closed for this post')

    end

  end



end



class WpBlogPost < ActiveRecord::Base



  set_table_name "wp_posts"

  set_primary_key "ID"



  has_many :comments, :class_name => "WpBlogComment", :foreign_key => "comment_post_ID"



  def self.find_by_permalink(year, month, day, title)

    find(:first, 

         :conditions => ["YEAR(post_date) = ? AND MONTH(post_date) = ? AND DAYOFMONTH(post_date) = ? AND post_name = ?", year.to_i, month.to_i, day.to_i, title])

  end

end
