Twitter Tools has many more advanced features for Twitter, but lacks the Facebook update. If all you want to do is update your blog, Twitter, and Facebook from one place, this is the plugin for.

The only drawback I can see is that if you’re logged into Facebook when you publish a post, you will be automatically logged out.

Thanks Francesco Castaldo for a great plugin.

This becomes useful if you have uploaded images you’d like to place in a post’s gallery that are not currently children of that post.

I’ve also found that sometimes you add a new post with photos and they are not added to the gallery because you hadn’t saved the post when you uploaded them. This allows you to associate those photos with the post.

The interface isn’t that user friendly, you must enter the post ID, and I’d appreciate feedback on how to improve this.

Installation

1. Extract change-post-attachment.zip and place change-post-attachment.php `/wp-content/plugins/` directory

WordPress stores the user’s login status in a cookie named “wordpress_logged_in_COOKIEHASH,” Where COOKIEHASH there is an MD5 hash of the ‘Site URL’ option. Line 421 of wp-settings.php:


define('COOKIEHASH', md5(get_option('siteurl')));


So you can use that to check the cookie, or you can copy it from an existing cookie on your machine, or generate it in your own cookie name. First, log yourself out of WordPress, because we are going to be changing the logged in cookie name, and you won’t be able to log in or out with the old cookie name. Now we can define a new cookie name in the wp-config.php file by adding the following line somewhere in the file:

define('LOGGED_IN_COOKIE', 'my_cookie_name');

For Reference The default is defined in wp-settings.php on line 392 as:

define('LOGGED_IN_COOKIE', 'wordpress_logged_in_' . COOKIEHASH);

So now I’ll always know what the cookie name is, so I can extract the username from the cookie value.

The value contains the following info:

username|doubleHashedPassword

Now that we have a username, we can fetch user data, such as a user_id. Something like this should do the trick assuming that you have established your DB connection:

if (!empty($_COOKIE[my_cookie_name])) {

}
?>

That should work.

XML Parsing Error: XML or text declaration not at start of entity
Location: http://www.yoursite.tld/utils/test.xml
Line Number 2, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>

Somewhere along the line a new line was being placed before the XML declaration in the feeds. This caused an error to display in Firefox and other browsers instead of the feed.

I searched high and low to find where it was coming from. Disabled all me plugins, removed blank lines from code etc. To no avail. Then I noticed that the error was happening on a Mac but not in Windows. So it had to do with something about how Windows, Mac, and Linux/Unix deal with carriage returns and new line characters. I didn’t think I’d ever find the ghost new line (or return) so I tried to find a way to delete it.

Here is the hack/fix. What I’ve done is start an output buffer, and then clear it before the XML/RSS template is loaded.

In the index.php file put ob_start() like this:

<?php
ob_start();

In wp-includes/functions.php add ob_end_clean() to the beginning functions that load the feed templates.


/**
* Load the RDF RSS 0.91 Feed template.
*
* @since 2.1.0
*/
function do_feed_rdf() {
ob_end_clean();
load_template( ABSPATH . WPINC . '/feed-rdf.php' );
}

/**
* Load the RSS 1.0 Feed Template
*
* @since 2.1.0
*/
function do_feed_rss() {
ob_end_clean();
load_template( ABSPATH . WPINC . ‘/feed-rss.php’ );
}

/**
* Load either the RSS2 comment feed or the RSS2 posts feed.
*
* @since 2.1.0
*
* @param bool $for_comments True for the comment feed, false for normal feed.
*/
function do_feed_rss2( $for_comments ) {
ob_end_clean();
if ( $for_comments )
load_template( ABSPATH . WPINC . ‘/feed-rss2-comments.php’ );
else
load_template( ABSPATH . WPINC . ‘/feed-rss2.php’ );
}

/**
* Load either Atom comment feed or Atom posts feed.
*
* @since 2.1.0
*
* @param bool $for_comments True for the comment feed, false for normal feed.
*/
function do_feed_atom( $for_comments ) {
ob_end_clean();
if ($for_comments)
load_template( ABSPATH . WPINC . ‘/feed-atom-comments.php’);
else
load_template( ABSPATH . WPINC . ‘/feed-atom.php’ );
}

This worked without the change to the index.php file, but I don’t think it should have.

I tried to accomplish this with a plugin, but it wouldn’t work. since this is editing WordPress core files, these changes will need to be made again after an upgrade if the problem persists with the new version.

To allow duplicate names, but keep unique slugs, find the following code (lines 312-318) in wp-admin/admin-ajax.php:

Replace with this code:

What you are doing is changing the instances of “cat_name” with “category_nicename”, This has it check the slug for uniqueness, and not the name.

I tested briefly for myself and it seems to be working.
