This is a really useful little snippet I found in the WordPress Codex. It allows us to check whether a page is within a specified tree, e.g. whether a page is a certain ID or if it is a subpage of that ID.

Here’s the function:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

function is_tree($pid)
{
	global $post;         // load details about this page
	$anc = get_post_ancestors( $post->ID );
	foreach($anc as $ancestor) {
		if(is_page() && $ancestor == $pid) 
		{
			return true;
		}
	}
	if(is_page()&&(is_page($pid))) 
               return true;   // we're at the page or at a sub page
	else 
               return false;  // we're elsewhere
 
}

Then we can perform the check from within the WordPress loop like this:

1
2
3
4

if ( is_tree('4') )
	{
		// run this code
	}

The above snippet will check if the current page has an ID of 4 of if the parent of the current page has an ID of 4. If the check comes back true, the code within the brackets will be run.

If you wish to set a minimum word count for your posts (this can be useful for a variety of things, including maintaining a clean layout), simply add the following snippet to your functions.php file and set the number to whatever you wish.

1
2
3
4
5
6
7
8

function minWord($content)
{
	global $post;
	$content = $post->post_content;
	if (str_word_count($content) < 100 ) //set this to the minimum number of words
	wp_die( __('Error: your post is below the minimum word count.') );
}
add_action('publish_post', 'minWord');

If an author tries to publish a post with fewer than the minimum, WordPress will kick out an error.

Nice and simple.

Simple Social Network Sharing for WordPress

Simple Sharing is an easy to use social network sharing plugin that adds a “share” box to each of your individual posts, allowing your readers to easily share your post over many of the most popular social sharing networks.

But What’s Different from Others

Unlike many social network sharing plugins, Simple Share floats just to the left of your content and scrolls with the page as readers scroll, keeping it always in view.

Why does this matter?

Readers have a tendency to quit reading before they get to the bottom of the post, where most social network sharing links are. Simple Share is always in view, enticing readers to share your article from the first word on.

Features

• 8 integrated sharing protocols
• Easy to use admin interface
• Complete positioning control
• Styling control
• Ability to choose which protocols to display
• jQuery enhanced fancy tool tips

This plugin will very easily let you restrict content on your WordPress site to registered users. It permits you to restrict entire posts / pages or individual sections of content within a post or page.

Screencast Demo

Features

• Restrict entire posts / pages.
• Restrict sections of content.
• Unlimited number of restricted areas.

Usage

First upload to wp-content/plugins and click activate from the WordPress plugins menu.

Accepted userlevel values are:

• admin
• editor
• author
• subscriber

A premium version of this plugin is coming soon with many more awesome features.

Changelog

Updated July 23, 2010

Version 1.1 fixes a problem where all posts would be set to “restricted” even without a restriction level set. This problem was caused the value of “none” not automatically being inserted into the database. I have changed the way that the plugin perceives whether a restriction level is set, eliminating this problem entirely.
