The Page Blocks plugin extends your WordPress pages by combining the dynamic content of widgets with the static content of pages. Up to four “blocks” can be added to each page (two above and two below the page’s content), and widgets can be added to each block in the same way they are added to sidebars.
Content can be edited simply through the admin backend, removing the need for custom page templates for all but the most complex of blog designs. Two examples of what can be done with the plugin are shown in the Screenshots section:
<ul>
<li>
A home page with a welcome message in the page content above a widget displaying News posts on the left and a widget displaying the most recently created post on the right.
</li>
<li>
A page showing a dynamically generated “Thank You” message for a customer returning from PayPal in a single page block at the top of the page using a standard text widget and the Exec-PHP plugin (before and after images).
</li>
</ul>
More detailed information is available on the <a href="http://wordpress.softwud.com" title="Page Blocks Plugin Website" rel="nofollow ugc">Page Blocks Plugin Website</a>, as well as support and contact information. You can also contact SoftWUD through this site if you’d like a custom theme, plugin, or widget developed.
<h4>Features</h4>
<ul>
<li>
No file editing needed
Blocks are configured through the Page Write / Manage and Widgets admin pages. There is no need to edit PHP code or modify your theme in any way.
</li>
<li>
Blocks will work even if the theme is changed
As long as the theme you use employs the WordPress “Loop” mechanism (and pretty much all themes do) then there won’t be any problems. Even if the “Loop” has been modified.
</li>
<li>
Each page can be configured with a different set of page blocks
There are four blocks that can be enabled for each page – Top Left, Top Right, Bottom Left, and Bottom Right. For example you may have a Top Left on one page, a Bottom Left and Bottom Right on another, and all others may have none at all.
</li>
<li>
Each block can have it’s own CSS styling rules
The plugin provides default CSS styling for the blocks assuming that all four blocks are enabled on a page. However CSS styling rules can be applied through the Page Write / Manage admin page to override these, or even your own theme’s styling rules.
</li>
<li>
The plugin supports password protected pages
If you protect your page content with a password, the page blocks will also be hidden until the user enters a valid password.
</li>
</ul>

Page Blocks

This plugin extends WordPress pages by allowing widgets to be placed above and below the page content reducing the need to code custom page templates.

Designed for simplicity and flexibility, Simple Page Sidebars gives WordPress users, designers, and developers the ability to assign custom sidebars to individual pages–without making any template changes. Existing sidebars can also be assigned in quick edit and bulk edit modes, helping save you time.
In contrast to some of the more complicated plugins available, Simple Page Sidebars aims for basic, core-like functionality and integration that’s easy to use without polluting your admin panel. And due to the way sidebars are saved, it utilizes built-in WordPress caching, so your site won’t be bogged down with additional queries.
Simple Page Sidebars also ships with a “Widget Area” widget for pulling all the widgets from one sidebar into another.
<h3>Benefits</h3>
<ul>
<li>No more site-wide, generic sidebars. Each page (or section) can have its own widgets.</li>
<li>Complete control over the names of your custom sidebars.</li>
<li>Assign the same sidebar to multiple pages.</li>
<li>Modify a page’s sidebar without creating an unnecessary revision.</li>
</ul>
<h3>Advanced Usage</h3>
If you want to assign custom sidebars to archive pages or replace multiple sidebars per page, this plugin likely won’t be the best solution. However it’s flexible enough to handle a wide range of page-based use cases. It can even be configured to work with Custom Post Types by adding a couple lines of code:
<pre><code>function myprefix_init() {
 add_post_type_support( '{{post_type}}', 'simple-page-sidebars' );
}
add_action( 'init', 'myprefix_init' );
</code></pre>

<h3>Notes</h3>
<h3>Custom Loops</h3>
If your page has any custom loops or queries, they need to be followed by <code>wp_reset_query()</code>, otherwise the global <code>$post</code> variable will no longer reference the correct post and by the time the sidebar is displayed, Simple Page Sidebars won’t know which page is being viewed, possibly leading to an unexpected sidebar being displayed.
<h3>Theme Sidebars</h3>
Some themes register different sidebars for their page templates, which means there isn’t a default sidebar that can be replaced. To use Simple Page Sidebars in this instance, you can create a child theme and force page templates with custom sidebars to use the default sidebar.

Initially I was disappointing it didn't work on custom post types, but then bothered to read the instructions.
The developer had bothered to put down exactly how to do this:
function myprefix_init() {
    add_post_type_support( '{{post_type}}', 'simple-page-sidebars' );
}
add_action( 'init', 'myprefix_init' );
Works a treat! Very flexible. Great job.



Works great

Easy to understand how to use it and does exactly what it says. Great plugin.



Works great!

Easily assign custom, widget-enabled sidebars to any page.
