A plugin that enables you to have dedicated content and/or widget sidebar for each specific page or post. For example, on a featured blog post you may want to place additional contact while on a calendar page you might want to place a calender widget or some text events or both.
<h3>Widget Support</h3>
Widget support is enabled by default and you do not have to add any code. The only recommended change is that you go to your template’s functions.php file and remove any coding containing a function similar to the one below.
<pre><code>if ( function_exists('register_sidebar') )
 register_sidebar();
</code></pre>
To enable widgets on a page or post, go to the manage screen and click ‘Add Widgets!’ to add or ‘Remove Widgets’ to remove.
<h3>Notes</h3>
This plugin is ONLY for WordPress 2.5+. It will not work with lower versions and may in fact corrupt the data in older versions. Please stay up to date with both WordPress and this plugin.
When using this plugin instead of Page Sidebars, this plugin will overwrite any of the widget configurations previously used. Also, do NOT use this script with Page Sidebars as it will lead to compatibility issues. Using this plugin will overwrite your other widget sidebars defined in your template. Proceed with caution.
For an older version of this plugin for WordPress versions 2.3.3 or lower, check out Page Sidebars.

AsideShop is a WordPress plugin which allows you to show aside posts on your blog’s front page in a different way without theme template modification.
Features:
<ul>
<li>No need to edit and modify theme templates – use your own.</li>
<li>Easily create small templates within WordPress Administration Panel to display posts differently on the front page.</li>
<li>Templates can contain dozens of pre-defined tags to use for posts and comments (e.g. <code>%posts_title%</code>, <code>%comments_count%</code>, etc.).</li>
<li>Assign templates to categories which contain aside posts.</li>
<li>Testing mode lets you preview the changes on the front page before the world sees it.</li>
<li>No extra data is added to categories or posts – AsideShop minds its own settings.</li>
<li>Upon AsideShop deactivation, all your posts are displayed as regular posts. Non-destructively.</li>
<li>Works fine with text filters (Markdown, Textiler), caching plugins (WP_Cache, WP_Super_Cache) and other plugins.</li>
<li>May not work with plugins and themes which use <a href="https://codex.wordpress.org/The_Loop" rel="nofollow ugc">The Loop</a> in uncommon way.</li>
</ul>
AsideShop is primarily intended to use with aside posts but you can use it to have posts parsed differently according to the categories the posts are placed in.
ChangeLog is available on the <a href="https://wordpress.org/extend/plugins/asideshop/other_notes/" rel="ugc">Other Notes</a> tab.
<h4>ChangeLog</h4>
1.2
<ol>
<li>
Fixed a bug which caused a disappearance of post tags if <code>%post_tags%</code> tag was used in AsideShop template. (Credit goes to <a href="http://www.tquizzle.com" rel="nofollow ugc">tquizzle</a> for pointing this out.)

</li>
</ol>
1.1
<ol>
<li>Fixed a bug which causes endless loop on certain WordPress 2.8 and 2.9 systems. Now uses <code>the_post</code> hook instead of WP_Query override. (For WordPress 2.7 and earlier versions WP_Query override is still used but I will drop support for these versions in near future.)</li>

<ol>
<li>Added new tags <code>%post_categories%</code> and <code>%post_tags%</code> to display categories and tags of aside posts. Multiple categories or tags will be separated by commas. (<code>%post_tags%</code> will only work with WordPress 2.3 and later releases.)</li>
<li>Added Italian translation by <a href="http://gidibao.net/" rel="nofollow ugc">Gianni Diurno</a>.</li>
<li>Spanish translation files were renamed from <code>asideshop-es</code> to <code>asideshop-es_ES</code>. This should work with common Spanish translations.</li>

<h4>Translation</h4>
If you wish to translate AsideShop, use <code>asideshop.pot</code> file which is included in the download. E-mail me at <code>miro [at] apollo [dot] lv</code> and I will include your translation in future releases.
<h4>Known Issues</h4>
<ul>
<li>
If AsideShop plugin is enabled, logged in user won’t see Edit This Post link as there is no such tag to use in templates.
</li>
<li>
If AsideShop plugin is enabled, templates created in WordPress Administration Panel have higher priority than those create in theme templates (using <code>is_aside()</code> function).
</li>
<li>
If text filter plugins are used (Textile, Markdown, etc), WordPress wraps the text in paragraph tags (<code>..</code>) while parsing. Therefore if you use <code>%post_content_filtered%</code> tag in AsideShop templates, the text will also be wrapped in paragraph tags.
</li>
<li>
If a post is placed in several categories and at least one category of these is selected as containing aside posts, the post will be displayed as an aside post according to the template which is assigned to the first category (in alphabetical order).
</li>
<li>
If you split aside post with <code></code> tag, only the part before <code></code> is displayed with <code>%post_content%</code> and <code>%post_content_filtered%</code> tags.
</li>
</ul>
