<p>Takes HTML content which contains flat heading elements inline with paragraphs<br />
and automatically nests them withing HTML5 <code><section></code> elements. It also<br />
conditionally prepends an <code><ol></code> Table of Contents (TOC) with links to the<br />
sections in the content, for example:</p>
<pre><code><nav class='toc'><ol>
    <li><a href="#section-first-top">First Top</a></li>
    <li><a href="#section-second-top">Second Top</a>
    <ol>
        <li><a href="#section-first-sub">First Sub</a></li>
        <li><a href="#section-second-sub">Second Sub</a></li>
    </ol>
    </li>
    <li><a href="#section-third-top">Third Top</a></li>
</ol></nav>
</code></pre>
<p>This would reflect original post content such as:</p>
<pre><code><h2>First Top</h2>
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
<h2>Second Top</h2>
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
<h3>First Sub</h2>
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
<h3>Second Sub</h2>
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
<h2>Third Top</h2>
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
</code></pre>
<p>Original post content such as this would be sectionized as follows:</p>
<pre><code><section id="section-first-top">
    <h2>First Top</h2>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
</section>
<section id="section-second-top">
    <h2>Second Top</h2>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    <section id="section-first-sub">
        <h3>First Sub</h2>
        Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    </section>
    <section id="section-second-sub">
        <h3>Second Sub</h2>
        Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    </section>
</section>
<section id="section-third-top">
    <h2>Third Top</h2>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
</section>
</code></pre>
<p>Adding a table of contents as such not only aids navigation for visitors once<br />
on the page, but Google also now provides direct links to such sections in relevant search result<br />
snippets (see <a href="http://googleblog.blogspot.com/2009/09/jump-to-information-you-want-right-from.html" title="Jump to the information you want right from the search snippets" rel="nofollow ugc">announcement</a>).<br />
So people browsing search results may be able to see your section links<br />
right from the results page and then be able to jump directly to the relevant<br />
section.</p>
<p>The start/end tags for both the sections and the TOC, as well as the prefixes<br />
used when generating the section IDs, may all be configured via the following<br />
WordPress options (with their defaults):</p>
<ul>
<li><code>sectionize_id_prefix</code>: <code>'section-'</code></li>
<li><code>sectionize_start_section</code>: <code>'<section id="%id">'</code></li>
<li><code>sectionize_end_section</code>:  <code></section></code></li>
<li><code>sectionize_include_toc_threshold</code>: <code>2</code></li>
<li><code>sectionize_before_toc</code>: <code>'<nav class="toc">'</code></li>
<li><code>sectionize_after_toc</code>: <code>'</nav>'</code></li>
<li><code>sectionize_disabled</code>: <code>false</code> (no corresponding function argument)</li>
</ul>
<p>These global WordPress options may be overridden by individual posts/pages by<br />
creating custom fields (postmeta) with the same names.</p>
<p>These options are retreived if their corresponding arguments are not supplied<br />
to the <code>sectionize()</code> function (that is, if they are <code>null</code>):</p>
<pre><code>function sectionize($original_content,
                    $id_prefix = null,
                    $start_section = null,
                    $end_section = null,
                    $include_toc_threshold = null,
                    $before_toc = null,
                    $after_toc = null)
</code></pre>
<p>This <code>sectionize()</code> function is added as a filter for <code>the_content</code> (this is<br />
disabled if the option or postmeta <code>sectionize_disabled</code> evaluates to <code>true</code>):</p>
<pre><code>add_filter('the_content', 'sectionize');
</code></pre>
<p>Noted above, the TOC is conditionally included. It is not included if:</p>
<ol>
<li>there are no headings in the content (thus there is nothing to sectionize),</li>
<li>the headings are not nested properly (see below), or</li>
<li>the heading count does not meet the threshold (or the threshold is -1)</li>
</ol>
<p>If the number of headings in the content is less than the<br />
    include_toc_threshold option/argument then the TOC is not displayed;<br />
likewise, if <code>include_toc_threshold</code> is <code>-1</code> then the TOC is not displayed.</p>
<p><em>Important!</em> Regarding headings being “nested properly”, you must ensure that<br />
you properly arrange your headings in a hierarchical manner in which no heading<br />
is immediately preceeded by another heading that is more than one level greater<br />
(e.g. an <code>h3</code> must be preceeded by an <code>h2</code> or another <code>h3</code>). For example, this<br />
works:</p>
<pre><code>h2
    h3
    h3
        h4
    h3
h2
</code></pre>
<p>But this does not:</p>
<pre><code>h2
    h4 -- fail
        h6 -- fail
h2
</code></pre>
<p>If you make such a mistake, this plugin will abort and have no effect. An error<br />
notice will be included in the HTML output in the form of an HTML comment.</p>
<p>Please see source code for additional documentation: numerous filters are provided<br />
to further customize the behavior. <em>Be one with the code!</em><br />

Sectionize

Parses HTML for sections demarcated by heading elements, wraps them in HTML5 section elements, and generates table of contents with links to each.

<p>Settings provide many different ways to Select which Theme should appear where on your WordPress web site:</p>
<ul>
<li>Just for Site Home</li>
<li>By URL (Version 5 adds support for Query keyword=value as part of a unique URL);</li>
<li>By Prefix URL, matching all URLs that begin with the same characters (“Prefix URL”);</li>
<li>By Wildcard Prefix URL with one or more Asterisks (“*”) representing arbritrary subdirectories in the URL;</li>
<li>By Query Keyword found in any URL, not matter what the Value;</li>
<li>By Query keyword=value found in any URL;</li>
<li>By Sticky Query keyword=value that sets the Theme for a given Visitor until an Override Query keyword=value is found in a future URL (Advanced Setting requiring the Visitor’s browser to accept Cookies; incompatible with certain plugins that block Cookies);</li>
<li>Everywhere (Advanced Setting that overrides the WordPress Active Theme);</li>
<li>All Pages (Advanced Setting that works with most, but not all, Themes and Plugins);</li>
<li>All Posts (Advanced Setting that works with most, but not all, Themes and Plugins).</li>
</ul>
<p>None of the Themes in the WordPress Theme Directory alter the appearance of the WordPress Admin panels.  As a result, this plugin does not allow Theme Selection entries to specify URLs for WordPress Admin panels.</p>
<p><strong>Use with Paid Themes</strong>:  On-going full scale testing of Themes by this plugin’s author is only possible if the Theme is found in the WordPress Theme Directory.  Although (Version 5 of) this plugin should now work with all Themes, any problems encountered while using Paid Themes will be difficult to diagnose.  As described in the FAQ tab, a WordPress Network (Multisite) is an alternative to this plugin, as a way to create a single web site with more than one Theme.</p>
<p>A similar situation exists with Paid Plugins.</p>
<p><strong>Use with Plugins that Cache</strong>:  You may find that you have to flush the Cache whenever you change Settings in the <em>jonradio Multiple Themes</em> plugin. Some Caching plugins only cache for visitors who are not logged in as users, so be sure to log out before testing the results of your <em>jonradio Multiple Themes</em> settings.</p>
<p><strong>Changing Theme Options (Widgets, Sidebars, Menus, Templates, Background, Header, etc.)?</strong>:  After installing and activating the plugin, see the plugin’s Settings page and click on the <strong>Theme Options</strong> tab for important information on changing Options for Themes other than the Active Theme.</p>
<p><strong>How it Works</strong>:  The plugin does not change the Active Theme defined to WordPress in the Appearances-Themes Admin panel.  Instead, it dynamically (and selectively) overrides that setting.  Which means that simply deactivating (or deleting) this plugin will restore the way that Themes were displayed prior to installing this plugin.  However, in some situations, it is possible to inadvertently alter Theme Options for the Active Theme when using either of the Methods described on the plugin’s Setting page Theme Options tab.</p>

Multiple Themes


I didn't expect it to work with wp 6.7.1 and both combination of classic theme and FSE theme. But it works! This was such a pleasant surprise! Excellent idea and realization. I would only suggest that settings interface of a plugin is a little more straightforward. Also, including regex for URL matching would be nice as well.Message to the plugin author - you can update compatibility to match WP 6.7


Fabulous!

Select different Themes for one or more WordPress Pages, Posts or other non-Admin pages.  Or Site Home.
