<p>This plugin allows you to use any HTML or PHP file as the template for any page or post.</p>
<p>Simply upload the file and select it.<br />
You can upload custom js and css files into the media library and link to them from the HTML file.</p>
<p>Options:</p>
<ul>
<li>Overwrite All: You overwrite the entire theme and use your custom file</li>
<li>Overwrite Content: Keeps the header, footer, sidebar, e.t.c. Simply overwrites the body of the page or post</li>
<li>Above Content: Your custom content is simply added to the top of the page content</li>
<li>Below Content: You custom content is placed just beneath the page content.</li>
</ul>
<h4>Adding support for custom post types</h4>
<p>By default the pulugin works with pages and posts, however, go to the settings to enable it on any other registered post type.</p>
<p>use the <code>hppp_post_types</code> filter to add more post types.</p>
<p>Like this:</p>
<pre><code>    public function post_type_modify ($post_types) {
        $post_types[] = 'custom_post_type';
        return $post_types;
    }

    add_filter( 'hppp_post_types', 'post_type_modify' );
</code></pre>


Custom HTML/PHP Post Templates

I use this on a couple sites I own and it works wonderfully.
I hope you can find it useful. 

Works like a charm

Use your HTML or PHP files for any page or post.

<p>Ultimate Post Types provides an easy interface for custom Post Types and Taxonomies management through the admin. It works fully with the WordPress post type/taxonomy API and covers the functionality from creating a post type, through adding taxonomies and custom fields, to the template which the post type uses.</p>
<p>It is a logical extension of the <a href="https://wordpress.org/plugins/ultimate-fields/" title="Easy and powerful custom fields management: Post Meta, Options Pages, Repeaters and many field types!" rel="ugc">Ultimate Fields</a> plugin and will not work if the latter is not installed.</p>
<h4>Post Types & Taxonomies</h4>
<p>You can create unlimited custom post types and custom taxonomies and set up every one of their details, as it would be possible through code.</p>
<h4>Custom Fields</h4>
<p>When creating a post type or taxonomy, you can directly assign all of Ultimate Fields’ custom fields!</p>
<h4>Templates</h4>
<p>With Ultimate Post Types you can select which template from the active theme should the post type use for it’s singular pages.</p>
<p>Additionally, you can define content that will appear before and after the standard content of the post type. That content may include custom fields, associated with the post type. This way you can create a custom template for your custom post type and display custom fields accordingly, without needing to add them to each separate post.</p>
<h4>Export</h4>
<p>You can export post types and taxonomies as stand-alone PHP code! When you add the code to your theme or plugin, the code<br />
is self-sustaining and does not need Ultimate Post Types to be installed.</p>
<p>You would only need Ultimate Fields or Ultimate Fields Premium in order to enable custom fields.</p>

Manage your Custom Post Types (CPT) and Custom Taxonomies, their templates and fields, without touching a line of code!
