Have you ever wanted to integrate external content such as a specific post of an external website into your WordPress website? But treat it like any other post? That is, have it appear as teaser or part of a specific (pseudo) archive?
This is exactly when External Content kicks in.
<h4>Usage</h4>
External Content registers a custom post type that, by default, supports title, content, excerpt and thumbnail. This can be customized, though. Managing your posts in your backend is no different from any other post type. Create a new post, give it a title, write some text, define an individual excerpt, and set a post thumbnail, if you wish. Then assign each post an individual external URL by means of the according meta box. This external URL will be used as the post’s permalink.
Filters
In order to customize certain aspects of the plugin, it provides you with several filters. For each of these, a short description as well as a code example on how to alter the default behavior is given below. Just put the according code snippet in your theme’s <code>functions.php</code> file or your customization plugin, or to some other appropriate place.
<code>external_content_args</code>
If you want to alter a specific post type argument but you can’t find a fitting filter, there’s <code>external_content_args</code>, which provides you with the complete args array.
<pre><code>/**
 * Filter the post type args.
 *
 * @param array $args Post type args.
 */
add_filter( 'external_content_args', function( $args ) {

 // Use hierarchical external content
 $args[ 'hierarchical' ] = TRUE;

 return $args;
} );
</code></pre>
<code>external_content_description</code>
The post type description can be customized by using the <code>external_content_description</code> filter.
<pre><code>/**
 * Filter the post type description.
 *
 * @param string $description Post type description.
 */
add_filter( 'external_content_description', function() {

 // Provide a description
 return 'Simple post type for handling external content like any other post.';
} );
</code></pre>
<code>external_content_labels</code>
In case you don’t like the labels, easily adapt them to your liking.
<pre><code>/**
 * Filter the post type labels.
 *
 * @param array $labels Post type labels.
 */
add_filter( 'external_content_labels', function( $labels ) {

 // A little more horror, please...
 $labels[ 'not_found' ] = 'ZOMG, no external content found!!1!!1!!oneone!!!1!eleven!1!';

 return $labels;
} );
</code></pre>
<code>external_content_meta_key</code>
If you want to alter the meta key for the external URL, feel free to do it via this filter.
<pre><code>/**
 * Filter the meta key.
 *
 * @param string $meta_key Meta key.
 */
add_filter( 'external_content_meta_key', function() {

 // Let's Shrekify the meta key
 return 'far_far_away';
} );
</code></pre>
<code>external_content_post_type</code>
Yes, you can also alter the post type (slug).
<pre><code>/**
 * Filter the post type.
 *
 * @param string $post_type Post type.
 */
add_filter( 'external_content_post_type', function() {

 return 'exotic_stuff';
} );
</code></pre>
<code>external_content_supports</code>
This filter provides you with the post type supports.
<pre><code>/**
 * Filter the post type supports.
 *
 * @param array $supports Post type supports.
 */
add_filter( 'external_content_supports', function( $supports ) {

 // If your theme uses the excerpt for teasers, just remove the editor to prevent confusion
 foreach ( $supports as $key => $value ) {
 if ( 'editor' === $value ) {
 unset( $supports[ $key ] );
 }
 }

 return $supports;
} );
</code></pre>
<code>external_content_use_external_url</code>
The permalink of external content is, by default, replaced with the post’s according external URL (i.e., post meta). To disable this behavior, just do the following:
<pre><code>/**
 * Filter the usage of the external URL as permalink.
 *
 * @param bool $use_external_url Use the external URL as permalink?
 */
add_filter( 'external_content_use_external_url', '__return_false' );
</code></pre>

Hyperspective

Custom URL Replacer scans your post content for anchor tags where the visible text exactly matches the full URL. If the URL is external to your site, it replaces the text with a custom string. Additionally, if the “Open in New Tab” setting is enabled, the plugin forces all external links to open in a new tab by adding target=”_blank” and rel=”noopener noreferrer” automatically. A settings page is provided under the Tools menu so you can customize the replacement text and toggle the new tab option.
