Specific Content For Mobile allows you to create pages and posts content designed for mobile devices.
This plugin DOES NOT redirect content from the desktop website: it creates brand new mobile-specific content.
It’s perfect if in some pages you need different content for the mobile version.
The best way to have a mobile version is always a fully responsive design, but in some cases you may need specific content for the mobile version.

<h3>How to add or remove specific content for the mobile version:</h3>
<ul>
<li>Click on Pages in the main admin menu</li>
<li>Go with your mouse on the page you want to modify for the mobile version and click on the action link “Create mobile version”, or click on the icon “+” you see in the devices column</li>
<li>Modify your page as you want to see it on mobile</li>
<li>Save your page mobile version</li>
</ul>
If you want to create a mobile version for your blog posts, do as explained above, but going to the list of Posts.
On mobile devices, the plugin will load the mobile version you have created for that page or post.
If you create the mobile version for a page reachable at https://your-domain.com/page-example/, and you are logged-in, you will see also https://your-domain.com/page-example-mobile/. 
But logged-out users will not see it, and the only URL that exists for the public is https://your-domain.com/page-example/.
The page reachable at https://your-domain.com/page-example/ will show the desktop content on desktop devices, and the mobile content on mobile devices The URL is always the same.
You have no redirections, and the plugin just replaces the desktop content with the related mobile version.
For more details read the <a href="https://specific-content-for-mobile.com/documentation/" rel="nofollow ugc">Documentation</a>.
<h3>Requirements</h3>
If you have a server cache plugin, be sure to set a different server cache handling for mobile devices, in another case the mobile version of your pages could also be served on desktop devices. 
E.g. <a href="https://wordpress.org/plugins/w3-total-cache/" rel="ugc">W3 Total Cache</a>, <a href="https://wordpress.org/plugins/wp-fastest-cache/" rel="ugc">WP Fastest Cache</a>, and <a href="https://wordpress.org/plugins/powered-cache/" rel="ugc">Powered Cache</a> are caching plugins that can handle the mobile cache. 
Be careful if you are using <a href="https://wordpress.org/plugins/w3-total-cache/" rel="ugc">W3 Total Cache</a> or whatever other caching plugin that gives you the possibility to manage the mobile version, DO NOT set up any redirection for mobile devices. 
If you have issues with the mobile and desktop versions with W3 Total Cache, read <a href="https://wordpress.org/support/topic/mobile-version-showing-in-desktop-view-w3-total-cache-plugin/#post-17279915" rel="ugc">Mobile version showing in desktop view – W3 Total Cache Plugin</a> 
Specific Content For Mobile DOES NOT redirect the mobile users. The URL of a page visited on mobile is exactly the same as the desktop URL.
<h3>Differences with AMP plugins</h3>
Specific Content For Mobile has nothing to do with AMP pages. It gives you the possibility to show specific content for mobile, but without any redirection, and without generating any AMP markup. 
If you want to serve AMP pages, Specific Content For Mobile is not for you. In that case, you may be interested in a plugin like <a href="https://wordpress.org/plugins/amp/" rel="ugc">AMP</a>, or <a href="https://wordpress.org/plugins/accelerated-mobile-pages/" rel="ugc">AMP For WP</a>. 
You consider Specific Content For Mobile like an alternative to AMP plugins.
<h3>Limitations of the free version</h3>
The free version supports only the mobile version of pages and posts, no custom post types, no archives, no terms.
<h4>I need advanced functionality to be integrated with this plugin.</h4>
If you need custom functionality, I offer a development service for WordPress plugin integrations and advanced feature extensions. 
Learn more about <a href="https://josemortellaro.com/advanced-functionality-for-wordpress/" rel="nofollow ugc">advanced functionality for WordPress</a>.
<h3>Additional information</h3>
As a default, WordPress doesn’t output the blog page content before the posts loop. 
Some themes do it. In this case, the blog page content output before the loop is handled by the theme templates. 
The plugin will check if the theme declares support for the blog page mobile version, if not so the blog page mobile version may take the original desktop content.
As a default Specific Content For Mobile synchronizes the post metadata. This means that when you save a post or page, if they have a mobile version, the same metadata will be saved in the mobile version. 
When you save a mobile version, the mobile version metadata will be saved also in the desktop version. 
If you want to change this behavior, go to Specific Content For Mobile settings and choose “Allow mobile versions having their own metadata”.
For the most popular SEO plugins, you can choose the metadata synchronization specifically for that plugin.

<h3>For developers</h3>
Template for mobile
If you need to use a different template file on mobile, copy the template file of your theme and put it in one of these folders:
wp-content/scfm/
wp-content/themes/theme-name/scfm
For example, if your theme is “theme-name” and you want to load a different page.php on mobile, it will be something that looks like:
wp-content/scfm/page.PHP
or
wp-content/themes/theme-name/page.php
In the case of mobile devices, Specific Content For Mobile will look for the custom template file first in wp-content/themes/theme-name/scfm and if it doesn’t find it in wp-content/scfm.
Integration with other plugins
If you add an option for the metadata synchronization of an external plugin, you can use the filter “eos_scfm_meta_integration_array”.
Here an example:
<pre><code>add_filter( 'eos_scfm_meta_integration_array','my_custom_scfm_meta_integration',20,2 );
//It adds an option to synchronize your plugin meta data.
function my_custom_scfm_meta_integration( $arr,$options ){
 $slug = 'my_custom_meta';
 $arr[$slug] = array(
 'is_active' => defined( 'WPSEO_FILE' ),
 'args' => array(
 'title' => __( 'My custom meta synchronization','my-textdomain' ),
 'type' => 'select',
 'value' => isset( $options[$slug] ) ? esc_attr( $options[$slug] ) : 'synchronized',
 'options' => array(
 'synchronized' => __( 'Synchronize desktop and mobile metadata','my-textdomain' ),
 'separated' => __( 'Allow mobile versions having their own metadata','my-textdomain' )
 ),
 ),
 'prefix' => array( '_my_plugin' ),
 'default' => 'synchronized'
 );
 return $arr;
}
</code></pre>
Then you will see your custom option “My custom meta synchronization” in the main settings page.
Helper functions
In your theme, you can use the following functions to give full support to the mobile version content:
<pre><code>eos_scfm_related_desktop_id( $post_id );
</code></pre>
given the post ID, it will get the post ID of the related desktop version.
<pre><code>eos_scfm_related_mobile_id( $post_id );
</code></pre>
given the post ID, it will get the post ID of the related mobile version.
Theme support
To add the theme support to the blog content, you can add this line in your theme support action hook:
<pre><code>add_theme_support('specific_content_form_mobile',array( 'posts_page' => true ) );
</code></pre>
