Set homepage to only display posts from one tag

Question

I'd like my homepage to only display posts from a single tag. Is this possible? If yes, please advise.

For instance,

www.mysite.com/tag/sometag

will only display posts with the sometag tag, but how do I get www.mysite.com to automatically display only the posts seen on

www.mysite.com/tag/sometag page?

Answer 1

You should use pre_get_posts to alter the main query on the home page.

With the proper conditional tags and parameters (check WP_Query for available parameters) you can achieve what you need

You can do the following to just display posts from a given tag on your homepage

add_action( 'pre_get_posts', function ( $query ) {
    if ( !is_admin() && $query->is_home() && $query->is_main_query() ) {
        $query->set( 'tag', 'SLUG_OF_TAG' );
    }
});

For that; first you have to make Custom Page template and add following loop in it and customize it in what ever way you want.

<?php

    $args=array(
      'tag' => 'yourtag',
      'showposts'=>5     // set number of post you want to display
    );
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      while ($my_query->have_posts()) : $my_query->the_post(); ?>

        <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>

        // display what ever you want in this post

      <?php
      endwhile;
    }
  wp_reset_query();  // Restore global post data stomped by the_post().
?>

Then create a Page and select this custom page template for it.

Next from settings set this page as static home page and you are ready to GO.

Custom wp queries will work perfectly, but in many cases pagination or a other elements gone or be "broken".

I use a not a ideal but "simplest" way: 301 redirection in Custom Page template for a orginal WP tag page.

Example piece of code:

<?php
/**
 * Template Name:  Your Custom Redirect Name
 */
header("HTTP/1.1 301 Moved Permanently");
header("Location: hxxp://yoursite.com/tag/your-tag-slug/");
 ?>
