WordPress Taxonomy, listing ONLY the single taxonomies

Question

So I have a custom Taxonomy 'Sectors'.

I am trying to display all the single posts in 'Sectors' in a list, just a basic list.

I currently do have it so, it will display the category, then a sub category, then the list from there.

I also have this, which lists all posts - (NOT TAXONOMY) :

<?php 
      $uncat = get_cat_ID('uncategorised');
      $args = array(
        'posts_per_page' => 5,
        'category__not_in' => array($uncat)
        );
      $loop = new WP_Query( $args );
      while ($loop->have_posts() ) : $loop->the_post();
      ?>
      <div class="col-md-12 col-sm-12 col-xs-12" style="padding-left:0; padding-right:0;">
        <a href="<?php echo get_permalink(); ?>">
        <div class="postsize">
          <div class="leftfloat" style="float: left; padding-right:20px;">
            <?php echo get_the_post_thumbnail( $page->ID, 'categoryimage', array('class' => 'faqposts')); ?>

          </div>
          <div class="contentfaq">
          <h3><?php the_title(); ?></h3>
          <span class="entry-date-orange"><strong><?php echo get_the_date(); ?></strong></span>
          <?php
          foreach((get_the_category()) as $category) { 
            echo ' | ' . $category->cat_name; 
          } 
          ?>

          <p style="margin-top:10px";><?php the_excerpt(); ?></p>
        </div>
        </div>
      </a>
      </div>

    <?php endwhile; ?>
    <?php wp_reset_query(); ?> 

is there a way, to use this code below, to ONLY get items from the taxonomy 'sectors'?

Answer 1

For this to work, you will need to get all the terms belonging to your taxonomy, and then use a tax_query to query the correct posts. For effeciency, we will only get the term ids and not the complete objects

(NOTE: The code is untested and requires PHP 5.4+. Also, just confirm the taxonomy name)

$term_ids = get_terms( 'SectorCategories', ['fields' => 'ids'] );
if ( get_query_var( 'paged' ) ) {
    $paged = get_query_var( 'paged' );
} elseif ( get_query_var( 'page' ) ) {
    $paged = get_query_var( 'page' );
} else { 
    $paged = 1;
}
$args = [
    'post_type' => 'sectors',
    'posts_per_page' => 5,
    'paged' => $paged,
    'tax_query' => [
        [
            'taxonomy' => 'SectorCategories',
            'terms' => $term_ids,
        ]
    ],
    // REST OF YOUR ARGUMENTS
];
$loop = new WP_Query( $args );

EDIT

For older PHP versions, use the following code

$term_ids = get_terms( 'SectorCategories', array( 'fields' => 'ids' ) );
if ( get_query_var( 'paged' ) ) {
    $paged = get_query_var( 'paged' );
} elseif ( get_query_var( 'page' ) ) {
    $paged = get_query_var( 'page' );
} else { 
    $paged = 1;
}
$args = array(
    'post_type' => 'sectors',
    'posts_per_page' => 5,
    'paged' => $paged,
    'tax_query' => array(
        array(
            'taxonomy' => 'SectorCategories',
            'terms' => $term_ids,
        )
    ),
    // REST OF YOUR ARGUMENTS
);
$loop = new WP_Query( $args );

EDIT 2

A very basic loop for the above query would look something like this

if ( $loop->have_posts() ) {
    while ( $loop->have_posts() ) {
    $loop->the_post();

        the_title();

    }
    next_posts_link( 'Next posts', $loop->max_num_pages );
    previous_posts_link( 'Previous posts' );
    wp_reset_postdata();
}
