How to get all posts assigned to a taxonomy term only?

Question

I have a taxonomy called projects and it has 4 types of projects. Assume new, current, past, future.

In taxonomy-projects.php page I need to show selected taxonomy term posts only. Assume I selected future category. Then I need to show all posts under future.

Here what I have tried so far. But it is returning all the created taxonomies under proejcts taxonomy and all posts assigned to those created taxonomies.

$projects = get_terms('projects');

foreach($projects as $project) {
    wp_reset_query();
    $args = array('post_type' => 'project',
        'tax_query' => array(
            array(
                'taxonomy' => 'projects',
                'field' => 'slug',
                'terms' => $project->slug,
            ),
        ),
     );

     $loop = new WP_Query($args);
     if($loop->have_posts()) {

        echo '<h2>'.$project->name.'</h2>';

        while($loop->have_posts()) : $loop->the_post();
            echo '<a href="'.get_permalink().'">'.get_the_title().'</a><br>';
        endwhile;

     }
}

Well, you can do it in many ways. You can introduce a form with a drop down input for the terms and pass it to a function through POST or GET method and the query the posts associated with the terms, then show them. Fro capturing the send data you can use admin_post_{$action}. Read thoroughly the documentation and do some search, you'll get necessary information to make this thing work.

You can use AJAX to make this thing more robust. For AJAXifing the system you can have a look at those below links-

2. https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_(action)
3. https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_nopriv_(action)

From your question this is the only thing right now I can suggest.

Hope those helps.
