while ( $loop->have_posts() ) {
    $loop->the_post();
    ?>
    <div class="entry-content">
        <?php the_title(); ?>
        <?php the_content(); ?>
    </div>
    <?php
}

        'post_status' => 'publish',
        'posts_per_page' => 5,  
        
		);
	
    $loop = new WP_Query( $args ); 
        
    while ( $loop->have_posts() ) : $loop->the_post(); 
        the_title(); 
	the_excerpt();

Example 4: how to store a single posttype in a plugin

/* Filter the single_template with our custom function*/
add_filter('single_template', 'my_custom_template');

function my_custom_template($single) {

    global $post;

    /* Checks for single template by post type */
    if ( $post->post_type == 'POST TYPE NAME' ) {
        if ( file_exists( PLUGIN_PATH . '/Custom_File.php' ) ) {
            return PLUGIN_PATH . '/Custom_File.php';
        }
    }

    return $single;
