display content using get posts from terms under a custom taxonomy

Question

I am having a custom taxonomy say "project-type" which is registered for the custom post "projects" and under that I have terms "catOne" and "catTwo". Now I want to display all the custom posts that are linked to catOne using the term_id of "catOne", which in my case is 9.

So I am successfully able to loop through all the posts but it is displaying only the ID but not all contents.

My approach:

$cat_id = 9;

$args = array(
    'post_type' => 'projects',
    'tax_query' => array(
        array(
            'taxonomy' => 'project-type',
            'field'    => 'term_id',
            'terms'    => array( $cat_id )
        ),
    ),
);

    $posts = get_posts( $args );

    foreach ( $posts as $post ) {
    setup_postdata( $post ); ?>

    <div id="post-<?php echo $post->ID; ?> <?php post_class(); ?>">
        <h1 class="posttitle"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>

        <div id="post-content">
        <?php the_excerpt(); ?>
        </div>

   </div>

   <?php } wp_reset_postdata();

Output I am getting

<div id="post-137 class=" ""="">
        <h1 class="posttitle"><a href=""></a></h1>
        <div id="post-content">
                </div>
   </div>
    <div id="post-135 class=" ""="">
        <h1 class="posttitle"><a href=""></a></h1>
        <div id="post-content">
                </div>
   </div>

Can someone please help me with where I am going wrong?

Instead of using post_class() , the_permalink() , the_title() , and the_excerpt() , you should use the $post object to get the data, just like you did with $post->ID . The functions you've used should be called only if you're using a loop based on have_posts() . You aren't, so replace them with:

• post_class() -> get_post_class( '', $post->ID )
• the_permalink() -> get_the_permalink( $post->ID )
• the_title() -> $post->title
• the_excerpt() -> $post->post_excerpt
