How can I display all post IDs from the taxonomy?

Question

I try echo on any page (I mean page on my site) all post IDs what I have in my taxonomy.

I found this:

get a list of posts from Custom Taxonomy

But I could not handle with it.

I want to echo all currently published post IDs what the taxonomy contains.

Name taxonomy = 'agency' Post type = 'job_listing'

<input value="<?php echo $idsTaxonomy"?>

And I would see output example:

420, 16, 5

Somone could help me? Thank you for help.

Just some code to get started. This will get you all the IDs for job_listings that are assigned to term 4 in your taxonomy.

<?php
    $posts = get_posts( array(
        'posts_per_page' => -1,
        'fields' => 'ids',
        'post_type' => 'job_listing',
        'tax_query' => array(
            array(
                'taxonomy' => 'agency',
                'field' => 'term_id',
                'terms' => 4
            )
        )
    ) );

    echo implode( ', ', $posts );
?>
