Post added via wp_insert_post with category doesn’t show in category listing

I’ve created a plugin that auto creates a post and attaches a category to it, which is then hidden from the main blog and only shows in the category listing…

I can successfully add a new post via wp_insert_post with all the correct params and once the post_id is returned I’m calling wp_set_object_terms with the category I want that post to be included under.

I can confirm that the post is created, and the post has the correct category. However, if I visit the category listing for that particular cat, I see all the previous posts but not the dynamically created one. If I manually add a new post and select the same category, it does display in the list.

I haven’t found anything regarding why this is happening… Has anyone else run into this issue? Everything seems to be working fine, except with the category listing…

(Edited to add code sample)

    $new_post = array(
    'post_title' => $postTitle,
    'post_content' => '$postContent,
    'post_status' => 'publish',
    'post_date' => date('Y-m-d H:i:s'),
    'post_author' => $current_user->ID,
    'post_type' => 'post'
);

$post_id = wp_insert_post($new_post);

wp_set_object_terms($post_id, array(24), 'category');

I think you have a typo mistake there line 3.

the code could be like this

    'post_content' => $postContent,
