WordPress wp_insert_post not inserting tags

Question

I am trying to insert a post with this code:

$my_post = array(
                'post_type'    => "essays",
                'post_title'    => 'TEST 3',
                //'post_content'  => $content,
                'post_status'   => 'draft',
                'post_author'   => 1,
                //'post_category' => $cat,
                'tags_input'    => 'TQM,tag',
        );

$post_id = wp_insert_post($my_post);

Everythings works ok except the tags, it does not insert any of them. Any idea?

Answer 1

Use the wp_set_object_terms() function:

wp_set_object_terms($post_id , $arrayoftags, $name_of_tag_taxonomy, false);

Good luck

Answer 2

Your post type is essays. Custom post types do not support tags by default. You'll have to add a tags taxonomy to them.
