    I found this script to functions

    function wpse_248054(){
    $custom_field_name = 'Genre';
    $posts = new WP_Query(
        array(
            'posts_per_page' => -1,
            'post_type'=> 'post',
        )   
    );
    foreach($posts->posts as $post){
        $meta = get_post_meta($post->ID, 'Genre', true);
        if(! empty( $meta )){
            $term_id = wp_create_category($meta, 3); // 2nd argument, parent id (optional)
            $new_post_cat = wp_set_post_terms( $post->ID, $term_id, 'category', true );
        }
    }
}
add_action('admin_init', 'wpse_248054');

    this auto add custom field to category, the problem is the meta key have a multiple values, like : Action, Drama, War
    and this script don’t separate values with comma and creat a category “Action, Drama, War” all together. who can i separate values ?

    Use the PHP function “explode” to separate a comma delimited string.

    The function returns an array of strings given a comma separated string. You can either walk through the array and create categories for each or pick the zeroth element.

    But since you don’t understand PHP, let’s start by asking this: What are you trying to accomplish? Use words, not code.

    So, omdbapi generate information about movies to meta keys.
    Like, year, actors, director, genre…

    i wish filed “Genre” auto add to categories.
    example:

    You’re adding categories? Or are you adding custom fields to categories? What is “omdbapi”

    It looks like you’ve created custom post types. Am I correct? Are you using ADvanced Custom Fields or something like that?

    No, is a theme with omdbapi generator (imdb/themoviedb informations).
    They create all meta keys automatic but dont add genres to categories, i put manual.

    I guess I don’t understand what you mean by “add genres to categories”. Are genres child categories?

    Then why are you adding meta fields rather than adding the post(s) to a category?
