如何在WordPress中将JSON放入自定义字段和自定义分类中？

Question

我没有找到任何解决方案来以自定义帖子类型将json数据导入自定义字段和自定义分类法。这是我的代码，用于导入json以使用此脚本制作wordpress自定义帖子。

$json = "http://tropiktv.ba/filmovi/raspored.json";
$response = file_get_contents($json);
$mydecode = json_decode($response);

for ($i = 0; $i < 1; $i++) {
    $title = str_replace("&amp;", "&", $mydecode[$i]->Naziv);
    $description = str_replace("&amp;", "&", $mydecode[$i]->Opis);
    $coupon_type = 'filmovi';
    $link = $mydecode[$i]->link;
    $zanr = $mydecode[$i]->Žanr;
    if( $coupon_type === "filmovi" ) {
        // Check if already exists
        $get_page = get_page_by_title( $title );
        if ($get_page == NULL){
            // Insert post
            $new_post = array(
                'post_title' => $title,
                'post_content' => $description,
                'post_status' => 'publish',
                'post_author' => 1,
                'post_type' => 'filmovi'
            );
            // Insert post
            $post_id = wp_insert_post($new_post);
            // Insert post meta if available  
            update_post_meta( $post_id, 'opis', $description );  
            update_post_meta( $post_id, 'link', $link );
            update_post_meta( $post_id, 'inline_featured_image', 'http://tropiktv.ba/wp-content/uploads/mala-princeza.jpg' );



            // Uncomment to check if meta key is added
            // $get_meta_value = get_post_meta( $post_id, 'meta_key', true );        
            // echo "<pre>";
            // print_r($get_meta_value);
        }
    }else{
        // Update meta value
        update_post_meta($get_page->ID, 'my_key', 'meta_value');

        // Uncomment to check if meta key is added
        // $get_meta_value = get_post_meta( $get_page->ID, 'meta_key', true );        
        // echo "<pre>";
        // print_r($get_meta_value);
    }
}
