How can I assign post a specific ID on creation?
Yes, use the “import_id” field in the post, when calling wp_insert_post. This is treated as a “suggested” ID for the post that will be used if no post with that ID already exists. $post = array( ‘post_title’=>’whatever’, ‘post_content’=>’whatever’, ‘import_id’=>123 ); wp_insert_post($post);
