缺少wp_insert_term（）的参数4

I am trying to create category from WordPress plugin. Here is my code:

$id = wp_create_category('Category_name', 2);

But i am getting this error:

Missing argument 4 for wp_insert_term(), called in taxonomy.php on line 144 and defined in taxonomy.php on line 2226

But i am not using function wp_insert_term() anywhere. Please help me. What i am doing wrong? is there anything extra which i have to do in plugin to make it working?

Thanks in advance

try to use wp_insert_category as wp_create_category is just a wrapper for it.

1. Passing a category ID means you're trying to create a child category, so make sure that a category with and ID of 2 exists.

2. If you do have a category with an ID of 2, try omitting that param and seeing what happens. If your still getting an error after that, check what version of PHP you are using and update it.

3. If you're making a plugin to add a category to the database you will be better off using wp_insert_category() as it gives you more control.
