Hi,
If you use the Shortcode interface of Vik Rent Car, you will not have to manually fill or guess the category ID you want to force. Also, that’s an ID, not a name.
You can easily identify the ID of the category from the back-end. Just click the name of an existing category to access its editing page, and if you pay attention to the URL, the number next to &cid[]= will be the ID of the category.
However, as we said, it is wrong to manually fill or guess the ID of a category in Vik Rent Car, because you need to have a Shortcode with that exact signature/code saved in Vik Rent Car, in order for our plugin to detect when you use it inside a WordPress page/post.
We strongly recommend to create an apposite Shortcode from Vik Rent Car by selecting the category you want to force. This will save a Shortcode record with a signature/code that indicates the actual ID for the attribute “category_id”. At this point you can let our plugin create a page/post that contains that Shortcode, or you can copy it and paste it manually inside the content of a page. This way the shortcode in Vik Rent Car will become connected to a WordPress page/post ID, and all routing functions will work properly.
We hope this helps!
