I have a website where members offer their services, and guests can search through these offerings.
I have a large list of 'likes' from which a seller can select up to 30. This limitation of 30 helps to avoid that sellers select all 'likes' and end up in all searches from potential buyers.
This way, the seller has to choose with which 'likes' he wants to be found on my website.
In the Meta Boxes the likes is a large set of radio boxes with label "Yes" and "No", value 1 and 0.
1. How can I add the total value of all these radio boxes, and display that on screen, as a sort of counter while selecting the 'likes'?
- How can I show an error message when there are more than 30 'likes'?
