Home Forums Backend Issues (wp-admin) Update value by 1 onclick Reply To: Update value by 1 onclick

  • The topic is too complex for a simple explanation or providing simple code examples. The best I can do is to give you an outline of what would be needed.

    The first thing you’ll need to do is read about AJAX in WP, the best source of information in this is here You need to create AJAX what will make a request to update the value.

    If you want to be able to reduce the value you not only need to know how many times it was clicked, you will need to record who clicked it. This will involve the user’s profile keeping track of all the posts they’ve liked and if there is not a profile it will involve cookies or some other mechanism for knowing if the person viewing the page has already liked it or not. This will all depend on how the site is set up and how visitors use the site.
