Retrieve selected values to count and display, from select.

  • Hi! I have a dropdown select with some countries in a custom post type. You can choose 1 value. I want to create a comma-separated list with all values chosen in all posts, once. Non-chosen values are not displayed. So the script should echo:

    France, Japan, Maroc, Australia

    And for the same list, I want to have the number of different countries chosen. So in the example above the output now should be 4.

    So I can create something on home like: We have 4 countries selected: France, Japan, Maroc, Australia.

    ACF and these functions are new to me. I get things working as long it’s not select/checkbox/radio. So in this case… I’m stuck.

    Hope you can help, best regards

  • To do this you would have to query all post and loop over them and get the value from each post. There isn’t a simple way to get a list of any ACF field value for every post.
