Array of values for custom fields

[zisis19]

Hello. I am using the Ajax Search Pro Plugin to generate a kind of filterable isotoped layout structure of a custom post type I created. All works well and I am custom fields (which I generated with the acf Plugin) to filter the search results which I’ve set to appear on default when the page loads.
Now, I have some posts of this custom post type, that belong to more than two values for the one of the custom fields.. What I mean.
Let’s say, my custom field is called “Category”. Some posts belong to the “cat-1” and others to “cat-2” and some to both of them…
So, when the user clicks on the button “cat-1” that is generated by the plugin (it is originally a checkbox, I know, but I styled it to look like a button), the posts that belong to this category appear, and the ones from “cat-2” dissappear.
How can I set some posts to belong to both of these “cat-1” and “cat-2” values? I don’t think it is as simple as to write in the field of the custom field just “cat-1 cat-2” …. I think this will just generate an extra filter button..
I hope I made my issue understandable.

Hope to hear from you soon

Hi,

Well, with simple custom fields that does not seem to be possible. You should try ACF, that supports some data structures, such as checkboxes etc.. that allows multiple values within one field. The search also supports those, so no duplicate values are displayed when using them.
