I think you misunderstood what I meant....
I know ACF doesn't store meta fields properly, so I want to take the options I inputted in ACF, then enter these in the Meta box.
My checkbox is not a taxonomy, just a big selection of checkboxes made with ACF (about 50).
I created a function to hook into uwpqsf_result_tempt.
If I understand correctly $results are the actual search results.
What is the difference between $arg and $getdata ?
I noticed I do find my checkbox values in $getdata but not in $arg.
So I want to read these values before $wp_query is 'filled' on line 59,
so I can create a new WP_Query with these values.
I added a meta field called dvp_services, which is an ACF checkbox.
I then didn't generate the ACF values but added 3 values which I know were used.
I added this as > value1::value1|value2::value2|value3::value3
I tested this with ajax and without ajax.
If I dump $arg with ajax, the meta field is not recognised but if I use the normal search I can see the meta term as last variable in the URL.
So I search for just 1 searchbox, I get one error (which I had expected), but when I change $arg to $new_args to use the new values, it also gives me an error and I didn't expect that. Can you elaborate a bit more ?
