Ah
I can see what the issue is.
For price
you have set this to a meta key called meta_key
but it should be ldscf_trip_price
The problem is that the plugin you are using is not storing the meta data as separate keys, but as an array of many keys all inside a key called ldscf_options
. This means our plugin cannot index that data, and therefore it cannot search it.
You also have a second field labeled Departure Date
with its meta key set to __defaults_set
. Again this is the wrong key, but I cannot see any keys in the post data that would match to this. That means that the trips have no date data which can be searched at this time.
