Hi, I need to know how to get the values of the fields "Place of destination" and "Pick-up place" in the search of vehicles. With those values: if a round trip was chosen, we could put the value of "pick-up place" (on the way), in "place of destination" (in return)
That is something you would have to customize.
You will find the seach widget is in wp-content/plugins/transfers-plugin/includes/widgets folder.
The search page is found in the theme folder. The file is called page-advanced-search.php
