[Vuejs]-Trying to Update PHP Query After Posting Data Using Axios in Vue App

Seems like you’re just not concatenating that variable into your string. All you should need to do is just use that variable in your string that you pass to your function like this:

<?php 
echo getBhQuery('search','JobOrder','isOpen:true AND region:"'. $region .'"','id,title,categories,dateAdded,externalCategoryID,employmentType,customText12'); ?>
