Hi Mintu,
I’m sorry about your frustration here. I dug deeper into the actual Events Calendar code and indeed found that we have the value for “Vietnam” hard-coded in our plugin as “Viet Nam”.
I’m curious about your input issues though – if importing things with “Vietnam” as the country leads to the saved Venue country being empty, would you be willing to make a small code change to test if this is the full extent of the issue?
To make the change I’m describing here, you’d need to head into your plugin files and head to a file called /lib/tribe-view-helpers.php and look for line 278 or so of the file – you should see code that looks like this:
"VN" => __( "Viet Nam", 'tribe-events-calendar' )
If you change that to this:
"VN" => __( "Vietnam", 'tribe-events-calendar' )
And then run your import of events and venues again, does anything improve? Do your imported venues save with their countries properly set to “Vietnam”?
Let us know if this helps Mintu! 🙂
Cheers,
George
