This may require a bit more work to replace the currency in all locations, and there may be some limitations.

Thanks Andrew.
Do you see any way to change the currency globally via a switcher?

Following on from this, this would be great if a switcher was an option in the future

Dear Team,

Please, I just need two forms of currency (NGN and USD) option for members to select from. How can this be implemented using the above script?

Is the modification below work?
global $level_currencies;
$level_currencies = array(
5 => array("NGN", "&naira;"),
6 => array("USD", "$")

Thank you.

instead of this solution I prefer the way woocommerce switcher works it makes currency exchange rate more easy e.g., I have one level called 16 would make same level of setting currencies

though this is not complete tested code this way we don't have to manage new level as customization with level id might be there in pmpro customization plugin

You can also try this plugin (maintained by a developer outside of PMPro) -> https://wordpress.org/plugins/pmpro-multiple-currencies/

this plugin also have same issue we need to create new level the solution which i gave is more wise then creating new level the whole idea is to maintain different price as per the currency at same level id

@andrewlimaza whole idea here is if the geo location is Nigeria then charge as per Naira and if the geo location is Liverpool suppose then charge as GBP

I can improvise it further once my all test goes perfect @andrewlimaza but solution that you gave is not much helpful
