Need to link three user meta fields

[smithandjones]

I have three custom user meta fields which control currency display and currency conversion on my site.

‘buyer_default_currency_select’
‘buyer_default_currency_code’
‘buyer_default_currency_symbol’

‘buyer_default_currency_select’ appears on a front end user profile form. The user can select from a drop down. So e.g. the user can select between;

‘British Pound Sterling (£)’
‘US Dollar ($)’
‘Euro (€)’

I need to find an action hook which updates the other two fields appropriately. So e.g. if the user selects;

‘buyer_default_currency_select’ = British Pound Sterling (£)

Then;

‘buyer_default_currency_code’ should be updated with ‘GBP’
‘buyer_default_currency_symbol’ should be updated with ‘£’

Could you help me with a function to achieve this please.

regards

Robert

Hello,
These codes might be helpful for you:

add_action( 'user_meta_after_user_update', 'updateCurrency' );
function updateCurrency( $response ) {
    $userID = $response->ID;
    $currencySelect = get_user_meta( $userID, 'buyer_default_currency_select', true );
    if ( empty( $currencySelect ) ) return;
    
    switch( $currencySelect ) {
        case 'pound' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'GBP' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '£' );
        break;
        case 'dollar' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'USD' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '$' );
        break;
        case 'euro' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'Euro' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '€' );
        break;
    }
}

Assume value of buyer_default_currency_select are pound, dollar or euro.

Thanks.

Hi Khaled

Could I check one more point with this code please.

I used code based on your suggestion as follows;

add_action( 'user_meta_after_user_update', 'user_meta_after_user_update_function' );
function user_meta_after_user_update_function( $response ){

$userID = $response->ID;
    $BuyerCurrencySelect = get_user_meta( $userID, 'buyer_default_currency_select', true );
    if ( empty( $BuyerCurrencySelect ) ) return;
    switch( $BuyerCurrencySelect ) {
        case 'British Pound Sterling (£)' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'GBP' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '£' );
        break;
        case 'US Dollar ($)' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'USD' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '$' );
        break;
        case 'Euro (€)' :
            update_user_meta( $userID, 'buyer_default_currency_code', 'EUR' );
            update_user_meta( $userID, 'buyer_default_currency_symbol', '€' );
        break;
    }

The code above works fine.

So I wanted to do the same for the seller profile. I used the following code within the same function;

$userID = $response->ID;
    $SellerCurrencySelect = get_user_meta( $userID, 'seller_listing_currency_select', true );
    if ( empty( $SellerCurrencySelect ) ) return;
    switch( $SellerCurrencySelect ) {
        case 'British Pound Sterling (£)' :
            update_user_meta( $userID, 'seller_default_currency_code', 'GBP' );
            update_user_meta( $userID, 'seller_default_currency_symbol', '£' );
        break;
        case 'US Dollar ($)' :
            update_user_meta( $userID, 'seller_default_currency_code', 'USD' );
            update_user_meta( $userID, 'seller_default_currency_symbol', '$' );
        break;
        case 'Euro (€)' :
            update_user_meta( $userID, 'seller_default_currency_code', 'EUR' );
            update_user_meta( $userID, 'seller_default_currency_symbol', '€' );
        break;
    }

This second code did not work.

So I experimented and changed one line from;

 $SellerCurrencySelect = get_user_meta( $userID, 'seller_listing_currency_select', true );

to;

 $SellerCurrencySelect = get_user_meta( $userID, 'seller_listing_currency', true );

Have you any idea why the second use of the same function was failing until I removed the ‘select’ term? Both variables are select types.

Regards

Robert
