[Resolved] How to change currecy using a url parameter

Hi.

I have the solution for how you can change the currency using a URL parameter.
Here are two options that you can use.

1. This first option is according to the example that we give in our wcml_client_currency hook here https://wpml.org/wcml-hook/wcml_client_currency/

A. Add the following code to the functions.php file of your theme.

/**
 * Add this code to the functions.php file of your theme.
 */
add_filter( 'wcml_client_currency', 'modify_client_currency', 10, 1 );
 
function modify_client_currency( $currency ) {
    if ( is_shop() ) { 
        return 'USD'; // If this is a shop page, change the front-end currency to USD 
    } else {
        return $currency;
    }
}

In this example, every time you visit the shop page of the site you will see the currency in USD. You can, of course, change the currency and the page in the function.

2. I also checked the other example from the ticket in which you shared the link with me.

https://wpml.org/forums/topic/can-i-make-the-website-display-in-a-certain-currency-via-url/#post-4264655

If you add this code then you can change the currency using a URL parameter.

add_filter( 'wcml_client_currency', 'modify_client_currency', 10, 1 );
 
function modify_client_currency( $current_currency ) {
    if( !is_admin() ){
        global $woocommerce;
 
        $currency = isset( $_GET['currency'] ) ? esc_attr( $_GET['currency'] ) : $current_currency;
        $currency = strtoupper( $currency );
 
        $woocommerce->session->set('client_currency', $currency);
 
        return $currency;
      }
}

For example, if the currency is USD and you add the parameter like this then it would change into EUR.
your-domain.com/?currency=EUR

Please let me know if this information is helpful to you.

Hi.

You wrote: "it was change successfully but after few sec it is change to default forced location currency using ajax. "

I was not able to replicate this problem on your site. When I force with the URL parameter to change the currency it stays like that even if I wait for a few minutes. Please see the attached screenshot.

Can you please give me the exact steps on how to replicate and see this issue on your site?

You wrote: "I am thinking "Store a language cookie to support language filtering for AJAX " cookies not stored by wcml_client_currency i feel.."

I'm not sure that this is the case. I say it because even on my local test site I was not able to replicate this problem.

You might find one of the following hooks that can are related to Ajax and currency helpful in your case.

If you need more help from us, could you please share your Debug information with me?
You can read a detailed explanation about it here.

The debug info will give me a lot of information about how your site is configured and will help me understand the source of the problem.

Thanks,

Hi.

I'm sorry, but the video is very shaky and gets out of focus.
It is hard for me to follow and understand what is wrong there.

But watching the video, I think that I've just realized that you are talking about an option to switch currencies. I'm talking about the option that you show in the video which comes up as a pop-up window. Please see the attached screenshot.

All the time I thought that you have some problem with the wcml_client_currency hook and the currency URL parameter.

So for me to help you better, I must understand the problem correctly.
If indeed, the problem is with the pop-up currency switcher, then please tell me what created this feature?
I ask this because this is not a feature that is built-in in WooCommerce Multilingual.
Is this the currency pop-up feature possible by another WooCommerce plugin that you added or maybe the theme that you are using?

I'll be available today until 4:15 pm GMT+3 time zone. If you want to chat, please open a chat in our forum and ask for me.

Thanks,
Itamar.

Hi and thanks for the extra details.

I can see now this issue on your site.

First please check that it is not a caching issue by clearing all the cache on your site and deactivating all the caching plugins. If oyu have caching also on the server please also deactivate it.

If the problem persist even when all the caching is deactivate them, I suspect that there is a collision with the theme or another plugin that might cause this problem. If possible get your site into a minimum environment. Minimum environment means switching to a default WordPress theme like Twentytwenty and no plugins activated except WPML.

You will need first to check if the problem persists when just the theme is switched to Twentytwenty (for example). If it persists then deactivate all plugins except the WPML and its add-ons and WooCommerce itself (without any of its add-ons). Then please check if the problem persists. If it does not persist so start by activating the plugins one by one and check when the problem comes back, then report to me which was the culprit plugin.

**** Important! Please make a full site backup (files and DB) before you proceed with those steps****


*** If your site is a live site you might want first to try those procedures in a staging environment or a snapshot of your site on your local server or another server. ***

Thanks,
Itamar.
