Change Stripe currency depending on a field

Hi @fcis999,

I hope you are doing well today!

You can try to use the following code snippet as mu-plugin where?select-1?is a field for currency with?World currency code?values? (USD,?UAH?and so on)

<?php
add_filter( 'forminator_set_field_stripe-1', function( $value, $wrapper_id, $name ) {
	if ( 'currency' === $name ) {
		$currency_field = 'select-1';
		$currency       = filter_input( INPUT_POST, $currency_field );
		if ( $currency ) {
			$value = $currency;
		}
	}
	return $value;
}, 10, 3 );

You can find more information below on how to use mu-plugins.

Can you please confirm with me if I need to change anything in the code?

Like I think I need to make sure the currency dropdown list is named select-1. Anything else?

Also, after I install it, then this will affect all stripe fields in all my forms on my website? as I only want it on one of the forms.

Hi @fcis999

I hope you are doing well.

In case you have multiple select fields you can just update the:

$currency_field = 'select-1';

And then add the one that matches your field ID, it is visible when you edit the form: https://monosnap.com/file/VCvF4l5VgJgvOqY6aYiEQu5SYoWb0H

On the select make sure the value matches the currency code https://monosnap.com/file/R7l8sLU9m4NK4qXHym6tj3neW7Hifw

Also, after I install it, then this will affect all stripe fields in all my forms on my website? as I only want it on one of the forms.

This will affect all forms, but I pinged our developers to verify how we can have a limit based on Form ID.

We will keep you posted.

Hi @fcis999

An update here

You can use the following code to limit the form ID:

<?php 

add_filter( 'forminator_set_field_stripe-1', function( $value, $wrapper_id, $name ) {
	if ( 'currency' === $name ) {
		$currency_field = 'select-1';
        $form_id        = filter_input( INPUT_POST, 'form_id' );
        if ( $form_id == 6 ) { // Please change the form ID.
            $currency = filter_input( INPUT_POST, $currency_field );
            if ( $currency ) {
                $value = $currency;
            }
        }
	}
	return $value;
}, 10, 3 );

Replace the 6 with your form ID, found in the form shortcode or when editing the form at the page URL.
