Hello,

Currently it is not possible to disable validation. I have added this option in the upcoming major release.

As a temporary measure, for now, you can do the following:

1. Delete the minified javascript file: wallets-fiat-0.6.3-beta.min.js. This will cause the plugin to fall back to using the unminified version, wallets-fiat.js

2. Edit the wallets-fiat.js file as needed to conform to your validation requirements, if any.

If you change line 116 from:

return val && IBAN.isValid( val ); // check not empty, and valid iban format

to
return val.match( /^\d{9,}$/ );

then this will disable IBAN validation, and will check if the value has at least 9 digits

That’s it! (You can optionally minify the file if you want, but it’s not necessary.)

As a sidenote, if you need to modify the error message for this field, use the wallets_fiat_ui_text_iban_invalid filter, like so:

add_filter( 'wallets_fiat_ui_text_iban_invalid', function( $text ) {
	return 'The number must be at least 9 digits long';
} );

And if you need to modify the name of the field (IBAN), you can do so with the wallets_fiat_ui_text_iban filter:

add_filter( 'wallets_fiat_ui_text_iban', function( $text ) {
	return 'Foo';
} );

Finally, if you need to modify the name of the option:

add_filter( 'wallets_ui_text_swiftbiciban', function( $text ) {
	return 'Other option';
} );

Please let me know if you have any questions.

with regards
