WooCommerce uses select2 in the shipping and billing address field for state and country. I want to make it so that when you search for ka the top result is Kansas not Alaska.

I checked the documentation for select2 and found this:

https://select2.org/searching#customizing-how-results-are-matched

But that solution is for when there are children. I don't know how to edit the documented example to make it work with WooCommerce. Another SO article suggests this:

function matchCustom(term, text) {
  console.log('matcher is running');
  if (text.toUpperCase().indexOf(term.toUpperCase()) == 0) {
    return true;
  }
}
jQuery( document ).ready(function() {

  $(".state_select").select2({
    matcher: matchCustom
  });
});

With the above code, when I search for ka the top result is Alaska not Kansas.

I looked at the following SO questions:

jquery select2 plugin how to match only beginning of word

jquery select2 plugin how to get only the result 'myString%'

select2 search - match only words that start with search term

You can do it like so:

  1. The script file (I named it my-wc-country-select.js):

    jQuery( function( $ ){
    if ( ! $().selectWoo ) {
        return;
    }

    // Based on <https://select2.org/searching#customizing-how-results-are-matched>
    function matchCustom(params, data) {
        // If there are no search terms, return all of the data
        if ($.trim(params.term) === '') {
            return data;
        }

        // Do not display the item if there is no 'text' property
        if (typeof data.text === 'undefined') {
            return null;
        }

        // `params.term` should be the term that is used for searching
        // `data.text` is the text that is displayed for the data object
        var s = $.trim( params.term ).toLowerCase();
        var s2 = $.trim( data.text ).toLowerCase();
        if ( s === s2.substr( 0, s.length ) ) {
            return data;
        }

        // Return `null` if the term should not be displayed
        return null;
    }

    function country_select_select2() {
        // Apply the custom "matcher" to the country and state drop-downs.
        $( 'select.country_select:visible, select.state_select:visible' ).selectWoo( {
            // We're just changing this option.
            matcher: matchCustom
        } );
    }

    country_select_select2();

    $( document.body ).bind( 'country_to_state_changed', function() {
        country_select_select2();
    });
} );

    Reference

  2. Load the file on the front-end: (this code would go in the theme functions file)

    wp_enqueue_script( 'my-wc-country-select', 'path/to/my-wc-country-select.js', [ 'wc-country-select' ] );

    Make sure wc-country-select is added as a dependency.
