Opencart can't load Region / State dropdown

问题

I'm using opencart 1.5.5.1 with a theme (sancart) and I'm getting a very annoying bug.

In the modules checkout/cart and account/register the dropdown menu for Region/State field won't load the relative values (i guess are called zone or zone_id) and remains empty, blank.

The same function instead works well in the module checkout/checkout proceeding both as Guest or user registration.

Googleing around I've notice that is a pretty common bug with many themes, above all for those using SSH (that's not my case), but I couldn't find any real solution.

回答1:

The problem is in the URL it is trying to load:

http://www.i-tec.pro/index.php?route=account/register/zone&country_id=30

In the controller catalog/controller/account/register.php there is no such an action called zone - therefore the server returns a 404 response and no zones are loaded.

This action is not present in that controller at least from version 1.5.3 (have no access to older versions right now, will check that later) - but You are using the latest OC version.

Probably the theme is not compatible with newer versions of OC - check that with the theme creators...

EDIT: Should You wish to repair the template for Yourself, add this JavaScript code at the end of the register.tpl

$('select[name=\'country_id\']').bind('change', function() {
    $.ajax({
        url: 'index.php?route=account/register/country&country_id=' + this.value,
        dataType: 'json',
        beforeSend: function() {
            $('select[name=\'country_id\']').after('<span class="wait">&nbsp;<img src="catalog/view/theme/default/image/loading.gif" alt="" /></span>');
        },
        complete: function() {
            $('.wait').remove();
        },          
        success: function(json) {
            if (json['postcode_required'] == '1') {
                $('#postcode-required').show();
            } else {
                $('#postcode-required').hide();
            }

            html = '<option value=""><?php echo $text_select; ?></option>';

            if (json['zone'] != '') {
                for (i = 0; i < json['zone'].length; i++) {
                    html += '<option value="' + json['zone'][i]['zone_id'] + '"';

                    if (json['zone'][i]['zone_id'] == '<?php echo $zone_id; ?>') {
                        html += ' selected="selected"';
                    }

                    html += '>' + json['zone'][i]['name'] + '</option>';
                }
            } else {
                html += '<option value="0" selected="selected"><?php echo $text_none; ?></option>';
            }

            $('select[name=\'zone_id\']').html(html);
        },
        error: function(xhr, ajaxOptions, thrownError) {
            alert(thrownError + "\r\n" + xhr.statusText + "\r\n" + xhr.responseText);
        }
    });
});

$('select[name=\'country_id\']').trigger('change');

and remove any previous $('select[\'name=country_id\']').change(...); calls.

change the javascript code from catalog/view/theme/YOUR THEME/template/account/register.tpl to this code here

<script type="text/javascript"><!--
$('select[name=\'country_id\']').bind('change', function() {
    $.ajax({
        url: 'index.php?route=account/register/country&country_id=' + this.value,

        beforeSend: function() {
            $('select[name=\'country_id\']').after('<span class="wait">&nbsp;<img src="catalog/view/theme/default/image/loading.gif" alt="" /></span>');
        },
        complete: function() {
            $('.wait').remove();
        },          
        success: function(json) {
            if (json['postcode_required'] == '1') {
