如何在opencart中显示国家和地区？
我在 OpenCart 的管理部分创建了一个注册页面，我们在其中询问详细信息，例如姓名，电子邮件，电话，国家/地区，州/区域，密码等等。除了国家/地区和区域表单字段外，一切正常。每当我打开表单时，我发现一个国家总是被选中，区域字段中没有显示任何内容。这是第一个问题。当我选择另一个国家/地区时，它会加载州/区域，如果一切顺利，那么用户就会注册。但是如果表单中有任何错误，那么当它在页面上显示错误时，状态/区域值会再次丢失。我必须重新选择国家，然后显示区域。我已通过“echo”检查了区域的值是否已转移到此页面但未在下拉列表中显示。这是我的主要问题。
这是第一张图片的链接 -
现在这是显示错误消息的第二个图像---
现在请有人告诉我该怎么办？ 我不是opencart的专家。我刚刚创造了这个。我也不了解jquery或javascript。 请告诉我应该把这部分代码放在这里以获得解决方案。
谢谢!!

我刚刚在模板文件中进行了两项更改 - 1. HTML部分 2. Ajax脚本
-
HTML部分是 -
<tr> <td><span class="required">*</span> <?php echo $entry_country; ?></td> <td><select name="country_id"> <option value=""><?php echo $text_select; ?></option> <?php foreach ($countries as $country) { ?> <?php if ($country['country_id'] == $country_id) { ?> <option value="<?php echo $country['country_id']; ?>" selected="selected"><?php echo $country['name']; ?></option> <?php } else { ?> <option value="<?php echo $country['country_id']; ?>"><?php echo $country['name']; ?></option> <?php } ?> <?php } ?> </select> <?php if ($error_country) { ?> <span class="error"><?php echo $error_country; ?></span> <?php } ?> </td> </tr> <tr> <td><span class="required">*</span> <?php echo $entry_zone; ?></td> <td><select name="zone_id"> <option value=""><?php echo $text_select; ?></option> </select> <?php if ($error_zone) { ?> <span class="error"><?php echo $error_zone; ?></span> <?php } ?></td> </tr> -
Ajax部分是 -
<script type="text/javascript"> $('select[name=\'country_id\']').bind('change', function() { $.ajax({ url: 'index.php?route=seller/customer/country&token=<?php echo $token; ?>&country_id=' + this.value, dataType: 'json', beforeSend: function() { $('select[name=\'country_id\']').after('<span class="wait"> <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'); </script>

在getForm()函数中找到以下行：
if (isset($this->request->post['business_id'])) {
$this->data['business_id'] = $this->request->post['business_id'];
} elseif (isset($this->session->data['business_id'])) {
$this->data['business_id'] = $this->session->data['business_id'];
} else {
$this->data['business_id'] = $this->config->get('business_id');
}
// few lines later
if (isset($this->request->post['country_id'])) {
$this->data['country_id'] = $this->request->post['country_id'];
} elseif (isset($this->session->data['country_id'])) {
$this->data['country_id'] = $this->session->data['country_id'];
} else {
$this->data['country_id'] = '';
}
if (isset($this->request->post['zone_id'])) {
$this->data['zone_id'] = $this->request->post['zone_id'];
} elseif (isset($this->session->data['zone_id'])) {
$this->data['zone_id'] = $this->session->data['zone_id'];
} else {
$this->data['zone_id'] = '';
}
并将其更改为
if (isset($this->request->post['business_id'])) {
$this->data['business_id'] = $this->request->post['business_id'];
} else {
$this->data['business_id'] = $this->config->get('business_id');
}
if (isset($this->request->post['country_id'])) {
$this->data['country_id'] = $this->request->post['country_id'];
} else {
$this->data['country_id'] = '';
}
if (isset($this->request->post['zone_id'])) {
$this->data['zone_id'] = $this->request->post['zone_id'];
} else {
$this->data['zone_id'] = '';
}
你在这里没有使用会话，但可能会发生具体的值可能会在其他形式的会话中，这可能会搞砸。
