Question

我需要以提交的表单发送字段的电子邮件通知。

我的问题如下：表格中的HTML选择标记。

<select id="country_code" name="country_code">
    <option value="" selected disabled>Country</option>
    <option value="AR">Argentina</option>
    <option value="BR">Brazil</option>
    <option value="CG">Congo</option>
    <option value="ZW">Zimbabwe</option>
</select>

下面我会看到所选选项的国家/地区代码：

$country_code = $_POST["country_code"];

如何在选项标签（即国家/地区名称）中使用PHP所选值的文本？

注意：我无法使用MySQL或JavaScript，也无法更改选择框值。

PHP：

<select id="country_code" name="country_code">
    <option value="" selected disabled>Country</option>
    <option value="AR">Argentina</option>
    <option value="BR">Brazil</option>
    <option value="CG">Congo</option>
    <option value="ZW">Zimbabwe</option>
</select>

Answer 2

提交表单时更改JS中的值要么将值更改为：

<option value="CG_Congo">Congo</option>

然后使用explode或split

拆分它

$location = explode("_", $_POST["country_code"]);

或将其保存在数据库中并查询OR 使用以下翻译在代码中保存数组：

$translations = ['CG' => "Congo", etc];

然而，真的不会推荐最后一个。我不明白为什么你不会改变选项价值，因为你仍然得到国家代码，但国家名称是一个补充。

编辑：在线找到JSON国家/地区名称列表：http://country.io/names.json，你可以这样做：

$country_code_to_name = json_decode(file_get_contents("http://country.io/names.json"), true);
echo $country_code_to_name[$_POST["country_code"]];

下拉框中选项选择属性的文本
