如何在CodeIgniter中的控制器中获取选择框的选项值

Question

I have a controller with the index function() and I would like to get the selected value of the option value of the view in the controller index() .

public function index() {
    $this->accesscontrol->can_or_redirect('view', 'translation');
    $this->output->view('translation/language');
}

My view is as follows:

<select name="lang_choice1" id="lang_choice1">
    <?php
    $path = './application/language/';
    $dir = new DirectoryIterator($path);
    foreach ($dir as $fileinfo) {
        if ($fileinfo->isDir() && !$fileinfo->isDot()) {
            echo "<option value='" . $fileinfo->getFilename() . "'>".$fileinfo->getFilename()."</option>";
        }
    }
    ?>
</select>

Answer 1

创建一个带有方法post的表单标签，并为控制器设置操作URL，还创建一个类型为Submit的按钮，以便在提交表单时可以在控制器中获取选定的值

Answer 2

If you need return any value back to CONTROLLER from VIEW .

Your need to pass all those values to url via GET or POST request and you can get all the values through uri segments.
