foreach问题选择表单

我的代码点火器项目遇到了麻烦。

我可以通过设置中的选择表单将我的主题/模板更新到数据库。我可以做得很好，主题/模板在选择表单中显示得很好。

但是$templates == $config_template没有显示所选的当前主题/模板。

我不确定该为控制器部分和模型添加什么，以使其能够将数据库中的当前主题/模板显示为第一个

以下是我迄今为止所做的工作。

控制器

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Settings extends MX_Controller {
   public function index() {
    $this->document->setTitle($this->lang->line('heading_title'));
        $data['action'] = site_url('admin/settings');
        $data['logout'] = site_url('admin/logout');
        $data['home'] = site_url('admin/dashboard');
        $data['cancel'] = site_url('admin/dashboard');
        $this->load->model('admin/setting/model_setting_store');
        $this->model_setting_store->config_template();
        $data['templates'] = array();
        $directories = glob(APPPATH . 'modules/catalog/views/theme/*', GLOB_ONLYDIR);
        foreach ($directories as $directory) {
            $data['templates'][] = basename($directory);
        }

        $this->load->library('form_validation');
        $this->form_validation->set_rules('config_meta_title', 'Website Title');
        $this->form_validation->set_rules('config_meta_description', 'Description');
        $this->form_validation->set_rules('config_meta_keyword', 'Keywords');
        $this->form_validation->set_rules('config_template', 'Template');
    if ($this->form_validation->run() == FALSE) {
        return $this->load->view('setting/settings', $data);
    } else {
        redirect('admin/dashboard');
    }
   }
}

型号

<?php
class Model_setting_store extends CI_Model {
    function config_template() {
        $data = array(
            'setting_id' => "10",
            'website_id' => "0",
            'group' => "config",
            'key' => "config_template",
            'value' => $this->input->post('config_template')
        );
        $this->db->update('setting', $data);
    }
}
