Php 在这个Codeigniter 3应用程序中，如何将基本url传递给细枝模板？

我正在使用CodeIgniter 3.1.8和Bootstrap 4开发。我决定给它添加一些主题。该应用程序不是HMVC，而是MVC

我认为使用细枝模板引擎添加主题是个好主意。为此，我使用

主题模板的扩展名是

.twig

，而不是

.php

在Posts controller中，我为所有帖子和按作者筛选的帖子提供了以下两种方法：

很明显，我需要为模板中

的

href

属性使用基本url

在

application\config\config.php

中，我有一段代码动态获取应用程序的基本url：

$root=(isset($_SERVER['HTTPS']) ? "https://" : "http://").$_SERVER['HTTP_HOST'];
$root .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
$config['base_url'] = $root;

但我无法将其传递到小树枝模板

我该怎么做？

我找到了一个简单的解决方案：

首先，我用两种方法向

$data

数组添加了

base\u url

变量：

public function index() {

    //call initialization method
    $config = $this->_initPagination("/", $this->Posts_model->get_num_rows());

    $data = $this->Static_model->get_static_data();
    $data['base_url'] = base_url("/");
    $data['pages'] = $this->Pages_model->get_pages();
    $data['categories'] = $this->Categories_model->get_categories();  

    //use limit and offset returned by _initPaginator method
    $data['posts'] = $this->Posts_model->get_posts($config['limit'], $config['offset']);

    $this->twig->addGlobal('siteTitle', 'My Awesome Site');
    $this->twig->addGlobal('maincss', base_url('themes/caminar/assets/css/main.css'));
    $this->twig->display('themes/caminar/layout', $data);
}

public function byauthor($authorid){
    //load and configure pagination 
    $this->load->library('pagination');
    $config['base_url'] = base_url('/posts/byauthor/' . $authorid);
    $config['query_string_segment'] = 'page';
    $config['total_rows'] = $this->Posts_model->posts_by_author_count($authorid);
    $config['per_page'] = 12;
    
    if (!isset($_GET[$config['query_string_segment']]) || $_GET[$config['query_string_segment']] < 1) {
        $_GET[$config['query_string_segment']] = 1;
    }
    
    $limit = $config['per_page'];
    $offset = ($this->input->get($config['query_string_segment']) - 1) * $limit;
    $this->pagination->initialize($config);

    $data = $this->Static_model->get_static_data();
    $data['base_url'] = base_url("/");
    $data['pages'] = $this->Pages_model->get_pages();
    $data['categories'] = $this->Categories_model->get_categories(); 
    $data['posts'] = $this->Posts_model->get_posts_by_author($authorid, $limit, $offset); 
    $data['posts_count'] = $this->Posts_model->posts_by_author_count($authorid); 
    $data['posts_author'] = $this->Posts_model->posts_author($authorid);

    $this->twig->addGlobal('siteTitle', 'My Awesome Site');
    $this->twig->addGlobal('maincss', base_url('themes/caminar/assets/css/main.css'));
    $this->twig->display('themes/caminar/layout', $data);
}

公共功能索引（）{
//调用初始化方法
$config=$this->_initPagination（“/”，$this->Posts_model->get_num_rows（））；
$data=$this->Static_model->get_Static_data（）；
$data['base_url']=base_url（“/”）；
$data['pages']=$this->pages\u model->get\u pages（）；
$data['categories']=$this->categories\u model->get\u categories（）；
//使用_initPaginator方法返回的限制和偏移量
$data['posts']=$this->posts\u model->get\u posts（$config['limit']，$config['offset']）；
$this->twig->addGlobal（'siteTitle'，'My Awesome Site'）；
$this->twig->addGlobal（'maincss'，base_url（'themes/caminar/assets/css/main.css'）；
$this->twig->display（'themes/caminar/layout'，$data）；
}
公共函数作者（$authord）{
//加载和配置分页
$this->load->library（'pagination'）；
$config['base\u url']=base\u url（'/posts/byauthor/'.$authord）；
$config['query_string_segment']='page'；
$config['total\u rows']=$this->Posts\u model->Posts\u by\u author\u count（$authord）；
$config['per_page']=12；
如果（！isset（$\u GET[$config['query\u string\u segment']]））$\u GET[$config['query\u string\u segment']]<1）{
$\u GET[$config['query\u string\u segment']=1；
}
$limit=$config['每页']；
$offset=（$this->input->get（$config['query\u string\u segment'））-1）*$limit；
$this->pagination->initialize（$config）；
$data=$this->Static_model->get_Static_data（）；
$data['base_url']=base_url（“/”）；
$data['pages']=$this->pages\u model->get\u pages（）；
$data['categories']=$this->categories\u model->get\u categories（）；
$data['posts']=$this->posts\u model->get\u posts\u by\u author（$authorid，$limit，$offset）；
$data['posts\u count']=$this->posts\u model->posts\u by\u author\u count（$authord）；
$data['posts\u author']=$this->posts\u model->posts\u author（$authord）；
$this->twig->addGlobal（'siteTitle'，'My Awesome Site'）；
$this->twig->addGlobal（'maincss'，base_url（'themes/caminar/assets/css/main.css'）；
$this->twig->display（'themes/caminar/layout'，$data）；
}

然后我在posts.twig模板中使用了它：

<div class="spotlight {% if (loop.index is even) %}alt{% else %}{% endif %}">
    <div class="image flush">
        <a href="{{post.slug}}">
            <img src="{{base_url}}/assets/img/posts/{{post.post_image}}" alt="{{post.title}}" />
        </a>
    </div>
    <div class="inner">
        <h3>{{post.title}}</h3>
        <p>{{post.description}}</p>
        <div class="{% if (loop.index is even) %}text-right{% else %}text-left{% endif %}">
            <a href="{{base_url}}{{post.slug}}" class="button special small">Read More</a>
        </div>
    </div>
</div>

{{post.title}
{{post.description}}

不会做同样的事情吗？@Vickel是的，会。

public function index() {

    //call initialization method
    $config = $this->_initPagination("/", $this->Posts_model->get_num_rows());

    //use limit and offset returned by _initPaginator method
    $data['posts'] = $this->Posts_model->get_posts($config['limit'], $config['offset']);

    $this->twig->addGlobal('siteTitle', 'My Awesome Site');
    $this->twig->addGlobal('maincss', base_url('themes/caminar/assets/css/main.css'));
