codeigniter中的漂亮网址设置

我有控制器'package'的url,函数'tour_package'和参数'1'。 http://www.mysite.in/package/tour_packages/1 这里参数设置为id。我需要用相应的url字符串更改它 http://www.mysite.in/package/tour_packages/American

和另一个例子: http://www.mysite.in/package/tour_packages/2http://www.mysite.in/package/tour_packages/African

如何做到这一点?

1 个答案:

答案 0 :(得分:1)

首先,我会更改网址链接以使用 url_title()(网址助手)。如果您使用我认为是数据库调用的ID的文本值创建查询,这将为您提供类似

的内容

(例如,如果id 1的记录是name =“America”);

echo 'http://www.mysite.in/package/tour-packages/'.url_title($name);

会给予;

http://www.mysite.in/package/tour-packages/American

如果您随后添加此扩展路由器类,它将自动将破折号重新格式化为下划线。

<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Router extends CI_Router {

    function set_class($class) {
        $this->class = str_replace('-', '_', $class);
    }

    function set_method($method) {
        $this->method = str_replace('-', '_', $method);
    }

    function _validate_request($segments) {
        // Does the requested controller exist in the root folder?
        if (file_exists(APPPATH.'controllers/'.str_replace('-', '_', $segments[0]).EXT)) {
            return $segments;
        }
        // Is the controller in a sub-folder?
        if (is_dir(APPPATH.'controllers/'.$segments[0])) {       
            // Set the directory and remove it from the segment array
            $this->set_directory($segments[0]);
            $segments = array_slice($segments, 1);

            if (count($segments) > 0) {
                // Does the requested controller exist in the sub-folder?
                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().str_replace('-', '_', $segments[0]).EXT)) {
                    show_404($this->fetch_directory().$segments[0]);
                }
            } else {
                $this->set_class($this->default_controller);
                $this->set_method('index');

                // Does the default controller exist in the sub-folder?
                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT)) {
                    $this->directory = '';
                    return array();
                }

            }

            return $segments;
        }

        // Can't find the requested controller...
        show_404($segments[0]);
    }
}

然后你可以在路由文件中添加一个条目(在config中);类似的东西;

$route['package/tour_package/(:any)'] = "package/lookup_by_name/$1";

然后,您需要在包控制器中创建一个名为 lookup_by_name($ name)的方法。 此方法需要对数据库执行sql查询,从中获取名称值的id。然后,您可以继续加载视图或执行任何操作。

E.g

public function lookup_by_id($name) {
   // sql to get id from database record

   // load the view?
   $this->view($id);
}

public function view($id) {
   // sql to load full record from id
   $this->load->view('foo', $data);
}
