这也正是我的要求，而且我使用了类似
$route['logued/presse-access'] = "logued/presse_access";
在我之前的项目中，我需要创建300-400路由规则，其中大多数是由于短划线到下划线的转换。
对于我的下一个项目，我热切希望避免。尽管没有在任何实时服务器中使用它，但我已经对其进行了一些快速的修改并对其进行了测试，但是它对我有用。请执行下列操作..
确保您的system / application / config / config.PHP中的subclass_prefix如下所示
$config['subclass_prefix'] = 'MY_';
然后在system / application / libraries目录中上传一个名为MY_Router.PHP的文件。
<?PHP
class MY_Router extends CI_Router {
function set_class($class)
{
//$this->class = $class;
$this->class = str_replace('-', '_', $class);
//echo 'class:'.$this->class;
}
function set_method($method)
{
// $this->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]);
}
}
现在，您可以自由使用网址，例如http://example.com/logued/presse- access，它将通过自动将破折号转换为下划线来调用适当的控制器和功能。
这是我们的Codeigniter 2解决方案，它将覆盖新的CI_Router函数：
<?PHP
class MY_Router extends CI_Router {
function set_class($class)
{
$this->class = str_replace('-', '_', $class);
}
function set_method($method)
{
$this->method = str_replace('-', '_', $method);
}
function set_directory($dir) {
$this->directory = $dir.'/';
}
function _validate_request($segments)
{
if (count($segments) == 0)
{
return $segments;
}
// Does the requested controller exist in the root folder?
if (file_exists(APPPATH.'controllers/'.str_replace('-', '_', $segments[0]).'.PHP'))
{
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);
while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($this->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('-', '_', $segments[0]).'.PHP'))
{
if ( ! empty($this->routes['404_override']))
{
$x = explode('/', $this->routes['404_override']);
$this->set_directory('');
$this->set_class($x[0]);
$this->set_method(isset($x[1]) ? $x[1] : 'index');
return $x;
}
else
{
show_404($this->fetch_directory().$segments[0]);
}
}
}
else
{
// Is the method being specified in the route?
if (strpos($this->default_controller, '/') !== FALSE)
{
$x = explode('/', $this->default_controller);
$this->set_class($x[0]);
$this->set_method($x[1]);
}
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.'.PHP'))
{
$this->directory = '';
return array();
}
}
return $segments;
}
// If we've gotten this far it means that the URI does not correlate to a valid
// controller class. We will Now see if there is an override
if ( ! empty($this->routes['404_override']))
{
$x = explode('/', $this->routes['404_override']);
$this->set_class($x[0]);
$this->set_method(isset($x[1]) ? $x[1] : 'index');
return $x;
}
// Nothing else to do at this point but show a 404
show_404($segments[0]);
}
}
现在必须放置该文件，例如application / core / MY_Router.PHP，并确保他具有subclass_prefix的定义如$config['subclass_prefix'] = 'MY_';在application / config / config.PHP中
在方法中添加了几行额外的代码_validate_request()：
while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($this->directory . $segments[0]);
$segments = array_slice($segments, 1);
}
它用于使人可以使用controllers目录内的多层子目录，而通常我们可以在controllers文件夹内使用单层子目录并可以在url中调用它。如果不需要，可以删除此代码，但对正常流程没有危害。
