25 php regex routes codeigniter
我正在寻找一条单行路由,将虚线控制器和方法名称路由到实际的下划线控制器和方法名称.
例如URL
/controller-name/method-name-which-is-long/
会路由到
/controller_name/method_name_which_is_long/
请参阅:http://codeigniter.com/forums/viewreply/696690/这给了我一个问题:)

这也是我的要求,我正在使用像这样的路线
$route['logued/presse-access'] = "logued/presse_access";
在我之前的项目中,我需要创建300-400个路由规则,其中大多数是由于强调转换为下划线.
对于我的下一个项目,我急切地希望避免它.我做了一些快速入侵并测试了它,虽然没有在任何实时服务器中使用,它为我工作.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http://example.com/logued/presse-access等网址,它会通过自动将短划线转换为下划线来调用正确的控制器和功能.
编辑: 这是我们的Codeigniter 2解决方案,它覆盖了新的CI_Router功能:
<?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]);
}
}
现在必须将此文件放在application/core/MY_Router.php中,并确保他$config['subclass_prefix'] = 'MY_';在application/config/config.php中定义了subclass_prefix
在方法中添加了几行额外的代码_validate_request():
while(count($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);
}
它的使用是为了可以使用控制器目录中的多级子目录,而通常我们可以使用控制器文件夹中的单级子目录,并可以在url中调用它.如果没有必要,可以删除此代码,但它对正常流程没有任何影响.

升级到CodeIgniter 2之后回到这个问题.这是一个比接受的答案更强大的解决方案,因为它将在CodeIgniter核心更新中存活.
<?php
class MY_Router extends CI_Router
{
public function set_class($class)
{
parent::set_class($this->_repl($class));
}
public function set_method($method)
{
parent::set_method($this->_repl($method));
}
public function _validate_request($segments)
{
if (isset($segments[0]))
$segments[0] = $this->_repl($segments[0]);
if (isset($segments[1]))
$segments[1] = $this->_repl($segments[1]);
return parent::_validate_request($segments);
}
private function _repl($s)
{
return str_replace('-', '_', $s);
}
}
它应该保存为application/core/MY_Router.php.现在,您可以在控制器和方法名称中包含下划线,例如Abc_Def(在文件中abc_def.php)并使用URL引用它们/abc-def.
实际上这在Codeigniter 3中是原生的,只需在路径文件中执行此操作即可
$route['translate_uri_dashes'] = TRUE;
它将自动为控制器和方法执行此操作.
请将此答案投票,因为它是最新的
