Ignoring Codeigniter's _remap for certain URLs? - codeigniter

Question

I use Codeigniter's _remap function to remap all urls to www.website.com. This works for 99% of cases, but I'd like it to ignore certain URLS (specifically /admin,/contact,/submit,/top,/browse). These URLs have content I'd like to display.
How would I achieve this?
public function _remap($urlname)
{
if($urlname == "index") {
// If this is the index, redirect to the most recent startup
redirect("s/".$this->Startup_model->getMostRecent(), 'refresh');
} else {
// If they didn't go to the index, find the startup they were after
$id = $this->Startup_model->matchName($urlname);
// Check to see if the name they entered was a real startup, if not redirect to missing page
if($id == null) {
$data['urlname'] = $urlname;
$this->load->view('header/header');
$this->load->view('content/missing', $data);
$this->load->view('footer/footer');
} else {
// They got the name right! Load the page...
$data['values'] = $this->Startup_model->buildStartup($id);
// If there was no next startup avaiable, pass that info through
$next = $this->Startup_model->findNext($id);
if($next == null) {
$next = '343z61v';
}
// If there was no previous startup avaiable, pass that info through
$previous = $this->Startup_model->findPrevious($id);
if($previous == null) {
$previous = '343z61v';
}
$data['next'] = $next;
$data['previous'] = $previous;
$this->load->view('header/header');
$this->load->view('content/startup', $data);
$this->load->view('footer/footer');
}
}
}

Try this:
function _remap($urlname, $params = array())
{
if(is_callable(array($this, $urlname))){ //If the function exists, is called, if not using the usual
return call_user_func_array(array(&$this, $urlname), $params);
}elseif($urlname == "index") {
// If this is the index, redirect to the most recent startup
redirect("s/".$this->Startup_model->getMostRecent(), 'refresh');
} else {
// If they didn't go to the index, find the startup they were after
$id = $this->Startup_model->matchName($urlname);
// Check to see if the name they entered was a real startup, if not redirect to missing page
if($id == null) {
$data['urlname'] = $urlname;
$this->load->view('header/header');
$this->load->view('content/missing', $data);
$this->load->view('footer/footer');
} else {
// They got the name right! Load the page...
$data['values'] = $this->Startup_model->buildStartup($id);
// If there was no next startup avaiable, pass that info through
$next = $this->Startup_model->findNext($id);
if($next == null) {
$next = '343z61v';
}
// If there was no previous startup avaiable, pass that info through
$previous = $this->Startup_model->findPrevious($id);
if($previous == null) {
$previous = '343z61v';
}
$data['next'] = $next;
$data['previous'] = $previous;
$this->load->view('header/header');
$this->load->view('content/startup', $data);
$this->load->view('footer/footer');
}
}
}
Note:
Function index() should not exist

So you're asking how to selectively not remap certain urls? If so, add this to your if statement before the else:
else if (in_array($urlname, array('admin', 'contact', 'etc')))
{
$this->$urlname;
}
