Codeigniter routes with arguments - php

I want something like this but it wont work, that means I am doing it wrong.
$route['print/:num'] = "user/doprint/goprint/:num";
Let me explain. I have a controller doprint under user folder and the goprint is a method inside doprint which accepts a id as argument. Now i dont want the users to visit it by mydomain.com/user/doprint/goprint/2. I want them to visit it as mydomain.com/print/2.
my controller is as below
class Doprint extends User_Controller {
public function index()
{
$data['subview'] = 'print';
$this->load->view('main_layout', $data);
}
public function goprint($id=NULL)
{
$data['model'] = $this->usermodel_model->get($id);
$data['subview'] = 'print';
$this->load->view('main_layout', $data);
}
}

The route rule syntax is (per the documentation):
$route['print/(:num)'] = "user/doprint/goprint/$1";

How to show sub router?

Suppose I have this controller:
class Site extends CI_Controller {
public function __constructor()
{
parent::__constructor();
echo 'test';
}
public function index()
{
$view['site'] = true;
$view['view_home'] = lang('home');
$view['view_home_url'] = base_url();
$view['view_name'] = lang('home');
$view['content'] = 'site/home';
$this->load->view('partials/template', $view);
}
public function association()
{
echo 'test';
}
}
when I type: http://localhost/mysite/association I get 404. Essentially I would like to use the same controller Site which is the default controller, to load multiple routers. How can I do this?
You are using codeigniter and you can't access url lik below as you haven't defined any routes for that. http://localhost/mysite/association . You will have to go url like
http://localhost/mysite/site/association //sometimes need index.php
if you don't configure it. first parameter is the controller and second one is a method
For going to your custom URL you will have to go to application/config/routes.php and define your new custom
route $route['association'] = 'site/association';
You can also define like below routes and access from browser
$route['association/url1/url2/url2'] = 'site/association'; //simple
Hope that you have got your answer

How to pass data from controller to models in codeigniter

I passed parameter from view to controller via URL. Now I want to send it from controller to model so that I can use it to pick data from tables. Here is my code:
controller:
function view(){
if(isset($_GET['r'])) {
$rank = $_GET['r'];
}
$rank=$this->uri->segment($rank);
$this->load->model('names_rank');
$data=$this->names_rank->get_names($rank);
print_r($rank);
}
model:
function get_names($rank){
$this->db->select('u.*,v.*');
$this->db->from('unit_member u, Vyeo v');
$this->db->where('v.fno = u.fno');
$this->db->where('u.present = ""');
$this->db->where('v.rank', $rank);
$this->db->where('v.date_of_end="0000-00-00"');
$query = $this->db->get();
return $query->result_array();
}
this is the result:
A PHP Error was encountered Severity: Warning Message: Missing
argument 1 for Names_rank::get_names(), called in
C:\xampp\htdocs\unit\application\controllers\names.php on line 32 and
defined
This will work to send to model but your code isn't understandable for me, you re-declare the variable after setting it in the IF? are you trying to print_r() the output from the model?
I think you are trying to achieve this maybe?
function view() {
if(isset($_GET['r'])) {
$rank = $_GET['r'];
}else{
$rank = $this->uri->segment($rank);
}
$this->load->model('names_rank');
$data = $this->names_rank->get_names($rank);
print_r($data);
}
You can pass a Parameter to your model. First you have to call your model within your controller if you not enable it on autoload.
Your Model:
<?php
class AwesomeModel extends CI_Model
{
publif function do_work($param, $anotherParam)
{
//code here
}
}
Then your controller:
<?php
class AwesomeController extends CI_Controller
{
public function __construct()
{
/*
* load in constructor so not need to recall every time you want use it
* second parameter is model renaming (optional)
*/
$this->load->model('AwesomeModel', 'awe');
}
public function pass_data()
{
$this->awe->do_work($param1, $param2);
}
?>
Thats all.

Codeigniter route not work with parameters

I have controller Post with methods index, add and delete. I create routes rule for this actions:
$route['posts'] = 'post/index'; // <-- Work
$route['post-add'] = 'post/add';// <-- Work
$route['post-delete/(:num)'] = 'post/delete/$1'; // <-- Not Work
First route www.example.com/posts work good, and second with /post-add work. But when i call post-delete/5 that not work, all time i get 404 Not Fount.
Here is controller
class Post extends MY_Controller
{
public function index()
{
//.
}
public function add()
{
//.
}
public function delete($id)
{
echo "Delete post #ID =" $id;
}
}
I have only problem with delete route i dont know whay he dont accept that parameter.
Work:
www.example.com/posts
www.example.com/add
Not work:
www.example.com/delete/1
What can be problem?
Add it to route file
$route['delete/(:num)'] = 'post/delete/$1'

Codeigniter Routing - Using it too much?

I'm new to Codeigniter, and I'm trying to get accustomed to it by converting an old site into CI.
One thing I'm having trouble understand is the routing. If I don't want to have my url structure like /controller/method/id, I have to change it to something like $route['controller/(:num)'] = "controller/method/$1"; in routes.php. It just seems inefficient to me, is there something else I should be doing?
For example, on my site, the urls are /game/4242 and /player/SomeDude
Well, routing is effecient - the alternative is remapping your controllers.
Let's take a look at both possibilities.
An imaginary situtation:
At a later point, you'd like to allow your users to show badges/medals/achievements/something on their profile.
With routing, you can achieve it like this:
$route['player/(:any)/(:any)'] = "player/show_$2/$1";
$route['player/(:any)'] = "player/show_profile/$1";
And your controller could in turn look like this:
class Player extends CI_Controller
{
public function show_profile( $username )
{
// the profile info
}
public function show_badges( $username )
{
// the profiles badges
}
public function show_scores( $username )
{
// the profiles scores
}
}
}
Basically, this allows you to simply add another method in your controller prefixing the method with show_ (like public method show_friends( $username ) )and you can access it instantly by going to /player/SomeDude/friends
Looking at the alternative, remapping your controller would allow you not to use routes, but write a controller like this:
class Player extends CI_Controller
{
public function _remap($username, $params = array())
{
if(empty($username))
show_404();
$this->user = $this->user_model->find($username);
if(count($params) == 0)
$method = 'index';
else
$method = $params[0];
unset($params[0]); //No need to send the method along as a parameter
$method = 'process_'.$method;
if (method_exists($this, $method))
{
return call_user_func_array(array($this, $method), $params);
}
show_404();
}
public method process_index()
{
// the profile info
}
public method process_badges()
{
// the profiles badges
}
public method process_scores()
{
// the profiles scores
}
}
Personally, I like routing. I think it's transparent and makes my controllers look cleaner.

URL segment - User Profiles - Codeigniter

I'm trying to create user profiles for my site where the URL is something like
mysite.com/user/ChrisSalij
Currently my controller looks like so:
<?php
class User extends Controller {
function user(){
parent::Controller();
}
function index(){
$data['username'] = $this->uri->segment(2);
if($data['username'] == FALSE) {
/*load default profile page*/
} else {
/*access the database and get info for $data['username']*/
/*Load profile page with said info*/
}//End of Else
}//End of function
}//End of Class
?>
At the moment I'm getting a 404 error whenever i go to;
mysite.com/user/ChrisSalij
I think this is because it is expecting there to be a method called ChrisSalij.
Though I'm sure I'm misusing the $this->uri->segment(); command too
Any help would be appreciated.
Thanks
It's because the controller is looking for a function called ChrisSalij.
A few ways to solve this:
change
function index(){
$data['username'] = $this->uri->segment(2);
to be
function index($username){
$data['username'] = $username;
and use the URL of mysite.com/user/index/ChrisSalij
if you don't like the idea of the index being in the URL you could change the function to be called a profile or the like, or look into using routing
and use something along the lines of
$route['user/(:any)'] = "user/index/$1";
to correctly map the URL of mysite.com/user/ChrisSalij
