Get Parameters in The Url with Codeigniter

GET parameters in the URL with CodeIgniter

When I first started working with CodeIgniter, not using GET really threw me off as well. But then I realized that you can simulate GET parameters by manipulating the URI using the built-in URI Class. It's fantastic and it makes your URLs look better.

Or if you really need GETs working you can put this into your controller:

parse_str($_SERVER['QUERY_STRING'], $_GET); 

Which will put the variables back into the GET array.

How to get the parameter from url in codeigniter?

You can use $this->uri->segment(n);

You need to do some changes in route in order to allow the code igniter to receive the parameter in your controller

$route['uri-(:any)/(:num)'] = "controller/function/$1/$2";

OR

$route['uri-(:any)'] = "controller/function/$1";

in your controller do some changes

<?php
 if (!defined('BASEPATH'))
   exit('No direct script access allowed');

 class controller extends CI_Controller 
 {
    function function($parameter1 = null, $parameter2 = null) 
    {
       ........
    }
 }

Cant get URL parameters in CodeIgniter

Use this (if this is not HMVC)

in route.php

# You may need first route since you're accepting null on method
$route['mymethode] = 'mycontroller/mymethode';
$route['mymethode/(:num)'] = 'mycontroller/mymethode/$1';

In AJAX

url: http://mydomein.com/mymethode/123,

Make sure your sites run without index.php

In controller

public function mymethode($listid=null)

Passing multiple variables in URL using codeigniter

You can use uri to retrieve values in your url

Here is an example

public function getproduct()
{
  $productID =  $this->uri->segment(3);
  $factoryID =  $this->uri->segment(4);
  // ProductID will be 25
  // Factory ID will be 45
}

Then you can just use the values as you please

How to get the URL paramters inside view using codeigniter

You can use $this->input->get('coupon'); to get the value of url parameter.
But, I suggest you to get the parameter value with $this->input->get('coupon',TRUE); to applying XSS Security directly.

How to get id from URL in codeigniter?

if you have to pass the value you should enter url like this

localhost/yoururl/index.php/products_controller/delete_controller/70

and in controller function you can read like this

function delete_controller( $product_id = NULL ) {
  echo $product_id;
}

How to pass multiple parameters from url in Codeigniter?

Considering it for SEO purpose, I think it would be safe to leave just the category and the subcategory in the url, and leave the rest as GET variable :

public function show_category($category = false, $subcategory = false)
{
    $state = $_GET['state'];
    $city = $_GET['city'];
   // Showing ads...
}

then you can skip the category and subcategory url segment, and send the state and city as query string :

localhost/show_category/category/subcategory?state=x&city=y

Send a url parameter to a site in codeigniter

If I am understanding correctly you have a folder called modules inside of your controllers folder. This answer is assuming that you have gotten rid of the index.php? part of your URI.

Of course we know that a basic controller should look like this (so your Manage.php should look something like this:

[IMPORTANT: Controllers filenames should start with an uppercase and match the class name]

Class Manage extends CI_Controller{

    public function __construct(){
        parent::__construct();
        // add libraries/models
    }

    public function index(){
        // index logic
    }

    public function newMethod($param){
        //The method used to capture your parameter.
    }
}

If that is set up properly, then you should be able to go into routes.php and add something like this:

$route['admin/modules/(:num)'] = 'modules/Manage/newMethod/$1';

Then you should be able to visit www.yoursitename.com/admin/modules/#INSERT-A-NUMBER and get what you want.

Alternatively you can change the route so that it accepts anything as a parameter and not just a number. That looks like this:

$route['admin/modules/(:any)'] = 'modules/Manage/newMethod/$1';

Hope this helps!
