How to pass parameter after baseurl in codeigniter?

问题

Base URL: http://localhost/f1/

and I am passing parameter in URL like: http://localhost/f1/user1

and I am trying to print

function index(){
    echo $this->uri->segment(2);
}

I want to print User1 in the controller. How to achieve this?

回答1:

Config your rout and add this:

$route['Controller_Name/(:any)'] = 'Controller_Name/index/$1';

Here you go with your controller

class Controller_Name extends CI_Controller {
  function index($prm){
    echo $prm;
  }
}

Have fun.... you can have how many uri you want....

Read here https://www.codeigniter.com/userguide3/general/controllers.html -> Passing URI Segments to your methods

/products/shoes/sandals/123

<?php
class Products extends CI_Controller {

        public function shoes($sandals, $id)
        {
                echo $sandals;
                echo $id;
        }
}

After base_url segemnts/parameter can get like this

Make sure base_url and URL helper is set in the application/config/config.php and application/config/autoload.php file respectively

Suppose, calling a function with a anchor tag

<a href="<?= base_url('HomeController/index/'.$url1)?> ">Index</a>

In the above line, HomeController is controller name, index in the function name and $url1 is the parameter

class HomeController extends CI_Controller {

    public function index($url1){
         echo $url1;
    }
}

Also, $this->uri->segment() can be used.

What i understood from your question is that you want a remap without using your method and pass the parameter directly after your controller?

You can user _remap and check if it matched a method process it normally or pass it to your default method directly and now you won't need to use index in your url as you intended.

public function _remap($method)
{
        if ($method === 'some_method_in_your_controller')
        {
                $this->$method();
        }
        else
        {
                $this->index($method);
        }
}

Now lets say your url is like this http://localhost/controller/parameter then if this parameter matches a method it will call that method if not it will pass it as a parameter to you index.

回答5:

define your controller in config/routes.php.it will call your index function by default.

$route['default_controller'] = 'controllername';

回答6:

check whether you loaded the url helper. Only then it will work as expected. Either auto-load it or call it in the controller.
