How to pass parameters in index function in codeigniter

Question

here\'s an example of url: http://www.example.com/search/search-keyword

I am trying to make this work, I removed the index.php using .htaccess, search is the contro

Answer 1

class Search extends CI_Controller{

    function _remap($param) {
        $this->index($param);
    }

    function index($param){
        echo $param;
    }

}

You should then be able to access that as: /search/123123 :and the page would echo out "123123" or whatever you put in place of that.

Answer 2

This is my solution:

From CI userGuide

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

So I've created my controller in this way:

class Shortener extends CI_Controller {
function shortener() {
    parent::__construct();
}

function index($getVar) {
    echo "Get var: " . $getVar;
}

function config() {
    echo "another function";
}

function _remap($method) {
    if($method == "config") {
        $this->$method();
    }
    else {

        $this->index($method);
    }
}
}

Hope this can be helpful to someone...

BUG: if you call /shortener _remap function pass "index" to index() function...it can be solved adding an if condition or something else

Answer 3

function _remap($parameter){

        $this->_index($parameter);

}

Give it a try and tell us how it went.

Answer 4

I had to also check if some variable was passed or not - so here is the solution that I took.

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Story extends CI_Controller{

    function story() {
        parent::__construct();
    }

    function _remap($parameter){
        $this->_index($parameter);
    }  

    public function _index($story_id) {        
        if($story_id == 'index'){
            //No variable passed
            redirect('auth', 'refresh');
        }else{
            $data['title'] = "Story";
            $this->load->view('story', $data);                
        }
    }

}

Hope this helps someone!

Answer 5

I finally found a workaround since I cant simply put post variables into the URL.

What I did was create another function, then redirect it to that function.

 class Search extends CI_Controller{
   function index(){
        $search_item = $this->input-post('search_item');
        redirect("search/q/".url_title($search_item));
  }

  function q($key){
    // process search
  }
 }

Answer 6

This easiest way is just to use uri segments:

class Search extends CI_Controller{
  function index(){
    $param=$this->uri->segment(2);
    echo $param;
  }
}

Or like Madmartigan said, use routes, which is probably the better way of doing this.
