Passing parameter to controller always get "Page Not Found" - CodeIgniter - php

Question

I try to pass a parameter to my controller functions from my views but I always get "Page Not Found".
I've been looking for any solutions possible for my problem from here, here, and here but I still couldn't find working solutions and I still don't know what could be the problem. I think I've set everything right, but it's not working. Please tell me if there's something I'm doing wrong.
Here is my controller: Controll.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Controll extends CI_Controller{
public function about($thing){
$case = "About Us";
$data['page'] = $case;
$data['p'] = $thing;
print($thing);
//$this->load->view('/header/header',$data);
$this->load->view('about_us',$data);
$this->load->view('/footer/footer');
}
public function mountain_destination($thing){
$data['page'] = "Mountain Destination";
$data['p'] = $thing;
//$this->load->view('/header/header',$data);
$this->load->view('mountain_destination',$data);
$this->load->view('/footer/footer');
}
}
?>
Here's my routes setting:
$route['(:any)'] = "controll/$1";
$route['default_controller'] = "controll";
$route['404_override'] = '';
And here's one of my script called by onClick that tries to call that controller function:
function goTab(thing,tab){
switch(thing){
case "about":
$body.load("<?php echo site_url('about'); ?>/"+$(tab).text().toLowerCase().replace(/ /g,''));
break;
case "mountain":
$body.load("<?php echo site_url('mountain_destination'); ?>/"+$(tab).text().toLowerCase().replace(/ /g,''));
break;
}
My script runs well and it produces right url. For example, I put parameter "myteam" into "goTab" function, it produces link like this:
"http://127.0.0.1/about/myteam". This link's supposed to call "about" function inside my controller and pass "myteam" as parameter. But instead it returns "Page Not Found". And when I try to call "about" function without any parameters like this: "http://127.0.0.1/about", I get missing argument error like this:
Severity: Warning
Message: Missing argument 1 for Controll::about()
Filename: controllers/Controll.php
Line Number: 22
Please help me.
Thanks in advance.

Answer 1

You're not passing it to your about method. You're looking for a method called myteam within your Controll controller.
Amend your Routes to this;
$route['about/(:any)'] = 'controll/about/$1';
$route['mountain_destination/(:any)'] = 'controll/mountain_destination/$1';
Hope this helps.

You can create a variable and pass it within constructor and simply use that whenever you need as
class Controll extends CI_Controller {
private $thing;
public function __construct() {
parent::__construct();
$this->thing = $this->uri->segment(3);
}
public function about() {
$data['p'] = $this->thing;
echo $this->thing;
}
public function mountain_destination($thing) {
$data['p'] = $this->thing;
echo $this->thing;
}
}
