i need to get the vLUE 123 here

回答1:

In Codeigniter you can simply do

public function get_radius($lang)
{
   var_dump($lang); //will output "lang=123"
}

So your link could be simplified to http://localhost/directory/c_service/get_radius/123 if you don't want to do something like explode('=', $lang) to get your value.

You should however also consider adding a default value public function get_radius($lang=0) if the link is opened without a parameter.

Adding more variables is as easy as public function get_radius($lang, $other) for http://localhost/directory/c_service/get_radius/123/other

You can use:

<?php
$this->input->get('lang', TRUE);
?>

The TRUE is to turn on XSS filtering, which you do want turned on.

Check out https://www.codeigniter.com/user_guide/libraries/input.html for more info.

enable url helper in config/autoload.php

$autoload['helper'] = array('url');

or load url helper in desired controller or its method

$this->load->helper('url');

and then use below in controller

$this->uri->segment(3);

the above line will get you the first parameter, increasing value will get you parameters

$this->uri->segment(4);

will get you second and so on.

hope this helps you

I manage it and i check it thats working first load the url

$this->load->helper('url');
$this->uri->segment(3);

example : http://localhost/schoolmanagement/student/studentviewlist/541

if you use $this->uri->segment(3); you get (541) id

The above line will get you the first parameter, increasing value will get you parameters

$this->uri->segment(4);
