Passing a variable to a controller using ajax

Question

I am using ajax to pass my variable into a controller. I can see the result in the success function data but when I want to echo the posted variable, I don't see any value.

This is my ajax :

id = $(this).attr("id");        

$.ajax({
    type:'POST',
    url:'mobishopp/page', 
    data: {
      'id': id 
    },
    success:function(data) {
       alert(data);
    }
});

This is my controller:

public function page()
{
    $id= $this->input->post('id');
    echo $id;
}

In the controller when you echo $id you are not sending output to the browser window. Instead you are sending output to the success function of the ajax call. If you want it to display in the browser window you must do so in the success function.

how can i display the result in browser?

Typically that involves using JQuery to append, insert or replace part of the DOM. If that has no meaning for you start here

You would need to share the view file (html) and explain where you want this info to show up for anybody to provide help.

To see the result of ajax request and what it sent and what is received go to developer tools in google chrome in network tab select XHR then trigger the event that generate Ajax Request the request details will be shown in result such as data been send and status of the request and the response and error if there is an error

note in php to prevent execution after echo do the following

echo $id;die();

I hope my answer would be useful
