Do the following...
In controller
create example.php
and leave ajax.php
like it is. And in views leave like you have already view_ajax.php
We are going to load data from example.php
with Ajax
Your ajax.php
should look like this
class ajax extends CI_Controller {
public function index()
{
$this->load->helper('url'); // if you are going to use helpher don't forget to load it ( of course if you are not loading it by default )
$this->load->view('view_ajax.php'); // in `view_ajax.php` you must have JavaScript code
}
}
JavaScript code for testing purpose write like
<script>
var xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
alert(xmlhttp.responseText);
console.log(xmlhttp.responseText);// you will see OKKK in console
}
}
xmlhttp.open("GET","../index.php/example",true); // first try `../index.php/example` ( extension depends if you enable/disable url rewrite in apache.conf ) , if this won't work then try base_url/index.php/example ( where you can specify base_url by static or with CodeIgniter helpher function )
xmlhttp.send();
</script>
Nest Step
example.php should look like this
class example extends CI_Controller {
public function index()
{
echo "OKKK";
}
}
