As the title, I want the CI_Controller to return value/data back to AJAX which gives the request before.
The_Controller.php
<?php
class The_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
function postSomething()
{
$isHungry = true;
if(isHunry){
return true;
}else{
return false;
}
}
}
AJAX
$(document).ready(function() {
$('#form').on('submit', function (e)
{
e.preventDefault(); // prevent page reload
$.ajax ({
type : 'POST', // hide URL
url : '/index.php/The_Controller/postSomething',
data : $('#form').serialize (),
success : function (data)
{
if(data == true)
{
alert ('He is hungry');
}
else
{
alert ('He is not hungry');
}
}
, error: function(xhr, status, error)
{
alert(status+" "+error);
}
});
e.preventDefault();
return true;
});
});
The Problem :
The AJAX code above always get FALSE for variable data. It's not get return value from postSomething function inside CI_Controller.
The Question:
I want to if(data == true) result alert ('He is hungry');, but because data not filled by return value of postSomethingfunction insideCI_Controllerso it always false. **How to get return value/data fromCI_Controller` to AJAX?**
you need to change your code a little bit. no need to return data, just echo true or echo false from your controller. Hope you will get your desired result.
