Views, JSON, and HTML - El Forum - 11-09-2012

I'm new to CodeIgniter and MVC. I'm having some trouble trying to figure out the best place to put a snippet of HTML. I know that the answer is probably in the View area. Here is the problem, sometimes I want the snippet of HTML to be called normally, but other times I need AJAX to call it and to return it as JSON. How do I accomplish this?
On my webpage I have a "Add" button. This calls the Ajax and should return with some JSON that contains the HTML and the ID of the HTML.
This seems like this should be a common thing that people want to do. How do I accomplish this?

Lots of ways really, but you could just have a method in your controller that you call with your ajax request and have it return that view.
Code:
function send_view($view = '')
{
if ($this->input->is_ajax_request() && $view !== '')
{
$this->load->view($view);
}
}Then send your ajax request to
http://yoursite.com/your_controller/send_view/view_name
If you need to send extra parameters you can do that using POST ajax method and enter them there in the data portion and retrieve them with $this->input->post($field_name) in your "view_name" method where you can do what you need to do and pass them to the load::view()
You could also send them as extra URL segments (instead of data in post) and have it automatically passed to the send_view() method like the example shows with $view.

The problem is that:
$this->load->view($view);
just dumps the HTML to the screen. I need to put it in a JSON object and then download it. So something like this:
{'html': '<h1>html here</h1>', 'id': 44}
I want to reuse code here. Sometimes I just want to return the straight HTML and other times I want to put it in JSON and return it.
How?

Code:
function send_view($view = '')
{
if ($this->input->is_ajax_request())
{
$data['view_html'] = $this->load->view($view, array(), TRUE);
echo json_encode($data);
exit;
}
else
{
$this->load->view($view);
}

AWESOME! Did not know there was a third param for returning the HTML in the "view" function.
Thank you so much!

But the user's guide says so. Hence reading the guide may really be a pain in the you-know-where but it will save you some "bad experiences"
