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.

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?

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”
