CodeIgniter：嵌套视图中的表单操作

Question

I have a little problem with codeigniter and form.

I'm, working on a project, where security is very important. I use codeigniter and bootstrap. I have main view, which includes navbar and some other html. In that main view i have <div id="change"> which i am changing via button group. With those buttons I am calling functions in controller which contains $this->load->view('pages/something', $data); When i press on one of those buttons <div id="change"> is changed and in it, a view, is shown and link is not changed, so main view remains as it is. But when one of those buttons is pressed, view with form is shown. In it i use form_open('controller/function', $attributes); . Problem is, that when i submit this form, link is changed and main view is not on screen anymore.

How can i achieve, that when i will submit form, all that will be changed is just <div id="change"> and not whole site.

I know i am bad in English, sorry. I appreciate any help. Thanks!

Answer 1

You want to refresh PART of the page and not the WHOLE page ? Maybe you need AJAX.

also, to make the link not changed, you have to change

config/routes.php

like this :

$routes['controller/method'] = "your link";

Hope it helps

You can submit the form with AJAX, here's a basic example with jQuery:

// this is the id of the form
$("#idForm").submit(function() {

    var url = "path/to/your/script"; // the script where you handle the form input.

    $.ajax({
        type: "POST",
        url: url,
        data: $("#idForm").serialize(), // serializes the form's elements.
        success: function(data) {
             // 'data' is the response from the php script.
             // Update <div id="change"> here.
        }
    });

    return false; // avoid to execute the actual submit of the form. (This stops the URL changing).
});
