CodeIgniter AJAX login validation

Question

I have a Bootstrap modal login form. I want to perform AJAX form validation where I want to display the errors using AJAX. All of this is working perfectly but I want the form to redirect to some other view along with some data on successful login.

But here the problem is that I cannot do $('html').html(data); as it is although returning the required thing but with different font and without models and few other features.

Everything is working fine when I do the validation without AJAX but in that case, the error does not appear directly, one has to again toggle the model to view the errors.

So overall I just want to use AJAX for displaying the errors but if the error is not there I just want to display the result directly through CodeIgniter as if there was no AJAX Request.

You should replace the HTML but simple change the window location. In your success, add this line:

$.ajax({
    /*...*/
    success: function(data){
        window.location.href = "index.php/YourNewPage";
    }
    /*...*/
})

Make sure your other page is register in your route.php as well, so you can acces it via url.

Tried the same but I want to pass a php value too – pokemon Jul 10 '17 at 14:31
Thats why I am able to load the view from CodeIgniter but not from AJAX – pokemon Jul 10 '17 at 14:32
you could pass the value in `$_GET` like `window.location.href= "index.php/YourNewPage?id=2"` – Nicolas Jul 10 '17 at 14:33
And how can I access that value inside a modal – pokemon Jul 10 '17 at 14:41
in your javascript or in PHP ? – Nicolas Jul 10 '17 at 14:42
I am going to access it inside modal in a view – pokemon Jul 10 '17 at 14:46
You can retreive GET parameters in javascript., see here https://stackoverflow.com/questions/5448545/how-to-retrieve-get-parameters-from-javascript – Nicolas Jul 10 '17 at 14:46
I am receiving the value through post – pokemon Jul 10 '17 at 14:49
Can I access the value passed in URL through php(if yes then I will prefer that) – pokemon Jul 10 '17 at 14:49
yea using `$_GET['yourValue']` – Nicolas Jul 10 '17 at 14:50
you mean if I passed the value like ...?id=2 then I can access it inside view by $_POST['id'] – pokemon Jul 10 '17 at 14:51
Not `$_POST` since you are creating a get request, use `$_GET['id']` – Nicolas Jul 10 '17 at 14:51
I am using post method in AJAX – pokemon Jul 10 '17 at 14:52
So can I access the value passed in ....?id=2 format through $_GET even if I have post method in AJAX – pokemon Jul 10 '17 at 14:53
Actually I don't want the user to see the value in url – pokemon Jul 10 '17 at 14:54
you can try to save the value in SEssion and pass it to another page, see https://www.w3schools.com/php/php_sessions.asp – Nicolas Jul 10 '17 at 14:56
Can't I have something similar to `$('html').html(data);` which will load the entire page and also the javascript. This is misbehaving and not loading the modals and some other features which iss supposed to occur in javascript – pokemon Jul 10 '17 at 15:03
you could but it is a very bad idea, each page should have their own HTML and you should replace one, you should change page. – Nicolas Jul 10 '17 at 15:15
