In my controller file (ProjectsController) I have the following function:

And finally I have the view (elements/assets):

As far as I know, there is no update option in the jQuery ajax api. Instead, you should add the success callback and populate the data there:

There is no update-option, just as jeremyharris already pointed out.

If you only want to fill an element with HTML loaded via AJAX, you can also use $.load():

It's basically a shorthand for the corresponding $.ajax() call, and will automatically issue a POST request if the data parameter is present.

I have a basic ajax form on my site utilizing the Js helper, it works fine but when there are validation errors the update callback duplicates the entire page inside of my success div.

Success div:

Submit button:

I just tested your application by using your zip file.

What I observed is that this is not the whole page that is put inside your #success div, but only the content of the Posts/add.ctp view.So basically this means the RequestHandler does its job correctly, meaning the layout that is used is the 'ajax' layout.To get rid of anything else that the form, the add.ctp page should not contain anything else that the form. In your case Posts/add.ctp contains navigation links, and that's why they get duplicated.

That said, what the submit button does currently is getting the content of Posts/add.ctp view and insert it in your empty #success div. But you never remove the form that was already on the page.What you could do is updating the content of a div that contains your first form, or even the content of the whole Posts/add.ctp view.

In your case, simply updating the #content instead of the #success div could maybe suit your needs:

nIcOnIcO

I ran into the same problem. Although nIcO seems to be giving the solution, in my case it didn't helped, because the success message Drawrdesign wants, is still not being rendered.

So, I looked at your zip file and found the solution. There are two ajax calls defined: 1) the .blur and 2) the .bind. 1) is used for validation of the fields and submits data through AJAX to the validate_form() function of the PostsController. And 2) is used to observe the click event of the submit button and sends data to the add() function of the PostsController.

This problem occurs at 2), because you click the Submit button. So, you should be looking at the add() function of the PostsController. In the validate_form() of 1) function you added the line:

And this is the solution. Because where CakePHP automatically renders the view, you don't want it to happen, because of AJAX. So, in case 1) it's done, it should be added to the add() function in the case 2) like this:

So, it's stop of (auto)rendering the add.ctp in the div='#success', and your other messages of 'sending.' and 'succes.ctp' are still begin displayed.

PS. @Drawrdesign, did you by any chance followed an instruction video of andrewperk?

Ajax

djmenkvelddjmenkveld

in the Ajax Request handling set the layout to ajax. So the error message will be rendered with the ajax layout and not with the default layout.

Make sure you are either:

Using the RequestHandler component (preferred):

or manually set the layout to 'ajax' in your action:

Install hp 6122 vista • Start to execute the setup file and you have to follow the installation wizard. • Follow the steps which appear on the screen until finish.

Ajax Form

Request handler will set the layout to ajax automatically when it detects an Ajax request.

The ajax layout doesn't return anything other than the rendered view.

Ajax Form Submission

Hello firstly it seems you are using cake 2 lib and using 1.3 code which will probably work but is in parts deprecated may be work checking the migration guide . The console tool can also upgrade your code to 2.0/2.1 .

Secondly surely you do want to render a view and an empty layout? $errors is defined in Views/Posts/validate_form.ctp. You are setting $errors and then not rendering the view. Remove setting the auto render to false and place at the top of you controller action.

Any good?
